WARNING!(Continued)
•If working on or near a roadway, be extremely
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.
CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the Jacking
Instructions for this vehicle.
1. If equipped, remove the spare wheel, jack, and tools from 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. When changing the front wheel, assemble the jack driver to the jack and connect the jack driver to the
extension tube. Place the jack under the axle as close to
the tire as possible with the jack driver extending to the
front. Connect the extension tubes and lug wrench.

IN CASE OF EMERGENCY 339

When changing a rear wheel, assemble the jack driver to
the jack and connect the jack driver to the extension tubes.
Securely place the jack under the sway bar bracket (unless
both tires are flat on one side, then place jack under shock
bracket) facing forward in vehicle. Connect the extension
tubes and lug wrench.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.
NOTE:
If the jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to use the jack
driver in order to lower the jack.
4. By rotating the lug wrench clockwise, raise the vehicle until the wheel just clears the surface.

WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.
5. Remove the lug nuts and pull the wheel off. Install the spare wheel and lug nuts with the cone shaped end of
the nuts toward the wheel on single rear wheel (SRW)
models. On 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 lug wrench, finish tightening the nuts using a crisscross pattern. For the proper lug nut torque speci-
fications refer to “Wheel And Tire Torque Specifica-
tions” in “Technical Specifications.” If in doubt about
the correct tightness, have them checked with a torque
wrench by an authorized dealer or at a service station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop, could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided.
7. Install wheel center cap (if equipped) 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 (thumbwheel) 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.
9. Adjust the tire pressure when possible.
Dual Rear Wheels
Slots in the wheels will assist in properly orienting the
inner and outer wheels. Align these slots when assembling
the wheels for best access to the tire valve on the inner
wheel. The tires of both dual wheels must be completely off
the ground when tightening to insure wheel centering and
maximum wheel clamping.

Preparations For Jump Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE:The positive battery post may be covered with a
protective cap if equipped. Lift up on the cap to gain access
to the positive battery post. Do not jump off fuses. Only
jump directly off positive post which has a positive (+)
symbol on or around the post.
WARNING!
• Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is ON. You can be injured by moving fan
blades.
• Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Apply the parking brake, shift the automatic transmis- sion into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electrical accessories.

Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.
WARNING!
•Use only refrigerants and compressor lubricants ap-
proved by the manufacturer for your air conditioning
system. Some unapproved refrigerants are flam-
mable and can explode, injuring you. Other unap-
proved refrigerants or lubricants can cause the sys-
tem to fail, requiring costly repairs. Refer to
Warranty Information Book, for further warranty
information.

WARNING! (Continued)
•The air conditioning system contains refrigerant un-
der high pressure. To avoid risk of personal injury or
damage to the system, adding refrigerant or any
repair requiring lines to be disconnected should be
done by an experienced technician.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condition-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.

Conditions that would require replacement:
•Rib chunking (one or more ribs has separated from belt
body)
• Rib or belt wear
• Longitudinal belt cracking (cracks between two ribs)
• Belt slips
• “Groove jumping (belt does not maintain correct posi-
tion on pulley)
• Belt broken (note: identify and correct problem before
new belt is installed) •
Noise (objectionable squeal, squeak, or rumble is heard
or felt while drive belt is in operation)
Some conditions can be caused by a faulty component such
as a belt pulley. Belt pulleys should be carefully inspected
for damage and proper alignment.
Belt replacement on some models requires the use of
special tools, we recommend having your vehicle serviced
at an authorized dealer.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should be
lubricated periodically with a lithium based grease, such as
Mopar Spray White Lube to assure quiet, easy operation
and to protect against rust and wear. Prior to the applica-
tion of any lubricant, the parts concerned should be wiped
clean to remove dust and grit; after lubricating excess oil
and grease should be removed. Particular attention should
also be given to hood latching components to ensure
proper function. When performing other underhood ser-
vices, the hood latch, release mechanism and safety catch
should be cleaned and lubricated.
Accessory Belt (Serpentine Belt)
376 SERVICING AND MAINTENANCE

The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as Mopar Lock
Cylinder Lubricant directly into the lock cylinder.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild nonabrasive cleaner. This will remove accumulations
of salt or road film.
Operation of the wipers on dry glass for long periods may
cause deterioration of the wiper blades. Always use washer
fluid when using the wipers to remove salt or dirt from a
dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor perfor-
mance of blades may be present with chattering, marks,
water lines or wet spots. If any of these conditions are
present, clean the wiper blades or replace as necessary. The wiper blades and wiper arms should be inspected
periodically, not just when wiper performance problems
are experienced. This inspection should include the follow-
ing points:
•
Wear Or Uneven Edges
• Foreign Material
• Hardening Or Cracking
• Deformation Or Fatigue
If a wiper blade or wiper arm is damaged, replace the
affected wiper arm or blade with a new unit. Do not
attempt to repair a wiper arm or blade that is damaged.
Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back against the
glass without the wiper blade in place or the glass may
be damaged.
