Headlight Aiming
PRE-AIMING INSTRUCTIONS1. Test dimmer switch operation.
2. Observe operation of high beam light mounted in instrument cluster.
3. inspect for badly rusted or faulty headlight assemblies. These conditions must be corrected before a satisfactory adjustment can be made.
4. Place vehicle on a level floor.
5. Bounce front suspension through three (3) oscillations by applying body weight to hood or bumper.
6. Inspect tire inflation.
7. Rock vehicle sideways to allow vehicle to assume its normal position.
8. If fuel tank is not full, place a weight in trunk of vehicle to simulate weight of a full tank [3 kg (6.5 Ibs.) per gallon].
9. There should be no other load in the vehicle other than driver or substituted weight of approximately 70 kg (150 lbs.) placed in driver's position.
10. Thoroughly clean headlight lenses.
Horizontal Adjustment:
HORIZONTAL ADJUSTMENT
1. Check to see that the right and left indicators are visible in the viewing port.
2. Turn horizontal screw on side of headlight until the red lines are aligned. To remove "backlash", make final adjustment by turning adjusting screw in a clockwise direction.
3. Repeat the last three steps on opposite headlight.
Vertical Adjustment:
VERTICAL ADJUSTMENT
1. Check the level bubble through the viewing port.
2. Turn vertical adjusting screw until the level bubble is centered between the lines.
3. Repeat the last two steps on the opposite headlight.
AIMING WITH SCREEN
Aiming With Screen: Step (1):
HEADLIGHT AIM PREPARATION
1. Measure the center of the headlight bulb as shown in the illustration.
Aiming With Screen: Step (2):
2. Place vehicle on a known level floor 7.6 m (25 feet) from aiming screen or light colored wall. Four lines of adhesive tape or like are required on screen or wall:
a. Position a vertical tape so that it is aligned with the vehicle center line.
b. Position a horizontal tape with reference to center line of headlight bulb.
c. Position a vertical tape on the screen with reference to the center line of each of headlights bulb.
Visual Headlight Adjustment: Step (1) & (2):
VISUAL HEADLIGHT ADJUSTMENT
1. A properly aimed lower beam will appear on the aiming screen 7.6 m (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.
Visual Headlight Adjustment: Step (3):
3. Check the position of the level bubble through the window of the upper part of the headlight to confirm that it is within the range as shown in the illustration.
Visual Headlight Adjustment: Step (4) & (5):
4. Check the right and left indicators through the window of the upper part of the headlight to confirm that the red lines are aligned.
5. If the red lines are not aligned, turn the adjustments of the right and left indicators to align them.
NOTE:
If the visual headlight adjustment at low beam is made, the adjustment at high beam is not necessary.
LUMINOUS INTENSITY MEASUREMENT
Measure the luminous intensity of headlights with a photometer in accordance with the instruction manual prepared by the manufacturer of the photometer and make sure that the luminous intensity is within the following limit.
Limit: 20,000 cd or more
NOTES:
a. When measuring the luminous intensity of headlight, keep the engine at 2,000 rpm and have the battery charged.
b. 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.
