Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon the vehicle speed, load, and the steepness of the
hills. While going up steep hills, you might have to
step on the accelerator pedal to maintain the vehicle's
speed. While going downhill, you might have to brake or
shift to a lower gear to keep the vehicle's speed down.
When the brakes are applied the cruise control turns off.
