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.

Driven content

Bending lamp LH

The LH-side bending lamp illuminates for 10
seconds.

Bending lamp RH

The RH-side bending lamp illuminates for
10 seconds.

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).

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

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

ter

HEADLAMP AUTOMATIC SHUTDOWN
FUNCTION CHECK

M1540100800145

Confirm that the headlamps turn OFF in one second
if the ignition key is pulled out and the driver's door is
opened when the ignition switch is ON and the light-
ing switch is ON (HEAD position). If there is a mal-
function, perform the troubleshooting (Refer to ).

HEADLAMP AUTO LAMP FUNCTION
CHECK

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
switch in the "ON" position and the lighting switch in
the "AUTO" position. If there is a malfunction, per-
form the troubleshooting (Refer to ).
