The trac off light is on
Your traction control is off. Either the switch was pushed by accident or there's a problem with the traction control system or antilock brake system. Is you ABS light on? If so, have the antilock brake system repaired. The ABS and traction control systems are tied together. If a fault occurs in the ABS system the traction control is automatically disabled. HTH. -Jim
