Oil Pressure Light
If your vehicle has low
engine oil pressure, this
light will stay on after
you start your engine, or
come on when you
are driving.
This indicates that your engine is not receiving
enough oil. The engine could be low on oil,
or could have some other oil problem. Have it
xed immediately by your dealer.
The oil light could also come on in three other
situations:
When the ignition is on but the engine is not
running, the light will come on as a test to
show you it is working. The light will go
out when you turn the ignition on. If it does
not come on with the ignition on, you
may have a problem with the fuse or bulb.
Have it xed right away.
If you are idling at a stop sign, the light may
blink on and then off.
If you make a hard stop, the light may come
on for a moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others
could be burned. Check your oil as soon
as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

Using the Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we do
not know exactly how you will drive it. You may
drive very short distances only a few times a week.
Or you may drive long distances all the time in
very hot, dusty weather. You may use your vehicle
in making deliveries. Or you may drive it to
work, to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You may
need more frequent checks and replacements. So
please read the following and note how you
drive. If you have any questions on how to keep
your vehicle in good condition, see your GM
Goodwrench
®dealer.This schedule is for vehicles that:
carry passengers and cargo within
recommended limits. You will nd these limits
on the Tire and Loading Information label.
SeeLoading Your Vehicle on page 404.
are driven on reasonable road surfaces within
legal driving limits.
use the recommended fuel. SeeGasoline
Octane on page 429.
The services inScheduled Maintenance on
page 539should be performed when indicated.
SeeAdditional Required Services on page 542and
Maintenance Footnotes on page 543for further
information.

Scheduled Maintenance
When the CHANGE OIL SOON message comes
on, it means that service is required for your
vehicle. Have your vehicle serviced as soon as
possible within the next 600 miles (1 000 km). It is
possible that, if you are driving under the best
conditions, the engine oil life system may
not indicate that vehicle service 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 GM
Goodwrench
®dealer has GM-trained service
technicians who will perform this work using
genuine GM parts and reset the system.If the engine oil life system is ever reset
accidentally, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
page 442for information on the Engine Oil Life
System and resetting the system.
When the CHANGE OIL SOON message appears,
certain services, checks, and inspections are
required. Required services are described in the
following for “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that your rst
service be MaintenanceI, your second service be
MaintenanceII, and that you alternate
MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.
