Object Detection Alarm System Operation

The object detection system senses how close the vehicle is to an object. The distance is determined by the 4 ultrasonic sensors located on the front (if equipped) and rear bumper. When the system detects an object depending if the vehicle is in drive or reverse, one of the following will occur:

• If the object is less than 0.3 m (11 in) away from the vehicle, the amber outside, amber middle, and the red outside indicators flash and the chime sounds continuously.
• If the object is less than 0.3-0.5 m (11-20 in) away from the vehicle, the amber outside, amber middle, and the red outside indicators are ON and the chime sounds continuously.
• If the object is 0.5-1.0 m (20-40 in) away from the vehicle, the amber outside, and the amber middle indicators are ON.
• If the object is 1-1.5 m (40-60 in) away from the vehicle, the amber outside indicator is ON and the chime sounds one time on the first detection of an object.

Object detection system can detect objects 7.6 cm (3 in) wide and at least 25.4 cm (10 inches) tall. It cannot detect objects above the level of the roof.

If the object detection system detects a malfunction, a DTC will be stored and the object detection system will send a serial data communication message to the instrument panel (I/P) to scroll SERVICE PARK ASSIST message on the driver information center (DIC). Then the chime will sound and the red indicator on both information telltale centers will flashes continuously, notifying the driver that a malfunction exist.
