IMPORTANT FACTS YOU SHOULD KNOW ABOUT GASOLINE MILEAGE AND HOW TO IMPROVE IT
How you drive, where you drive, and when you drive all have an effect on
how many miles you can get from a gallon of gasoline. The careful attention
you give your car as far as maintenance and repairs are concerned will also
contribute importantly to fuel economy.
83. Unleaded gasoline is essential for proper emission control system
operation, and it will minimize spark plug fouling. The use of leaded
gasoline can severely reduce the effectiveness of the emission control
system and result in loss of warranty coverage.
Fuel Selection
Your vehicle is designed to operate only on unleaded gasoline of at least 91
Research Octane. The gasoline should also have a Motor Octane of at least
FIG. 1-1: UNLEADED FUEL OCTANE IDENTIFICATION
If the service station gasoline pump has a symbol similar to that in Fig. 1 -1,
use unleaded gasoline with a symbol number of 2. If the pump has a label
indicating gasoline octane in terms of the average of Research and Motor
Octane [ ] as shown in Fig. 1 -1, use unleaded gasoline with a number
of at least 87.
"lackrabbit" Starts
Gasoline can be conserved (and engine and tire life prolonged) by avoiding
unnecessarily rapid acceleration away from lights and stop signs.
Stop-And-Start Driving
Frequent stops and starts during a trip really cut down on your miles per
gallon. Plan even your short shopping trips to take advantage of through
streets to avoid traffic lights. Pace your driving like the professional drivers
to avoid unnecessary stops.

IMPORTANT FACTS YOU SHOULD KNOW ABOUT GASOLINE MILEAGE AND HOW TO IMPROVE IT
Excessive Idling
An idling engine uses gasoline, too. If you're faced with more than a few
minutes wait and you're not in traffic, it may be better to "turn off” and start
again later.
Sudden Stops
Sudden stops themselves don't waste gasoline, but energy is wasted as heat
in braking. Energy in the form of gasoline is also needed to accelerate back
to driving speed.
Lubricants
A properly lubricated vehicle means less friction between moving parts.
Consult this manual and the maintenance schedule for the proper lubricants
to use and the lubrication intervals.
Air Cleaner
Your car receives its power from a mixture of gasoline and air. The air is
taken into the system through the air cleaner so it's important to replace
the air cleaner at required intervals. A dirty air cleaner reduces engine
efficiency.
Properly Tuned Engine
Overall tuning (a check on timing, spark plugs, emission control device,
etc.) can improve your car's gas mileage. You just can't expect an "out-of¬
tune" engine to give you good gas mileage and cleaner air.
Excess Weight
Fuel economy is related to the work the engine must do. The heavier the
load, the more power it takes. Keep excess weight to a minimum by
removing any personal effects or luggage from the car or trunk when they
are not needed.
Tire Inflation
Under inflation not only causes needless wear of the tires, but can also
waste gasoline. It's a good idea to check tire pressures regularly.
Wheel Alignment
Incorrect "toe in" or "toe out" has the effect of dragging your front tires
sideways and causes premature tire wear. It takes power to carry this extra
load and that takes gas from your tank.

