NOTE:The winch mechanism is designed for use with
the jack extension tube only. Use of an air wrench or other
power tools is not recommended and can damage the
winch.
Tire Changing Procedure
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
Do not raise this vehicle using a bumper jack. The jack is
designed as a tool for changing tires on this vehicle only.
It is not recommended that the jack be used for service
purposes or to lift more than one wheel at a time.
Preparations
Park the vehicle on a firm level surface, avoiding ice or
slippery areas. Set the parking brake and place the gear
selector in PARK (automatic transmission) or REVERSE
(manual transmission). On four-wheel drive vehicles,
shift the transfer case to the “4L” position.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.

•Turn on the Hazard Warning Flasher.
•Block both the front and rear
of the wheel diagonally oppo-
site the jacking position. For
example, if the right front
wheel is being changed, block
the left rear wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.
Instructions
WARNING!
Carefully follow these tire changing warnings to help
prevent personal injury or damage to your vehicle:
•Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the
vehicle.
•Block the wheel diagonally opposite the wheel to be
raised.
•Apply the parking brake firmly before jacking.
•Never start the engine with the vehicle on a jack.
•Do not let anyone sit in the vehicle when it is on a
jack.
•Do not get under the vehicle when it is on a jack.
•Only use the jack in the positions indicated.
•If working on or near a roadway, be extremely
careful of motor traffic.

4. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
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 hand, it may be necessary to use the jack drive tube in
order to lower the jack. Stow the replaced tire, jack, and
tools as previously described.
9. Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.
Hub Caps/Wheel Covers
The hub caps must be removed before raising the vehicle
off the ground.
For 2500/3500 single rear wheel (SRW) models, use the
blade on the end of the lug wrench to pry the hub cap off.
Insert the blade end into the pryoff notch and carefully
pop off the hub cap with a back and forth motion.
On 3500 models with dual rear wheels (DRW), you must
first remove the hub caps. The jack handle driver has a
hook at one end that will fit in the pry off notch of the
rear hub caps. Position the hook and pull out on the

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.
WHAT TO DO IN EMERGENCIES 367

Page 368 of 496
CAUTION!
Use the Jump Start Procedure only when the charge
indicator (if equipped) in both batteries is dark in
the center. Do not attempt jump starting when either
battery charge indicator (if equipped) is bright or
yellow. If charge indicator (if equipped) has a green
dot in the center, failure to start is not due to a
discharged battery and cranking system should be
checked.
1. Attach one jumper cable to the positive terminal of
booster battery and the other end of the same cable to the
positive terminal of the discharged battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
368 WHAT TO DO IN EMERGENCIES

2. Connect one end of the other jumper cable to negative
(-) post of booster battery. Connect the other end of the
jumper cable to a good ground on the engine block of the
vehicle with the discharged battery. Make sure a good
connection is made, free of dirt and grease.
WARNING!
•Do not connect the cable to the negative post of
the discharge battery. The resulting electrical
spark could cause the battery to explode.
•During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting jump start.
3. Take care that the clamps from one cable do not
inadvertently touch clamps from the other cable. Do not
lean over the battery when making connection. The
negative connection must provide good electrical con-
ductivity and current carrying capacity.
4. After the engine is started or if the engine fails to start,
cables must be disconnected in the following order: a. Disconnect the negative cable at the engine ground.
b. Disconnect the negative cable at the negative post
on booster battery.
c. Disconnect the cable from the positive post of both
batteries.

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
(automatic transmissions) and between 1st and RE-
VERSE (manual transmissions), 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
