Adaptive Cruise Control (ACC) — If Equipped
In this manual: STARTING AND OPERATING
~2min read
Adaptive Cruise Control (ACC) increases the driving convenience provided by cruise control when driving on highways and major roads. However, it is not a safety system and is not designed to prevent collisions. The cruise control function operates differently if your vehicle is not equipped with ACC.
NOTE:
- If the ACC sensor detects a vehicle ahead, ACC will automatically apply limited braking or acceleration (without exceeding the original set speed) to maintain the preset distance, while matching the speed of the vehicle ahead.
- Any modifications to the chassis/suspension or tire size of the vehicle will affect the performance of Adaptive Cruise Control and the Forward Collision Warning System.
- Fixed-speed cruise control only (ACC distance not set) will not detect vehicles directly ahead of you. Always remember the selected mode.
- Adaptive Cruise Control (ACC) is a convenience system. It is not a substitute for active driver involvement. It is always the driver's responsibility to stay alert, drive safely, pay attention to road, traffic and weather conditions, vehicle speed, distance to the vehicle ahead; and, most importantly, to keep the brakes working to ensure safe operation of the vehicle under all road conditions. Your full attention is always required while driving to maintain safe control of your vehicle. Failure to heed these warnings could result in collision, death or serious personal injury.
- ACC System:
- ACC does not react to pedestrians, oncoming vehicles, and stationary objects (such as a stopped vehicle in a traffic jam or a disabled vehicle).
- ACC cannot take into account road, traffic, and weather conditions and may be limited in adverse visibility conditions.
- ACC does not always fully recognize complex driving conditions, which may result in incorrect or missing distance warnings.
- On vehicles with automatic transmission, ACC will bring the vehicle to a complete stop while following the vehicle ahead, and hold the vehicle in the stopped position for two seconds. If the vehicle ahead does not begin to move within two seconds, the ACC system will display a message that the system will release the brakes and that the brakes must be applied manually. A chime will sound when the brakes are released.
- You must turn off the ACC system:
- When driving in fog, heavy rain, heavy snow, wet snow, heavy traffic, or in complex road conditions (for example, on a highway with construction zones).
- When entering a turn lane or an off-ramp; when driving on roads that are winding, icy, snow-covered, slippery, or have steep grades or slopes.
- When towing a trailer up or down a steep grade or slope.
- When conditions do not allow safe driving at a constant speed.
