Adaptive Cruise Control (ACC) Overview Adaptive cruise control (ACC) allows you to maintain a set speed and keep the vehicle ahead of you and your vehicle at a safe distance without having to use the accelerator pedal or the brake pedal. When the vehicle ahead of you slows down or speeds up, ACC senses the change in distance and compensates by adjusting your vehicle speed accordingly. The distance between vehicles is based on your speed: the faster you go, the longer the distance will be; the slower you go, the shorter it will be. If the vehicle ahead of you slows down suddenly or another vehicle cuts in front of your vehicle, ACC alerts you by sounding a beeper and displaying a message on the multiinformation display. The ACC radar sensor in the front grille can detect and monitor the distance of a vehicle up to 328 feet (100 meters) ahead of your vehicle. For more information on the radar sensor, see page 464. Important Safety Precautions As with any system, there are limits to ACC. Inappropriate use of ACC can result in a serious accident. Use the brake pedal whenever necessary, and always keep a safe distance between your vehicle and other vehicles. Do not use ACC under these conditions: ● In poor visibility. In heavy traffic. When you must slow down and speed up repeatedly. On winding roads. When you enter a toll gate, interchange, service area, parking area, etc. In these areas, there is no vehicle ahead of you, but ACC would still try to accelerate to your set speed. In bad weather (rain, fog, snow, etc.) On a slippery road (for example a road covered with ice or snow). Features ● ● ● ● ● ● CONTINUED 349
