INDIAN LEGENDS (Continued)
BELLE ISLE—Nationally known island park in the Motor City, is
the basis for an ancient Indian legend. It concerns a great warrior's
daughter, renowned and coveted for her beauty, even by the Four
Winds. To guard her, the great warrior hid his daughter in a bark
hut on Belle Isle and placed a ring of poisonous serpents around the
island. With this protection, the beautiful maiden lived her life
unharmed. Regardless of the ancient Indian tale, Belle Isle is one of the most beau
tiful city parks in the country.
PIPESTONE QUARRY-Here is perhaps the source of the most
widely accepted legend among North American Indians. The chiefs of
the warring tribes of all the earth were called into council at this
point by the Great Spirit. The great council was held in this canyon,
its quartzite stone red with the blood of slain warriors. There, the
tribes agreed to forego war. The Great Spirit fashioned a pipe from a
shaft of the stone in which red willow bark was smoked. Each great chief smoked
this first pipe of peace as the seal of agreement. Ever since, the symbol and tradi
tion of the peace pipe has been a universal custom of the Indians. The Pipestone
Quarry was neutral ground by general agreement, and, from far and near, the tribes
sent delegations to secure supplies of the red stone for ceremonial pipes.

INDIAN LEGENDS (Continued)
MISSISSIPPI RIVER—The Father of Waters, and the largest
river system of the continent.
The unwritten history of the Choctaws and the Chickasaws identifies
the Mississippi as one of their discoveries in their eastward migration
from Old Mexico. They were following a symbol given them by the
Great Spirit. The greatest body of water they had ever seen, their
medicine men named it "Misha Sipokni," meaning "Beyond the ages—the Father
of all its kind."
SPANISH MOSS—The trailing tendrils of Spanish Moss on southern
trees is a reminder of an ancient Seminole story involving a blood
feud between the Creeks and the Seminoles. Tradition relates the
tale of a sorrowful Indian maiden whose bridegroom was killed in
the feud before their marriage. Cutting off her long raven hair as
a mark of her grief, she is reputed to have hung the tresses upon the
tree branches. Today, her long hair, now gray with age, still waves in the breeze
as Spanish Moss.
NATURAL BRIDGE—Scenic highlight in Virginia's mountains. An
ancient Indian story relates the trials of Indian villagers suddenly
attacked by a much larger war party and trapped at the edge of a
200-foot ravine. The Great Spirit, in his constant watch over the
weak and helpless, bridged the chasm with a solid stone causeway
over which the trapped Indians were able to get to safety. Ever
since, Indians have related the story of the Great Spirit's solicitude for the "little
people."
Standing 215 feet high and 90 feet across, the Natural Bridge is a visiting "must"
for tourists in the valley between the Blue Ridge and the Alleghenies.
WHITE MOUNTAINS—In Indian tradition, the White Moun
tains were raised by the Great Spirit as an ever-plenty garden for
the Indians to protect them from famine and suffering. Game was
always to be found there provided they took only what was needed.
However, it was understood that no Indian was ever to climb the
heights where the Great Spirit resided. Tradition has it that trespassers
never returned and wandered forever with their mourning cries heard in the wailing
winds of winter storms.
The White Mountains, a natural wonder of New Hampshire, is an ever popular
scenic spot for motor travelers in New England.

Jndian Cegends
CRATER LAKE—A truly beautiful mountain lake in the heart of
the Coast Range in Oregon. Ancient Indian tradition holds that the
lake was a scene of battle between the Good Spirit and Evil Spirit
in which the Good Spirit finally won out. The Eagle and Antelope
were allies of the Good Spirit in overcoming the Bad One. The Evil
Spirit is reputed to have been buried in the lake and an island is
supposed to be the head of the Evil One.
Six miles wide and two thousand feet deep, Crater Lake is set in a pre-historic
volcano without inlet or outlet. Its brilliant blue waters dazzle visitors.
JlT. SHASTA—A majestic and inspiring scenic point in northern
California. Its imposing, snow-capped grandeur, standing alone,
naturally made it a focal point in Indian lore. Their belief is that the
Great Spirit raised Mt. Shasta in order to provide himself with a
stepping stone from the Heavens to the earth. Finding the earth cold
and dreary, he created the sun to give warmth, gave each living
thing its color and to each bird, a song. Originally, the grizzly bear was the master
of all creatures. To the Indian, he remains a symbol of veneration associated with
this legend.
BRYCE CANYON—The many colorful minarets and rock formations
in this natural mountain wonderland are a memorial to an Indian
tale, hoary with age. The tale of the Canyon involves creatures and
animals who had been led to safety in this beauty spot by a legendary
figure known as the Coyote. After finding themselves safe, they
became ungrateful to their benefactor. Angry at their unbecoming
actions, he turned all of them into colored stone to be eternal reminders of the
penalties for ingratitude. They remain today as rocky memorials to this event.
In the heart of the Rockies, in southwestern Utah, Bryce Canyon is now a great
national park and a favorite with tourists in our mountain states.
SHIP ROCK—In extreme northwestern New Mexico, is a famous
Navajo Indian landmark. It is reputed to be the original home of
the Navajo. After a ceaseless and bloody war against stronger
enemies, the Navajo people were assembled on the heights by the
Supreme Being and, enormous peak and all, were transported through
the air to the present location. The eagle and the owl are symbols
of the event to the Navajo people.