Instructions and suggestions on proper op¬
eration and care are contained in this Owner's
Manual. Please refer to it as frequently as
needed to help maintain the performance of
your Cacfillac.
For convenient Owner's Manual storage,
use the special pocket in the left hand side of
the glove compartment door. The vinyl case is
a convenient container for the other booklets,
folders, and papers that pertain to your Cadil¬
lac.
Driver Checklist
BEFORE DRIVING OFF
1. Lock all doors.
2. Position seat and adjust head restraints.
3. Adjust inside and outside mirrors.
4. Fasten belt restraints.
5. Check that "GENERATOR'' and "STOP
ENGINE OIL PRESSURE" warning bulbs
light when key is turned to start position.
6. Be sure you understand your car and
how to operate it safely.
Keys
BEFORE ENTERING CAR
1. See that windows, mirrors and lights are
clean.
2. Visually note inflation condition of tires.
3. Check that area to rear is clear if about to
back up.
Two or more separate keys. Fig. 1-2, are
provided for your car. Each key has a different
cross section so that it can be inserted only in
certain locks.
• KEY WITH SQUARE HEAD (STAMPED
"A") — for ignition switch only.
• KEY WITH OVAL HEAD (STAMPED "B")
— for door locks, glove compartment
and trunk locks.
• KEY WITH NOTCHED OVAL HEAD
(STAMPED "B") — for console lock on
Talisman models; or right rear door lock
on Fleetwood Seventy-Five Limousines.
The code number of each key is stamped on
the "knock out" plug in the key head. Your
Cadillac Dealer removed these plugs and
placed them with the spare set of keys in the
sprecial key envelope that was given to you at
time of delivery.
FIG. 1-2: 1975 CADILLAC KEYS

For Your protection:
• Record the numbers on the key envelope
and discard the key plugs.
• Keep the key envelope in a safe place
such as your wallet, NOT IN THE CAR.
In the event the original keys are lost, dupli¬
cates can be made by your dealer or a lock¬
smith using the key code information.
Glove Compartment
BE SURE TO LOCK THE GLOVE COM¬
PARTMENT OR CONSOLE COMPARTMENT
AND REMOVE THE KEY FROM THE CAR
WHENEVER IT IS NECESSARY TO LEAVE THE
IGNITION KEY WITH AN ATTENDANT.
• To unlock: insert oval head key and ro¬
tate one-quarter turn clockwise to the un¬
locked position. An additional quarter
turn opens the door.
• To lock: insert key and rotate fully
counter-clockwise.
• Key may be removed in either locked or
unlocked position.
Front Console
Talisman models are equipped with a con¬
sole for the front seat passengers, Fig. 1 -3. The
console lock is operated by the notched oval
head key.
FIG. 1-3: CONSOLE LOCK
Door Locks
To lock any car door from the outside, de¬
press the interior door lock button and close
door. The outside door handle button does not
need to be depressed to lock the door.
The front doors may be locked and un¬
locked with the oval head key. Lock doors
from inside by depressing the interior door
lock button. Unlock by raising the button.
• When the door is locked, movement of
the inside door handle does not unlock or
open the door. Door must be unlocked
before it may be opened. Avoid pushing
on door glass when opening or closing
doors.
REMINDER: Always lock the doors when
driving for greater security in the event of an
accident, to help keep children from opening
door, and for greater security against entry by
unwelcome persons while momentarily stop¬
ped.
On ELDORADO styles, an interior door
handle is provided near the rear of the right
door armrest for the convenience of rear seat
passengers.
On the FLEETWOOD SEVENTY-FIVE
LIMOUSINE style, a separate oval head key is
provided for the lock on the right hand rear
door. This key is coded specifically for that
door and the head is notched for identifica¬
tion.
Illuminated Entry System
On cars equipped with the Illuminated
Entry System, a light above each exterior door
lock, and the inside courtesy lights are turned
on for approximately 20 seconds by pressing
the outside front door handle button, Fig. 1-4. i— ■
Holding the button in will not cause the lamps 1 ^ I

