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 specifica -
tions refer to “Wheel And Tire Torque Specifications” 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. 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 previ -
ously described.
9. Adjust the tire pressure when possible.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. 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.

IN CASE OF EMERGENCY 399
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 posi -
tive battery post. Do not jump off fuses. Only jump directly
off positive post which has a positive (+) symbol on or
around the post.
Positive Battery Post 1. Apply the parking brake, shift the automatic transmis -
sion into PARK (P) and turn the ignition OFF.
2. Turn off the heater, radio, and all unnecessary electrical
accessories.
3. If using another vehicle to jump start the battery, park the
vehicle within the jumper cables’ reach, apply the
parking brake and make sure the ignition is OFF. 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.

SERVICING AND MAINTENANCE 411
Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look for unusual
wear or damage. Rotate at the first sign of irregular wear.
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and automatic transmis -
sion (six-speed only), and fill as needed.
• Check function of all interior and exterior lights. Maintenance Plan
Required Maintenance
Refer to the maintenance plan on the following pages for
required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.
• Inspect battery and clean and tighten terminals as required.
• Inspect automatic transmission fluid if equipped with dipstick.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect front end, and lubricate — If equipped with serviceable fittings. 7

3. There are travel stops on both sides of the glove compart -
ment. Push inward on right side of the glove compart -
ment travel stop to disengage the stop. Then pull the right
of the glove compartment outward (away from the hinge)
to disengaging the right side of the compartment from the
hinge. Continue by removing the left side from the hinge
by slightly lowering the compartment while pulling
outward until it is completely disengaged from the hinge.
Glove Compartment 4. Remove the filter cover by pushing in on the finger tabs
on each end of the filter cover.

Drain And Refill
On 4500/5500 vehicles, remove the lower bolt to drain the
axle fluid.
4500/5500 Rear Axle Plugs
Refer to “Scheduled Servicing” in this chapter for the proper
maintenance intervals. Lubricant Selection
Refer to “Fluids And Lubricants” in “Technical Specifica -
tions” for further information.
NOTE:
The presence of water in the gear lubricant will result in
corrosion and possible failure of differential components.
Operation of the vehicle in water, as may be encountered in
some off-highway types of service, will require draining and
refilling the axle to avoid damage.
Limited-Slip Differentials DO REQUIRE limited slip oil
additive (friction modifiers).
NOTE:
Slight noise and mild shuddering may be evident while
turning a vehicle with limited slip differential on concrete or
dry pavement. These conditions should be considered
normal operation of the limited slip differential.1 — 4500/5500 Rear Axle Fluid Fill Plug