Owner Service Policy
Along with this Owner's Guide, you
received an Owner Service Policy,
which was filled out by the dealer
upon delivery of your car. Read this
Service Policy carefully. It is recom
mended that you keep it in the glove
compartment.
The coupon attached to your Owner Service Policy entitles you to an
inspection and certain other services on your car at the end of 2,000
miles, provided the coupon is presented within 2500 miles of
car Operation. This inspection is to make any changes or corrections
which may become necessary during the break-in period. These
services will be performed for you without charge (except for chassis
lubrication, engine oil and other lubricants) by the dealer from whom
you purchased your car. (In case you are touring or have changed
your residence, any authorized Pontiac dealer in the United States
or Canada will perform this inspection upon presentation of the
Owner Service Policy and Coupon.) By making an appointment ahead
of time, you can avoid rush periods and get the inspection the day
you want it.
Pontiac dealers everywhere stand ready to provide you with the best
possible service at all times. It is their responsibility to assure your
continued satisfaction with your car. But you, too, have a responsi
bility as an owner—the responsibility of giving your Pontiac the
reasonable care and attention which it deserves.

Car Wreak-fa and
Serial Numbers
New Car Break-In—When starting out with your new car, you
should drive moderately for 10 to 15 minutes to allow time for the
engine, transmission, and rear axle to warm up. Speeds can then be
increased as shown below:
CAR SPEED—First 200 miles not to exceed 50 miles per hour.
Second 200 miles not to exceed 60 miles per hour.
Third 200 miles not to exceed 70 miles per hour.
After your car has warmed up, speed should be increased gradually
to the maximums in the above schedule, held there for a short dis
tance, then gradually decreased to a slower speed for a short distance.
Driving at speeds up to 50 miles per hour, even for distances greater
than the 200-mile period, will not "break-in" your car for sustained
high speed driving. Sustained high speed driving should not be
undertaken until the above schedule of maximum speeds (or its
equivalent) is completed.
NOTE: Brakes, too, need "breaking-in". Avoid fast stops during the first
few hundred miles.
ENGINE AND CAR SERIAL NUMBER—The car serial number is located on a
plate which is attached to the left front pillar post. The engine serial number is
stamped on the right hand front face of the block. The engine number is the same
as the car serial number. (Serial number ).
STYLE, PAINT, AND TRIM NUMBERS—The style, paint and trim numbers
are stamped on the plate attached to the right side of the cowl just under the rear edge
of the hood.
Style number Paint number Trim number
KEY NUMBERS—The octagonal handled keys fit the front door and ignition locks
on all models, and the rear door on station wagons. The oval handled keys fit the
glove compartment lock on all models, and the rear deck compartment lock on
passenger car models. Octagonal key number Oval key num
ber Refer to page 8 for removal of key number from key.
STARTING THE ENGINE—Hydra-Matic equipped cars, see page 11. Synchro-
Mesh equipped cars, see page 15.
WHERE TO PUT YOUR OWNER'S GUIDE—Slip this Owner's Guide into the
clip in the roof of the glove compartment for ready reference. This clip is also handy
for holding maps and other papers.
If it becomes necessary for you to order any part or correspond with your
dealer or the factory about your car, you can avoid any possible misunder
standing by giving the SERIAL, STYLE and PAINT numbers of your car.

Instruments and Controls
The location of the controls and instruments on your Pontiac has
been planned with the idea of comfort and convenience for the driver,
which also contributes to greater safety.
SPEEDOMETER-The speedometer
indicates the forward speed of the car
in miles per hour. As the speed increases
a continuous luminescent red band ad
vances ending at the speed being
traveled, to subtly warn against speed
ing.
BATTERY INDICATOR-The battery indi
cator shows the current flow to and from the
battery. Electrical current going from the
generator to the battery indicates on the
"C" (charge) side. The indicator will show
a "D" (discharge) when more current is
being consumed than is being received from
«r 11 in—in mini■■■ the generator.
WATER TEMPERATURE INDICATOR—The temperature of the
cooling water in your engine is shown by the water temperature
indicator. When the engine first warms up the temperature will
register slightly higher than when engine reaches operating tempera
ture. If the temperature indicator needle goes to the "H" (hot) mark,
you should have the cause located immediately. (For details on the
care of the Pontiac cooling system see page 24.)
FUEL GAUGE—The fuel gauge indicates the quantity of gasoline
in the tank only when the ignition is turned on. When the ignition is
turned off the pointer drops back beyond the empty mark. The letters
"E" and "F" on the fuel gauge are used to point out direction of
indicator travel only. Gauge readings are made
from the three dots on the gauge face. The left
hand dot indicates empty, the center dot half-
full and the right hand dot full.
OIL PRESSURE GAUGE-The oil pressure
gauge indicates the pressure in the engine's full
pressure lubrication system. The gauge is read

