Cadillac 2006 STS - Manual (Page 438)

(e) 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.
(f) Lubricate all key lock cylinders. Lubricate all
hinges and latches, including those for the hood, rear
compartment, glove box door, and console door.
More frequent lubrication may be required when
exposed to a corrosive environment. Applying silicone
grease on weatherstrips with a clean cloth will make
them last longer, seal better, and not stick or squeak.
(g) If you drive regularly under dusty conditions, the filter
may require replacement more often.
(h) Change automatic transmission fluid and filter if
the vehicle is mainly driven under one or more of
these conditions:
− In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
− In hilly or mountainous terrain.
− When doing frequent trailer towing.
− Uses such as limousine service.
− Uses such as high performance operation.
(j) Drain, flush, and refill cooling system. This service
can be complex; you should have your dealer perform
this service. See Engine Coolant on page 5-27 for
what to use. Inspect hoses. Clean radiator, condenser,
pressure cap, and filler neck. Pressure test the
cooling system and pressure cap.
(k) A fluid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the fluid level checked. Add fluid if needed.
(l) Inspect throttle body bore and valve plates for
deposits. Open the throttle valve and inspect all
surfaces. Clean as required.
(m) If you drive regularly under dusty conditions, inspect
the filter at each engine oil change.
(n) Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.
