Using Cruise Control on Hills

How well the cruise control will work on hills depends upon your speed load, and the incline of the hills. When going up steep hills, you may have to step on the accelerator pedal in order to maintain your speed. When going downhill, you may have to shift to a lower gear or brake in order to keep your speed down. Applying the brake will take you out of cruise control. Many drivers find this to be too much trouble and choose not to use the cruise control on steep hills.
