Traction Control PRINCIPLES OF OPERATION The traction control system helps avoid drive wheel spin and loss of traction. 225 If your vehicle begins to slide, the system applies the brakes to individual wheels and, when needed, reduces engine power at the same time. If the wheels spin when accelerating on slippery or loose surfaces, the system reduces engine power in order to increase traction. USING TRACTION CONTROL (Dual rear wheel vehicles only) In certain situations (for example, stuck in snow or mud), turning the traction control off may be beneficial as this allows the wheels to spin with full engine power. Turn the traction control system off by pressing the stability control button located on the instrument panel. If the system cannot be turned off, see the MyKey chapter for more information. If traction control is on when your vehicle is put into four-wheel drive mode (if equipped), the traction control system will be automatically disabled. Traction control operation will resume when your vehicle is placed back into two-wheel drive mode.
