Elevation System Check

WARNING: This page is about a different car, the 2004 Mercury Mountaineer and 2004 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The following system check should be carried out with the vehicle on a 4.5 meters (15 feet) wide by 3.0 meters (10 feet) deep smooth concrete surface, free of all obstacles. The area should also be free of noise from fans and pneumatic tools.

Check the parking aid system to make sure that the system does not sense signals caused by ground reflections.