in the same manner as the fuel gauge with the dots indicating "0", "40"
and "80" respectively. The gauge shows the oil pump is working, but
does not indicate how much oil there is in the crankcase. At average
driving speeds the gauge should read approximately "40." When oil
gauge reads approximately "40" at average driving speed, it may
read near the "0" mark at hot idle. If indicator does not move above
zero at average driving speed or fluctuates greatly, you should check
the oil level immediately; and, if low, add oil to bring to the proper
level. (The oil level indicator reads "DO NOT OVER FILL," this
is important!) If the oil level is not low and fluctuation continues,
you should contact a Pontiac dealer immediately.
HEADLAMP AND INSTRUMENT PANEL LIGHT SWITCH-
The combination headlamp and instrument panel light switch is
located at the extreme left hand side of the instrument panel. When
the light switch knob is pulled out to the first position, the parking
lamps are turned on. When pulled to the second position the sealed
beam headlamps are turned on and the parking lamps off The instru
ment panel lights, tail lamps and license plate lamp are turned on in
both positions. In conjunction with the headlamp switch there is a
convenient foot switch located to the left of the brake pedal near the
edge of the floor mat. This switch enables you to lower the headlamp
beams when driving in the city or meeting approaching traffic in the
country. The "BRIGHT LIGHTS" red indicator light located in
the center of the speedometer face will be on when the upper beams
are on, and off when the lower beams are on.
INSTRUMENT PANEL LIGHTS—
As explained above, the instrument
panel lights come on when the light
switch control knob is pulled out. For
your convenience, turning the knob
clockwise decreases the brightness of
the instrument panel lights and counter
clockwise increases the brightness. When turned as far as possible in
a clockwise direction the lights will go off.
WINDSHIELD WIPER CONTROL KNOB-The windshield wiper
control knob is located to the right of the headlamp switch. Turning
the knob clockwise starts wiper; the amount that knob is turned
determines wiper speed. To operate windshield washer (ACCES
SORY) depress button in center of wiper control knob, hold button
depressed for a second or two then release.
IGNITION AND STARTER SWITCH—As a convenience to you
the ignition switch is illuminated when the combination headlamp
and instrument panel light switch control knob is pulled out. The igni-

tion switch has three positions, OFF when key is vertical, ON when
key is turned to right to first position, and START when key is turned
to full right position against stop. For instructions on starting Hydra-
Matic transmission equipped cars refer to page 11; for starting
Synchro-Mesh transmission equipped cars refer to page 15.
CANE HANDLE HAND BRAKE-The hand brake lever, generally
referred to as "Cane Handle", is located on the left hand side of the
steering column below the instrument
panel. Pull handle to apply the brake;
release with a counterclockwise twist.
Additional braking effort may be ob
tained by applying the foot brakes at the
same time the "Cane Handle" is pulled.
KEYS AND KEY NUMBERS-Two sets of keys are furnished with
your car. Each set contains a key with an octagonal handle and a key
with an oval handle. The octagonal key oper
ates the front door and ignition locks on all
models and the tail gate on station wagon
models. The oval key operates the glove com
partment lock on all models and the luggage
compartment lock on passenger car models.
To prevent unauthorized persons from securing duplications of your
keys, mark the key numbers, which appear on small metal slugs
fastened in the keys, in the space provided on page 4 of this manual
and on the Owner's Service Policy as soon as you take delivery of the
car, then knock out the slugs and destroy them. If you ever require
duplicate keys, they should be ordered from your local Pontiac dealer
rather than from the factory. In the event that you lose your keys and
key numbers, the proper numbers can be secured by wiring or writing
the Owner's Service Department, Pontiac Motor Division, Pontiac,
Michigan, giving the serial number of your car.
DOOR LOCKS—If you want to lock
the doors from the inside, push down
the small button on the window mould
ing of each door. Both front doors can
be locked from the outside with a key
in the usual way, but you don't have to
use the key to lock your car. Simply
open the door, press the button down
and then close the door while pushing the outside door handle plunger
in. When the door is closed, release the plunger, and the door is locked.

