Antilock Brake System (ABS)
Warning Light
The Antilock Brake
System (ABS) light comes
on briefly when the engine
is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 4-27.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 4-44for all

Driver Information Center (DIC)Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located
below the speedometer in the instrument panel cluster.
The DIC buttons are located on the instrument panel,
to the right of the instrument panel cluster.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was
last displayed before the engine was turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system problem
is detected. The bottom line of the DIC shows the shift
lever position indicator. SeeAutomatic Transmission
Operation on page 3-24for more information.
If your vehicle has these features, the DIC also displays
the compass direction and the outside air temperature
when viewing the trip and fuel information. The compass
direction appears on the top right corner of the DIC
display. The outside air temperature automatically
appears in the bottom right corner of the DIC display.
If there is a problem with the system that controls the
temperature display, the numbers will be replaced with
dashes. If this occurs, have the vehicle serviced by your
dealer/retailer.
The DIC also allows some features to be customized.
SeeDIC Vehicle Customization on page 4-51for
more information.

Vehicle Information Menu Items
T
(Vehicle Information):Press this button to scroll
through the following menu items:
Oil LifePress the vehicle information button until OIL LIFE
REMAINING displays. This display shows an estimate of
the oil’s remaining useful life. If you see 99% OIL LIFE
REMAINING on the display, that means 99% of the
current oil life remains. The engine oil life system will alert
you to change the oil on a schedule consistent with your
driving conditions.
When the remaining oil life is low, the CHANGE ENGINE
OIL SOON message will appear on the display. See
“CHANGE ENGINE OIL SOON” underDIC Warnings
and Messages on page 4-44. You should change the
oil as soon as possible. SeeEngine Oil on page 6-15.
In addition to the engine oil life system monitoring the
oil life, additional maintenance is recommended in the
Maintenance Schedule in this manual. SeeScheduled
Maintenance on page 7-3for more information.
Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be careful not
to reset the OIL LIFE accidentally at any time other than
when the oil has just been changed. It cannot be reset
accurately until the next oil change. To reset the engine
oil life system, seeEngine Oil Life System on page 6-18.
UnitsPress the vehicle information button until UNITS
displays. This display allows you to select between
English or Metric units of measurement. Once in this
display, press the set/reset button to select between
ENGLISH or METRIC units.Tire PressureOn vehicles with the Tire Pressure Monitor System
(TPMS), the pressure for each tire can be viewed in the
DIC. The tire pressure will be shown in either pounds per
square inch (psi) or kilopascals (kPa). Press the vehicle
information button until the DIC displays FRONT TIRES
PSI (kPa) LEFT ## RIGHT ##. Press the vehicle
information button again until the DIC displays REAR
TIRES PSI (kPa) LEFT ## RIGHT ##.
If a low tire pressure condition is detected by the system
while driving, a message advising you to add air to a
specific tire will appear in the display. SeeInflation - Tire
Pressure on page 6-59andDIC Warnings and Messages
on page 4-44for more information.
If the tire pressure display shows dashes instead of a
value, there may be a problem with your vehicle. If this
consistently occurs, see your dealer/retailer for service.

Engine Oil Additives / Engine Oil
FlushesDo not add anything to the oil. The recommended oils
with the starburst symbol that meet GM Standard
GM6094M are all that is needed for good performance
and engine protection.
Engine oil system flushes are not recommended and
could cause engine damage not covered by the vehicle
warranty.Engine Oil Life SystemWhen to Change Engine OilThis vehicle has a computer system that indicates when
to change the engine oil and filter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change is indicated can vary considerably.
For the oil life system to work properly, the system
must be reset every time the oil is changed.When the system has calculated that oil life has been
diminished, it indicates that an oil change is necessary.
A CHANGE ENGINE OIL SOON message comes on.
SeeDIC Warnings and Messages on page 4-44.
Change the oil as soon as possible within the next
600 miles (1 000 km). It is possible that, if driving under
the best conditions, the oil life system might not
indicate that an oil change is necessary for over a year.
However, the engine oil and filter must be changed
at least once a year and at this time the system must
be reset. Your dealer/retailer has trained service people
who will perform this work using genuine parts and
reset the system. It is also important to check the oil
regularly and keep it at the proper level.
If the system is ever reset accidentally, the oil must be
changed at 3,000 miles (5 000 km) since the last oil
change. Remember to reset the oil life system whenever
the oil is changed.
