Rear Parking Assist Operation

WARNING: This page is about a different car, the 2010 Buick LaCrosse. However, it is still accessible from the selected car via links, so may be relevant.

When the vehicle is running and first placed into reverse, an audible beep will sound to indicate the system is working. The parking assist control module receives its power from the reverse light circuit.

When backing up, the system is constantly monitoring for objects of interest located behind the vehicle. The parking assist system can detect objects greater than 7.6 cm (3 in) wide and 25.4 cm (10 in) tall. The system cannot detect objects below the bumper or underneath the vehicle. If an object is detected within 2.5 m (8 ft) away from the rear bumper, there will be an audible beep out of the object alarm module. As the vehicle gets closer to an object, the time between the beeps becomes shorter. If the vehicle stops moving and there is an object within 2.5 m (8 ft) away from the rear bumper the beeping will stop after 3 seconds. When the distance between the object and the vehicle starts to decrease again the beeping will start again.

If the parking assist system detects a malfunction when the vehicle is placed into reverse (vehicle running) the parking assist control module will immediately go into a diagnostic mode which provides a different frequency beep tone.
