HEADLAMP AIMING

M1540100500542

<USING A BEAM SETTING EQUIPMENT>

1. The headlamps should be aimed with the proper 

beam setting equipment, and in accordance with 
the equipment manufacture’s instructions.

2. Alternately turn the adjusting screw to adjust the 

headlamp aiming.

<USING A SCREEN>

PRE-AIMING INSTRACTION
1. Inspect for badly rusted or faulty headlamp 

assemblies.

2. These conditions must be corrected before a 

satisfactory adjustment can be made.

3. Inspect tyre inflation, and adjust if it is necessary.
4. If the fuel tank is not filled up, put weight in the 

luggage compartment to make up for the fuel 
shortage so that the weight will become 90% of 
full-state weight or heavier. (0.8 kg per litter)

5. There should be no other load in the vehicle other 

than driver or substituted weight of approximately 
75 kg placed in driver's position.

6. Put the headlamp levelling switch in "0" position.
7. Thoroughly clean the headlamp lenses.

8. Place the vehicle on a level floor, perpendicular to 

a flat screen 3 m away from the bulb centre-marks 
on the headlamp lens.

9. Rock vehicle sideways to allow vehicle to assume 

its normal position.

10.Bounce the front suspension through three 

oscillations by applying the body weight to hood 
or bumper.

11.Run the engine at a speed of 2,000 r/min to 

charge the battery.

12.Four lines of adhesive tape (or equivalent 

markings) are required on screen or wall:
(1) Position a vertical tape or mark so that it is 

aligned with the vehicle centre line.

(2) Measure the distance from the bulb centre 

position to the floor. Transfer the 
measurement to the screen. Horizontal tape or 
mark on the screen is for reference of vertical 
adjustment.

(3) Measure the distance from the centre line of 

the vehicle to the centre of each headlamp. 
Transfer the measurement to the screen. 
Vertical tape or mark on the screen with 
reference to the centre line of each headlamp 
bulb.

HEADLAMP ADJUSTMENT

CAUTION

• Do not cover a headlamp for more than three 

minutes to prevent the plastic headlamp lens 
deformation.

• Be sure to adjust the aiming adjustment 

screw in the tightening direction.

1. The low-beam headlamp should project on the 

screen upper edge of the beam (cut-off).

2.

If not the case, turn the adjusting screws to achieve 

the specified low-beam cut-off location on the 
aiming screen.

LUMINOUS INTENSITY MEASUREMENT

M1540100600259

Using a photometer, and following its manufacture’s 
instruction manual, measure the headlamp intensity 
and check to be sure that the limit value is satisfied.

Limit: 30,000 cd or more (When a screen is 
set 25m ahead of the vehicle)

NOTE: 

.

1. When measuring the intensity, maintain an 

engine speed of 2,000 r/min, with the battery in 
the charging condition.

2. There may be special local regulations pertaining 

to headlamp intensity, be sure to make any 
adjustments necessary to satisfy such regula-
tions.

3. Check that the headlamp intensity of the high-

beam satisfies the limit value.

4. If an illuminometer is used to make the measure-

ments, convert its values to photometer values by 
using the following formula.
I = Er

:

I=intensity (cd)
E=illumination (lux)
r=distance (m) from headlamps to illuminome-
