PROCEDURE

1. PREPARATION FOR MILLIMETER WAVE RADAR SENSOR ASSEMBLY ADJUSTMENT

(a) Park the vehicle on a level surface where the area in front of the vehicle shown in the illustration is free of metal objects.

*a

2.5 m (8.2 ft.)

*b

2 m (6.6 ft.)

Do not place any metal objects in this area

Do not place metal objects with a height of more than 50 mm (1.97 in.) in this area

HINT:

Metal objects with a height of 50 mm (1.97 in.) or less placed within the area shown in the illustration will not affect the adjustment.

(b) Check the levelness of the ground.

(1) Check the levelness of the ground at the 3 points shown in the illustration.

*a

1.5 m (4.92 ft.)

Levelness Check Point

(2) Place the level on each levelness check point and check that the air bubble of the level is centered.

(c) Adjust the tire inflation pressure to the specified pressure.
