CAUTION!
• When installing the power distribution
center cover, it is important to ensure
the cover is properly positioned and fully
latched. Failure to do so may allow water
to get into the power distribution center
and possibly result in an electrical sys-
tem failure.
• When replacing a blown fuse, it is impor-
tant to use only a fuse having the correct
amperage rating. The use of a fuse with
a rating other than indicated may result
in a dangerous electrical system over-
load. If a properly rated fuse continues
to blow, it indicates a problem in the
circuit that must be corrected.
JACKING AND TIRE CHANGING
Jack Location
The jack and jack tools are stored under the
front passenger seat.
Removal Of Jack And Tools
• To access the jack and jack tools you must
remove the plastic access cover, located on
the side of the seat. To remove the cover,
pull the front part of the cover (closest to
the front of the seat) toward you to release a
locking tab. Once the front of the cover is
loose, slide the cover toward the front of the
seat until it is free from the seat frame.

NOTE:
Always stow the spare tire with the valve stem
facing the ground. It is recommended that
you stow the flat or spare to avoid tangling the
loose cable.NOTE:
The winch mechanism is designed for use
with the extension tube only. Use of an air
wrench or other power tools is not recom-
mended and can damage the winch.
Preparations For Jacking
1. Park the vehicle on a firm, level surface.
Avoid ice or slippery areas.
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 being hit
when operating the jack or changing the
wheel.
2. Place the gear selector into PARK. On four-wheel drive vehicles, shift the trans-
fer case to the 4L position.
3. Turn on the Hazard Warning flasher.
4. Apply the parking brake.
5. Turn the ignition OFF. 6. Block both the front and rear of the wheel
diagonally opposite the jacking position.
For example, if the right front wheel is
being changed, block the left rear wheel.
NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.

Jacking Instructions
1. Remove the spare wheel, jack, and toolsfrom storage.
2. Using the lug wrench, loosen, but do not remove, the lug nuts by turning them
counterclockwise one turn while the
wheel is still on the ground. 3. Placement of the jack is critical:
NOTE:
Keep the jack and tools aligned while raising
the vehicle
1500 Series Trucks (4x2 And 4x4)
• When changing a front wheel, place the
scissors jack under the rear portion of the
lower control arm as shown below.
NOTE:
Access the front jacking location from behind
the front tire, and rear jacking location from
behind the rear tire. • Operate the jack using the extension with
the jack hook and the lug wrench. The
extension tubes may be used but is not
required.

• When changing a rear wheel, assemble theextension with the jack hook to the jack and
connect the extension tubes. Place the jack
under the axle between the wheel and the
shock bracket with the extension with the
jack hook extending to the rear.
• Connect the extension tubes and lug wrench.
2500/3500 Series Trucks (4x2 And 4x4)
• Operate the jack using the extension with the jack hook and the lug wrench. The
extension tubes may be used but is not
required. • When changing the front wheel, assemble
the jack driver to the jack and connect the
jack driver to the extension tubes. Place the
jack under the axle as close to the tire as
possible with the drive tubes extending to
the front. Connect the extension tubes and
lug wrench.
NOTE:
Access the front jacking location from in front
of the front tire, and rear jacking location
from behind the rear tire.

