Care of Safety Belts
Keep belts clean and dry.
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.
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 frequent
appiicaiiorl may ue required. See Fari E. %cur/////e/f&d
Fluids and Lubricants on page 6-24.
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.
Use a car washing soap. Don’t use
strong soaps
or chemical detergents. Be sure to rinse the vehicle
well, removing all soap residue completely. You can get
GM-approved cleaning products from your dealer.
See
GM Vehicle Care/Appearance Materials on
page 5-88. 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.

Use only lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses.
Follow instructions under “Washing Your Vehicle.”

Finish Care
Occasional waxing or mild polishing of your vehicle by
hand may be necessary to remove residue from the
paint finish. You can get GM-approved cleaning products
from your dealer. See
GM Vehicle Care/Appearance
Materials on page
5-88.
If your vehicle has a “basecoatklearcoat” paint finish.
The clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoatklearcoat paint
finish.
Notice: Machine compounding or aggressive
polishing
on a basecoatklearcoat paint finish may
dull the finish or leave swirl marks.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc.,
can damage your vehicle’s finish
if they remain
on painted surfaces. Wash the vehicle as soon as
possible. If necessary, use non-abrasive cleaners that
are marked safe for painted surfaces to remove
foreign matter.
Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their
toll over a
period of years. You can help to keep the paint finish
looking new by keeping your vehicle garaged or covered
whenever possible.
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 a full-strength
glass cleaning liquid. 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.
Aluminum or Chrome-Plated Wheels
Your vehicle may be equipped with either aluminum or
chrome-plated wheels.
Keep your wheels clean using a soft clean cloth with
mild soap and water. Rinse with clean water. After
rinsing thoroughly, dry with a soft clean towel. A wax
may then be applied.
The surface of these wheels is similar
to the painted
surface of your vehicle. Don’t use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,

Removing the Rear Seat Cushion
Notice: The battery and main fuse blocks are
located under the rear seat cushion. The battery’s
ground terminal and some relay wires are exposed.
To help avoid damage to the battery and wires,
be careful when removing or reinstalling the seat
cushion.
Do not remove covers from covered parts.
Do not store anything under the seat, as objects
could touch exposed wires and cause a short.
To remove the rear seat cushion, do the following:

be sure that the safety belts are properly
routed and are not twisted.

Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule to follow:
Follow the Short Trip/City Scheduled Maintenance
if any
one of these conditions is true for your vehicle:
0 Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.
0 Most trips include extensive idling (such as frequent

driving in
stop-and-go traffic).

0 If the vehicle is used for delivery service, police,
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.

Long Trip/Highway Definition
Follow this scheduled maintenance only if none of the
conditions from the Short Trip/City Scheduled
Maintenance are true.
Do not use this schedule if the
vehicle
is used for trailer towing, driven in a dusty area
or used
off paved roads. Use the Short Trip/City
schedule for these conditions
Driving a vehicle with a fully warmed engine under
highway conditions will cause engine oil to break down
slower.
Long Trip/Highway Intervals
Every 7,500 Miles (12 500 km): Engine Oil and Filter
Change (or every 12 months, whichever occurs
first). Tire Rotation.
Every 30,000 Miles (50 000 km): Supercharger Oil
Check (or every 36 months, whichever occurs first)

Be sure to follow the complete scheduled maintenance
on the following pages.
Short Trip/City Scheduled
Maintenance
The services shown in this schedule up to 100,000 miles
(1 66
000 km) should be repeated after 100,000 miles
(166
000 km) at the same intervals for the life of
this vehicle. The services shown at 150,000 miles
(240 000 km) should be repeated at the same interval
after 150,000 miles (240
