Elevation System Check
- Parking aid system must be inspected to ensure system does not receive signals from ground reflections. Perform elevation system check with vehicle on 10 x 15 ft. (3.1 x 4.6 m) smooth concrete surface. Area should be free of obstacles, and noise from fans and pneumatic equipment.
- Turn ignition switch to RUN position. Set parking brake, and place shift lever in Reverse. No audible alerts should be heard. If no audible alerts are heard, system is operating correctly. If audible alerts are heard, ensure bumper is properly installed and is not tilting downward so sensors are pointing at ground.