When changing a rear wheel, assemble the
jack driver to the jack and connect the jack
driver to the extension tubes. Place the jack
under the axle between the spring and the
shock absorber with the extension tubes ex-
tending to the rear.• Connect the extension tubes and lugwrench.
NOTE:
If the bottle jack will not lower by turning the
dial (thumbwheel) by hand, it may be neces-
sary to use the jack driver in order to lower the
jack.
• By rotating the lug wrench clockwise, raise the vehicle until the wheel just clears the
surface.
• Remove the lug nuts and pull the wheel off. On single rear-wheel (SRW) trucks, install
the spare wheel and lug nuts with the cone
shaped end of the lug nuts toward the
wheel. On 3500 dual rear-wheel models (DRW) the lug nuts are a two-piece assem-
bly with a flat face. Lightly tighten the lug
nuts. To avoid the risk of forcing the vehicle
off the jack, do not fully tighten the lug nuts
until the vehicle has been lowered.
• Using the lug wrench, finish tightening the lug nuts using a crisscross pattern. Refer to
“Torque Specifications” in “Technical
Specifications” for the correct tightness. If
in doubt about the correct tightness, have
them checked with a torque wrench by your
authorized dealer or at a service station.
• Install the wheel center cap and remove the wheel blocks. Do not install chrome or alu-
minum wheel center caps on the spare
wheel. This may result in cap damage.
• Lower the jack to its fully closed position. If the bottle jack will not lower by turning the
dial (thumb wheel) by hand, it may be
necessary to use the jack driver in order to
lower the jack. Stow the replaced tire, jack,
and tools as previously described.
• Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated lug nuts.

WARNING!
• If working on or near a roadway, beextremely careful of motor traffic.
• To assure that spare tires, flat or
inflated, are securely stowed,
spares must be stowed with the
valve stem facing the ground.
• Raising the vehicle higher than nec-
essary can make the vehicle less
stable. It could slip off the jack and
hurt someone near it. Raise the ve-
hicle only enough to remove the
tire.
• To avoid the risk of forcing the ve-
hicle off the jack, do not fully
tighten the wheel bolts until the
vehicle has been lowered. Failure to
follow this warning may result in
personal injury.
• To avoid possible personal injury,
handle the wheel covers with care to
avoid contact with any sharp edges.
WARNING!
• A loose tire or jack thrown forward ina collision or hard stop could en-
danger the occupants of the ve-
hicle. Always stow the jack parts
and the spare tire in the places
provided.
• A loose tire thrown forward in a
collision or hard stop could injure
the occupants in the vehicle. Have
the deflated (flat) tire repaired or
replaced immediately.
CAUTION!
• Do not attempt to raise the vehicle byjacking on locations other than those
indicated in the Jacking Instructions for
this vehicle.
• Before raising the wheel off the ground,
make sure that the jack will not damage
surrounding truck parts and adjust the
jack position as required.
• Use a back and forth motion to remove
the hub cap. Do not use a twisting mo-
CAUTION!
tion when removing the hub cap, dam-
age to the hub cap; finish may occur.
• The rear hubcaps on the dual rear wheel
has two pry off notches. Make sure that
the hook of the jack handle driver is
located squarely in the cap notch before
attempting to pull off.
Reinstalling The Jack And Tools
1500 Series Trucks
1. Tighten the jack all the way down by turning the jack turn-screw clockwise un-
til the jack is snug.

HOISTING
A conventional floor jack may be used at the
jacking locations. Refer to the graphics that
show jacking locations. However, a floor jack
or frame hoist must never be used on any
other parts of the underbody.
CAUTION!
Never use a floor jack directly under the
differential housing of a loaded truck or
damage to your vehicle may result.
TIRES
Tire Safety Information
Tire safety information will cover aspects of
the following information: Tire Markings, Tire
Identification Numbers, Tire Terminology and
Definitions, Tire Pressures, and Tire Loading.
Tire MarkingsNOTE:
• P (Passenger) — Metric tire sizing is basedon U.S. design standards. P-Metric tires
have the letter “P” molded into the sidewall
preceding the size designation. Example:
P215/65R15 95H.
• European — Metric tire sizing is based on European design standards. Tires designed
to this standard have the tire size molded
into the sidewall beginning with the section
width. The letter "P" is absent from this tire
size designation. Example: 215/
65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on U.S. design standards. The size
designation for LT-Metric tires is the same
as for P-Metric tires except for the letters
“LT” that are molded into the sidewall pre-
ceding the size designation. Example:
LT235/85R16.
• Temporary spare tires are designed for tem- porary emergency use only. Temporary high
pressure compact spare tires have the letter
“T” or “S” molded into the sidewall preced-
ing the size designation. Example: T145/
80D18 103M.
