Setting C r P e Cont-l Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake. This, of course, shuts off cruise control. But you don't need to reset it. I if you leave your cruise control on when you're not using cruise, you might hit a button and go into cruise when you don't want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control. Once you're going about 25 mph (40 km/h) or more, you can move the cruise control switch briefly from ON to R/A (Resume/Accelerate). You'll go right back up to your chosen speed and stay there. If you hold the switch at R/A, the vehicle will keep going faster until you release the switch or apply the brake. You could be startled and even lose control. So unless you want to go faster, don't hold the switch at R/A. 1. Move the cruise control switch to ON. 2. Get up to the speed you want. 3. Press in the SET button located at the end of the lever and release it. 4. Take your foot off the accelerator pedal. 3-10