IMPORTANT: ALWAYS LOCK YOUR CAR WHENEVER YOU LEAVE IT UNATTENDED.
SAFETY FEATURE—On all 1955 model four-door sedans the rear door lock
is designed and set so that when the door locking button is depressed the
inside door handle is inoperative. This is a very important safety feature,
especially when children are riding in the car as it virtually eliminates the
chance of a child accidentally opening the door and falling from the car.
ASH TRAY—The ash tray may be re
moved by pulling the tray out against the
stop and depressing the stop spring at rear
of ash tray with thumb or finger. To
replace, merely place the ash tray in the
grooves provided and push into place.
VENTILATOR CONTROLS-Two control
knobs, located on the instrument panel below
the centrally located glove box door are used
to control the amount of outside air entering
the car through the two duct type ventilators
in the side kick pads. The amount that either
the left or right knob is pulled out will regu
late the amount of air entering the car from
that particular duct.
SEAT ADJUSTMENT-Seat adjustment
is made by pushing down the small lever on
the left side of the front seat and sliding
the seat back or forward to the position that
suits you best. On long trips, changing the
adjustment occasionally will be found help
ful in avoiding fatigue.
SUN VISORS-Folded up against the
top directly in front of the driver and
front passenger are two sun visors. The
visors may be slid toward the center of
the car (except for the Catalina and
Convertible styles), as well as swung around to either right or left to
protect your eyes when sun is at either side.
RATTLE-PROOF TOOL STORAGE-The
annoying rattles often caused by loose car
tools in the trunk, are eliminated by proper
use of the tool anti-rattle spring. When re
moving tools it is only necessary to remove the
connecting ring on the right side from the
hook on the floor.

HOOD LATCH—For your convenience
the hood latch and safety hook can be
completely released from the front of the
hood. To open the hood it is only necessary
to pull the release rod towards you to the
end of its travel. Near the end of its travel
the release rod will automatically disengage
the safety hook, which is provided to pre
vent opening of the hood should the latch
become accidentally unlatched.
FUSES—The headlight and parking lamp wiring system on your
Pontiac is protected from damage in case of short circuits by a thermo-
static circuit breaker mounted on the light control switch. During
short circuits the circuit breaker opens and closes intermittently,
thereby reducing the current load sufficiently to protect the wiring
from damage. This action will continue until the cause is eliminated
and is usually noticed due to a snapping sound at approximately 3 to
5 second intervals. If you are driving at night, the action of the
Thermo Circuit Breaker will be noticed by the headlamps burning
intermittently. When this happens, it is an indication of trouble
which should be corrected immediately.
The fuses that protect the main wiring and the
accessories are mounted in a fuse block on the
passenger side of the dash above and to the
left of the steering column. The fuse identifica
tion is printed on the fuse block which facilitates
location and replacement of a blown fuse.
All fuses on the fuse block are 7^ ampere with
the exception of the fuse marked Rheo Input
which is 4 ampere and protects the headlight
switch and instrument panel lights. A spare 73^ ampere fuse is located
in a clip at the bottom of the fuse block.
All accessories use a 7}/% ampere fuse with the exception of the electric
antenna, which has a 14 ampere fuse mounted in a line holder above
the fuse block, some electric clocks which have a \x/i ampere fuse
mounted on the back of the clock, and the air conditioning unit,
which has a 30 ampere fuse mounted in a line holder on the front of
dash above the steering gear. The cigar lighter has a special replace
able fuse attached to the rear of the lighter socket.
SEASHORE VS. DESERT—A driver whose car is subjected to
damp, salt air near the ocean might have to give more than average
attention to body and appearance services. On the other hand,
motorists driving in desert country have to contend with problems
of avoiding engine overheating and excessive wear from dust and
sand particles.
MAINTENANCE SCHEDULE
It would be impractical to prepare a schedule that would cover the
services required to maintain a car under all types of driving condi
tions. We, therefore, have prepared a schedule that gives our recom
mendations for the minimum services required when the car is being
driven under average driving conditions. The maintenance intervals
given should be reduced or increased according to the information
given in the sections on General Service, Chassis and Body Lubrica
tion, Engine Lubrication, and Tune-N-Test.

