Increasing Speed While Using Cruise Control There are two ways to go to a higher speed: 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. • Use the accelerator pedal to get to the higher speed. Press the set button at the end of the lever, then release the button and the accelerator pedal. You'll now cruise at the higher speed. 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 want 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. • Move the cruise switch from on to resume/accelerate. Hold it there until you get up to the speed you want, and then release the switch. To increase your speed in very small amounts, move the switch to resume/accelerate briefly. Each time you do this, your vehicle will go about 1 mph (1.6 km/h) faster. Reducing Speed While Using Cruise Control • Press and hold the set button at the end of the lever until you reach the lower speed you want, then release it. • To slow down in very small amounts, press the set button briefly. Each time you do this, you'll go about 1 mph (1.6 km/h) slower. 3-13
