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 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 Information Center (DIC) on page 4‑47. The StabiliTrak light will flash on the instrument panel cluster when the system is both on and activated. The traction control disable button is located on the instrument panel below the climate controls. The traction control part of StabiliTrak can be turned off by pressing and releasing the StabiliTrak button if both systems (traction control and StabiliTrak) were previously on. To disable both traction control and StabiliTrak, press and hold the button for five seconds. Traction control and StabiliTrak can be turned on by pressing and releasing the StabiliTrak button if not automatically shut off for any other reason. When the TCS or StabiliTrak system is turned off, the StabiliTrak light and the appropriate TCS off or StabiliTrak off 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. The system may be heard or felt while it is working; this is normal. 5-7