CRUISING SPEED—Services needed by your car will also depend
to some extent on the speeds at which you drive. The motorist who
habitually drives over 60 or 70 MPH on the open road will need
different service than one who cruises at 45 or 50 MPH.
USE OF LOW GEARS—At one time or another, you've ridden with
drivers who took a couple of blocks to get their cars into high after
starting. Low and second gears use far more gas than high gear. The
owner who drives in first only long enough to get started and shifts
into high at 20 to 25 MPH, saves on both gasoline and service expense.
HANDLING THE CAR—It's easy to see how varying skill in handling
a
car brings about different service needs. The car owner who bumps
into curbs or scrapes fenders when parking, naturally requires more
service than the motorist who drives carefully.
WARM-UP—Racing the motor or driving at high speeds before the
car is warmed up causes unnecessary wear, since the cold oil needs
time to circulate fully and efficiently between moving parts. It's a
good idea to let the engine run a moment after starting and to drive
at moderate speeds for at least ten minutes. This is particularly true
in cold weather.
DRIVING CONDITIONS
ROADS—The type of roads over which you drive can make a sur
prising difference in the service needs of your car. A car driven on
rough or stone-surfaced highways, for instance, will need tire replace
ment and steering and wheel adjustment more often than under
ordinary conditions.
CLIMATE—Owners living in hot climates may need to replace tires
somewhat sooner than those who live in the north, since heat is one
of the determining factors in tire life. Conversely, those living in
cooler areas may find they need more ignition, carburetor, and bat
tery service to maintain good gas mileage and quick, easy starting.
"LAY-OF-THE-LAND"—Lay-of-the-land (scientists call it "topog
raphy") also causes variations in service needs. Altitude and the num
ber of hills or mountains your car has to climb make a difference in
the up-keep required to keep it in good running order.
CITY VS. COUNTRY —It would be hard to say whether country or
city driving is "healthier" for your car. Open highways may lead to
engine wear from driving long distances at sustained high speeds,
while the restrictions and heavier traffic of city areas cause more stop-
and-go driving, with accompanying wear on such items as brakes
and tires.
[54]
Dual Kange
Mydra-Matic Drive
The Hydra-Matic drive consists of a fluid coupling, which replaces
the conventional clutch, combined with a hydraulically controlled
automatic transmission having four speeds forward and one reverse.
Gear changing is accomplished automatically by the transmission in
accordance with the performance demands of the road conditions
encountered and the wishes of the driver.
HOW TO OPERATE THE DUAL RANGE HYDRA-MATIC
DRIVE—The Hydra-Matic drive is convenient to operate in that the
driver only selects, by use of the control lever and indicator segment,
the speed range in which he wishes the car to operate. The speed
ranges are clearly shown on the indicator segment, and are illuminated
when the instrument panel lights are turned on. The speed ranges are
designated as follows:
N—Neutral and starting
ADR—For all normal forward driving and improved fuel economy.
DRA—For faster acceleration and driving in congested traffic.
LO—For controlled power.
R—Reverse and parking
TO START ENGINE-Place Hydra-
Matic control lever in N (neutral) position.
The starting circuit is wired so that
the starter will not operate unless the
lever is in neutral; press accelerator pedal
to toeboard once and release, this allows the
automatic choke to close and position throttle as determined by the
"starting" step of the fast idle cam; turn the ignition switch key to
the right to the full stop position, release as soon as engine starts. As
soon as engine is running open accelerator slightly and then release
to position throttle as determined by the "running" steps of the fast
idle cam.
Should the engine fail to start in five to ten seconds, it is possible that
it is flooded. In that case, press the accelerator pedal slowly to the
floor and hold it there when starting. This renders the choke inoper
ative and relieves the flooded condition.
NOTES: When starting at temperature below 0° F. it may be necessary
to hold accelerator pedal down slightly to open throttle more than provided
by the "starting" step of, the cam.
When starting a warm or hot engine, hold accelerator pedal down half way.
[HI

CAUTION: Do not "pump" the accelerator pedal at any time. Avoid racing
the engine during warm-up period.
Cold Weather—In cold weather (0° F. and colder) the engine must
idle with the control lever in the N position until engine and trans
mission are warmed up. When engine is cold and running at fast
idle, the car will tend to creep when the control lever is moved to a
driving position. A slight application of the foot brake or hand brake
will hold the car until motion is desired.
OPERATING IN DR RANGE—DR range has two driving positions,
each marked by an arrow. The control lever can be moved at will
from one arrow position to the other when traveling at any car speed
on dry roads where traction is good.
The left hand arrow position in DR range
is provided for all normal forward driving;
it reduces engine speed, provides better
driving comfort and improves fuel econ
omy. When driving in this range at a car
speed of less than 60 MPH extra perform
ance can be obtained by depressing the accelerator pedal. This will
cause the transmission to shift down into third speed. The car speed
determines the amount the accelerator pedal must be depressed to
cause this shift. At a speed of about 27 MPH or less the accelerator
pedal need only be partially depressed to cause the shift and at speeds
of 28 MPH to 60 MPH it is necessary to completely depress the
pedal. The transmission will automatically return to fourth speed as
car speed increases or the accelerator pedal is released.
The right hand arrow position in DR range
is provided for better acceleration and is
very useful when driving m congested traffic.
It is also effective when ascending or de
scending long mountain grades. When driv
ing in either DR range at a car speed of less
than 20 MPH an extra burst of speed can be obtained by completely
depressing the accelerator pedal. This will cause the transmission to
shift down to second speed. The transmission will automatically
return to third or fourth speed, depending on the DR range being
used, as the car speed increases or pedal is released.
Acceleration in DR Range—The shift events from first speed to
second, second speed to third, and third speed to fourth (direct drive)
will occur at progressively higher car speeds depending on the amount
the accelerator pedal is depressed.

