Adaptive cruise control

Cadillac XLR / Overview / Adaptive cruise control

The XLR will be among the first vehicles with adaptive cruise control (ACC). While not a substitute for full driver attention, this system greatly expands the convenience of cruise control. ACC uses a radar sensor mounted at the front of the car to detect objects in its path. If the lane ahead is clear, the system will maintain the set speed, just like conventional cruise control. When a vehicle is detected in the same lane in front of the car, the system will adjust vehicle speed to help maintain a constant following distance, set by the driver.

If a vehicle or object in the path of the car is stationary or moving at significantly slower speed, the system provides visible and audible alerts to the driver. ACC is set by a conventional stalk-mounted control but is monitored through a graphic representation in the head-up display.
