Automatic Transmission Check
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. Look
for any other loose or damaged
safety belt system parts.
If you see anything that might
keep a safety belt system from doing its job, have
it
repaired. Have any torn or frayed safety belts replaced.
Also
look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag
system
does not need regular maintenance.)
Air Cleaner Filter Restriction Indicator Check
Your vehicle has an indicator on the engine that lets you
know when the air cleaner filter is dirty and needs to be
changed. Check indicator at least twice
a year or when
your
oil is changed. See “Air Cleaner” in the Index for
more information.
Manual Transmission Check
Check the transmission fluid level; add if needed. See
“Manual Transmission” in
the Index. A fluid loss may
indicate
a problem. Check the system and repair if needed. Check the transmission
fluid level; add if needed. See
“Automatic Transmission”
in the Index. A fluid loss
may indicate a problem. Check the system and repair
if needed.
Hydraulic Clutch System Check
Check the fluid level in the clutch reservoir. See
“Hydraulic Clutch Fluid”
in the Index. A fluid loss in
this system could indicate a problem. Have the system
inspected and repaired
at once.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified
in Part D.
Body Lubrication Service
Lubricate all fuel doors, body hood and body door

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.

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 and Suspension 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.
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.

Drive Axle Service
Check readfront axle fluid level and add its needed.
Check constant velocity joints and axle seals for leaking.
Transfer Case (Four-wheel Drive)
Inspection
Every 12 months or at oil change intervals, check front
axle and transfer case and add lubricant
when necessary.
Oil
the control lever pivot point and all exposed control
linkage. Check
vent hose at transfer case for kinks and
proper installation. More frequent lubrication
may be
required
on off-road use.
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. For vehicles with rear drum
brakes, 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.
