Chevrolet 2007 Automobile User Manual


 
StabiliTrak
®
System
Your vehicle may be equipped with StabiliTrak
®
which combines anti-lock brake, traction and
stability control systems and helps the driver
maintain directional control of the vehicle in most
driving conditions.
When you first start your vehicle and begin to drive
away, the system performs several diagnostic
checks to insure there are no problems. You may
hear or feel the system working. This is normal and
does not mean there is a problem with your vehicle.
If the system fails to turn on or activate, the
SERVICE STABILITY SYSTEM message will be
displayed on the Driver Information Center (DIC). If
the vehicle has gone through heavy acceleration or
braking or multiple turns during the first two miles of
driving after starting your vehicle, the STABILITY
CONTROL OFF message may appear on the DIC.
If this is the case, your vehicle does not need
servicing. You will need to turn the vehicle off and
then restart it to initialize StabiliTrak
®
. If either
message appears on the DIC, and your vehicle has
not gone through hard acceleration, braking or
multiple turns in the first two miles of driving, your
vehicle should be taken in for service.
The STABILITY CONTROL ACTIVE message will
appear on the DIC only when the system is
both on and activated. It means that an advanced
computer-controlled system has come on to
help your vehicle continue to go in the direction in
which you are steering. StabiliTrak
®
activates
when the computer senses that your vehicle is just
starting to spin, as it might if you hit a patch of
ice or other slippery spot on the road. When
the system activates, you may hear a noise or feel
a vibration in the brake pedal. This is normal.
When the STABILITY CONTROL ACTIVE
message is on, you should continue to steer in the
direction you want to go. The system is designed
to help you in bad weather or other difficult driving
situations by making the most of whatever road
conditions will permit. For more information on the
stability messages, see Driver Information
Center (DIC) on page 249.
If the StabiliTrak
®
system turns off, the traction
control system warning light will illuminate, and the
STABILITY CONTROL OFF message will
appear on the DIC to warn the driver that
StabiliTrak
®
is no longer available to assist you
with directional control of the vehicle. Adjust your
driving accordingly.