damaged by attempted forced entry.
C. The alarm blows the horn intermittently
and flashes all exterior lights (except
high beams) for approximately three to
seven minutes, then shuts down au¬
tomatically to conserve the battery.
D. If the hood, trunk lock, or a door is dis¬
turbed again, the system repeats the
alarm.
E. The trunk may be opened using the key
without activating the alarm or disarm¬
ing the system.
A. If a passenger remains in the car, the
passenger should lock the door after
closing it (or use the manual lock but¬
ton) to prevent arming the system. This
permits the passenger to open the door
without activating the alarm.
B. When re-entering, if the alarm is armed
but a window happens to be open, re¬
member to unlock the door with the
key because pulling the lock knob up or
operating the power lock switch will
not disarm the system.
C. If you decide to disarm the system after
pressing the power door lock switch to
"LOCK” (before closing the door) press
the lock switch to the unlock position.
D. L ocking the doors manually by using
the key or inside lock knobs will not
arm the system.
Luggage Compartment
The lid on the luggage compartment is
counterbalanced for easy opening and has a
key-lock release.
To open the lid:
• Rotate the Cadillac crest covering the
lock cylinder counterclockwise until it
latches.
• Insert the oval head key.
• Turn the key in a clockwise direction to
release the lid.
An interior light illuminates the luggage
compartment when the lid is raised. To close
and lock the trunk lid:
• Remove the key which allows the crest to
spring back to its normal, closed position.
• Pull the lid down to a position six or eight
inches from closing.
• Push the lid down firmly.
FIG. 1-7: REMOTE CONTROL TRUNK RELEASE
Remote Control Trunk
Lock
The remote control lock (on cars so equip¬
ped) permits unlocking and raising the trunk
lid from inside the car. Fig. 1-7.
• To open trunk, press and momentarily
hold the release button located thside
glove box door opening at left (glove^aox
door below dash in Air Cushion Restraint
System equipped cars). A "TRU^JK
OPEN" warning light on the upper in¬
strument panel glows with the trunk open
and ignition in RUN position. The trunk
lid also unlocks in the conventional
manner using the oval head key.

• To close trunk, lower lid and push it
down until latched - DO NOT SLAM. The
pull-down and latch mechanism pulls
the lid fully down.
• Keep glove compartment locked when
leaving car unattended to prevent un¬
wanted entry into the trunk.
An automatic trunk lid release without the
pull-down feature and warning light, is avail¬
able as a dealer-installed accessory.

• Release the lever to lock the seat in this
position.
The seat back also tilts forward or rear¬
ward slightly when the seat is moved.
FIG. 1-9: SIX-WAY SEAT CONTROL

FIG. 1-10: SEAT-BACK RECLINER CONTROL
The seat can be operated as follows:
■ The front control provides up and down
movement of the front of the seat.
• The center control provides forward and
backward movement, and up and down
movement of the entire front seat.
• The rear control provides up and down
movement of the rear of the seat.
RECLINING PASSENGER FRONT SEAT-
BACK
The passenger's reclining seat-back, on
models so equipped, can be reclined rearward
approximately 20 degrees from normal posi¬
tion by lifting the control lever at the outboard
side of the passengers seat cushion and exert¬
ing rearward pressure, Fig. 1-10. Lifting the
lever with no pressure on the seat-back allows
the seat-back to return forward.
Rear Seat Filler Panel
j CAUTION: The filler panel between thel
rear seat and the rear window should not I
be used for storage—even of light weight, j
| small articles. They might become:
dangerous projectiles during an accident. |
Large items may also reduce vision to the .
J^rear.
Coat Hooks
All Cadillacs, except convertible and
Seventy-Five styles, are equipped with two
coat hooks, one on each inside roof rail.
REMINDER: Avoid hanging objects on the
right hand coat hook in such a way that you
block the driver's vision to the right rear quar¬
ter.
Power Windows
Power windows can be operated only when
the ignition switch is in the RUN position.
REMINDER: Remove the ignition key when
the vehicle is not attended by a responsible
person.
The power window master control. Fig. 1-5,
is located on the left front door armrest. The
control switches are positioned to correspond
with the windows they control—the left front
switch for the left front door window, etc.
Individual switches are provided under each
window for passenger use.
Controls for both rear door windows on the
Fleetwood Seventy-Five Sedan and Limousine
styles are located on the side trim panel above
each rear armrest, Fig. 1-11.
On the Limousine style, the driver's master
control switches for the rear door windows
operate only to close the windows.
The window lock-out switch at the window
master control has two positions:
• "NORMAL": all windows may be oper¬
ated by the master controls or the indi¬
vidual window switches (ignition switch
in RUN position).
• "LOCK": windows may be operated by i—i
the master controls, but the individual 1 9 I

