Cruise Control If your vehicle has cruise control, the controls are located on the end of the turn signal/multifunction lever. With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). If you apply your brakes, the cruise control will shut off. {CAUTION: Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use your 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 needless wheel spinning, and you could lose control. Do not use cruise control on slippery roads. R(On): Move the switch to this position to turn the cruise control system on. S(Resume/Accelerate): Move the switch to this position to resume a set speed or to accelerate. T(Set): Press this button, located at the end of the lever, to set a speed. 9(Off): This position turns the cruise control system off and cancels memory of a set speed. 3-11
