Resuming a Set Speed Suppose you set the cruise control at a desired speed and then you apply the brake. This, of course, shuts off the cruise control. But you don't need to reset it. Once you're going about 25 mph (40 km/h) or more again, you can move the cruise control switch from ON to R/A (Resume/Accelerate) briefly. You'll go right back up to your chosen speed and stay there. Reducing Speed While Using Cruise Control There are two ways to reduce your speed while using cruise control: e Push in the SET button until you reach the lower speed you want, then release it. 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. e Increasing Speed While Using Cruise Control There are two ways to go to a higher speed: e 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. Use the accelerator pedal to get to the higher speed. Push in the §ET button, then release the button and the accelerator pedal. You'll now cruise at the higher speed. Move the cruise switch from ON to R/A. 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 R/A briefly and then release it. Each time you do this, your vehicle will go about 1 mph (1.6 km/h) faster. e 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. The accelerate feature will only work after you set the cruise control speed by pushing the SET button. 3-9
