2004 CHEVROLET OPTRA brake light

At Least Twice 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 coverings,
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
Cleaning the Outside of Your Vehicle on page 5-76.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. SeePart D: Recommended Fluids and
Lubricants on page 6-24.
Automatic Transaxle Check
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss.
Check for leaks. If a leak occurs, take the vehicle to your
dealer and have it repaired as soon as possible.
Manual Transaxle Check
It is not necessary to check the transaxle fluid level.
Check for leaks. A fluid leak is the only reason for fluid
loss. Have the system inspected and repaired if needed.
Clutch and Brake Pedal Free Play
Check
Check the clutch pedal and brake pedal for free play
and adjust as necessary.
