At Least Twice a Year At Least Once a Year
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.
Automatic Transmission Check
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.
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part D.
Body Lubrication Service
Lubricate all fuel door, body hood and body door
hinges, rear compartment hinges, tailgate handle pivot
points, latches, locks and folding seat hardware. Part
D
tells you what to use. More frequent lubrication may be
required when exposed to a corrosive environment.
Ccv-ter Switch Check
