Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See “Wiper Blade
Check” underPart B: Owner Checks and Services on
page 6-18for more information.
Replacement blades come in different types and are
removed in different ways.
To replace the wiper blade assembly, do the following:
1. Lift the windshield wiper arm away from
the windshield.2. Push the tab on the wiper blade assembly and pull
the assembly down enough to release it from the
U-hooked end of the wiper arm. Slide the assembly
away from the arm.
3. Remove the blade.
4. To reinstall the wiper blade assembly, slide it over
the wiper arm to engage the U-hooked end on the
wiper blade assembly. Pull up on the assembly
to lock it into place.
For the proper windshield wiper blade replacement
length and type, seeNormal Maintenance Replacement
Parts on page 5-97.

Check Tire Pressure System
If your vehicle has the check tire pressure system, it
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 CHECK TIRE PRESSURE 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.The check tire pressure system detects differences in
tire rotation speeds that are caused by changes in
tire pressure. The system can alert you about a
low tire — but it does not replace normal tire
maintenance. SeeTires on page 5-54.
When the CHECK TIRE PRESSURE message appears
on the Driver Information Center, you should stop as
soon as you can and check all your tires for damage. If
a tire is at, seeIf a Tire Goes Flat on page 5-69.
Also check the tire pressure in all four tires as soon as
you can. SeeInation - Tire Pressure on page 5-60.
Any time you adjust a tire’s pressure or have one
or more tires repaired or replaced, you will need to reset
(calibrate) the check tire pressure system. You will
also need to reset the system whenever you rotate the
tires, buy new tires and install or remove the compact
spare tire.
Do not reset the check tire pressure system without rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the check tire pressure system will not work properly
and may not alert you when a tire is low or high.

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 be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. 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 and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will not
move, you should 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, at the opposite end of the vehicle.When you have a at tire, use the following example
as a guide to assist you in the placement of
wheel blocks.
The following information will tell you next how to use
the jack and change a tire.
5-70

4. Turn the wheel wrench counterclockwise to lower
the jack head until it ts under the vehicle.5. Put the jack into a notch in the frame which is
located near each wheel well.
The front notch is 8 inches (20 cm) back from the
front wheel well. The rear notch is 3 inches
(8 cm) forward from the rear wheel well. The
notches are accessible through openings in the
plastic trim at the bottom of the vehicle.
6. Position the jack and raise the jack head until it ts
rmly on the ridge in the vehicle’s frame nearest the
at tire. Do not raise the vehicle yet.
5-73

7. 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.8. Raise the vehicle by turning the wheel wrench
clockwise in the jack. Raise the vehicle far
enough so there is enough room for the spare tire
to t under the wheel well.
9. Remove all the wheel nuts and take off the at tire.
5-74

13. Lower the vehicle by turning the wheel
wrench counterclockwise on the jack. Lower
the jack completely.
{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose
and even come off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque specication. SeeCapacities
and Specifications on page 5-96for wheel nut
torque specication.
Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specication. SeeCapacities and
Specifications on page 5-96for the wheel nut
torque specication.14. Tighten the wheel nuts
rmly in a crisscross
sequence.
Notice:Wheel covers will not t on your compact
spare. If you try to put a wheel cover on the compact
spare, you could damage the cover or the spare.
Do not try to put a wheel cover on your compact spare
tire. It will not t. Store the wheel cover and lug nut
caps in the trunk until you have the at tire repaired
or replaced.

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 airbag system. Before attempting to
add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-56.
Power Windows and Other
Power Options
Circuit breakers in the rear fuse block protect 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
or goes away.
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 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.
You will nd a fuse puller clipped in both of the fuse
blocks. Snap the wide end of the fuse puller at the side
indentations and pull the fuse out.
The MaxiFuses are located in two fuse blocks,
one located in the engine compartment on the
passenger’s side and the other under the rear seat on
the driver’s side. If a MaxiFuse should blow, have
your vehicle serviced by your dealer immediately.

Engine Compartment Fuse Block
The engine compartment
fuse block is located near
the front on the
passenger’s side of the
vehicle. SeeEngine
Compartment Overview on
page 5-12for more
information on location.
Lift the cover to gain access. On some vehicles, there
may be an additional cover that you will need to lift
to gain access to the fuses.
