If your vehicle has the Traction Assist System, this light should come on briefly when you turn the ignition to RUN.

If the light does not come on then, the system may require service. Have it fixed so it will be there to warn you if the system is turned off.

If the light stays on, or comes on when you are driving, there may be a problem with your Traction Assist System and your vehicle may need service. When this light is on, the system will not limit wheel spin. Adjust your driving accordingly.
