Collision Avoidance and Parking Assist Systems: Description and Operation

OBJECT DETECTION DESCRIPTION AND OPERATION

The object alarm detection system senses how close the vehicle is to an object. The distance is determined by the 4 ultrasonic sensors located in the rear and front (if equipped) bumpers. The object detection system will notify the driver when backing up or moving forward while parking at speeds less than 8 km/h (5 mph), which make parking easier and helps you avoid colliding with objects such as parked vehicles. The object detection system will use front and rear display indicators and the radio speakers for notification.

Front Object Alarm Detection System
When the ignition is ON and the vehicle is placed into drive, the object detection system performs a bulb check. During the bulb check, the display is located in the top of the I/P will illuminate all 3 indicators for approximately 2 seconds to indicate that the system is working. This display can assist the driver on close an object is to the front bumper. The object detection system performs a bulb check and operates when the following conditions are present:
- The ignition is ON.
- The vehicle is placed in DRIVE (D) for front parking aid.
- The vehicle speed is less than 5 km/h (3 mph). At speeds greater than 5 km/h (3 mph), the object alarm detection system is disable. The red indicator flashes to warn the driver that the object detection system is disabled.

Rear Object Alarm Detection System
When the ignition is ON and the vehicle is placed into reverse, the object detection system performs a bulb check. During the bulb check, the 3 indicators on the rear display will illuminate for approximately 2 seconds to indicate that the system is working. The object detection system performs a bulb check and operates when the following conditions are present:
- The ignition is ON.
- The vehicle is placed in REVERSE (R) for rear parking aid.
- The vehicle speed is less than 5 km/h (3 mph). At speeds greater than 5 km/h (3 mph), the object detection system is disable. The red indicator flashes to warn the driver that the object detection system is disabled.

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.