switches are inoperative (ignition switch
in RUN position).
Limousine Partition Glass—Individual con¬
trols are mounted with the rear door window
switches, Fig. 1-11. These switches remain
operative when the window lock-out switch is
in the "LOCK" position.
Rear View Mirrors
INSIDE REAR VIEW MIRROR
To raise or lower mirror to achieve desired
field of view, grasp mirror and exert sufficient
pressure by pushing or pulling up, down, or
sideways. Fig. 1-12:

glare from following headlights.
FIG. 1-12: INSIDE REAR VIEW MIRROR
REMOTE CONTROL OUTSIDE REAR VIEW
MIRROR
Your Cadillac is equipped with a remote-
control outside rear view mirror on the driver's
side of the car. Movement of the control knob
inside the car, on the left front door armrest,
allows you to adjust the mirror to suit your
requirements. Fig. 1-13.
The remote control for the right-hand out¬
side rear view mirror (if your car is so equip¬
ped) is located below the instrument panel
center air outlet, to the right of the speedome¬
ter.
Move the control knob with the thumb (as
FIG. 1-13: OUTSIDE MIRROR REMOTE
CONTROLS
shown) or fingers to adjust the right-hand mir¬
ror.
NOTE: Scraping ice from the mirror face
could cause permanent damage. For removal
of ice, use a de-icer (spray type, blower type,
etc.).
Head Restraints
• Head restraints are designed to help re¬
duce injuries due to "whiplash."

FIG. 1-14: HEAD RESTRAINT LATCH
• Select one of the two positions—up or
down—that places the top of the head
restraint closest to the top of your ears.
• Do not use head restraint above the up
detent position.
• Head restraint can be raised by pulling up
until you feel it click into the "detent”
position.
• To lower; release latch at base of support¬
ing rod and push down on restraint, Fig.
1-14.
• Do not operate vehicle with head re¬
straints removed, since occupants lose
the protection they provide.
Air Cushion Restraint
System
If your vehicle is equipped with the optional
Air Cushion Restraint System consult the Sup¬
plement to the 1975 Cadillac Owner's Manual
for information on ACRS function, operation
of the readiness indicator light, maintenance
requirements, and for information on child
restraint in ACRS-equipped cars.
Use of lap belts, or optional shoulder belts,
is covered in this manual.
Belt Restraint System
This vehicle is equipped with a belt system,
starter interlock, and a light-buzzer reminder
system which is designed to prevent starting
the car until outboard front seat occupants are
buckled in. Vehicles equipped with the Air
Cushion Restraint System do not have a starter
interlock or a light-buzzer reminder system.
NOTE: All 1975 model General Motors pas¬
senger cars sold in CANADA and all U.S.
models produced after the U.S. Belt Re¬
straint System Regulation was modified in
Oct. 1974 have a light-buzzer reminder sys¬
tem which reminds occupants when the
driver's and any front passenger's belt re¬
straints are not fastened. Operation of this
“BELT RESTRAINT BUZZER/LIGHT REMIN¬
DER" is explained under that heading on
page 14 in this manual. However, these cars
do NOT have a starter interlock system — a
system which prevents starting the car until
the driver and the right front passenger are
buckled up. Therefore, the information
about the starter interlock system under the
heading "TO START CAR" in this manual
does not apply, nor do any other references
to the starter interlock system in this manual
or other printed materials apply.
TO START CAR
• Belt restraints must be properly buckled
around each outboard front seat occup¬
ant after being seated before the starter
will operate.
• The reminder buzzer and light are de¬
signed to go on if belt restraints are un¬
buckled at occupied front seats while the
vehicle is underway (the engine will con¬
tinue to run).
• The engine may be restarted after a stall
without interlock interference if the
driver remains seated.

