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, a computer
system lets you know when to change the oil and
filter. 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.
An ENGINE OIL CHANGE SOON 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 and filter must be changed at
least once a year and at this time the system must be
reset. It is also important to check your oil regularly and
keep it at the proper level.

If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed. See Engine Oil
on
page 5-16 for information on resetting the system.

Whenever the tires are rotated, the Check Tire Pressure
System must be reset.

+ A good time to check your brakes is during tire
rotation. See Brake System Inspection
on page 6-24.
