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.

* If your vehicle has the GM Oil Life System

t

, the

system will show you when to change the engine oil and
filter 

--

 usually between 3,000 miles (5 000 km) and

7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come on
before 3,000 miles (5 000 km). Never drive your vehicle
more than 7,500 miles (12 500 km) or 12 months without
an oil and filter change.

The system won’t detect dust in the oil. So if you drive in
a dusty area, be sure to change your oil and filter every
3,000 miles (5 000 km) or sooner if the CHANGE OIL
SOON message appears. Remember to reset the 
Oil Life System whenever the oil is changed. 
For more information, see “Oil Life System” in 
the Index.

+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under
“Periodic Maintenance Inspections” in Part C of 
this schedule.
