re®lling your fuel tank. Once the range drops below
40 miles (64 km) remaining, the display will show LOW.
3-58

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. See
Oil Life Indicator on
page 3-79. SeeEngine Oil on page 5-13.
CHANGE TRANS FLUID ± 47:This message will
appear when it is time to change the transaxle ¯uid. See
Part A: Scheduled Maintenance Services on page 6-4for the proper ¯uid and change intervals.
CHECK BRAKE FLUID ± 37:This message will
display if the ignition is in ON to inform the driver that
the brake ¯uid level is low. Have the brake system
serviced by a technician as soon as possible. See
Brake
System Warning and Parking Brake Indicator Light on
page 3-47
.
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. See
Engine Coolant on page 5-24.
CHECK FUEL GAGE ± 50:(Analog Cluster) 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's 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. See
Engine Oil on page 5-13.
CHECK TIRE PRESSURE ± 144:This message is
displayed when the Tire Pressure Monitor (TPM) system
detects a low or high tire pressure condition in one or
more of the road tires. By pressing the INFO button up or
down, the DIC display will show which tire or tires do not
have the correct in¯ation pressure. A ªLOW TIREº
condition exists when the tire's air pressure is under
25 psi (172 kPa) and a ªHIGH TIREº condition exists
when the tire's air pressure is above 38 psi (262 kPa).
The system will display the air pressure, the tire location
(LF, RF, RR or LR) and if the air pressure is low or high.
The tire pressure information is available in English or
metric measurements. For example, a driver's side front
tire that is low may be shown as: 22 PSI LF TIRE LOW.

Trip Computer
Oil Life Indicator
This feature lets you know when to change the engine
oil. It's 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, see
Scheduled
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 doesn't check
how much oil you have, so you'll still have to check for
that. To see how, see
Engine Oil on page 5-13.
When the oil is changed, you'll need to reset the system.
See
Engine Oil on page 5-13. Always keep a written
record of the mileage and date when you changed
your oil.
3-79

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle ¯uid to use. SeePart D:
Recommended Fluids and Lubricants on page 6-15.
If the ¯uid level is low, add only enough of the proper
¯uid to bring the level into the cross-hatched area on the
dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough ¯uid at the
dipstick hole to bring it to the proper level.
It doesn't take much ¯uid, generally less than
one pint (0.5 L). Don't over®ll.
Notice:We recommend you use only ¯uid labeled
DEXRONž±III, because ¯uid with that label is
made especially for your automatic transaxle.
Damage caused by ¯uid other than DEXRON
ž±III is
not covered by your new vehicle warranty.
3. After adding ¯uid, recheck the ¯uid level as
described under
How to Check.
4. When the correct ¯uid level is obtained, push the
dipstick back in all the way and turn the handle
clockwise.
How to Reset the Transaxle Fluid
Indicator
After the transaxle ¯uid has been changed, the transaxle
¯uid change indicator must be reset. To reset the
indicator, do the following:
1. Press the INFO button on the Driver Information
Center (DIC) until TRANS FLUID LIFE is displayed.
2. Press and hold the RESET button until 100%
is displayed. This resets the transaxle ¯uid change
indicator.
The percentage of transaxle ¯uid life remaining may be
checked at any time by pressing the INFO on the
DIC until the TRANS FLUID LIFE message appears.
5-23

Once a low or high tire pressure condition is detected,
the TPM system will display the CHECK TIRE
MESSAGE each time the engine is started, until the
tire(s) are set to the correct in¯ation pressure.
The Tire-Loading Information Label, which is located on
the rear edge of the driver's door, shows the correct
in¯ation pressure for the tires on your vehicle.
The TPM system also allows the driver to check the air
pressure status of each road tire using the Driver
Information Center (DIC). Each tire's air pressure will be
listed individually, in the following order: LF (left front
or driver's side front tire), RF (right front or passenger's
side front tire), RR (right rear or passenger's side
rear tire) and LR (left rear or driver's side rear tire). See
In¯ation -- Tire Pressure on page 5-61for information
regarding correct tire in¯ation. Also, seeDriver
Information Center (DIC) on page 3-57for information on
the DIC controls and displays.If the DIC display doesn't show tire pressures or the
SERVICE TPM SYSTEM message appears, see
your dealer for service. The TPM system may not work
properly while the compact spare tire is installed.
Anytime you replace one or more tires or rotate your
tires, the TPM system will need to be reset. A special
tool is needed to reset the sensor identi®cation
codes. See your dealer for service.
Your vehicle was delivered from the factory with
aluminum valve stem caps. If you ever have to replace
the valve stem caps on your vehicle, you should
replace them with aluminum or plastic caps.
The TPM system can alert you about a low or high tire
pressure condition, but it doesn't replace normal tire
maintenance. See
Tires on page 5-60.
5-63

Tire Inspection and Rotation
Tires should be rotated every 7,500 miles (12 500 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment. Also
check for damaged tires or wheels. See
When It Is Time
for New Tires on page 5-65andWheel Replacement
on page 5-69for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The ®rst rotation
is the most important. See
Part A: Scheduled
Maintenance Services on page 6-4for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.Don't include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear in¯ation pressures as shown on the Tire-Loading
Information label.
Vehicles equipped with the Tire Pressure Monitor (TPM)
system will need to have the sensors reset after a tire
rotation is performed. A special tool is needed to
reset the sensor identi®cation codes. See your dealer
for service.
Make certain that all wheel nuts are properly tightened.
See ªWheel Nut Torqueº underCapacities and
Speci®cations on page 5-101.

Footnotes
²The 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,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-14.
Engine Oil Scheduled Maintenance
Change engine oil and ®lter as indicated by the GM
Oil Life System (or every 12 months, whichever
occurs ®rst). Reset the 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 ENGINE OIL message in the Driver
Information Center (DIC) 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 service 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. SeeEngine Oil on
page 5-13for information on resetting the system.
An Emission Control Service.
See the mileage intervals following for additional services
that may be performed with an engine oil change. After
the services are performed, record the date, odometer
reading and who performed the service on the
maintenance record pages in Part E of this schedule.
