† 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 a Driver Information Center (DIC),
it also has the GM Oil Life System, a computer system
that 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. A CHANGE OIL SOON message on the
Driver Information Center (DIC) will come on. See DIC
Warnings and Messages on page 3-38. Change
your oil as soon as possible within the next two times
you stop for fuel. See Engine Oil on page 5-13. 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 Life System
on page 5-16 for information on resetting the system.
+ A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-20.
