Using Cruise Control on Hills
How well the 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 speed. When going downhill, the vehicle may automatically shift to a lower gear to keep the vehicle's speed down.
The vehicle may then shift to a higher gear when braking assistance is no longer required.
When the brakes are applied manually the cruise control is disengaged.
