PROCEDURE

1. SECURE APPROPRIATE AREA FOR PERFORMING LEARNING

(a) Park the vehicle on a level surface.

HINT:

  • Make sure that the target recognition area of the forward recognition camera is free of objects which may be misrecognized as a target, such as overhead lights, windows, reflective objects, etc.
  • If there are any objects which may be misrecognized as a target behind the area where a target will be placed, prepare an appropriate object to block the background.

*a

3 m (9.84 ft.)

(b) Check the levelness of the ground.

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

*a

2.2 m (7.22 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.

(d) Clean the windshield glass.

2. CREATE TARGET

NOTICE:

Do not laminate the target or attach reflective materials, such as clear adhesive tape, to its surface. If there are reflective areas on the surface of the target, they will appear white to the forward recognition camera and the target may not be recognized.
