StabiliTrak
®
System
Your vehicle may be equipped with the StabiliTrak
®
system which 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 ensure
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 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 steering wheel clockwise from the nine
o’clock position to the three o’clock position. If this clears
the message(s), your vehicle does not need servicing.
If this does not clear the message(s), then turn the
vehicle off, wait 15 seconds, and then turn it back on
again to reset the system. If any of these messages still
appear on the Driver Information Center (DIC), your
vehicle should be taken in for service. For more
information on the DIC messages, see Driver
Information Center (DIC) on page 3-49.
The StabiliTrak
®
light will
flash on the instrument
panel cluster when
the system is both on and
activated.
You may also feel or hear the system working; this is
normal.
