Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind
of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care’’ in
the Index.
Brake Wear
Your vehicle has four-wheel disc 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).
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.

Plan
Have you purchased the GM Protection Plan? The Plan
supplements
your new vehicle warranties. See your
Warranty and Owner Assistance booklet, or your
Pontiac 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 can even
affect
the quality of the air we breathe. Improper fluid
levels or the wrong tire inflation
can increase the level
of emissions from your vehicle.
To help protect our
environment, and
to keep your vehicle in good
condition, please maindn your vehicle properly.
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.

Maintenance Schedule
The services shown in this schedule up to 100,000 miles
(166
OOO km) should be performed after 100,000 miles
(166
000 km) at the same intervals. The services shown
at
150,000 miles (240 000 km) should be performed at
the same interval after 150,000 miles
(240 000 km).
See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.
Footnotes
? The US. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform
this maintenance item will not nullify
the emission warranty or limit recall liability prior
to the
completion
of the vehicle’s useful life. We, however,
urge that
all recommended maintenance services be
performed at the indicated intervals and the maintenance be recorded.
* Your vehicle has an Engine Oil Life Monitor. This
monitor will show you when to change the engine oil
and filter
-- usually between 3,000 miles (5 OOO km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come
on
before 3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
without
an oil and filter change.
The system won’t detect dust
in the oil. So if you drive
in
a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner if the CHANGE
OIL SOON light comes on. Remember to reset the
Oil Life Monitor when the oil has been changed. For
more information, see “CHANGE
OIL SOON light”
in the Index.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspections”
in Part C of this schedule.
