How To Check Power Steering Fluid
When the engine compartment is cool, 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 at the FULL
COLD mark. Add enough fluid to bring
the level up to the mark.
A fluid loss in this system could indicate a problem. Have the system
inspected and repaired.
What to Add
Refer to the Maintenance Schedule to determine what kind of fluid to use.
See “Recommended Fluids and Lubricants” in the Index.
NOTICE:
When adding power steering fluid or making a complete fluid
change, always use the proper fluid. Failure to use the proper\

fluid can cause leaks and damage hoses and seals.

Brake Master Cylinder
Your brake master cylinder is here. It is filled with DOT-3 brake fluid.
There are only two reasons why the brake fluid level in your master cylinder
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.
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.

Downloaded from www.Manualslib.com manuals search engine Air Conditioning
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.

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.

KEEP ENGINE OIL
AT THE PROPER
LEVEL AND CHANGE
AS RECOMMENDED
Section
This section covers the maintenance required for your vehicle. Your vehicle
needs these services to retain its safety, dependability and emission control
performance.
Protection I
Have you purchased the GM Protection Plan? The Plan supplements your
new vehicle warranties. See your GM dealer for details.
Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your vehicle in good
working condition, but also helps the environment.
All recommended
maintenance procedures are important. Improper vehicle maintenance or the
removal of important components can significantly affect the quality of the
air we breathe. Improper fluid levels or even the wrong tire inflation can
increase the level
of emissions from your vehicle. To help protect our
environment, and
to help keep your vehicle in good condition, please
maintain your vehicle properly.

Downloaded from www.Manualslib.com manuals search engine How This Section is Organized
The remainder of this section is divided into five parts:
“Part A: Scheduled Maintenance Services” shows what to have done and
how often. Some of
these services can be complex, so unless you are
technically qualified and have the necessary equipment,
you should let your
dealer’s service department or another qualified service center do
these jobs.
If
you are skilled enough to do some work on your vehicle, you will
probably want to get the service information
GM publishes. See “Service
Publications”
in the Index.
“Part B: Owner Checks and Services” tells you what should be checked
whenever you stop for fuel. It also explains what
you can easily do to help
keep your
vehicle in good condition.
“Part C: Periodic Maintenance Inspections” explains important
inspections that your
GM dealer’s service department or another qualified
service center should perform.
“Part D: Recommended Fluids and Lubricants” lists some products GM
recommends to help keep your vehicle properly maintained. These products,
or their equivalents, should be used whether you do the work yourself or
have
it done.
“Part E: Maintenance Record” provides a place for you to record the
maintenance performed on your vehicle. Whenever any maintenance is
performed, be sure
to write it down in this part. This will help you
determine when your next maintenance should be done. In addition,
it is a
good idea to keep your maintenance receipts. They may be needed to
qualify your vehicle for warranty repairs.

Using Your Maintenance Schedule
We at General Motors want to help you keep your vehicle in good working
condition. But we don’t know exactly how you’ll drive it.
You may drive
very short distances only
a few times a week. Or you may drive long
distances all the time
in very hot, dusty weather. You may use your vehicle
in making deliveries.
Or you may drive it to work, to do errands or in many
other ways.
Because
of all the different iYi@ people use their GM vehicles, maintenance
needs vary. You may even need more frequent checks and replacements than
you’ll find in the schedules in this section.
So please read this section and
note how you drive. If you have any questions on how to keep your
vehicle
in good condition, see your GM dealer.
This part tells you the maintenance services you should have done and when
you should schedule them. If you go to your dealer for your service needs,
you’ll know that GM-trained and supported service people will perform the
work using genuine GM parts.
The proper fluids and lubricants to use are listed
in Part D. Make sure
whoever services your vehicle uses these. All parts should be replaced
and
all necessary repairs done before you or anyone else drives the vehicle.
These schedules are for vehicles that:
carry passengers and cargo within recommended limits. You will find
these limits on your vehicle’s CertificatiodTire label. See “Loading
Your Vehicle’’
in the Index.
are driven on reasonable road surfaces within legal driving limits.
use the recommended unleaded fuel. See “Fuel’’ in the Index.
Selecting the Right Schedu/e
First you’ll need to decide which of the two schedules is right for your
vehicle. Here’s how to decide which schedule
