Cadillac 2015 - CRC manual Backing Warning and Rear Automatic Braking

9-46 Driving and Operating

The instrument cluster may have a parking assist display with bars that show “distance to object” and object location information for RPA, and on some vehicles, for the Front Parking Assist system. As the object gets closer, more bars light up and the bars change color from yellow to amber to red.

When an object is first detected in the rear, one beep will be heard from the rear, or both sides of the Safety Alert Seat will pulse two times. When an object is very close (<0.6 m (2 ft) in the vehicle rear, or <0.3 m (1 ft) in the vehicle front), five beeps will sound from the front or rear depending on object location, or both sides of the Safety

Alert Seat will pulse five times. Beeps for Front Parking Assist are higher pitched than for Rear Parking Assist.

Backing Warning and Rear Automatic Braking

Vehicles with Adaptive Cruise Control (ACC) have the Backing Warning System and Rear Automatic Braking (RAB) system. The Backing Warning part of this system can warn of rear objects when backing up at speeds greater than 8 km/h (5 mph).

The Backing Warning System will beep once from the rear when an object is first detected, or pulse twice on both sides of the Safety Alert Seat. When the system detects a potential crash, beeps will be heard from the rear, or five pulses will be felt on both sides of the Safety Alert Seat. There may also be a brief, sharp application of the brakes.

{Warning

The Backing Warning System only operates at speeds greater than 8 km/h (5 mph). It does not detect children, pedestrians, bicyclists, animals, or objects below the bumper or that are too close or too far from the vehicle. In some situations, such as at higher backing speeds, there may not be enough time for the short, sharp application of the vehicle brake system to occur. To prevent injury, death, or vehicle damage, even with the Backing Warning System, always check the area around the vehicle and check all mirrors before backing.

When the vehicle is in R (Reverse) and if it is backing too fast to avoid a crash with a detected object directly behind the vehicle, the Rear Automatic Braking (RAB) system
