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
Windshield and Wiper Blades on page 5-78.
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. See Part 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
