Engine Air Cleaner/Filter
The engine air cleaner/filter is located on the driver's
side of the engine. Be sure the engine has cooled before
following these steps to replace the air cleaner filter:
For more information on location, see ªEngine
Compartment Overviewº in the Index.
1. Loosen both wing screws on the top of the engine air
cleaner/filter assembly.2. Lift up the outboard side of the engine air
cleaner/filter cover at an angle while pulling toward
you. This is necessary due to the three tabs located
on the rear of the engine air cleaner/filter cover.
3. Remove the engine air cleaner/filter element and any
loose debris that may be found lying in the air
cleaner base.
4. Replace the air filter element.

6-33 Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top
-quality GM brake
parts. When you replace parts of your braking
system
-- for example, when your brake linings wear
down and you have to have new ones put in
-- be sure
you get new approved GM replacement parts. If you
don't, your brakes may no longer work properly. For
example, if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change
-- for the worse. The braking
performance you've come to expect can change in many
other ways if someone puts in the wrong replacement
brake parts.
Battery
Your new vehicle comes with a maintenance free
ACDelco
battery. When it's time for a new battery, get
one that has the replacement number shown on the original
battery's label. We recommend an ACDelco battery.
WARNING: Battery posts, terminals and related
accessories contain lead and lead compounds, chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.The battery is located under the rear seat cushion.
To access the battery, see ªRemoving the Rear Seat
Cushionº in the Index. You don't need to access the
battery to jump start your vehicle. See ªJump Startingº
in the Index.
CAUTION:
A battery that isn't properly vented can let
sulfuric acid fumes into the area under the rear
seat cushion. These fumes can damage your rear
seat safety belt systems. You may not be able to
see this damage, and the safety belts might not
provide the protection needed in a crash. If a
replacement battery is ever needed, it must be
vented in the same manner as the original
battery. Always make sure that the vent hose
is properly reattached before reinstalling the
seat cushion.

6-47 Inflation -- Tire Pressure
The Tire-Loading Information label, which is located on
the rear edge of the driver's side rear door, shows the
correct inflation pressures for your tires when they're
cold. ªColdº means your vehicle has been sitting for at
least three hours or driven no more than 1 mile (1.6 km).
If you'll be driving at high speeds (e.g., speeds of
100 mph (160 km/h) or higher), where it is legal, set the
cold inflation pressure to the maximum inflation pressure
shown on the tire sidewall, or to 38 psi (265 kPa),
whichever is lower. See the example below. When you
end this high
-speed driving, return to the cold inflation
pressure shown on the Tire
-Loading Information label.
Example:
You'll find maximum load and inflation pressure
molded on the tire's sidewall, in small letters, near the
rim flange. It will read something like this: Maximum
load 690 kg (1521 lbs.) @ 300 kPa (44 psi) Max. Press.
For this example, you would set the inflation pressure
for high
-speed driving at 38 psi (265 kPa).
NOTICE:
Don't let anyone tell you that underinflation or
overinflation is all right. It's not. If your tires
don't have enough air (underinflation), you can
get the following:

Too much flexing

Too much heat

Tire overloading

Bad wear

Bad handling

Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:

Unusual wear

Bad handling

Rough ride

Needless damage from road hazards.

6-49
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
If the TPM system detects low tire pressure, below
24 psi (165 kPa), or high tire pressure, above 36 psi
(248 kPa), a message, CHECK TIRE PRESSURE, will
appear on the Driver Information Center (DIC) display.
By pressing the INFO button, the DIC screen will show
which tire(s) has the low or high pressure condition.
See ªInflation
-- Tire Pressureº in the Index for
information regarding correct tire inflation. If a tire is
low, you should stop as soon as possible and check all
your tires for damage. If a tire is flat, see ªIf a Tire
Goes Flatº in the Index.
NOTICE:
Do not use a tire sealant if your vehicle is equipped
with Tire Pressure Monitors. The liquid sealant
can damage the tire pressure monitor sensors.
Once a low or high tire pressure condition is detected,
the TPM system will display the CHECK TIRE
MESSAGE each time the engine is started, until the
tire(s) are set to the correct inflation pressure. The Certification/Tire Label, which is located on the
rear edge of the driver's side rear door, shows the
correct inflation pressure for the tires on your vehicle.
The TPM system also allows the driver to check the
air pressure status of each road tire using the Driver
Information Center (DIC). Each tire's air pressure will be
listed individually, in the following order: LF (left front
or driver's side front tire), RF (right front or passenger's
side front tire), RR (right rear or passenger's side
rear tire) and LR (left rear or driver's side rear tire).
See ªInflation
-- Tire Pressureº in the Index for
information regarding correct tire inflation. Also, see
ªDriver Information Center (DIC)º in the Index for
information on the DIC controls and displays.
If the DIC display doesn't show tire pressures or the
SERVICE TPM SYSTEM message appears, see your
dealer for service. The TPM system may not work
properly while the compact spare tire is installed.
Anytime you replace one or more tires or rotate your
tires the TPM system will need to be reset. A special
tool is needed to reset the sensor identification codes.
See your dealer for service.
The TPM system can alert you about a low or high
tire pressure condition, but it doesn't replace normal
tire maintenance. See ªTiresº in the Index.

6-50 Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See ªWhen It's Time for New Tiresº and
ªWheel Replacementº later in this section for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See ªScheduled
Maintenance Servicesº in the Maintenance Schedule
booklet for scheduled rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.Don't include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire
-Loading
Information label. Vehicles equipped with the Tire
Pressure Monitor (TPM) system will need to have the
sensors reset after a tire rotation is performed. A special
tool is needed to reset the sensor identification codes.
See your dealer for service. Make certain that all wheel
nuts are properly tightened. See ªWheel Nut Torqueº
in the Index.
CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make 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 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.
See ªChanging a Flat Tireº in the Index.

6-59 Cleaning Wood Panels
Use a clean cloth moistened in warm, soapy water (use
mild dish washing soap). Dry the wood immediately
with a clean cloth.
Cleaning Speaker Covers
Vacuum around a speaker cover gently, so that the
speaker won't be damaged. Clean spots with just water
and mild soap.
Care of Safety Belts
Keep belts clean and dry.
CAUTION:
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash, they
might not be able to provide adequate protection.
Clean safety belts only with mild soap and
lukewarm water.
Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner or
a liquid household glass cleaner will remove normal
tobacco smoke and dust films on interior glass.
See ªAppearance Care and Materialsº in the Index.
Don't use abrasive cleaners on glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped off later.
If abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across
the defogger grid.

6-67 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 fires 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. If a MaxiFuse

should blow, see your dealer
for service immediately.
If you ever have a problem on the road and don't have a
spare fuse, you can ªborrowº one that has the same
amperage. Pick some feature of your vehicle that you
can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
The MaxiFuses are located in two Bussed Electrical
Centers (BEC), 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 Bussed Electrical CenterThe Engine Compartment Bussed Electrical Center
(BEC) is located next to the engine on the passenger's
side of the vehicle. For more information on location,
see ªEngine Compartment Overviewº in the Index.
To access the fuse block, push in the two tabs located on
the top and the bottom of the fuse block cover.
Fuse 22 or 23 can be moved to the outer position to
enable the accessory power outlets or cigarette lighter
when the ignition is not on. See your dealer for
additional assistance, if needed.
