Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Poorly maintained and improperly used tires
are dangerous.
Overloading your tires can cause
overheating as a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle” in
the Index.
0 Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended pressure. Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be cut,
punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires
at the recommended pressure.
Worn, old tires can cause accidents. If your
tread
is badly worn, or if your tires have
been damaged, replace them.
Inflation -- Tire Pressure
The CertificatiodTire label, which is on the rear edge of
the driver’s door, shows the correct inflation pressures
for your tires when they’re cold. “Cold” means your
vehicle has been sitting for at least three hours or driven
no more than
1 mile (1.6 km).
NOTICE:
I
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:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
Bad handling
Bad fuel economy.

Downloaded from www.Manualslib.com manuals search engine NOTICE: (Continued)
If your tires have too
much air (overinflation),
you can get the following:
0 Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
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 inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping
out dirt
and moisture.
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 “When It’s Time for New Tires” and
“Wheel Replacement’’ 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 “Scheduled
Maintenance Services” in
the Index for scheduled
rotation intervals.
3
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
Certificationire label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque” in
the Index.
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
“Changing
a Flat Tire” in the Index.) When
It’s Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only
1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any of the following statements
are true:
0 You can see the indicators at three or more places
around the tire.
0 YOU can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
0 The tire has a bump, bulge or split.
0 The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or location
of the damage.

Child Restraint Harness
Keep the safety belts and the built-in child restraint
harness clean and dry.
Do not bleach or dye safety belts or the built-in
child restraint harness. If you do, they may be
severely weakened. In a crash, they might not be
able to provide adequate protection. Clean the
safety belts and the child restraint harness only
with mild soap and lukewarm water.
Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner (GM
Part
No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films on
interior glass.
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.
Cleaning the Outside of the
Windshield, Backglass and
Wiper Blades
If the windshield is not clear after using the windshield
washer, or
if the wiper blade chatters when running, wax,
sap or other material may be on the blade or windshield.
Clean the outside of the windshield
with GM
Windshield Cleaner, Bon Ami@ Powder (non-scratching
glass cleaning powder),
GM Part No. 105001 1. The
windshield
is clean if beads do not form when you rinse
it
with water.
Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by wiping
vigorously
with a cloth soaked in full-strength windshield
washer solvent. Then rinse the blade with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.

Add-on Electrical Equipment
I NOTICE:
Don’t add anything electrical to your vehicle
unless you check with your dealer first. 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” in the Index.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. An electrical overload will cause the
lamps to go on and off, or in some cases to remain off. If
this happens, have your headlamp wiring 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 and
not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel 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 fixed or
goes away.

Downloaded from www.Manualslib.com manuals search engine How This Section is Organized
The remainder of this section is divided into five parts:
“Part
A: Scheduled Maintenance Services” shows
what
to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment,
you should
let your dealer’s service department or another qualified
service cpqter do these
job.
I
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you can
be seriously injured.
Do your own maintenance
work only if you have the required know-how
and the proper
tools and equipment for the job.
If you have any doubt, have a qualified
technician do the work.
If you are skilled enough to do some work
on your
vehicle, you will probably want to get
the service
information. See “Service and Owner Publications”
in the Index. “Part
B: Owner Checks and Services”
tells you what
should be checked and when.
It also explains what you
can easily do to help keep your vehicle in good condition.
“Part
C: Periodic Maintenance Inspections” explains
important inspections that your dealer’s service department
or another qualified service center should perform.
“Part
D: Recommended Fluids and Lubricants’’ lists
some recommended products
to help keep your vehicle
properly maintained. These products, or their
equivalents, should be used whether you do the work
yourself or have it done.
“Part
E: Maintenance Record” provides a place for
you to record the maintenance performed on your
vehicle. Whenever any maintenance is performed, be
sure to write
it down in this part. This will help you
determine when your next maintenance should be done.
In addition,
it is a good idea to keep your maintenance
receipts. They may be needed
to qualify your vehicle for
warranty repairs.
