in the center and on
the sides of your
instrument panel.
You can move the vents to direct the flow
of air, or close the vents
altogether. When you close a vent, it will increase the flow of air coming out
of any vents that are open.
If your vehicle doesn’t have air conditioning, there is an air vent in the
passenger-side kick panel below the instrument panel. The vent has a
handle to open and close it.

If you get the overheat warning but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
See “Driving on Grades”
in the Index.
If
you get the overheat warning with no sign of steam, try this for a minute
or

1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan speed and open the

If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower
for about ten minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your vehicle right away.
If there’s still no sign
of steam, push the accelerator until the engine speed is
about twice
as fast as normal idle speed. Bring the engine speed back to
normal idle speed after two or three minutes. Now see
if the warning stops.
But then, if you still have the warning, turn @‘the engine and get everyone
out of the vehicle until it cools down.
You may decide not to lift the hood but to get service help right away.

lower.
If the level is lower, add more of the proper mix through the
filler neck until the level reaches the base
of the filler neck.
8. Then replace the pressure cap. At any time during this procedure if
coolant begins to flow out of the filler neck, reinstall the pressure cap.
Be sure the arrows on the pressure cap line

Engine Fan Noise
This vehicle has a clutched engine cooling fan. When the clutch is engaged,
the fan spins faster to provide more air to cool the engine. In most every day
driving conditions the clutch is not fully engaged. This improves fuel
economy and reduces fan noise. Under heavy vehicle loading, trailer towing
and/or high outside temperatures, the fan speed increases when the clutch
engages.
So you may hear an increase in fan noise. This is normal and
should not be mistaken
as the transmission slipping or making extra sh

You may
also hear this fan noise when you start the engine. It will go away
as the fan clutch disengages.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving, especially if you
maintain your tires properly.
If air goes out of a tire, it’s much more likely to
leak out slowly. But if you should ever have a “blowout,” here are a few tips
about what
to expect and what to do:
If
a front tire fails, the flat tire will create a drag that pulls the vehicle
toward that side. Take your foot off the accelerator pedal and grip the
steering wheel firmly. Steer
to maintain lane position, then gently brake to a
stop well out of the traffic lane.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you use an improper coolant mix, your engine could overheat
and be badly damaged. The repair cost wouldn’t be covered by
your warranty.
Too much water in the mix can freeze and crack
the engine, radiator, heater core and other parts.
Some conditions, such as air trapped in the cooling system, can affect the
coolant level in the radiator. Check the coolant level when the engine is cold
and follow the steps under “Adding Coolant” for the proper way to add
coolant.
If you have to add coolant more than four times a year, have your dealer
check your cooling system.
NOTICE:
If YOU use the proper coolant, you don’t have to add extra
inhibitors or additives which claim to improve the system. These
can be harmful.

Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched
warning sound when the brake pads are worn and new pads are needed. The
sound may come and go or be heard all the time your vehicle is moving
(except when you are pushing
on the brake pedal firmly).
NOTICE:
Continuing to drive with worn-out brake pads could result in
costly brake repair.
Some driving conditions or climates may cause a brake squeal when the
brakes are first applied or lightly applied. This does not mean something is
wrong with your brakes.
Your rear drum brakes don’t have wear indicators, but
if you ever hear a
rear brake rubbing noise, have the rear brake linings inspected. Also,
the
rear brake drums should be removed and inspected each time the tires are
removed for rotation or changing. When you have the front brakes replaced,
have
the rear brakes inspected, too.
Brake linings should always be replaced
as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to normal height, or if
there is a rapid increase in pedal travel. This could be a sign of brake
trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes adjust for wear.
If your brake pedal goes down Farther than normal, your rear drum brakes
may need adjustment. Adjust them by backing
up and firmly applying the
brakes a few times.

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.

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.

which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
Warning:
The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination, can cause heat
buildup and possible tire failure.
These grades are molded on the sidewalls of passenger car tires.
While the tires available as standard or optional equipment
on General
Motors vehicles may vary with respect to these grades, all such tires meet
General Motors performance standards and have been approved for use on
General Motors vehicles. All passenger type
(P Metric) tires must conform
to Federal safety requirements in addition
to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced carefully at the
factory
to give you the longest tire life and best overall performance.
In most cases, you will
not need to have your wheels aligned again.
However, if
you notice unusual tire wear or your vehicle pulling one way or
the other, the alignment may need to be reset.
If you notice your vehicle
vibrating when driving on a smooth road, your wheels may need
to be
rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted or corroded. If
wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts
should be replaced. If the wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your GM dealer if any of
these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have the same load carrying capacity, diameter,
width, offset, and
be mounted the same way as the one it replaces.
