StabiliTrak System
Your vehicle is equipped with StabiliTrak
combines antilock 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. The system
should initialize before the vehicle reaches 20 mph
(32 km/h). In some cases, it may take approximately
two miles of driving before the system initializes.
If the system fails to turn on or activate, the STABILITY
SYS DISABLED or SERVICE STABILITY message
will be displayed. 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 SYS DISABLED message may appear.
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
the Driver Information Center (DIC), and your vehicle
hasn't 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 SYS ACTIVE message will appear on
the Driver Information Center (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're
®
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 SYS 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 3-46.
