Removing the Wheel Covers and the
Wheel Nut Caps
Removing the Center Wheel Cap
Your vehicle may have
center caps if equipped
with aluminum wheels.
To remove a center cap use the wheel wrench to pry
gently at the notch in the wheel cap. Don't use a
tool that is narrower than the wheel wrench to pry at
the notch.
Removing the Wheel Covers
If your vehicle is equipped
with wheel covers, loosen
the plastic nut caps
with the wheel wrench in a
counter clockwise
direction.
If needed, you can ®nish loosening them with your
®ngers. Then, using the ¯at end of the wheel wrench,
pry along the edge of the cover until it comes off.
The edge of the wheel cover could be sharp, so don't
try to remove it with your bare hands.

2. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground for the compact spare tire to ®t underneath
the wheel well of the vehicle. Remove all wheel
nuts and take off the ¯at tire.3. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if you need to, to
get all the rust or dirt off.

{CAUTION:
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.

nuts with the rounded
end of the nuts
toward the wheel.
Tighten each nut by
hand until the wheel is

Electrical System
Add-On Electrical Equipment
Notice:Don't add anything electrical to your
vehicle unless you check with your dealer ®rst.
Some electrical equipment can damage your vehicle
and the damage wouldn't be covered by your
warranty. Some add-on electrical equipment can
keep other components from working as they
should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-60.
Headlamp Wiring
The headlamp circuit is protected by individual fuses in
the underhood fuse block. An electrical overload will
cause the fuse to blow. If this happens, have your
headlamp system checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, have
it ®xed.

Power Windows and Other Power
Options
A circuit breaker in the driver's side instrument panel
fuse block protects the power windows and other power
accessories. When the current load is too heavy, the
circuit breaker opens and closes, protecting the
circuit until the problem is ®xed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses. This greatly
reduces the chance of ®res caused by electrical
problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
