How to turn off trac off light

If the TRAC light is ON, check the switch behind the shifter, as it may have been switched on/off accidentally. If the light shows no change when using the switch, then I'd recommend visiting one of our RepairPal Certified shops in your area for diagnosis. The traction control system is part of the ABS/Electronic Brake Control Module (EBCM) and could indicate an underlying issue that may pose a safety risk depending on the nature of the issue.
