Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service, see
your Catera Warranty booklet for details. 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 about and a serious accident. See
‘Zoading Your Vehicle’’ in the Index.
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.
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.
See “Inflation
-- Tire Pressure’’ in this section
for inflation pressure adjustment for higher
speed driving.
Overinflated tires are more likely to be

Downloaded from www.Manualslib.com manuals search engine When to Check
Check your tires once a month or more. Also, check the
tire pressure of the spare tire.
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 at 5,000 miles (8 000 km) and
then every
10,000 miles (16 000 km) thereafter. 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 Maintenance Schedule
booklet for scheduled rotation intervals.
7-
When rotating your tires, always use the correct rotation
pattern shown here.

Downloaded from www.Manualslib.com manuals search engine After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that all wheel bolts are
properly tightened. See “Wheel Bolt Torque” in
the Index.
Rust or dirt on a wheel, or on the parts to which
it
is fastened, can make wheel studs 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:
You can see the indicators at three or more places
around the tire.
0 YOU can see cord or fabric showing though the
tire’s rubber.
0 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.

Windshield 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. 1050011. The
windshield is clean
if beads do not form when you rinse
it with water.

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.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply silicone
grease with a clean cloth at least every
six months. During
very cold, damp weather more fiquent application may be
required.
(See “Recommended Fluids and Lubricants” in
the Maintenance Schedule booklet.)
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
The ‘best way to preserve your vehicle’s finish is to keep it
clean by washing
it often with lukewarm or cold water.
Don’t wash your vehicle in the direct rays of the sun.
Don’t use strong soaps or chemical detergents. Use
liquid hand, dish or car washing (mild detergent) soaps.
You can get GM-approved cleaning products from your
dealer. (See “Appearance Care and Materials” in the
Index.) Don’t use cleaning agents that are petroleum
based, or that contain acid or abrasives. All cleaning
agents should be flushed promptly and not allowed to
dry on the surface, or they could stain. Dry the finish
with a soft, clean chamois or an all-cotton towel to
avoid surface scratches and water spotting.
High pressure car washes may cause water to enter
your vehicle.
Cleaning Exterior LampsLenses
Use lukewarm or cold water, a soft cloth and a liquid
hand, dish or car washing
(mild detergent) soap to clean
exterior lamps and lenses. Follow instructions under
“Washing Your Vehicle.”

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.
Headlamp Wiring
The headlamp wiring has several fuses which are
powered by a MaxiFuse@. An electrical overload will
cause the lamps to go on and off, or in some cases to
remain
off. If this happens, have the headlamp wiring
checked right away.
MaxiFuse is a registered trademark of Little Fuse
Incorporated.
Windshield Wiper Fuses
If the windshield wiper motor overheats due to heavy
snow, etc., the wipers will stop until the motor cools. If
the overload is caused by some electrical problem, be
sure to have it fixed.
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.
Power Windows and Other Power Options
Circuit breakers 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.
