Object Alarm System Description

WARNING: This page is about a different car, the 2007 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.

The object alarm system monitors the distance and how close a vehicle is to an object when backing up in a parking maneuver. The object alarm system will notify the driver of any objects of interest when backing up at speeds less than 8 km/h (5 mph). The distance between a vehicle and an object of interest is monitored by 4 ultrasonic sensors located in the rear bumper of the vehicle. The object alarm sensors receive the echo signal reflected off an object of interest while the vehicle is backing up at speeds less than 8 km/h (5 mph). The object alarm system uses visual displays and audible warnings from the radio speakers to warn the driver of an object of interest within the defined field of view. The visual display comprises of two amber and one red indicators and these indicators illuminate based on the vehicle distance to the object of interest. When the ignition is ON and the vehicle is placed into REVERSE, the object detection system performs a bulb check on the rear display.
