Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine
compartment side without removing the headlamp body.

Grasp only the plastic base when handling the bulb.
Never touch the glass envelope.
1. Disconnect the battery cable.
2. Turn the bulb retaining ring counterclockwise until it is free
from the headlamp reflector, and then remove it.
3. Disconnect the harness connector from the back side of the
bulb.
4. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
5. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp reflector without bulb for a long
period of time. Dust, moisture, smoke, etc. entering head-
lamp body may affect the performance of the headlamp.
Remove headlamp bulb from the headlamp reflector just
before a replacement bulb is installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. Aimers should
be in good repair, calibrated and operated in accordance with
respective operation manuals.
If any aimer is not available, aiming adjustment can be done as
follows:
For details, refer to the regulations in your own country.
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is no-load in vehicle (coolant, engine oil
filled up to correct level and full fuel tank) other than the
driver (or equivalent weight placed in driver’s position).
CAUTION:
Be sure aiming switch is set to“0”when performing aiming
adjustment on vehicles equipped with headlamp aiming
control.

LOW BEAM
1. Turn headlamp low beam on.
2. Use adjusting screws to perform aiming adjustment.

First tighten the adjusting screw all the way and then
make adjustment by loosening the screw.

Adjust headlamps so that main axis of light is parallel to
center line of body and is aligned with point P shown in
illustration.

Figure to the above shows headlamp aiming pattern for
driving on left side of road; for driving on right side of
road, aiming pattern is reversed.

System Description
Xenon type headlamp is adopted to the low beam headlamps. Xenon bulbs do not use a filament. Instead,
they produce light when a high voltage current is passed between two tungsten electrodes through a mix-
ture of xenon (an insert gas) and certain other metal hallides. In addition to added lighting power, electronic
control of the power supply gives the headlamps stable quality and tone color.
Following are some of the many advantage of the xenon type headlamp.

The light produced by the headlamps is white color approximating sunlight that is easy on the eyes.

Light output is nearly double that of halogen headlamps, affording increased area of illumination.

The light features a high relative spectral distribution at wavelengths to the human eye is most sensitive,
which means that even in the rain, more light is reflected back from the road surface toward the vehicle,
for added visibility.

Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.

WARNING:

The xenon headlamp has a high-tension current generating area. Be extremely careful when
removing and installing. Be certain to disconnect the battery negative cable prior to removing or
installing.

When the xenon headlamp is lit, do not touch the harness (covered with red or amber insulation),
bulb itself or the bulb socket with your bare hands.

Never service a xenon headlamp with wet hands.

When checking body side harness with a circuit tester, be certain to disconnect the harness
connector from the xenon headlamp.

When the xenon headlamp is lit, the xenon bulb must be installed in the headlamp housing.
(Never turn on xenon headlamp, if the bulb is out of the headlamp housing.)
CAUTION:
Make sure to install the bulb securely; if the xenon bulb is improperly installed in its socket, high-
tension current leaks occur. This may lead to a melted bulb and/or bulb socket.

CAUTION:

After replacing a new xenon bulb, be sure to make aim-
ing adjustments.

Hold only the plastic base when handling the bulb. Never
touch the glass envelope.

Do not leave headlamp reflector without bulb for a long
period of time. Dust, moisture, smoke, etc. entering
headlamp body may affect the performance of the head-
lamp. Remove headlamp bulb from the headlamp reflec-
tor just before a replacement bulb is installed.
1. Disconnect negative battery cable.
2. Remove side combination lamp and radiator grille.
3. Disconnect headlamp connector.
4. Remove headlamp assembly.
WARNING:
Never service a xenon headlamp with wet hands.
XENON BULB (LOW BEAM)
1. Remove headlamp seal cover.
2. Turn bulb socket counterclockwise with keep pushing, then
remove it.
3. Release retaining pin.
4. Remove the xenon bulb.
5. Install in the reverse order of removal.
CAUTION:

When disposing of the xenon bulb, do not break it;
always dispose of it as is.

Make sure to install the bulb securely; if the xenon bulb
is improperly installed in its socket, high-tension current
leaks occur. This may lead to a melted bulb and/or bulb
socket.

HEADLAMP—Daytime Light System With Xenon Type—
EL-82

System Description
The auto level control unit is designed to adjust the beam angle of the headlamp in response to the load-
ing conditions of the vehicle. It is not designed to compensate for the dynamic handling of the vehicle.
The vehicle’s front and rear height is measured by sensors attached to the front stabilizer bar and the rear
suspension lateral link arm. The sensors provide a signal to the auto level control unit, which calculates the
correct headlamp aiming position and sends a signal to the aiming motors.
Initialisation
After the replacement or adjustment of any suspension sensor, the system must be self calibrated. This is
achieved as follows.
The vehicle must be empty, since any load will result in an invalid calibration. From outside of the vehicle
turn ignition on and then within 7 seconds the light switch must be turned from off to side lights on position,
5 times, finishing with the lamps in the on position.
The headlamps will then move to the highest, then the lowest then the normal position to indicate that the
calibration is successful, as can be seen by the moving beam pattern.
After successful calibration the headlamps must then be aimed in the conventional manner. Refer to EL-70.
