The Traction Control System (TCS)/StabiliTrak® system warning light comes on briefly as the engine is started.

If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator lights go off.

This light flashes while the Traction Control System (TCS) and/or the StabiliTrak system are working. It also flashes when the Antilock Brake System (ABS) is activated.

If the light comes on and stays on while driving there is a problem with the Traction Control System (TCS) or the StabiliTrak system. The TCS and/or StabiliTrak system automatically turns off and vehicle needs service.

When this light is on, the TCS system does not limit wheel spin and/or the StabiliTrak system does not assist with vehicle control.

When the Traction Control system and/or StabiliTrak system are turned off, the light comes on.

When the Traction Control System and/or StabiliTrak system are turned on, the light turns off.

See Traction Control System (TCS) and StabiliTrak® System for more information.
