If the traction control warning light comes on and stays on, there may be a problem with the traction control system.

The traction control warning light will come on briefly when you turn the ignition to ON. If it does not come on then, have it fixed so it will be ready to warn you if there is a problem. See Traction Control System (TCS) for more information.

Your vehicle may have a Traction Control System (TCS) warning light.

If this warning light comes on and stays on, there may be a problem with the TCS and, if your vehicle has this feature, the StabiliTrak® system.

The TCS warning light will come on briefly when you turn the ignition to RUN. If it does not come on then, have it fixed so it will be ready to warn you if there is a problem.

If the TCS warning light stays on or comes on while you are driving, pull off the road as soon as possible and stop carefully. Try resetting the system by turning the ignition off then back on. If the light still stays on or comes back on again while you are driving, your vehicle needs service. Have the traction control system and, if your vehicle has this feature, the StabiliTrak® system inspected as soon as possible. See Traction Control System (TCS) and StabiliTrak® System for more information.