IF STARTER WILL NOT OPERATE
• Remove any objects from unoccupied
front seats.
• Re-buckle front belt restraints.
NOTE: Front seating positions contain a
weight detector which is designed to activate
the starter interlock or the buzzer and light
reminder whenever weight is placed on the
seat and belts are not buckled. The weight
detector cannot distinguish between a pas¬
senger and any object on the seat, therefore,
such items should be stowed elsewhere in the
vehicle.
It is necessary that the weight detectors be
activated at all times. This requires a small but
continuous current from the battery which
under normal circumstances will not result in
a discharged battery. However, leaving an ob¬
ject on the front seat or leaving the front belt
restraints fastened while the car is parked
creates a heavier current drain which could
result in a discharged battery after a period of
time, which will vary depending on battery
and weather conditions.
IF STARTER STILL WILL NOT OPERATE
• Set parking brake firmly, move transmis¬
sion lever to "PARK."
FIG. 1-15 BELT INTERLOCK
OVERRIDE BUTTON
FIG. 1-16 LAP-SHOULDER BELT
• TURN IGNITION KEY TO "ON"
("RUN").
• Open hood and press button on manual
override switch labeled "START",
mounted on bright orange support at rear
of engine compartment on driver's side,
Fig. 1-15.
• Close hood, enter car, fasten belt restraint
and follow normal starting procedures.
NOTE: The reminder buzzer and light are
also designed to come on if a problem de¬
velops in the starter interlock system. If the
car will not start and the buzzer/light remin¬
der did not come on, the problem is not likely
to be due to the starter interlock system. If the
starter will crank, this indicates the interlock
is not causing the problem.
LAP-SHOULDER BELT COMBINATION
• Adjust front seat to satisfaction of driver
and sit erect and well back in seat, Fig.
1-16.
• In a single motion, pull the lap-shoulder
belt webbing across lap far enough to
permit inserting metal latch plate end of
belt into the buckle, until a snap is heard.
If webbi ng is not pul led out far enough to
reach buckle, let lap belt rewind into its

retractor to release lock mechanism, so
belt can be pulled out to the proper
length.
• Position "lap" portion of belt across lap
as LOW ON HIPS as possible. To reduce
the risk of sliding under belt during an
accident, adjust to a SNUG FIT by pulling
belt firmly across lap in direction of lap
belt retractor so it can take up slack. The
belt retractors are designed to automati¬
cally take up excess webbing. Fig. 1-17.
^CAUTION: A snug fit and a low lap belli
| position are essential to lessen the chance |
of injury in the event of an accident be-|
cause this spreads the force exerted by the I
lap belt in a collision over the strong hip I
bone structure rather than across the soft!
| abdominal area. To help lessen the chance |
of injury in the event of an accident: never |
use the same belt for more than one per-'
son at a time; avoid wearing belts in a |
twisted condition; and do not allow belts |
| or hardware to become pinched between l
the seat structural (metallic) members or j
in the door.

Belt restraint buckles are located close to
the seat to provide shoulder belt attaching

points that reduce the tendency of shoulder
belts to pull the lap belt upward into the soft
abdominal area in the event of frontal impact.
• The front seat shoulder belts in this vehi¬
cle are equipped with a "vehicle sensi¬
tive retractor" which is designed to grip
the belt only during a sudden stop or
impact. At other times it is designed to
move freely with the occupant.
• For best restraint the slight tension on the
shoulder caused by the shoulder belt re¬
tractor is desirable.
• A comfort clip is provided for those who
find the shoulder belt tension a source of
FIG. 1-18: SHOULDER BELT COMFORT CLIP
discomfort. If the shoulder belt tension-
becomes uncomfortable, pull down on
the shoulder belt to provide the least
amount of slack necessary to relieve ten¬
sion (not more than one inch) then push
the comfort clip snugly against the guide
loop. Fig. 1-18.
| - — - “ \
j CAUTION: Excessive slack could result in |
| increased personal injury due to reduced *
| restraint system effectiveness.
• To unfasten belts, depress push button in
center of buckle.

