The U.S. 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.
# Lubricate the steering and shift linkage.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspection” in Part C of this schedule.
++ If you drive in a highly corrosive environment, your

/d, CAUTION:
m I-
When you are doing this check, the vehicle could
move suddenly. If it does, you
or others could be
injured. Follow the steps below.
1. Before you start, be sure you have enough room
2. Firmly apply both the parking brake (see “Parking around the vehicle.
Brake” in the Index if necessary) and the regular brake.
NOTE:
Do not use the accelerator pedal, and be
ready to turn off the engine immediately if it starts.
3. On automatic transmission vehicles, try to start the
engine in each gear. The starter should work
only in
PARK
(P) or NEUTRAL (N). If the starter works in
any other position, your vehicle needs service.
On manual transmission vehicles, put the shift lever
in NEUTRAL (N), push the clutch down halfway
and try to start the engine. The starter should work
only when the clutch is pushed down all the way to
the floor. If the starter works when the clutch isn’t
pushed all the way down, your vehicle needs service.

When you are doing this check, the vehicle could
move suddenly. If it does, you
or others could be
injured. Follow the steps below.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a
level surface.
2. Firmly apply the parking brake (see “Parking Brake’
in the Index if necessary).
NOTE: Be ready to apply the regular brake
immediately if the vehicle begins to
move.
3. With the engine off, turn the key to the RUN
position, but don’t start
the engine. Without applying
the regular brake, try
to move the shift lever out of
PARK (P) with normal effort. If the shift lever
moves out of PARK (P), your vehicle’s BTSI
needs service.

Downloaded from www.Manualslib.com manuals search engine Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc. The
parking brake is self-adjusting and no manual
adjustment is required.
You may need to have your
brakes inspected more often if your driving habits or
conditions result
in frequent braking.
CaliperKnuckle Maintenance Inspection
If you operate your vehicle in a highly corrosive
environment, as indicated by the shaded areas on the
map following this text, your vehicle may require
additional brake service. Refer to the appropriate
GM Service Bulletin for the proper front caliper
inspection procedure. As necessary, front caliper pins
and knuckle brake pad abutments should be lubricated
at every other tire rotation.
Also, see your GM dealer’s
service department or qualified service center for
additional information.