Service Needs of your Poutiac
The maintenance services that your 1955 Pontiac may require are
largely dependent on your driving habits plus the road and climatic
conditions in which the car is driven.
By learning the type of driving you do, your Pontiac dealer's service
manager or service salesman will be better qualified than any one else
to recommend what services your car may need. Your Pontiac dealer's
mechanics have everything at their disposal to do the best work at the
least possible cost. They have a specialized knowledge of the Pontiac
car, are supplied with information on latest service methods, and use
specifically designed equipment where needed.
With few exceptions, the best way to determine what your car needs
is through your own observation of the way it operates, plus visual
inspection or testing by mechanics trained on-Pontiac diagnosis.
DRIVING HABITS
STARTING AND STOPPING—The driver who beats everyone
away from traffic lights and stops by jamming on the brakes at the
last minute has to pay for his fun. Rapid starts and stops waste gas
and oil and place undue wear on even the best engine parts, brakes,
and tires.

Caution Against Coasting in Neutral—Do not coast with the
control lever in the N (neutral) position. It is unlawful in some
states and sometimes is harmful to the transmission.
Stopping the Car—Leave the control lever in the driving position
selected and release the accelerator pedal. The engine is then left "in
gear" and helps to slow down the car. For further stopping effort apply
the brakes in the conventional manner.
CAUTION: When the driver leaves the car, with the engine running, the
control lever should always be in the N (neutral) position. This precaution
prevents movement of the car, should the accelerator pedal be accidentally
depressed by a passenger. For additional safety, apply parking brake when
opening garage doors, etc.
OPERATING IN LO RANGE-The con
trol lever must be raised to move from DR
range to LO range. The LO range (second
speed) is provided for pulling through deep
sand or snow and ascending or descending
steep grades where traffic signs call for
placing the transmission in first or second gears (keep below 40 MPH
to avoid a 2-4 upshift). It is also best for getting the car in motion
on icy roads.
When driving in LO or either DR range at a car speed of less than 10
MPH an extra burst of speed can be obtained by completely depress
ing the accelerator pedal. This will cause the transmission to shift
down to first speed. The transmission will automatically return to
second, third or fourth speed, depending on the range being used, as
car speed increases or pedal is released.
The control lever can be moved from either DR position to LO at any
car speed below 50 MPH on dry roads where traction is good.
CAUTION: Do not shift into LO range on slippery roads as a skid may
be induced. Slippery roads demand judicious use of the brakes to reduce
car speed.
REVERSE—To engage reverse, simply
raise the control lever and move it to the
R position. Moving lever between LO and
R while applying light accelerator pedal
pressure permits rocking the car when re
quired to get out of deep snow, mud or
sand. Avoid engaging reverse at speeds
above 5 MPH.
NOTE: Control lever will stop at left DR position when moved from reverse
towards neutral with lever raised. This prevents unwanted "over-selecting"
into neutral.
13

PARKING—For additional safety when parking, turn off ignition
key and move selector lever to R position. When parking on an incline,
hold car with foot brake a few seconds to permit engagement of
transmission parts.
TO START ENGINE BY PUSHING CAR—If it is necessary to
start the engine by pushing the car for a short distance due to a low
battery, move control lever to N position. When a speed of approxi
mately 25 MPH is attained, turn ignition switch on and move control
lever to either DR position.
TOWING THE GAR—Disconnect the propeller shaft at the rear
universal joint and remove from the car by sliding the front universal
joint and shaft assembly backwards, or raise the rear wheels off the
ground to prevent possible damage to the transmission.
When towing the car with the propeller shaft disconnected, the tow
car operator should be cautioned to make certain that oil does not
leak from the rear bearing retainer.
HYDRA-MATIG FLUID—Refer to page 30 for information on
fluid recommendations, change intervals, and level checking.

Wiring Diagrams
We don't like to burden you with technical details, but so many owners
have requested wiring diagrams that we have included them for those
who are interested in knowing more about the intricate "nervous
system" which makes up the electrical system in your Pontiac.
These diagrams are schematic. That means that they are arranged so
that you can see which wires inter-connect each switch, lamp, etc. In a
schematic diagram the wires are shown separately, while on the car
some are enclosed in looms. The legend on the diagrams refer to the
color of the wires which should be connected to each terminal.

