Elevation System Check

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

   Turn the ignition to the ON position, engine off.

2. Set the parking brake.

3. Place the gear shift in REVERSE (R).

4. Verify that no audible alerts are heard. If audible alerts are heard, check to make sure the bumper is correctly installed and is not tilted downward so that the sensor is pointing at the ground.
   • If the audible warning tone is heard, refer to Parking Aid in the Diagnosis and Testing portion of this section.