the retractor. The bulk of the twisted belt may
cause the retractor to jam so it will not rewind
further, while at the same time the retractor
locking mechanism may prevent the belt
from being withdrawn. To release a jammed
belt, open the cover on the rear of the retrac¬
tor and rotate the key slot while pulling the
belt upward. Fig. 1-19. This should allow the
belt to be untwisted. If for some reason the
lap belt portion remains jammed, or other
parts of the restraint system do not operate
properly, take the vehicle to your dealer for
service.
• When no longer in use, front seat lap-
shoulder belts can be stowed by allowing
them to rewind into their retractors. The
comfort clip can be adjusted when re¬
moving belts, so shoulder belt slack will
be fully taken up by retractor.
I CAUTION: Do not wear shoulder belt!

| event of an acc : dent.
NOTE: Take care not to let the “lap" portion
of the belt twist while it is being rewound into
BELT RESTRAINT BUZZER/LIGHT
REMINDER
• The front belt restraints are linked to a
buzzer and light which remind occu¬
pants to fasten their belts.
• The buzzer and light are designed to
come on when any outboard front seat
occupant's belt is not fastened, while at¬
tempting to start the engine, or if any front
belt is unfastened while driving in any
forward gear.
• The reminders do not come on when the
engine is running and a front belt is un¬
buckled if the transmission is in Park or
Neutral.
If belt restraint system, starter interlock sys¬
tem, or reminder system does not work as de¬
scribed, see your dealer for information and
assistance.
LAP BELTS For Rear Seat and Center Front
Seat Passengers
• Seating positions next to side windows
have retractors which are designed to au¬
tomatically take up excess webbing.
These belts should be positioned and
secured as described above under "Lap-
Shoulder Belt Combination".
• Lap belts at center seating positions also
should be positioned and secured as de-
FIG. 1-20: CENTER BELT ADJUSTMENT

FIG. 1-21: OPTIONAL SHOULDER BELTS
shoulder belt can provide additional pro¬
tection by preventing or minimizing im¬
pact with the car interior by restraining
forward motion of the upper torso in a
collision. This is particularly true in the
case of a frontal force impact.
r——' — — —-——;
j CAUTION: Do not wear shoulder belt:

scribed above, and adjusted to a SNUG
FIT by pulling on the end of the belt ex¬
tending from the adjustable latch plate,
Fig. 1-20.
• To lengthen lap belt at center seating po¬
sitions place adjustable latch plate at
right angles to the belt webbing and pull
on latch plate; belt should then slide eas¬
ily through the adjustment feature.
OPTIONAL SHOULDER BELTS For Rear Seat
Outboard Passengers and Front Seat on Con¬
vertibles, Fig. 1-21.

• To fasten the detachable shoulder belt,
unstow it and place the knob on the
shoulder belt end into the keyhole on the
lap belt latch plate. (The latch is designed
so that this attachment can only be com¬
pleted before fastening the lap belt.) Tilt
the knob as necessary, to pass it through
the slot. Pull the knob firmly upward to
seat it at the narrow end of the keyhole,
then fasten the lap belt. Reverse this pro¬
cedure when removing and restowing
the shoulder belt.
• The detachable shoulder belts are
lengthened and shortened in the same
manner as center seat lap belts.
• The detachable shoulder belt should
have sufficient slack to insert a fist's
width between your chest and the belt.
This can be checked by inserting a
clenched fist between the belt and your
chest with thumb against chest and back
of hand facing upward, Fig. 1-22.
CONVERTIBLE SHOULDER BELT STOWAGE
On convertible models, front seat shoulder
belts (if so equipped) are stowed by inserting
the shoulder belt end into the retainer located
on the lower front edge of the rear seat cush¬
ion. Push down until the knob snaps securely
into position.

