2. Check if the high beam shining onto the screen is at the
standard value.
Standard value:
(Vertical and horizontal direction)
The center of high intensity zone is on the
point of intersection of line (H) and line (V).
Limit:
(Vertical direction) - 0.5_of the point of
intersection of line (H)
(Horizontal direction)±0.5_of the center
of line (V)
3. Alternately turn the adjusting screw to adjust the headlamp
high beam aiming.
Caution
Be sure to adjust the aiming adjustment screw in
the tightening direction.

1. The headlamps should be aimed with the proper beam
setting equipment, and in accordance with the equipment
manufacture’s instructions.
NOTE
If there are any regulations pertinent to the aiming of
headlamps in the area where the vehicle is to be used,
adjust so as to meet those requirements.
2. Alternately turn the adjusting screw to adjust the headlamp
aiming. (Refer to P.54A-24.)

HEADLAMP INTENSITY MEASUREMENT
1. Using a photometer, and following its manufacture’s
instruction manual.
2. Maintain an engine speed of 2,000 r/min., with the battery
in the charging condition
3. Set the headlamps to high beam
4. Measure the headlamp centre intensity (a point of H line
and V line) and check to be sure that the limit value
is satisfied.
Limit:
High beam 30,000 cd or more per one headlamp
NOTE
1. There may be special local regulations pertaining to
headlamp intensity, be sure to make any adjustments
necessary to satisfy such regulations.
2. If an illuminometer is used to make the measurements,
convert its values to photometer values by using the
following formula.
I=Er
2Where:
I=intensity (cd)
E=illumination (lux)
r=distance (m) from headlamps to illuminometer
Caution
1. On the headlamp not yet adjusted, perform aiming
with connector removed and the lamps switched off,
if applicable. In addition, care should be taken to
prevent a change of optical axis when connector is
reconnected.
2. Plastic outer lens are equipped with headlamps. When
lens surface is covered with materials for not
penetrating light, headlamp operation time should be
within 3 minutes. In addition, masking such as taping
should not be performed.
HEADLAMP BULB (LOW BEAM)REPLACEMENT
(1) Disconnect battery.
(2) Disconnect connector.
(3) Screw out socket to pull out bulb.
(4) After bulb is replaced, properly reconnect connector.
Caution
Do not touch bulb surface bare-handed or with dirty
gloves. If dirt is attached on glass surface of the bulb,
immediately use alcohol or thinner to remove dirt, and
install the bulb after well dried.

HEADLAMP AUTO CUT ADJUSTMENT
PROCEDURE
Headlamps are controlled smart wiring system (SWS). For
adjustment procedure of headlamp auto lamp and headlamp
auto cut, refer to GROUP 54B.
HEADLAMP AUTO CUT FUNCTION CHECK
When lighting switch is turned ON (to HEAD position) with
ignition switch removed from ignition key cylinder and driver’s
door is opened, ensure that headlamps are switched off after
one second. When headlamps are inoperative, perform
troubleshooting. (Refer to GROUP 54B.)
