When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell if your tires are properly inated
simply by looking at them. Radial tires may look properly
inated even when they’re underinated. Check the tire’s
ination pressure when the tires are cold. Cold means
your vehicle has been sitting for at least three hours or
driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to get a
pressure measurement. If the cold tire ination pressure
matches the recommended pressure on the Tire and
Loading Information label, no further adjustment is
necessary. If the ination pressure is low, add air until
you reach the recommended amount.
If you overll the tire, release air by pushing on the
metal stem in the center of the tire valve. Recheck the
tire pressure with the tire gage.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.
Check Tire Pressure System
If your vehicle has this feature, the check tire pressure
system can alert you to a large change in the
pressure of one tire. The system will not alert you
before you drive that a tire is low or at. You must begin
driving before the system will work properly.
The TIRE PRESSURE LOW message will appear on
the Driver Information Center (DIC) if pressure difference
(low pressure) is detected in one tire. The check tire
pressure system may not alert you if:
More than one tire is low.
The vehicle is moving faster than 65 mph
(105 km/h).
The system is not yet calibrated.
The tire treadwear is uneven.
The compact spare tire is installed.
Tire chains are being used.
The vehicle is being driven on a rough or
frozen road.
If the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
Anti-Lock Brake System Warning Light on page 3-39.

Changing a Flat Tire
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your
hazard warning ashers.
{CAUTION:
Changing a tire can cause an injury. The
vehicle can slip off the jack and roll over you
or other people. You and they could be badly
injured. Find a level place to change your tire.
To help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won’t
move, you can put blocks at the front and rear
of the tire farthest away from the one being
changed. That would be the tire on the other
side of the vehicle, at the opposite end.The following steps will tell you how to use the jack and
change a tire.

Removing the Flat Tire and Installing
the Spare Tire
1. If your vehicle is equipped with the 8 inch (20 cm)
hubcap, use the wheel wrench to begin loosening
the plastic wheel nut caps. Once you have loosened
the plastic wheel nut caps with the wheel wrench,
you can nish loosening them with your ngers.
Once the plastic wheel nuts have been loosened,
pull the hubcap off by hand.
If your vehicle is equipped with either the 2 1/2 inch
(6 cm) or the 4 inch (10 cm) hubcap, rst remove
the decorative nut caps using the wheel wrench.
2. Then use the wheel wrench to loosen the wheel
nuts, but do not remove them yet.
3. The jack has a bolt at
the end. Attach the
wheel wrench to
the bolt to create a
jack handle.4. Turn the wheel wrench counterclockwise to lower
the jack head until it ts under the vehicle.
5. Near each wheel well is a notch in the plastic trim
panel to position the jack head. You will nd the word
JACK and an arrow stamped into the plastic near
each notch. Position the jack under the vehicle and
raise the jack head until it ts rmly against the sheet
metal next to the word JACK. Do not raise the vehicle
yet. Put the compact spare tire near you.

{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to t the
jack lift head into the proper location before
raising the vehicle.6. Raise the vehicle by turning the wheel wrench
clockwise in the jack. Raise the vehicle far
enough off the ground so there is enough room
for the compact spare tire to t underneath
the wheel well.
5-83

9. Install the compact spare tire on the wheel-mounting
surface.
10. Then reinstall the
wheel nuts with the
rounded end of
the nuts toward the
wheel. Tighten each
nut by hand until
the wheel is held
against the hub.
11. Lower the vehicle by turning the wheel wrench
counterclockwise. Lower the jack completely.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of damage
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.
There are four fuse blocks in your vehicle: the main and
auxiliary instrument panel fuse blocks, the underhood
fuse block and the rear fuse block.
Main and Auxiliary Instrument Panel
Fuse Blocks
The main and auxiliary instrument panel fuse blocks are
located under the instrument panel, on the passenger’s
side of the vehicle. Lamps, connectors and the
HVAC duct temperature sensors may need to be
disconnected and removed to allow access to these
fuse blocks.
Remove the hush panel on the passenger’s side to
reveal the fuses by performing the following steps:
1. Remove the two screws located along the front
edge of the panel.
2. Lower the hush panel.
3. Remove the fuse block cover.
4. Place the wide end of the fuse puller over the
plastic end of the fuse.
5. Squeeze the ends over the fuse and pull it out.
When nished, reinstall the fuse block cover and
the hush panel. Reinstall lamps, connectors and HVAC
duct temperature sensors if they were removed.