BELT RESTRAINT INSPECTION
• Periodically inspect belts, buckles, ad¬
justable latch plates, retractors, interlock
and reminder systems, guide loops, clips,
and anchors for damage that could lessen
the effectiveness of the restraint system.
• Keep sharp edges and damaging objects
away from belts, and other parts of re¬
straint system.
• Replace belts if cut, weakened, frayed, or
subjected to collision loads.
• Check that anchor mounting bolts are
tight.
• Have questionable parts replaced.
• Keep seat belts clean and dry.
• Clean only with mild soap solution and
lukewarm water.
• Do not bleach or dye belts since this may

Child Restraint
NOTE: If your vehicle is equipped with the
optional Air Cushion Restraint System
(ACRS), the Child Restraint information in the
ACRS Supplement to this owner's manual ap¬
plies instead of this section.
Children in automobiles should be re¬
strained to lessen the risk of injury in accidents
or sudden stops. General Motors dealers offer
restraint systems designed specifically for use
with infants and with small children. The GM
"Infant Love Seat" is designed for babies up to
20 pounds. Fig. 1-23. The GM "Child Love
Seat" is designed for children weighing 20 to
40 pounds, up to 3 feet-4 inches in height,
who are able to sit up alone. Fig. 1-24.
In using any infant or child restraint system,
FIG. 1-24: CHILD LOVE SEAT
read and comply with all installation and
usage instructions.
If a child is traveling in a vehicle not equip¬
ped with a General Motors infant or child
restraint or other appropriate infant or child
restraint system, the following precautions
should be taken:
1. Infants unable to sit up by themselves
should be restrained by placing them in
a covered, padded bassinet which is
FIG 1-23: INFANT LOVE SEAT

placed crossways in the vehicle (width-
wise) on the rear seat. The bassinet
should be securely restrained with the
regular vehicle belt restraints. An alter¬
nate method is to position the bassinet so
that it rests against the back of the front
seat, again crossways in the vehicle.
2. Children able to sit up by themselves
should be placed on a seat and re¬
strained with a belt restraint. When chil¬
dren ride in the front seat, both lap and
shoulder belt should be worn. If the
shoulder belt causes neck or face irrita¬
tion due to the child's size, this may be
reduced in some cases by positioning
the child further inboard. If serious dis¬
comfort continues, the child should be
lap belted in the rear seat. Never allow a
child to stand or kneel on any seat.
3. General Motors recommends that chil¬
dren be restrained properly when riding.
However, if unusual conditions prohibit
use of restraints and require that a child
must stand, he should stand on the floor
directly behind the front seat. This will
help minimize the possibility of injury
from frontal force impacts in the event of
such an accident.
Trailer Towing
Since passenger cars are designed and in¬
tended to be used primarily as passenger con¬
veyances, towing a trailer will affect handling,
durability and economy. Maximum safety and
satisfaction depend upon proper use of correct
equipment and avoiding overloads and other
abusive operation.
It is recommended that your new Cadillac
be operated for 500 miles before trailer tow¬
ing. If it is necessary to tow during this period,
avoid speeds over 50 mph and full throttle
starts. The same precautions should be ob¬
served when a new engine or axle is installed
in your car.
The maximum loaded trailer weight which
you can pull with your Cadillac Calais, De-
Ville, Brougham or Eldorado depends on what
special equipment has been installed on your
car. Cadillac does not recommend towing any
trailer over 1,000 lbs. gross trailer weight un¬
less the car has the required equipment. In any
case, however, towing a trailer with the Cadil¬
lac Series Seventy-Five is not recommended.
The following chart shows the required and
recommended added equipment for pulling
various sizes of trailers.
| CAUTIONS:
11. A frame side rail mounted load dis¬
tributing hitch with sway control of
sufficient capacity is required for trail-
| ers over 2,000 lbs. loaded weight.
• 2. Do not use axle-mounted hitches. They
can cause damage to the axle housing,
I wheel bearings, wheels or tires.
I 3. Trailer brakes are required on trailers
over 1,000 lbs. loaded weight.
I 4. Do not tap into the car's hydraulic
I brake system if operation of the trailer
! brake system requires more than 0.02
cubic inch of fluid displacement from
■ the car's master cylinder. The car's
| master cylinder fluid capacity will not
I be sufficient to operate both car and
; trailer brakes under all conditions of
use if more than 0.02 cubic inch of
fluid displacement is required.
I 5. Whenever a trailer hitch is removed,
be certain to have any mounting holes
i in the underbody properly sealed to
I prevent possible entry of exhaust
( fumes, dirt or water. (See Engine Ex-
| haust Gas Caution.)

