Long Trip/Highway Scheduled
Maintenance
The services shown in this schedule up to 100,000 miles
(166
000 km) should be repeated after 100,000 miles
(1 66 800 km) at the same intervals for the life of
this vehicle. The services shown at 150,000 miles
(240 000 km) should be repeated at the same interval
after 150,000 miles
(240 000 km) for the life of this
vehicle.
See
Part B: Owner Checks and Services on page 6-18
and Part C: Periodic Maintenance Inspections on
page 6-22.
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,
urqe that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
* If your vehicle has the GM Oil Life SystemTM, a
computer system lets you know when to change the
engine oil and filter. This is based on engine revolutions
aiid eiigifie telvpei-atdre, and ncf c:: ml?eage. 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 wil! 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
5-75 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
6-23.
