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, cha ng, etc. Inspect
drum brake linings for wear or cracks. Inspect disc brake
pads for wear and rotors for surface condition. Inspect
other brake parts, including drums, wheel cylinders,
calipers, parking brake, etc. Check parking
brake adjustment.(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,
cha ng, etc. Visually check constant velocity joints,
rubber boots and axle seals for leaks.
(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.
