WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel on 2500/3500 single rear
wheel (SRW) models. On 3500 dual rear wheel models
(DRW) the lug nuts are a two piece assembly with a flat
face. Lightly tighten the nuts. To avoid risk of forcing the
vehicle off the jack, do not fully tighten the nuts until the
vehicle has been lowered.
6. Using the wheel wrench, finish tightening the nuts
using a crisscross pattern. Correct nut tightness is 135 ft.
lbs. (183 N´m) torque for 2500/3500 single rear wheel(SRW) models and 145 ft. lbs. (197 N´m) for 3500 dual rear
wheel models. If in doubt about the correct tightness,
have them checked with a torque wrench by your dealer
or at a service station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle.
Always stow the jack parts and the extra tire and
wheel in the places provided.
7. Install wheel center cap and remove wheel blocks. Do
not install chrome or aluminum wheel center caps on the
spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. If the jack
will not lower by turning the dial (thumb wheel) by

JUMP-STARTING
WARNING!
To prevent personal injury or damage to clothing, do
not allow battery fluid to contact eyes, skin or
fabrics. Do not lean over a battery when connecting
jumper cables or allow cable clamps to touch each
other. Keep open flames or sparks away from battery
vent holes. Always wear eye protection when work-
ing with batteries.
Do not use a booster battery or any other booster
source that has a greater than 12 volt system, i.e. do
not use a 24 volt power source.
NOTE:Replacement batteries should both be of equal
size to prevent damage to the vehicles charging system.
Your vehicle is equipped with two 12±volt batteries. If it
becomes necessary to use a booster battery, with jumper
cables, to start a vehicle's engine because its batteries are
discharged, the following procedure should be followed:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If indica-
tor (if equipped) is light or yellow on either battery,
replace that battery.

WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting
out the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
With Portable Starting Unit
There are many types of these units available. Follow the
manufacturer's instructions for necessary precautions
and operation.
CAUTION!
It is very important that the starting unit operating
voltage does not exceed 12 Volts D.C. or damage to
battery, starter motor, alternator, or electrical system
may occur.
FREEING A STUCK VEHICLE
If vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the gear
selector rhythmically between DRIVE and REVERSE,
while applying slight pressure to the accelerator.
In general, the least amount of accelerator pedal pressure
to maintain the rocking motion without spinning the
wheels or racing the engine is most effective. Racing the
engine or spinning the wheels, due to the frustration of
not freeing the vehicle, may lead to transmission over-
heating and failure. Allow the engine to idle with the

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
CARB emission control vehicles are equipped with a
sophisticated onboard diagnostic system called OBDII.
This system monitors the performance of the emissions,
engine, and automatic transmission control systems.
When these systems are operating properly, your vehicle
will provide excellent performance and fuel economy, as
well as engine emissions well within current government
regulations.
If any of these systems require service, the OBD II system
will turn on the ªMalfunction Indicator Light.º It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be driveable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
Prolonged driving with the ªMalfunction Indicator
Lightº on could cause further damage to the emis-
sion control system. It could also affect fuel economy
and driveability. The vehicle must be serviced before
any emissions tests can be performed.
If the ªMalfunction Indicator Lightº is flashing,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.

Apply a light film of lubricating oil to the sealing surface
of the filter gasket before installing the filter.
CAUTION!
Overtightening may distort the threads or damage
the filter element seal.
Install the filter as specified by the filter manufacturer.
Turn the filter 3/4 to one full turn after making contact
with the gasket.
Check the condition of the threads and sealing surface on
the oil pan and drain plug.
Install the drain plug and sealing washer and tighten to
37 ft-lbs. (50 N´m).Use only high-quality multi-grade lubricating oil in your
Cummins Diesel Engine. Choose the correct oil for your
operating conditions as outlined in the Selection of
Engine Oil.
Cummins Turbo Diesel
Fill the engine with the correct grade of new oil. The
engine capacity is 11 quarts (10.4 liters) in the crankcase
and 1 quart (.95 liter) in the lubricating oil filter.
Start the engine and operate it at idle for several minutes.
Check for leaks at the lubricating oil filter and oil pan
drain plug.
Stop the engine. Wait approximately 15 minutes to let the
oil in the upper parts of the engine drain back to the pan.
Check the oil level again.
Add oil as necessary to bring the level to the ªSAFEº
mark on the dipstick.

To determine the battery charge, check the battery test
indicator (if equipped) on top of each battery. If the test
indicator (if equipped) appears light or yellow, replace
the battery.
NOTE:Replacement batteries should both be of equal
capacity to prevent damage to the vehicle's charging
system.CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
negative post. Battery posts are marked (+) positive
and negative (-) and identified on the battery case.
Also, if a ªfast chargerº is used while battery is in
vehicle, disconnect both vehicle battery cables be-
fore connecting the charger to battery. Do not use a
ªfast chargerº to provide starting voltage.
WARNING!
Battery posts, terminals, and related accessories con-
tain lead and lead compounds. Always wash hands
after handling the battery.

It is important that proper lubricant is used in the
transmission. Refer to Recommended Fluids, Lubricants
and Genuine Parts for the correct lubricant type. A band
adjustment and filter change should be made at the time
of the oil change.
The fluid and filter should be changed and the bands
adjusted as specified in the Maintenance Schedule (Sec-
tion 8). Vehicles having severe usage should follow
Maintenance Schedule ªBº of the Maintenance Schedule
(Section 8).
Severe usage consists of:
²Off-the-highway operation;
²Trailer towing;
²Snow plow operation;
²Prolonged operation with heavy loading, especially in
hot weather.NOTE:If the transmission is disassembled for any
reason, the fluid and filter should be changed, and the
bands adjusted.
Special Additives
The manufacturer recommends against the addition of
any additives to the transmission. Exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. The use of transmission sealers should be avoided,
since they may adversely affect seals.
Front Wheel Bearings
Front wheel bearings for all Dodge Ram Trucks are
sealed-for-life. They do not require greasing or seal
replacement. In some instances, these bearings will
ªpurgeº excess grease and the bearing housing will look
slightly wet. This is normal.
²Periodic inspection for excess play is recommended.
