Reducing Speed While Using Cruise Control There are two ways to reduce the vehicle's speed while using cruise control: • Push the cruise control lever downward toward the minus (set/coast/decelerate) position until a lower speed is reached, then release it. • To slow down in very small amounts, push the cruise control lever downward toward the minus (set/coast/decelerate) position briefly. Each time this is done, the vehicle will slow down approximately one mph (1.6 km/h). When going downhill, the brakes might have to be applied, or the transaxle might have to be shifted to a lower gear to keep the vehicle's speed down. Doing either of these things will take the vehicle out of cruise. It may be better not to use the cruise control if the brakes constantly have to be applied, or the vehicle continuously needs to be shifted to a lower gear. Cancelling Cruise Control To cancel a cruise control session, pull the cruise control lever forward, or step lightly on the brake pedal. Doing either of these things will only end the current cruise control session, but the set speed will be retained in memory. Push the button at the end of the cruise control lever to turn the system off. 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 set earlier. Erasing Speed Memory When the cruise control or the ignition is turned off, the cruise control set speed memory is erased. Using Cruise Control on Hills How well the cruise control will work on hills depends upon the vehicle's speed, its load, and the steepness of the hills. When going up steep hills, the accelerator pedal might have to be used in order to maintain the vehicle's speed. 180