CARE OF THE CONVERTIBLE BACK WINDOW
The back curtain on the Convertible Coupe is provided with pliable
plastic window which is of large size to allow ample visibility at the
rear of the Convertible Top. The plastic material at this location
makes possible a larger window than can be utilized if glass were
used. Due to the texture of the plastic window, it is susceptible to
scratches and abrasions; caution must be used in its cleaning and care.
1. When removing road dust, use a soft cotton cloth moistened with
water and wipe cross-wise of the window.
2. To clean the back window, use cold or tepid (not hot) water and
a mild, neutral soap suds. After washing, rinse with clear water
and wipe with a slightly moistened clean soft cloth.
CAUTION: Never use solvents such as alcohol or volatile cleaning agents
on the plastic window. These liquids may have a deteriorating effect on
the plastic and, if spilled, may spot the painted finish on the rear body
panels directly below the rear window.
3. In removing frost, snow, or ice from the plastic back window
DO NOT USE A SCRAPER. In an emergency, warm water may
be used. Use care that this warm water does not contact the
actual glass windows or windshield.
CARPET FLOOR COVERINGS
Carpets are either cemented or tacked down securely in place and
should not be removed unless it is definitely necessary to do so. If
the carpet must be removed, it should not be forcibly pulled loose;
this may cause the nap to pull through the warp of the carpet and
ruin its appearance. A corner of the carpet should be turned back,
and a wide-bladed putty knife or similar tool should be used to
separate the carpet from its cemented foundation.
To clean these floor coverings, first, brush thoroughly. If soil remains,
use a volatile type cleaner. Repeat for heavily embedded stains.
Extreme care should be taken to make certain that carpets are not
"soaked" with the cleaner. This may cause deterioration of the rubber
compound used in the backing construction of some carpets.
NOTE: Neutral soap and water may also be used, but at the risk of color
removal.
Make certain that carpets are thoroughly dry before closing all
windows and door openings to prevent possible mildewing of the
carpet.

STARTING THE ENGINE
Depress clutch pedal to floor; this relieves the starter of the task of
turning the transmission gears (an important advantage in cold
weather starting). (If clutch pedal is not depressed, gearshift control
lever must be placed in neutral position to prevent accidental move
ment of car while starting.) Press accelerator pedal to toeboard once
and release, this allows the automatic choke to close and position

NOTES: When starting at temperature below 0° F. it may be necessary
to hold accelerator pedal down slightly to open throttle more than provided
by the "starting" step of the cam.
When starting a warm or hot engine, hold accelerator pedal down half way.
Cold Weather—In cold weather (0° F. and colder) the engine must
idle with the gearshift lever in neutral and parking brakes pulled on
or foot brakes applied until engine and transmission are warmed up.
CLUTCH
PROLONGING CLUTCH LIFE-The clutch in your Pontiac will
not require much attention due to the use of clutch throwout ball
bearing which is lubricated for life at the factory. However, normal
wear in the clutch facings will result in a gradual change in the
"pedal lash".
Excessive wear may be caused by "riding" the clutch, the habit some
drivers have of resting the left foot on the clutch, thus keeping the
releasing parts in contact but not disengaging. Excessive wear can
also be caused by rough usage. Letting the clutch up "with a bang"
is not only hard on the clutch itself but also on tires and the entire
car. Another practice which puts needless wear on the clutch is
"holding" your car on a hill by partially engaging the clutch instead
of using the brake.
CLUTCH PEDAL ADJUSTMENT-The
clutch pedal should be adjusted from time
to time so that it has some free travel
before the clutch actually begins to dis
engage. The pressure of one finger should
be enough to push the pedal in about an inch before the resistance of
the clutch spring is felt. If there is little or no "pedal lash" the clutch
may be slipping, which will cause it to wear out faster. If there is too
much "pedal lash", the clutch may not disengage completely and
cause gear shifting trouble. When "pedal lash" is less than % inch
or more than \}/g inches, an adjustment should be made.
[16]
The best cuts of leather have certain scars, horn marks, and briar
scratches. These likewise do not detract from quality or durability
but indicate that the hide carrying these "blemishes" is of the top
cut grade with entirely natural markings.
If dirt accumulates on the surface, this develops into a hard grit which
under pressure will cut the finish and cause the leather to crack or
bleed color. Whenever dirt accumulates, the surface should be cleaned
occasionally as follows:
1. Apply a thick suds of lukewarm water and a neutral soap worked
up on a piece of gauze or cheesecloth to the surface.
2. Wipe entire surface using only a damp cloth.
3. Wipe leather dry with a soft cloth.
Imitation Leathers — Imitation leather fabrics are used for auxiliary
trimming in conjunction with both fabric and genuine leather up
holsteries.
Recommended cleaning instructions for imitation leather are the
same as outlined for genuine leather and as in the case of genuine
leather one of the most important factors is the removal of soilage
as quickly as possible after it occurs.
NOTE: Polishes and cleaners used for auto body finishes, volatile and other
clear cleaners, naphtha, furniture polishes, oils, varnishes, or household
cleansing and bleaching agents should never be used, as they may perma
nently damage the surface finish of either the genuine or imitation leather
and mar the beauty of the car interior.
Convertible Top Materials—Generally, soilage can be removed
with art gum or crude rubber. If dirt is heavily embedded in the
fabric, the top should be thoroughly brushed with a whisk broom.
In this, brushing a minimum of pressure should be applied to those
areas of the assembly which cover the metal bows of the top struc
ture; heavy abrasion will disturb the surface of the material appre
ciably, causing an unsightly appearance. After brushing, the top
should be washed thoroughly with a neutral soap suds and lukewarm
water using a cloth or brush with soft bristles. Generous quantities
of clear water should then be applied over the surface to remove any
traces of soap which might remain. Never use volatile or other clear
cleaners.
After being wet by cleaning or by rain, the top should be allowed to
dry out thoroughly before being collapsed; the dampness may cause
mildew and wrinkles.
[49]

