Good Rules to Remember:
Q
1. Operate the cold engine under a light load until
normal running temperature is reached.
2. Check the engine oil each time you stop for fuel.
3. Lubricate chassis every 1,000 miles. (See pages 20-21)
4. Change the oil regularly. (See pages 15-16)
5. Check air pressure in tires every week.
6. Inspect your battery every 4 weeks in winter and
every 2 weeks in summer.
7. Check transmission lubricant level every2,000 miles.
8. Service carburetor air cleaner every 6,000 miles
under normal conditions. Service oil filler pipe ap
air cleaner every 2,000 miles. ervicing hould be
done more frequently if mu ch driving i done on
dusty roads or through du st torm .
9.
Change the oil filter every 8,000 mil of normal
operation . In dusty area, or under dusty driving
conditions, change filter whenever oil app ar exces-
sively dirty.
10. Drain and refill the tran mission and r < r axle every
15, 000 miles.
11 . Flush cooling system by forced rev r e flow method
before filling with antifreeze in fall and after drain-
ing it in spring. Treat cooling y tern with "Rust
Resistor"after flushing. If antifr ze contains a rust
inhibitor, it will be unnecessary to add "Rust Re-
sistor" until the cooling y tern is drained and filled
with water.
12. Keep brakes in adjustment so that shoes contact
drums after 13/.&"-2" of pedal travel. Maintain brake

in the neutral position. If the engine is cold , proceed as follows:
1. Disengage the clutch.
2. Turn on ignition.
3. Press the starter pedal and keep starter engaged until engine
starts . (The starter pedal besides operating starter also opens
the throttle ;";3 automatically.)
Under Extremely Cold Startin~ Condition S- it is
advisable , to insure good starting , to pull out hand throttle
to give approximately one-third throttle opening.
NOTE: In case the engine should become over - choked at
any time , pull out the hand throttle all the way and oper-
ate starter continuously until engine starts. This will
eliminate further choking . If it becomes desirable to again
choke the carburetor for starting , push th e ha nd throttle
back to starting position.

REAR DECK
AND LUGGAGE
COMPARTMENT
The luggage compart-
ment of your Dodge
is unusually roomy,
providing plenty of
space for travelling
bags, golf or fishing
equipment, packages
and groceries. What's
more, it lights up in-
side
at night when the
tail-lights are on. And for your protection, it locks with its own
individual key.
In sedans , the spare wheel is on the right side of the luggage com-
partment. In club and convertible coupes, it is on the rear floor pan.
In 2-passenger coupes, it is back of the driver 's seat.
WARNINfJ-
LOCATION OF OIL BAYONET
The oil bayon et gauge is located on the
left side of the engine , between the start-
ing motor and the oil filler pipe. It is
marked at full and half-full. A third
marking , between these , indicates run-
nin g level. The full mark shows the
prop er oil level when the engine hasn't
been run for several hours. This level
drops somewhat upon starting the en-
gine,
however , because of filling the oil
passages
and fi1 ter.
CARBON' MONOXIDE
Never start or run an engine in
a closed garage. The exhaust
gases from all motor vehicles
are highly d angerous. They
contain carbon monoxide gas-
which is colorless, tasteless, and
odorless, but nevertheless is
a
deadly poison.

THE FIRST 2,500 MILES ARE
THE MO ~ ST IMPORTANT!
The Care You Give Your Car
During the First Few Months Can
Influence Its
Whole Life!
YOUR DODGE CAR is engineered and built with all, the care that
goes into the manufacture of a fine precision instrument - in many
cases, moving parts are fitted to the 10,000th of an inch. For that
reason, it will pay 'you to give it particular care during th e import an t
"breaking-in" period in order that it may continue to retu rn to you
the utmost in performance and satisfaction. The followi ng para-
graphs were written to help you give that necessary care with a
minimum of effort. We urge that you read them carefully and follow
the recommendations made. Then you will have every reason to
expect years of service and enjoyment from your Dodg e.
DRIVING SPEEDS
Your new Dodge car has been designed and built to high quality
standards, which will give you maximum efficiency and satisfaction.
A fine mechanism is deserving of proper treatment and you will get
the utmost satisfaction and freedom from inconvenienc with your
new Dodge car by giving it proper care and treatment at the outset.
Drive your car at moderate speeds until the engin has become
thoroughly warmed. Do not speed up the engine to warm it quickly.
This will assure proper lubrication and permit maximum fficiency.
Drive at moderate speeds, not over " 40", for the first 2SO miles at
least to "get acquainted" with your new car and do not drive it at
sustained high speeds during the first 1,000 miles.
Your new Dodge car, with reasonable care and opera ion, will give
you maximum comfort, safety and economy.
13

FIRST OIL CHANGE
AT 1,000 MILES
During the first 1,000 miles, it is recom-
mended that you use the engine oil which
is in the crankcase when the car is delivered.
If necessary to add oil during first 1,000
miles, No . 10-W should be used regardless
of the season or of climatic conditions.
After 1,000 miles, the crankcase should be drained (while the
engine is warm) and refilled with oil of the proper viscosity , accord-
ing to the atmospheric temperature expected . See page 15.