Use only trailer hitches which permit j
normal operation of the Energy Ab- J
sorbing Bumper system. For example, a |
rigid fore and aft connection between |
the bumper and any other part of the '
vehicle should be avoided, otherwise |
damage may be increased in the event >
of a collision.
MAINTENANCE
More frequent vehicle maintenance is re¬
quired when using your car to pull a trailer.
Change the:
• Automatic transmission fluid each
50,000 miles,
• Axle or final drive lubricant each 15,000
miles,
• Engine oil each 90 days or 3,000 miles,
whichever occurs first,
• Positive crankcase ventilation valve each
12 months or 15,000 miles, whichever
occurs first.
• See Index and Maintenance Schedule
Folder for important information on en¬
gine belts, cooling system care, and au¬
tomatic brake adjustment.

Check Automobile and Trailer Compo¬
nents Regularly—Trailer towing places extra
stress on a car's mechanical components. The
steering, transmission, tires, brakes, engine
and cooling system and the electrical system
should be in top operating condition before
embarking on a trip. Here are some sugges¬
tions that can save you time, trouble and ex¬
pense:
1. Check the hitch ball for wear. Keep it
lubricated with a light coat of chassis
grease. Inspect electrical connections
for proper contact. Check condition of
safety chains.
2. Inspect tires and maintain recom¬
mended pressures.
3. Check brake systems often. Make a few
test stops before taking to the open road.
Make certain both trailer and car brakes
are operating properly.
4. Check brake lights, turn indicators, and
running lights frequently.
5. Check all systems having a specified
fluid capacity regularly for proper level.
6. Check that your car is not overdue for
important services such as oil change,
engine tune-up, wheel alignment, and
wheel balancing.
7. C heck cooling system to see that it is
clean and rust-free.
HITCHES
To assist in attaining good handling of the
car-trailer combination, it is important that
trailer tongue load be maintained at approxi¬
mately 10% of the loaded trailer weight. Ton¬
gue load can be adjusted by proper distribu¬
tion of the load in the trailer and can be
checked by weighing separately the loaded
trailer and then the tongue.
Adjusting Load Distributing Hitch If Your
Cadillac Is Equipped With Automatic Level
Control
IMPORTANT: Vehicle must have full gas
tank, spare tire in place, but no passengers or
luggage.
1. Exhaust all air from system as follows:
Exhaust compressor tank using service
valve. Exhaust shock absorbers by jack¬
ing rear of car above normal height.
Hold until no further air is exhausted ...
about 2 minutes.
2. Install frame-mounted hitch and set ball
height as specified by trailer manufac¬
turer with ail air exhausted as in Step 1
above.
3. Hook up trailer and adjust tension on
load distributing bars per hitch
manufacturer's specifications with all air
exhausted as in Step 1. Note this adjust¬
ment.
4. Compressor will recharge the leveling
system within 15 to 20 minutes of nor¬
mal driving.
5. On all future trailer hook-up>s. simply
attach trailer with the load distributing
bars set to the previously determined ad¬
justment.
6. The procedure described above applies
to all types of frame-mounted load dis¬
tributing hitches.
BRAKES
If a trailer brake is to be used with your
Cadillac make sure you follow the recom¬
mendations of the trailer brake manufacturer
for installation of the compronents required for
trailer brake actuation and balance. Refer to
the preceding cautions (three and four) regard¬
ing car and trailer brakes.
All hydraulic compronents must be capable
of withstanding 3000 psi. The hydraulic con-
