automatic or manual transmission fluid levels and add as
needed. See “Transfer Case,” “Axle, Rear,”
“Axle, Front” and “Automatic Transmission” or
“Manual Transmission”
in the Index. Check for leaks.
A fluid loss in these systems could indicate a problem.

(Automatic Transmission)
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.
2.
3.
Before you start, be sure you have enough room
around the vehicle.
Firmly apply both the parking brake (see “Parking 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.
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

of your vehicle in case
it begins to roll. Be ready to apply the regular
brake at once should the vehicle begin to move.
Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot
on the regular brake, set the
parking brake.
To check the parking brake's holding ability:
With the engine running and transmission in
NEUTRAL
(N), slowly remove foot pressure from
the regular brake pedal.
Do this until the vehicle is
held by the parking brake only.
To check the PARK (P) mechanism's holding ability:

Part C: Periodic Maintenance
Inspections
Listed below are inspections and services which should
be performed at least twice a year (for instance, each spring and fall). You should let your
GM dealer’s
service department or other qualified service center do
these
jobs. Make sure any necessary repairs are
completed at once.
Proper procedures to perform these services may be
found in a
GM service manual. See “Service and Owner
Publications” in the Index.
Steering, Suspension and Front Drive Axle
Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose
or missing parts, signs of
wear
or lack of lubrication. Inspect the power steering
lines and hoses
for proper hook-up, binding, leaks,
cracks, chafing,
etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look
for broken, damaged,
missing or out-of-position parts as well
as open seams,
holes, loose connections or other conditions which could
cause a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See “Engine Exhaust” in
the Index.
Radiator and Heater Hose Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen
or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed.

Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and for damage or missing parts. Replace parts as
needed. Replace any cables that have high effort or
excessive wear.
Do not lubricate accelerator and cruise
control cables.
Rear Axle (All) and Front Axle
(Four-wheel Drive) Service
Check the gear lubricant level and add if needed. See
“Rear Axle” and “Four-wheel Drive” in
the Index. A
fluid loss may indicate a problem. Check the system(s),
and repair the system(s) if needed. Refer to “Scheduled
Maintenance Services,” earlier
in this section, to
determine when to change the lubricant.
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.
Check parking brake adjustment. You may need to have
your brakes inspected more often if your driving habits
or conditions result in frequent braking.
Clutch System Service
Check clutch pedal free travel and adjust as necessary.
See “Clutch Adjustment’’ in the Index.
