Specifications

* If your vehicle has the GM Oil Life System JM$ a
computer system lets you know when to change the
engine oil and filter. This is based on engine revolutions
and engine temperature, and not on mileage. Eased
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 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 ar: ~i/ chaqe 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;OOO miles (5 000 km] since yoru
last oil change. Remember to reset the oil life system
whenever the oil is changed. See Engine Oil on
page
5-13 for information on resetting the system.
@ Whenever the tires are rotated, the Check Tire
Pressure System (if equipped) must be reset.
+ A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-22.
