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 to maintain your speed. When going downhill, you may have to brake or shift to a lower gear to maintain your speed. However, applying the brake will turn off the cruise control. Many drivers find this to be too much trouble and choose not to use cruise control on steep hills.
