Traction Control PRINCIPLE OF OPERATION The traction control system helps avoid drive wheel spin and loss of traction. 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. E162724 Turn the traction control system off by pressing the stability control button located on the instrument panel. If you cannot turn the system off, see the MyKey chapter for more information. Placing your vehicle into four-wheel drive mode automatically disables traction control. Traction control operation will resume when you place your vehicle back into two-wheel drive mode. USING TRACTION CONTROL (Dual rear wheel vehicles only) In certain situations (for example, stuck in snow or mud), it may be beneficial to turn the traction control system off. This allows the wheels to spin with full engine power.
