Driving Cruise control* The vehicle maintains and stores the speed that you set at speeds greater than approx. 20 mph/ 30 km/h. You can use cruise control whenever the system is active while the engine is running. Do not use the cruise control under unfavorable conditions that do not permit a constant speed, e.g. when driving on winding roads or in heavy traffic or when negotiating poor road conditions such as snow, rain, ice, or a loose road surface. Otherwise, you could lose control of the vehicle and cause an accident.< Maintaining speed, storing, and accelerating Briefly press + button: The system maintains and stores the current vehicle speed. Each additional touch of the button increases the speed by approx. 1 mph/ 1 km/h. Press and hold + button: The vehicle accelerates without pressure on the accelerator pedal. When you release the button, the system maintains and stores the current speed. If the braking action of the engine is insufficient on a downhill stretch, then the set vehicle can exceed the set speed. Speed can drop on uphill grades if the engine output is insufficient.
