Parking Aid
WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The parking aid system sounds a warning to alert the driver of stationary objects near the rear bumper when REVERSE (R) is selected. The parking aid system assists the driver in detecting certain objects while the vehicle moves slowly in reverse at speeds less than 4.8 km/h (3 mph). The parking aid system may not detect angular or moving objects.
