To Resume a Set Speed Suppose you set your 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 goingabout 25 mph (40 k d h ) or more, you can move the Cruise Control switch from ON to R/A (Resume/Accelerate) and hold it for about half a second. You'll go right back up to your chosen speed and staythere. Remember, if you hold the switch at R/A (Resume/Accelerate) longer than half a second, 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 (Resume/Accelerate). R/A 2-37
