WARNING   WARNING:  The stability and traction control light illuminates steadily if the system detects a failure. Make sure you did not manually disable the traction control system using the information display controls or the switch. If the stability control and traction control light is still illuminating steadily, have the system serviced by an authorized dealer immediately. Operating your vehicle with the traction control disabled could lead to an increased risk of loss of vehicle control, vehicle rollover, personal injury and death.

The traction control system turns on each time you switch the power on.
If your vehicle is stuck in mud or snow, switching traction control off may be beneficial as this allows the wheels to spin.
Note:   When you switch traction control off, stability control remains fully active.
Your vehicle could have MyKey restrictions regarding this feature.   See   What Is MyKey
