Cruise Control { 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. 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). When the brakes are applied, cruise control is turned off. If the vehicle has StabiliTrak®, and the system begins to limit wheel spin, cruise control will automatically disengage. See StabiliTrak® System on page 5‑6. When road conditions allow the cruise control to be safely used again, it can be turned back on. 4-8 The cruise control buttons are located on left side of the steering wheel. I (On/Off): Turns the system on or off.
