Adaptive Cruise Control will keep your vehicle a safe distance from the vehicle in front, should it slow or stop when you're cruising or travelling in slow-moving traffic. If the vehicle in front stops, you will come to a gradual halt.

Adaptive Cruise Control (ACC) is an advanced cruise control system that can also keep a set distance behind another vehicle. A sensor in the front of the vehicle monitors the distance and relative speed of a vehicle ahead. The ACC system then adjusts vehicle speed to maintain a driver-selected cruising speed and minimum following distance.

If the ACC system detects that the vehicle in front is slowing quickly or if another vehicle cuts in front from another lane, the system automatically applies limited braking and may alert the driver with a warning light or sound. When not following a vehicle, the ACC automatically accelerates the vehicle to the speed the driver has chosen.

More advanced systems will slow the vehicle all the way to a stop in stop-and-go traffic and automatically returns to the set speed when traffic gets moving again.

Operation
Drivers set desired speed and following distance (close, medium or far)
Standard ACC systems ranges of operation vary by manufacturer
