This light should come on briefly as the engine is started.

If the light does not come on then, have it fixed so it is ready to warn if there is a problem.

The light also comes on while the Stabilitrak® system warms up and the STABILITRAK WARMING message displays in the Driver Information Center (DIC).

If it stays on, or comes on and the DIC shows a SERVICE TRACTION SYS message while driving, there is a problem with the Traction Control System (TCS) and the vehicle needs service. When this light is on, the system will not limit wheel spin. Adjust driving accordingly. If the driver turns off TCS by pressing the button on the console, the TCS light will come on and the TRACTION SYSTEM OFF message shows on the DIC.

If the light stays on or comes on while driving, a chime sounds and a SERVICE STABILITRAK message appears on the DIC, there is a problem with the Stabilitrak® and the vehicle needs service.

This message can be acknowledged by pressing the RESET button. When the SERVICE STABILITRAK message is displayed, the Stabilitrak® system will not assist with controlling the vehicle. The system needs service as soon as possible. Adjust driving accordingly.

When the system is working, the STABILITRAK ACTIVE message displays in the DIC.

If the Stabilitrak® system is turned off, by pressing the front part of the button on the console for five seconds, the TCS light will come on, a chime will sound and the TRAC/STABILITRAK OFF message displays in the DIC. The TCS will also be turned off. See DIC Warnings and Messages for more information.

If the Stabilitrak® system and TCS are turned off, pressing the console button momentarily will turn both systems on. The DIC displays the TRAC/STABILITRAK ON message, the instrument cluster light is off and a chime sounds. See DIC Warnings and Messages for more information.
