NOTE
The illustration shows L.H. drive vehicles. For R.H. drive
vehicles, it is symmetrical.
3. Alternately turn the adjusting screw to adjust the headlamp
low beam aiming.
Caution
Be sure to adjust the aiming adjustment screw in
the tightening direction.
High Beam Adjustment
1. 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 centre - marks on the
high beam headlamp lens 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 high beam headlamp.
Transfer the measurement to the screen. Vertical
tape or mark on the screen with reference to the
centre line of each high beam headlamp bulb.

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.

Inspection Procedure F-1
Except for lighting switch “OFF” the headlamps only
respond to the “low-beam” position.
Probable cause
If the headlamps only go onto low-beam regardless of the switch position, the
headlamp fail - safe function is probably activated.DColumn switch fault