Pr o per lubrication is of vital importance to
the continued ' smooth operation of your
Dodge. That is why we urge you to keep
a close check on mileage and give your car
approved lubrication care at regular inter-
vals. The recommendations mad e here are
based on the results of years of solid expe-
rience and scientific test work. You can fol-
low
them with full assurance that you are
giving your car safe lubrication care.
ENGINE OI L RECOMMEND ATI O NS
AFTER 1000 MILES -When your speedometer registers 1000 miles,
the c
rankcase should be drained and refilled with the prope r vi s cosity
oil according to the a nt i cipated atmospheric ' temperatur e.
,
Oil ch an ges s ho uld then be made , un d er normal conditions , every
1500 to 2000 miles during winter and every 2500 to 3000 miles during
s umm er, according to the following recommendations :
\ ...
l:;tr: If you anticipate that the minim um ~~~
y :: ;:< ....... atmosphe ric temperature will be- .....-- ~
Not lo wer than + 32
0 F.. .Use S.A.E. 30
As l ow as + 100 F ... . .. ... Use No. 20 -W
As l ow as - 10
0 F..
... .... Use No. 10 -W
Below - 100 F ........ . . . .Use No. 10 -W plus 10% kerosene
T he interpretation of this table means that S.A. E. 30 is recommend ed as a
general summer oil for cars having a mileage above 1000. It may also be us ed in
tropical climates during t he win t er months where it is known that th e lowe st
temperature 'will not be lower than 32
0 F .,
and where the average te mp era tur e
will
be close to normal summer conditions .

WARNING! DUSTY DRIVING-Wh en a car is driven over
dusty roads or through dust storms, the danger of wear to internal
engine parts is increased, due to the amount of abrasive material
in the air. Normally, this material is kept out ot the engine by
the carburetor air deaner and the cr~nkcase . oil filler cap air
deaner. These should be deaned in kerosene and reoiled with
fresh engine oil as often as the carburetor
air deaner sump becomes half filled with
a semi-solid mixture · of oil aI)d dust. If
crankcase oil becomes con tam ina ted
through failure to service the units, drain
engine promptly and add new oil.
The use of No. 20-W oil should be confined principally to territories during
the winter months where mild winter conditions are known to prevail , and where
the temperature will not fal1 below 10° F. It must not be interpreted that No.
20-W cannot be used above 32° F. should temperatures rise and remain above
32° F . No . 20-W oil is satisfactory for use above 32° F., and a change of oil is,
therefore, not necessary until the regular mileage interval.
No . 10-W is recommended as a general winter oil in climates where normal
winter conditions prevail , and where temperatureS may fall as low as _10° F.,
but not lower. No. 10-W may also be used abov e 10° F., or above 32° F., with
safety should temperatures rise above these points during the winter months.
A change is, therefore , not necessary until the nex t mileage period.
For sub - normal winter conditions such as temperatures below -10° F., it is
recommended that No. 10-W be diluted with about 10% of colorless refined
kerosene. The kerosene should be mix ed thoroughly with the 10-W oil before
being added to the engine. In cases wh ere it is not convenient or desirable to do
this, consult your dealer or any reputabl e oil company as they will have specially
prepared oils to take care of thes e extrem ly low temperature conditions.
ALWA YS CHECK OIL LEVEL
Have the oil level checked each
time you stop for fuel. When the
oil drops below "Running Level"
on the indicator, add one quart of
oil. Never allow oil to drop below
the "Half-Full" mark.

Why Your Dodge is Equipped With
the Finest Type Oil Filter
Dirt and foreign material in the oil can seriously reduce the economy
and efficiency of any engine. To eliminate this danger, the finest type
of oil filter available is used in your Dodge. This removes dirt
and foreign material from 1: he oil until the filter itself becomes clogged.
When this happens, oil is still circulated to engine bearings , but
remains dirty, and so unsafe. Th erefore, it is advisable to install a
new oil filter every 8,000 miles, or, in dusty areas, when ever oil appears
to be excessively dirty.
Why Regular Crankcase Drqinage
Prolongs Engine Life
Because of the very nature of an automotive engine, fuel, water and
acid are constantly seeping into the engine oil and reducing its value
as a lubricant. In your Dodge , a special ventilating system expels
a
large amount of thes e undesirabl e elements, but enough re main to
make it advisable to drain the crankcase at the intervals recom-
mended in this booklet.
The accumulating non - lubricating elements in the engine oil have
a d~maging effect on highly finished steel surfac es. Fuel thins the
oil, thus reducing its value as a lubricant. Wat er has no lubricating
value, and is likely to freeze, thus causing a stoppag e of t he oil circu-
lation . Acid attacks metal surfaces , causing excessive w ea r. All of these
adulterating materials tend to form more rapidly as the temperature
goes down. For this reason , it is advisable to drain the engine oil
more frequently in cold than in warm weather.
The best time to drain the crankcas e is after a run , while the engine
is still
heated. Oil is thinner when hot, and will also be thoroughly
mixed from the circulation. It will, therefore, carry off sediment more
completely.
Never use kerosene for flushing out the oil pan and lubricating
system. A certain amount will remain in the system, collecting in
pockets from which it cannot be drained, and will dilute the oil.
