CHANGE ENGINE OIL – 82:This means that the life
of the engine oil has expired and it should be changed
within 200 miles. After an oil change, the Oil Life
Indicator must be reset. SeeOil Life Indicator on
page 3-74. SeeEngine Oil on page 5-13.
CHANGE TRANS FLUID – 47:This message will
appear when it is time to change the transaxle fluid. See
Scheduled Maintenance on page 6-4for the proper
fluid and change intervals.
CHECK BRAKE FLUID – 37:This message will
display if the ignition is in ON to inform the driver that
the brake fluid level is low. Have the brake system
serviced by a technician as soon as possible. SeeBrake
System Warning and Parking Brake Indicator Light on
page 3-43.
CHECK COOLANT LEVEL – 2:This message will
appear when there is a low level of engine coolant. Have
the cooling system serviced by a technician as soon
as possible. SeeEngine Coolant on page 5-23.
CHECK FUEL GAGE – 50:This message will appear
when the fuel supply is less than 5 gallons (18.9 L)
and the display is turned off. A single chime will also
sound when this message is displayed.CHECK GAS CAP – 61:This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it is on properly.
CHECK OIL LEVEL – 36:For correct operation of the
low oil sensing system, your vehicle should be on a
level surface. A false CHECK OIL LEVEL message may
appear if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time,
and the oil level is never checked while the engine is
running. If the CHECK OIL LEVEL message appears,
and your vehicle has been parked on level ground
with the engine off for at least 30 minutes, the oil level
should be checked by observing the oil dipstick. Prior to
checking the oil level, be sure the engine has been
off for a few minutes and your vehicle is on a level
surface. Then check the dipstick and add oil if
necessary. SeeEngine Oil on page 5-13.

Driver’s Name Set/Recall
If your vehicle has the optional memory package, you
will have this feature. This feature allows individual
driver’s names to be displayed in the DIC when
the ignition is turned to ON. This feature only works
when the remote keyless entry transmitter is used
to unlock the vehicle or when buttons 1 or 2 on the
driver’s door are pressed. See your dealer for assistance
in programming this feature.
Exiting Feature Programming
To exit FEATURE PROGRAMMING, press the INFO
RESET or INFO button.
Trip Computer
Oil Life Indicator
This feature lets you know when to change the engine
oil. It is based on the engine oil temperatures and
your driving patterns.
To see the display, press the INFO button several times
until ENGINE OIL LIFE appears. If you see 99% ENGINE
OIL LIFE, 99 percent of your current oil life remains.
The DIC may display a CHANGE ENGINE OIL message.
For more information, seeScheduled Maintenance on
page 6-4. If you see CHANGE ENGINE OIL, it means the
oil life is gone and you should change the oil right away.
The system does not check how much oil you have, so
you will still have to check for that. To see how, see
Engine Oil on page 5-13.
When the oil is changed, you will need to reset the
system. SeeEngine Oil on page 5-13. Always keep a
written record of the mileage and date when you
changed your oil.

When You Are Ready to Leave After
Parking on a Hill:
1. Apply your regular brakes and hold the pedal down
while you:
•start your engine,
•shift into a gear, and
•make sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you are
pulling a trailer. See the Maintenance Schedule for
more on this. Things that are especially important in
trailer operation are automatic transaxle fluid (do
not overfill), engine oil, drive belt, cooling system and
brake system. Each of these is covered in this manual,
and the Index will help you find them quickly. If you
are trailering, it is a good idea to review this information
before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-26.

Service
Your dealer knows your vehicle best and wants you to
be happy with it. We hope you will go to your dealer
for all your service needs. You will get genuine GM parts
and GM-trained and supported service people.
We hope you will want to keep your GM vehicle all GM.
Genuine GM parts have one of these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you
will want to use the proper service manual. It tells
you much more about how to service your vehicle than
this manual can. To order the proper service manual,
seeService Publications Ordering Information on
page 7-12.
Your vehicle has an air bag system. Before attempting
to do your own service work, seeServicing Your Air
Bag-Equipped Vehicle on page 1-50.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. SeeMaintenance Record on page 6-14.
{CAUTION:
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.
•Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
CAUTION: (Continued)
5-3

CAUTION: (Continued)
•
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused. If you
use the wrong fasteners, parts can later
break or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind
noise and affect windshield washer performance. Check
with your dealer before adding equipment to the
outside of your vehicle.
Fuel
Use of the recommended fuel is an important part of the
proper maintenance of your vehicle.
Gasoline Octane
Use regular unleaded gasoline with a posted octane of
87 or higher. However, for best performance and for
trailer towing, you may wish to use middle grade
or premium unleaded gasoline. If the octane is less than
87, you may get a heavy knocking noise when you
drive. If this occurs, use a gasoline rated at 87 octane
or higher as soon as possible. Otherwise, you might
damage your engine.

Maintenance Replacement Parts on page 6-13for
the proper type.
