Parking Assist Indicators
WARNING: This page is about a different car, the 2010 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
The rear parking assist indicator is located in the interior rear of the vehicle and is visible through the inside rearview mirror. The front parking assist indicator is located on the instrument panel. Each indicator contains three LEDs: two amber and one red. The object alarm module controls these three LEDs as a visual indicator of how close the vehicle bumper is to an object. The object alarm module supplies voltage to each of the LEDs and commands each LED on by supplying an individual ground.
