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 system failure.
When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indi -
cated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must
be corrected.

6. Finish tightening the lug nuts. Push down on
the lug wrench while at the end of the
handle for increased leverage. Tighten the
lug nuts in a star pattern until each nut has
been tightened twice. For the correct lug nut
torque refer to “Wheel And Tire Torque
Specifications” in “Technical Specifi -
cations”. If in doubt about the correct
tightness, have them checked with a torque
wrench by an authorized dealer or service
station.
7. Install the wheel center cap and remove the 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.
Stow the replaced tire, jack, and tools as
previously described.
NOTE:
The bottle 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.
9. Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated lug nuts.
TO STOW THE FLAT OR SPARE
NOTE:
Have the flat tire repaired or replaced immedi -
ately.

1. Turn the wheel so that the valve stem is facing the ground and toward the rear of
the vehicle for convenience in checking the
spare tire inflation. Slide the wheel retainer
through the center of the wheel.

Reinstalling The Retainer

2. Lift the spare tire with one hand to give clearance to tilt the retainer at the end of
the cable and position it properly across the
wheel opening.
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.
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. Have the deflated (flat) tire repaired
or replaced immediately.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GAS ENGINE
Your vehicle is equipped with an automatic oil
change indicator system. The oil change
indicator system will remind you that it is time to
take your vehicle in for scheduled maintenance.

Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent
short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required”
message is displayed. Severe Operating
Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km)
since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles
(805 km).

An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change.If a scheduled oil change is performed by
someone other than an authorized dealer, the
message can be reset by referring to the steps
described under “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel”.
NOTE:
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Severe Duty All Models
NOTE:
Change Engine Oil at 4,000 miles (6,500 km) or
350 hours of engine run time if the vehicle is
operated in a dusty and off road environment or
is operated predominantly at idle, or only very
low engine RPM. This type of vehicle use is
considered Severe Duty.
Once A Month Or Before A Long Trip:Check engine oil level
Check windshield washer fluid level
Check tire pressure and look for unusual
wear or damage. Rotate tires at the first sign
of irregular wear, even if it occurs before the
oil indicator system turns on.
Check the fluid levels of the coolant reservoir,
brake master cylinder, power steering and
automatic transmission (six-speed only) and
fill as needed
Check function of all interior and exterior
lights7

MAINTENANCE PLAN — GASOLINE ENGINE
Required Maintenance
Refer to the Maintenance Plan on the following pages for required maintenance. More frequent maintenance may be needed in severe conditions, such
as dusty areas and very short trip driving. In some extreme conditions, additional maintenance not specified in the maintenance schedule may be
required.
NOTE:
Using white lithium grease, lubricate the door hinge roller pivot joints twice a year to prevent premature wear.
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 battery and clean and tighten terminals as required.
Inspect the CV/Universal joints.
Inspect brake pads, shoes, rotors, drums, hoses and park brake.
Inspect engine cooling system protection and hoses.
Inspect exhaust system.
Inspect engine air cleaner if using in dusty or off-road conditions. If required, replace air cleaner filter.
Inspect and replace the Evaporative System Fresh Air Filter as necessary, replacement may be more frequent if vehicle is operated in extreme
dusty conditions.

short trip driving. In some extreme conditions,
additional maintenance not specified in the
maintenance schedule may be required.
At Each Stop For Fuel
Check the engine oil level at least 30 minutes
after a fully warmed engine is shut off. Checking
the oil level while the vehicle is on level ground
will improve the accuracy of the oil level
reading. Add oil only when the level is at or
below the ADD or MIN mark. Once A Month
Inspect the batteries, and clean and tighten
the terminals as required.
Check the fluid levels of the coolant reservoir,
brake master cylinder, and automatic trans-
