Maintenance Footnotes
†The U.S. Environmental Protection Agency or
the California Air Resources Board has determined
that the failure to perform this maintenance item
will not nullify the emission warranty or limit
recall liability prior to the completion of the
vehicle’s useful life. We, however, urge that all
recommended maintenance services be performed
at the indicated intervals and the maintenance
be recorded.
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang,
etc. Inspect disc brake pads for wear and rotors for
surface condition. Inspect other brake parts,
including calipers, parking brake, etc.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts or signs of wear. Inspect power steering lines
and hoses for proper hook-up, binding, leaks,
cracks, chang, etc.(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings and clamps; replace with
genuine GM parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.
(d)Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn
or damaged or that streak or miss areas of
the windshield.
(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 lter may require replacement more often.
(h)Change automatic transaxle uid and lter 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 found in taxi, police, or delivery
service.(j)Drain, ush, and rell cooling system. This
service can be complex; you should have
your dealer perform this service. See Engine
Coolant on page 347 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and ller neck. Pressure test the cooling
system and pressure cap.
(k)A uid loss in any vehicle system could
indicate a problem. Have the system inspected
and repaired and the uid level checked. Add uid
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 lter at each engine oil change.
(n)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
