Depending on the model variant, the vehicle may be equipped with rear object detection. Rear object detection consists of rear object alarm sensors in the rear bumper, a rear object alarm module and a rear object alarm mounted behind the rear window shelf trim panel.

The object alarm sensors fitted to the vehicle are of the ultrasonic type. The object alarm sensors transmit ultrasonic radio waves which are reflected back to the object alarm sensors at different rates depending on the detected objects distance from the object alarm sensors. This change in signal is sent to the rear object alarm module, which in turn activates the rear object alarm. On high features vehicles it also sends a signal to the infotainment unit via the GMLAN. The infotainment unit not only provides an audible warning, but also a graphic display.

To activate the object detection system the following criteria must be met:

Important: Once object detection is selected an audible confirmation tone will sound. If a confirmation tone does not sound there may be an object detection malfunction.

Note If an attached object is detected, the object detection automatically deactivates completely, approximately 10 seconds after the vehicle’s forward speed exceeds 15 km/h. The object detection will be reactivated automatically when the object is removed or the ignition is switched OFF and then ON again.

When a trailer hitch is fitted, the object detection can be adjusted to ensure that the trailer hitch is not detected as an object. This is achieved by adjusting the object detection sensor parameters for the extra length.

Important: This adjustment is for manufacturer approved trailer hitches. If a different trailer hitch is fitted, the system may detect it as an attached object and will be deactivated.

Enter the Customisation menu in the infotainment unit and select Tow Bar Att , Select Yes if a tow ball tongue/neck is attached or No if a tow ball tongue/neck is removed.
