Resuming aSet Speed Suppose you set your cruise controlat 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'regoing about 25 mph (40 km/h) or more, you can move the cruise control switch from ON to R/A for about 1 1/2 seconds. Increasing Speed While Using Cruise Control There are two ways to go to a higher speed: Use the accelerator pedal to get to the higher speed. Press the button at the end of the lever, then release the button and the accelerator pedal. You'll now cruise at the higher speed. 0 1 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 for less than 3/4 of a second.Each time you do this, your vehicle will go about 1 mph (1.6 km/h) faster.) Reducing Speed While Using Cruise Control You'll go right back up to your chosen speed and stay there. Remember, if you hold the switch at R/A longer than 1 1/2 seconds, the vehicle will keep going faster until you release the switch or apply the brake. So unless you want to go faster, don't hold the switch at R/A. There are two ways to reduce your speed while using cruise control: Press the 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 button for less than 1/2 of a second. Each time you do this, you'll go 1 mph (1.6 k d h ) slower. 2-36
