Using Cruise Control on Hills How well your cruise control works on hills depends upon the vehicle speed, load, and the steepness of the hills. When going up steep hills, you might have to step on the accelerator pedal to maintain the vehicle's speed. When going downhill, you might have to brake or shift to a lower gear to keep the vehicle's speed down. Applying the brake or shifting into a lower gear ends cruise control. If you need to apply the brake or shift to a lower gear due to the grade of the downhill slope, you might not want to attempt to use the cruise control feature.

Adaptive Cruise Control (ACC) is an enhancement to traditional cruise control. It allows you to keep cruise control engaged in moderate traffic conditions without having to constantly reset your cruise control. ACC uses radar to detect a vehicle directly ahead in your path, within a distance of 100 m (330 ft), and operates at speeds above 40 km/h (25 mph). When it is engaged by the driver, the system can apply limited braking or acceleration of the vehicle automatically to maintain a selected follow distance to the vehicle ahead. Braking is limited to 2.45 m/sec2 (0.25 g's) of deceleration, which is comparable to moderate 4-15 Ending Cruise Control To turn off the cruise control, step lightly on the brake pedal, or press the cancel button on the steering wheel.
