This light comes on briefly when the
ignition key is turned to ON/RUN.
If it does not come on then, have it
fixed so it is ready to warn if there is
a problem.

WARNING (Continued)
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push
or might go closer to the floor. It can
take longer to stop. If the light is
still on, have the vehicle towed for
service. See Towing the Vehicle
on
page 10‑101.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is started.
If it does not, have the vehicle
serviced by your dealer. 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.

Driving and Operating 9-71
The system should initialize before
the vehicle reaches 32 km/h
(20 mph). In some cases, it may
take approximately 3.2 km (2 miles)
of driving before the system
initializes.
If cruise control is being used when
StabiliTrak activates, the cruise
control automatically disengages.
The cruise control can be
re-engaged when road conditions
allow. SeeCruise Control
on
page 9‑73for more information.
If the system fails to turn on or
activate, the StabiliTrak light
along with one of the following
messages will be displayed on the
Driver Information Center (DIC):
TRACTION CONTROL OFF,
SERVICE TRACTION CONTROL,
STABILITRAK OFF, SERVICE
STABILITRAK. If these DIC
messages appear, make sure
the StabiliTrak system has not
been turned off using the StabiliTrak
on/off button. Then turn the vehicle
off, wait 15 seconds, and turn it
back on again to reset the system. If any of these messages still
appear on the DIC, the vehicle
should be taken in for service.
For more information on the DIC
messages, see
Ride Control System
Messages on page 5‑49.The StabiliTrak light will flash on the
instrument panel cluster when the
system is both on and activated.
The system may be heard or felt
while it is working; this is normal.
The traction control disable button
is located on the instrument panel
below the climate controls. The Traction Control System (TCS)
part of StabiliTrak can be turned
off by pressing and releasing the
StabiliTrak button. To disable both
TCS and StabiliTrak, press and
hold
5untilFilluminates and the
appropriate DIC message displays.
TCS and StabiliTrak can be turned
on by pressing and releasing the
StabiliTrak button if they are not
automatically shut off for any other
reason.
When TCS or StabiliTrak is
turned off, the StabiliTrak light
and the appropriate message
will be displayed on the DIC to
warn the driver. The vehicle will still
have brake-traction control when
traction control is off, but will not
be able to use the engine speed
management system. See “Traction
Control Operation” next for more
information.
When the traction control system
has been turned off, system noises
may still be heard as a result of the
brake-traction control coming on.

Vehicle Care 10-9
Cold Temperature Operation
If in an area of extreme cold,
where the temperature falls below
−29°C (−20°F), use either an
SAE 5W-30 synthetic oil or an
SAE 0W-30 engine oil. Both provide
easier cold starting for the engine
at extremely low temperatures.
Always use an oil that meets the
required specification, GM6094M.
See“What Kind of Engine Oil to
Use” for more information.
Engine Oil Additives/Engine
Oil Flushes
Do 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 System
When to Change Engine Oil
This 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.
On some vehicles, when the system
has calculated that oil life has been
diminished, a CHANGE ENGINE
OIL SOON message comes on
to indicate that an oil change
is necessary. See Engine Oil
Messages
on page 5‑47. Change
the oil as soon as possible within
the next 1 000 km (600 miles). 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.
For vehicles without the CHANGE
ENGINE OIL SOON message, an
oil change is needed when the OIL
LIFE REMAINING percentage is
near 0%. Your dealer 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 5 000 km (3,000 miles)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
