Traction control forms part of the stability control system.
The system automatically turns on every time you switch the ignition on.
Switching off the stability control will turn off the system.
In certain situations (e.g. stuck in snow or mud), turning the system off may be beneficial as this allows the wheels to spin with full engine power.
Traction control is an enhanced feature of stability control system and automatically detects the wheel spin when you accelerate. If this situation occurs, the system applies your vehicle brakes at individual wheels and if necessary, reduces engine power.
Shifting to 4x4 Low deactivates engine traction control but brake traction control remains active.
