Reducing Speed While Using Cruise Control There are two ways to reduce your speed while using cruise control: Using Cruise Control on Hills How well the cruise control will work on hills depends upon your speed, load and the steepness 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 keep your speed down. Of course, applying the brake takes you out of cruise control. Many drivers find this to be too much trouble and don't use cruise control on steep hills. Ending Cruise Control There are two ways to turn off the cruise control: D Push in the SET button until you reach the lower speed you want, then release it. D To slow down in very small amounts, push the SET button briefly. Each time you do this, you'll go about 1 mph (1.6 km/h) slower. Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase your speed. When you take your foot off the pedal, the vehicle will slow down to the cruise control speed you set earlier. D Step lightly on the brake pedal, D or move the cruise switch to OFF. Erasing Cruise Speed Memory When you turn off the cruise control or the ignition, or shift into PARK (P) or NEUTRAL (N), the cruise control set speed memory is erased. 2-54
