Reducing Speed While Using Cruise Control There are two ways to reduce the vehicle's speed while using cruise control: Using Cruise Control on Hills How well the cruise control will work on hills depends upon the speed and load of the vehicle, and the steepness of the hills. When going up steep hills, the accelerator pedal may have to be pressed to maintain the vehicle's speed. When going downhill, the vehicle's brakes may have to be used, or a lower gear may have to be used to keep the vehicle's speed down. Of course, applying the brake takes the vehicle out of cruise control. Many drivers find this to be too much trouble and do not use cruise control on steep hills. • Push in the SET button until the vehicle slows down to the desired, then release it. • To slow the vehicle down in very small amounts, push the SET button briefly. Each time this is down, the vehicle will go about 1 mph (1.6 km/h) slower. Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase the vehicle's speed. When you take your foot off the pedal, the vehicle will slow down to the cruise control speed that was set earlier. Ending Cruise Control There are two ways to turn off the cruise control: • Step lightly on the brake pedal. • Move the cruise switch to OFF. Ending Speed Memory When the cruise control or the ignition is turned off, or the vehicle is shifted into PARK (P) or NEUTRAL (N), the cruise control set speed memory is erased. 3-12
