When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual
transmission doesn't require changing.
How to Check
Because this operation can be a little difficult. you
rnay choose to have this done at your GM dealership
Service Department.
If you do it yourself. be sure to follow all the
instructions here, or
you could get a false reading.
I NOTICE:
i Too much or too little fluid can damage your
1 transmission. Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure
to get an accurate reading if you check your
transmission fluid.
Check the fluid level only when your engine is off, the
vehicle
is parked on a level place and the transmission is
cool enough for
you to rest your fingers on the
transmission case.
Then. follow these steps:
1. Remove the filler plug.
2. Check that the lubricant level is LIP to the bottom of
the filler plug hole.
3. If the fluid level is good. install the pl~~g md be sure
it is f~llly seated. If the fluid level is low. add more
fluid as described in the next steps.

Here’s how to add fluid. Refer to the Maintenance
Schedule to determine what kind
of fluid to use. See
“Recommended Fluids and Lubricants” in the Index.
I. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid to bring the fluid level
up to the bottom of the
filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch
The hydraulic clutch system in your vehicle is
self-adjusting.
A slight amount of play (1/4 inch to
112 inch or 6 mm to 12 mm) in the pedal is normal.
It isn’t a good idea
to “top off’ your clutch fluid. Adding
fluid won’t correct a leak.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
When to Check and What to Use
Refer to the Maintenance Schedule, Owner Checks and
Services, to determine how often you should check the
fluid level in your clutch master cylinder reservoir and
for the proper fluid. See “Owner Checks and Services”
and “Recommended Fluids and Lubricants” in
the Index.

the reservoir. See the instructions on the reservoir cap.

Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned.
Use a 5060 mix of clean
water and
DEX-COOL@ coolant.
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.
If you have to add coolant more than four times a year,
have
your dealer check your cooling system.
I 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.

Downloaded from www.Manualslib.com manuals search engine When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless
you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then unscrew the cap and
wipe the dipstick with a clean rag. Replace the cap and
completely tighten
it. Then remove the cap again and
look at
the fluid level on the dipstick.
The level should be between the
ADD and FULL marks.
If necessary, add only enough fluid to bring the level up
to the proper range.
What to Use
To determine what kind of fluid to use, see
“Recommended Fluids and Lubricants”
in the Index.
Always use the proper fluid. Failure to use the proper
tluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use.
If you will be
operating your vehicle in an area where the temperature
may
fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid

Downloaded from www.Manualslib.com manuals search engine There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the brake
fluid goes down
to an acceptable level during normal
brake lining wear. When new linings are put
in, the fluid
level goes back up. The other reason is
that fluid is
leaking out of the brake system. If it is, you should have
your brake system fixed, since a leak means that sooner
or later your brakes won’t work well, or won’t work
at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid
won’t correct a leak. If you add fluid
when your linings are worn,
then you’ll have too much
fluid when
you get new brake linings. You should add
(or remove) brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
I A CAUTION:
If you have too much brake fluid, it can spill on the
engine. The fluid
will burn if the engine is hot
enough. You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections” in the Index.
Checking Brake Fluid
I
&-
You can check the brake fluid without taking off the cap.
Just look at the windows
on the brake fluid reservoir.
The fluid levels should be above MIN. If they aren’t,
have your brake system checked
to see if there is a leak.
After work is done
on the brake hydraulic system, make
sure the levels are above
MIN and below the top of
each window.

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.
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 CertificationRire label, which is on the driver’s
door edge, above the door latch, 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:
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
Tire overloading
Bad wear
0 Bad handling
Bad fuel economy.
NOTICE: (Continued)

Downloaded from www.Manualslib.com manuals search engine I NOTICE: (Continued) I
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more. Also. check the
tire pressure
of the spare tire.
If you have a 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.
