Cruise Control With cruise control, a speed of about 40 km/h (25 mph) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about 40 km/h (25 mph). If the brakes are applied, the cruise control shuts off. If the vehicle is in cruise control when the Traction Control System (TCS) begins to limit wheel spin or the stability control system activates, the cruise control automatically disengages. See Traction Control System (TCS) on page 5‑9 and StabiliTrak® System on page 5‑6 or Enhanced StabiliTrak® on page 5‑7. When road conditions allow you to safely use it again, the cruise control can be turned back on. These controls are located on the end of the multifunction lever. { WARNING: Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use the cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. 9 (Off) : Turns the system off. R (On) : Turns the system on. + (Resume/Accelerate) : Use this position to make the vehicle resume a previously set speed or accelerate when cruise is already active. 4-12
