Fluid Leak Check
After the vehicle has been parked for awhile, inspect the surface beneath the
vehicle for water, oil,
fuel or other fluids. Water dripping from the air
conditioning system is normal. If you notice fuel leaks or fumes, the causes
should be found and corrected at once.
Bulb Replacement
Before replacing any bulbs, make sure all lights are off and the vehicle is
not running.
Sealed Beam Headlamps
1. Open the hood.
2. Remove the four
screws from the
headlamp bezel.
Pull the bezel out
so you can see
the parkingkurn
signal sockets.
3. Press the tab and turn the socket counterclockwise to remove the socket
from the bezel. If the socket does
not have a tab, turn the socket
counterclockwise. Set the bezel aside.
4. Remove the four retainer screws and the retainer.

Every now and then have your dealership check your air conditioning
system
to be sure it has not lost any cooling ability. If you think the system
is not working properly, have your dealership check it out as soon as
possible.
The air conditioning will not work when the temperature
is below 40°F
(4°C).
Lock Cylinders
To be sure your locks operate properly, they must be lubricated.
Refer
to the Maintenance Schedule to determine how often to lubricate them
and what type
of lubricant to use.
You should not use penetrating oils because they could wash out the factory
installed lubricant and cause the lock to bind. De-icers which contain
alcohol could also wash away the lubricant,
so be sure to lubricate the lock
after using a de-icer of this type.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle if you notice:
0 Engine misfiring
Loss of performance
Exhaust system components hanging lower than normal.
Loud exhaust system noises.
Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three-way Catalytic Converter
Your vehicle’s three-way catalytic converter is designed to reduce the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If you use leaded fuel, you could damage your three-way catalytic converter
and other engine components.
Engine Control Module System
This system has an oxygen (02) sensor that helps keep your engine’s
air-fuel mixture at a proper level. Use only unleaded fuel in your vehicle. If
you
use leaded fuel, you could damage your oxygen (02) sensor and affect
your vehicle’s emissions.

Downloaded from www.Manualslib.com manuals search engine lnflation - 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 a mile.
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:
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:
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. Simply looking
at the tires will not tell you the pressure, especially if you have radial tires
- which may look properly inflated even if they’re underinflated.
If your tires
have valve caps, be sure to put them back on. They help prevent
leaks by keeping
out dirt and moisture.

Downloaded from www.Manualslib.com manuals search engine Tire lnspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles ( 10 000 to 13 000 km)
for any signs of unusual wear. If unusual wear
is present, 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.
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 Certification/Tire label. Make certain that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” in the Index.

Downloaded from www.Manualslib.com manuals search engine When It’s Time for New Tires
Tread Wear
Indicators
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:
You can see the indicators at three or more places around the tire.
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.
The tire has a bump, bulge or split.
The tire has a puncture, cut, or other damage that can’t be repaired well
because of the size or location of
the damage.
Buying New Tires
To find out what kind and size of tires you need, look at the
CertificatiodTire label.
The tires installed on
your vehicle when it was new had a Tire Performance
Criteria Specification (TPC Spec) number on each tire’s sidewall. When
you
get new tires, get ones with that same TPC Spec number. That way, your
vehicle will continue to have tires that are designed to give proper
endurance, handling, speed rating, traction, ride and other things during
normal service
on your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by an
“MS” (for mud and snow).
If you ever replace your tires with those not having a TPC Spec number,
make sure they are the same size, load range, speed rating and construction
type (bias, bias-belted or radial) as your original tires.

Keep belts clean and dry.
Glass
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.
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
or other material may be on the
blade or windshield.
Clean the outside
of the windshield with GM Windshield Cleaner, Bon-Ami
Powder@ (GM Part
No. 105001 1). The windshield is clean if beads do not
form when you rinse it with water.
Clean the blade by wiping vigorously with a cloth soaked in full strength
windshield washer solvent. Then rinse the blade with water.
Wiper blades should be checked on a regular basis and replaced when 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 frequent application may
be required. (See “Recommended Fluids
& Lubricants’’ in the Index.)

Downloaded from www.Manualslib.com manuals search engine Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from short circuits by a
combination of fuses, circuit breakers, and fusible thermal links in
the
wiring itself. This greatly reduces the chance of fires caused by electrical
problems.
See “Fuses and Circuit Breakers” in the Index for more
information.
Headlamps
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 Wipers
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.
Trailer Wiring Harness
The optional eight-wire trailer wiring harness is protected by an in-line fuse
in the battery feed wire. This fuse is near the junction block, See “Trailer
Wiring Harness” in the Index.
