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 blade inserts 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 air bag
coverings, and have them repaired or replaced. (The air
bag system does not need regular maintenance.)
(f)Lubricate all key lock cylinders. Lubricate all body
door hinges. Lubricate all hinges and latches, including
those for the hood, rear compartment, console door
and any folding seat hardware. 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.
6-8

(h)Change automatic transmission 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 high performance operation.
If you do not use your vehicle under any of these
conditions, the uid and lter do not require changing.
(i)Drain, ush and rell cooling system. See Engine
Coolant on page 5-29for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap and ller neck.
Pressure test the cooling system and pressure cap.
(j)Replace the belt (or every 96 months, whichever
occurs rst). Failure to follow the maintenance described
may result in a broken timing belt and could cause
severe engine damage. It is important to use only
genuine GM parts when replacing the timing belt.
(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)Change uid if the vehicle is used for high
performance operation.
(m)Change uid whenever the vehicle has been driven
for 3,000 miles (5 000 km) with the transmission
temperature at 290°F (143°C) or higher without using
an auxiliary uid cooler. See Message Center (CTS-V)
on page 3-53andTransmission Fluid Hot Message
on page 3-57.
Owner Checks and Services
These owner checks and services should be performed
at the intervals specied to help ensure the safety,
dependability and emission control performance of your
vehicle. Your GM Goodwrench dealer can assist you
with these checks and services.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
inRecommended Fluids and Lubricants on page 6-13.
