1. Before performing the inspection, check the following items.

The inflation pressure of tires is correct.

The vehicle does not have load.

Vehicle’s fuel tank is fully filled.

2. Place the vehicle on a level surface, where approximately 5 square meters (16.41 square ft) area can be secured behind the vehicle.

4. Set up the radar reflector.

NOTE:

The following procedure explains the method of setting the radar reflector so that the distance between radar reflector and radar sensor is 1,500 mm (4.92 ft) and the radar is positioned at an angle of 50 degree.

(1) Suspend the plumb bob from the center of the front hole cap, and mark the position where the plumb bob touches the ground. (Point A)

NOTE:

Stick the packing tape etc. on the floor, then make a marking on the tape.

(3) Stretch a leveling line to draw an arc with the marked point A as a pivot.

(4) Stretch a leveling line to draw an arc with the marked point B as a pivot.

(5) Set up the radar reflector at the cross point.

CAUTION:

When setting up the radar reflector, adjust the height so that the center of the pyramid points at the radar sensor as shown in the figure.

(a)

751±10 mm (29.57±0.39 in)