rial. (2) Nature and age of the stain. (3) Effect of stain-removing
agents on the color, structure, and general appearance of the fabric.
For best results, stains should be removed from upholstery as soon as
possible after they have been made. If they are allowed to stand for
some time, they very often become set, and removal becomes more
difficult—frequently impossible.
TRIM DESCRIPTION AND CLEANING METHODS
Fabrics—Soap and water may be used in cleaning fabrics. A neutral,
nonalkaline soap should be used with lukewarm water. The suds
should be frothy, not watery. Suds only should be applied in moderate
quantities with a damp cloth, sponge, or soft brush and rubbed
gently. Soap suds should be removed with a clean, damp cloth or
sponge. Then the surface should be wiped several times with a dry
cloth. While still damp it should be brushed lightly with a whisk broom
or medium stiff brush. Permit air to circulate freely over the wet
upholstery.
In some cases of especially stubborn stains it may be necessary to use
either GM Upholstery Cleaner or GM Upholstery Spotter available
from your Pontiac dealer. Use as the label directs.
NOTE: The following safety precautions should be observed in cleaning
fabrics:
1. Do not use as a cleaning solvent any gasoline which is colored or which
contains tetraethyl lead.
2. Do not use as a cleaning solvent, acetone, lacquer thinners, enamel
reducers, nail polish remover, etc.
3. Do not use laundry soaps or bleaches and reducing agents, such as the
following: Chloride of lime, Javelle water, Hydrogen peroxide, Sodium
hydrosulphite, Potassium permanganate, Chlorine or chlorine water,
Sulphurous acid (sulphur dioxide), Sodium thiosulphate (Photographers'
hypo). The use of these agents tends to weaken fabric and to change
its color.
4. Do not use too much cleaning fluid; some interior trim assemblies are
padded with rubber, and volatile cleaners are generally solvents for
rubber. The application of too much cleaner may destroy these rub
ber pads.
Genuine Leathers—Custom four-door sedans and Custom Catalinas
use genuine leather trim in some areas.
Genuine leathers have a natural tendency to wrinkle. Such wrinkles
or creases occurring in service do not detract from the wearing qualities
of the leather. A cushion in this condition is simply described as
having "comfort wrinkles".
[48 1
Weather Comfort
Control
VENTILATION SYSTEM-The ventilating panes in the door
windows, the duct type ventilators and the underseat heater are all
part of a controlled ventilation system.
Vent Panes—The ventilating panes
can be adjusted, by means of a crank
control, to any position to suit weather
conditions and provide circulation of
outside air in the car. They are also
useful in preventing fogging of the
windows, especially the windshield, in
cold weather.
Vent Ducts—Two "VENT" control knobs,
located on the instrument panel below the
centrally located glove box door are used to
control the amount of outside air entering
the car through the duct type ventilators in
the side kick pads. The amount that either
the right or left knob is pulled out will
regulate the amount of air entering the car from that particular duct.
The ducts are equipped with screens to prevent insects from entering
the car.
HEATER AND DEFROSTER-Even distribution of heated air is
accomplished through the use of a heater distribution manifold
running crosswise of the body under the front seat. Hood high air is
taken in through the intake directly below the windshield, heated
and discharged through the manifold toward the front and rear of the
car for equalized distribution by openings in the manifold under the
driver and front seat passenger.
Temperature Control—The "TEMP" control (lever on left of
steering column) is a thermostatic control similar in operation to the
thermostatic controls found on automatic oil or gas hot air furnaces.
To maintain the desired temperature inside the car the "TEMP"
control automatically regulates the flow of hot water to the heater.
This makes it unnecessary to change the setting of the "TEMP" lever
[17]
