Traction Control System (TCS) Warning Light

For vehicles with a Traction Control System (TCS) and StabiliTrak® warning light, this light comes on briefly when the engine is started.
If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off.
When the system is active, the light flashes while the system is limiting wheel spin or assisting with controlling the vehicle.
If it stays on or comes on while driving a SERVICE TRACTION CONTROL message appears in the Driver Information Center (DIC). This indicates that there could be a problem with the traction control system and the vehicle may need service. When this warning light is on and the SERVICE TRACTION CONTROL message appears on the DIC, the system does not limit wheel spin.
If the traction control system is manually turned off, this light comes on and the TRACTION CONTROL OFF message appears on the DIC.
See Traction Control System (TCS) and DIC Warnings and Messages for more information.
