I believe you are referring to the Traction Control light. The following information might help.
If your vehicle is equipped with the Enhanced Traction System (ETS), this warning light should come on briefly as you start the engine. If the warning light does not come on, then have it fixed so it will be ready to warn you if there is a problem.
If the warning light stays on, or comes on when you are driving, there may be a problem with your Enhanced Traction System and your vehicle may need service. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly.
The Enhanced Traction System warning light may come on for the following reasons:
If the Enhanced Traction System warning light comes on and stays on for an extended period of time when the transaxle shift lever is in any position other than FIRST (1), your vehicle needs service.
If you have more questions, just let me know.
Take Care, Greg A.
