HEADLAMP AIMING
M1540100500337
<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> (LOW-BEAM)
PRE-AIMING INSTRUCTION
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. Turn the headlamp levelling switch to the switch
position "0." <Vehicles with headlamp manual
levelling system>
7. Change the vehicle posture, and then operate the
actuator of headlamp levelling unit once.
<Vehicles with headlamp automatic levelling
system>
8. Thoroughly clean the headlamp lenses.

Simulated speed
Bending lamp LH/RH
The simulated vehicle speed of 30 km/h is
input to the headlamp automatic levelling-
ECU, and the bending lamp to which the
steering wheel is turned illuminates. The
bending lamp illumination duration can be
selected from 1 minute, 5 minutes or 10
minutes.

9. Place the vehicle on a level floor, perpendicular to
a flat screen 3 m away from the bulb centre
position of the low-beam.
10.Rock vehicle sideways to allow vehicle to assume
its normal position.
11.To correct for distortion of the suspension, rock
the bumpers on the front/rear side of the vehicle
up and down three times alternately.
12.Run the engine at a speed of 2,000 r/min to
charge the battery.
13.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.
NOTE: Height from the floor to the centre of
the headlamps (Reference value): 680 mm
(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.
Standard value:
Vertical direction; 36 mm (0.69
°) below hori-
zontal (H)
Horizontal direction; Elbow point intersects
the vertical line (V)
Limit:
Vertical direction;
±15 mm (±0.29°) from the
horizontal cut-off line
Horizontal direction;
± 26 mm (± 0.5°) from
the vertical line (V)

LUMINOUS INTENSITY MEASUREMENT
M1540100600163
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
2
:
I=intensity (cd)
E=illumination (lux)
r=distance (m) from headlamps to illuminome-
ter

Verify that the headlamps will illuminate when plac-
ing a hand over the light receiver of the lighting con-
trol sensor under direct sunlight with the ignition
