The traction control system warning light comes on briefly while starting the engine.

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

This light comes on when your traction control system is limiting wheel spin. You may feel or hear the system working, but this is normal.

If the traction control system warning light comes on and stays on for an extended period of time when the system is turned on, the vehicle needs service. See Traction Control System (TCS) for more information.
