Reducing Speed While Using Cruise Control There are two ways to reduce your speed while using cruise control: • Push the lever downward toward the minus (set/coast/decelerate) position until you reach the lower speed you want, then release it. When going downhill, you may have to brake or shift to a lower gear to keep your speed down. Applying the brake or shifting into a lower gear will take you out of cruise control. If you need to apply the brake or shift to a lower gear due to the grade of the downhill slope, you may not want to attempt to use your cruise control feature. 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 two things will only end the current cruise control session, but the set speed will be retained in memory. You must push the button at the end of the cruise control lever to turn the system off. • To slow down in very small amounts, push the lever downward toward the minus (set/coast/decelerate) position briefly. Each time you do this, the vehicle will slow down approximately 1 mph (1.6 km/h). Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase your speed. When you take your foot off the pedal, your vehicle will slow down to the cruise control speed you set earlier. Erasing Speed Memory When you turn off the cruise control or the ignition, your cruise control set speed memory is erased. Using Cruise Control on Hills How well your 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. 3-11
