2005 PONTIAC BONNEVILLE check engine 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 airbag coverings,
and have them repaired or replaced. (The airbag 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
Windshield and Wiper Blades on page 5-106.
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 6-25.
Automatic Transaxle Check
Check the transaxle uid level; add if needed. See
Automatic Transaxle Fluid (3.8L V6 Engine) on
page 5-25orAutomatic Transaxle Fluid (4.6L V8
Engine) on page 5-28. A uid loss may indicate a
problem. Check the system and repair if needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specied in Part D.
Body Lubrication Service
Lubricate all hinges and latches, including those for the
hood, rear compartment, glove box door, console
door and any folding seat hardware. Part D tells you
what to use. More frequent lubrication may be required
when exposed to a corrosive environment.
