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.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn or damaged
or that streak or
miss areas of the windshield. Also see “Wiper Blades,
Cleaning” in the Index.
Automatic Transaxle Check
Check the transaxle fluid level; add if needed. See
“Automatic Transaxle” in the Index.
A fluid loss
may indicate a problem. Check the system and repair
if needed.
At Least Once a Year

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 retailer’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.
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. Inspect other brake parts,
including calipers, parking brake, etc. You may need to
have your brakes inspected more often if your driving
habits or conditions result
in frequent braking.
