If this light comes on, it means that there is a problem with the VSC system that needs to be addressed immediately for safety reasons.

TRAC Off Light

The TRAC OFF (traction control off) light indicates that the traction control system has been turned off or disabled on your vehicle. The traction control system helps keep your car stable by detecting wheel spin and applying brake pressure at each wheel if needed in order to keep you from slipping or sliding while driving on slippery roads or during cornering maneuvers. If this light comes on, it means that there may be a problem with the traction control system and it should be addressed promptly in order to ensure maximum safety while driving.
