Driving and Operating Increasing Speed While Using Cruise Control There are two ways to go to a higher speed: . 9-59 Reducing Speed While Using Cruise Control . Using Cruise Control on Hills How well the cruise control works on hills depends upon the vehicle's speed, load, and the steepness of the hills. When going up steep hills, the accelerator pedal might have to be used to maintain the vehicle speed. When going downhill, you might have to brake or shift to a lower gear to keep the vehicle speed down. When the brake is applied the cruise control will turn off. Use the accelerator pedal to get to the higher speed. Press T at the end of the lever, then release the button and the accelerator pedal. The vehicle will now cruise at the higher speed. If the accelerator pedal is held longer than 60 seconds, cruise control will turn off. Move the cruise switch from R to S. Hold it there until the desired speed is reached, and then release the switch. To increase the vehicle speed in small amounts, move the switch briefly to resume/accelerate. Each time this is done, the vehicle goes about 1.6 km/h (1 mph) faster. Press and hold T until the desired lower speed is reached, then release it. To slow down in very small amounts, briefly press T. Each time this is done, the vehicle goes about 1.6 km/h (1 mph) slower. . Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase the vehicle speed. When you take your foot off the pedal, the vehicle slows down to the cruise control speed set earlier. .
