Footnotes
t
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
good time to check your brakes is during tire
rotation. See Brake System Inspection on page
6-16.
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 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 ENGINE
OIL
light 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 5-15 for information on resetting the system.
After the services are performed, record the date,
odometer reading and who performed the service on the
maintenance record pages in Part E of this schedule.
