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

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), the
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), the vehicle should be taken in for service.
For more information on the DIC messages, see Driver

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.
