When to Change Engine Oil
(GM Oil Life System)
Your vehicle has a computer system that lets you know
when to change the engine oil and lter. 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 ENG 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 lter must be
changed at least once a year and at this time the system
must be reset. Your dealer has GM-trained people
who will perform this work using genuine GM parts and
reset the system. 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.
How to Reset the CHANGE ENG OIL Light
The GM Oil Life System calculates when to change your
engine oil and lter based on vehicle use. Anytime your
oil is changed, reset the system so it can calculate when
the next oil change is required. If a situation occurs where
you change your oil prior to a CHANGE ENG OIL light
being turned on, reset the system.
To reset the CHANGE ENG OIL light, do the following:
1. Turn the ignition key to RUN with the engine off.
2. Fully press and release the accelerator pedal slowly
three times within ve seconds.
3. Turn the key to LOCK.
If the CHANGE ENG OIL light comes back on when you
start your vehicle, the engine oil life system has not
reset. Repeat the procedure.
For vehicles with the Driver Information Center, see
Driver Information Center (DIC) on page 3-45to reset
the system.

You may have an air inator kit that is located in the
glove compartment. The kit includes a 22 ft (6.7 m)
hose with three nozzle adapters.
To use the air inator attach the appropriate nozzle
adapter to the end of the hose if required. Then attach
that end of the hose to the object you wish to inate.
Attach the other end of the hose to the outlet.
Press and release the switch to turn the air inator on.
The indicator light will remain on when the inator is
running.
The system has an internal clock to prevent overheating.
The system will allow about ve minutes of running
time, then the compressor will stop. The indicator light
will then begin to ash. When the indicator is off,
the inator can be started again by pressing the switch.
If the compressor is still hot, it may only run for a
short time before shutting off again.
Press and release the switch to turn the inator off.
Place the inator kit tools in the pouch and store
it properly. Remove the inator hose from the outlet
during loading and unloading. Load leveling will
not function with the inator hose attached to the inator
outlet. See “Electronically Controlled Air Suspension
System” in the Index.To reinstall the cover, line up the tabs at the back of the
cover, put it in place and latch the tabs.
A continuous ashing indicator light may also indicate a
malfunction in the air suspension system. See
“Electronically Controlled Air Suspension System” in the
Index.
{CAUTION:
Inating something too much can make it
explode, and you or others could be injured.
Be sure to read the inator instructions, and
inate any object only to its recommended
pressure.
