Offered for the first time on a Chrysler Group vehicle, Adaptive Cruise Control (ACC) allows the driver to set a cruising speed and to set a specific following distance from other vehicles on the road. Available on the 2007 Chrysler 300 Limited and Chrysler 300C, ACC detects vehicles in the Chrysler 300’s path, determines their speed and automatically maintains a pre-set following distance by braking or accelerating. In addition, the system allows the use of cruise control above 25 mph without the need for the driver to reset or adjust based on traffic flow. It is designed to detect a vehicle directly ahead within a distance of 328 feet and automatically adjusts the cruise-control speed to continue moving with traffic at a set distance. However, ACC is not designed to prevent collisions, will not react to a very slow or stopped vehicle and will not bring the car to a complete stop. If the sensor does not detect a vehicle directly ahead, it functions as a standard cruise-control system, maintaining the designated speed. But when traffic speeds vary, ACC automatically adjusts to the speed of the vehicle ahead. ACC applies braking (up to 25 percent of the braking system as needed) and accelerates automatically to maintain the preset distance from the preceding vehicle.
