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.
@Whenever the tires are rotated, the Check Tire
Pressure System (if equipped) must be reset.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-14.
Engine Oil Scheduled Maintenance
Change engine oil and filter as indicated by the GM
Oil Life System (or every 12 months, whichever
occurs first). Reset the system.
Your vehicle has a computer system that lets you know
when to change the engine oil andfilter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage at which an oil change will be indicated can
vary considerably. For the oil life system to work
properly, you must reset the system every time the oil is
changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A CHANGE ENGINE OIL message will
come on. Change your oil as soon as possible within
the next two times you stop for fuel. It is possible that, if
you are driving under the best conditions, the oil life
system may not indicate that an oil change is necessary
for over a year. However, your engine oil andfilter
must be changed at least once a year and at this time
the system must be reset. Your dealer has GM-trained
service people who will perform this work using
genuine GM parts and reset the system.
It is also important to check your oil regularly and keep
it at the proper level.

Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts
as needed. Replace any components that have high
effort or excessive wear. Do not lubricate accelerator
and cruise control cables.
All-Wheel Drive Inspection
Inspect the transfer case (power transfer unit) and
carrier assembly-differential (rear drive module) every
12 months or at engine oil change intervals, check rear
differential and transfer case and add lubricant when
necessary. A uid loss could indicate a problem; check
and have it repaired, if needed. Check vent hoses at
transfer case and differential for kinks and proper
installation.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
cha ng, etc. Inspect disc brake pads for wear and rotors
for surface condition. For vehicles with rear drum
brakes, also inspect drum brake linings for wear and
cracks. Inspect other brake parts, including drums,
wheel cylinders, calipers, parking brake, etc. Check
parking brake adjustment. You may need to have your
brakes inspected more often if your driving habits or
conditions result in frequent braking.
