AIMING WITH SCREEN
HEADLIGHT AIM PREPARATION
Place vehicle on a known level floor 7.6 (25 feet) from aiming
screen or light colored wall. Four lines of adhesive tape or like
are required on screen or wall:
1.
Position a vertical tape so that it is aligned with the vehicle
center line.
2. Position a horizontal tape with reference to center line of
headlight.
3.
Position a vertical tape on the screen with reference to the
center line of each of headlights.
VISUAL HEADLIGHT ADJUSTMENT
1. A properly aimed lower beam will appear on the aiming
screen 7.6 (25 feet) in front of the vehicle. The shaded
area as shown in the illustration indicates high intensity
zone.
2. Adjust low beam of headlights to match the low beam
pattern of the right and left headlights.
NOTE
If the visual headlight adjustment at low beam is made, the
adjustment at high beam is not necessary.

18,000 cd or more
Type II
7,000
cd or more
NOTES
When measuring the luminous intensity of headlight, keep
the engine at 2,000 rpm and have the battery charged.
If there are specific regulations for luminous intensity of
headlights in the region where the vehicle is operated,
make sure that the intensity conforms to the requirements
of such regulations.
