Precautions
Precautions for Discharge Headlight Service (If Equipped)S6RW0D9200001
WARNING!
• Do not touch igniter or ballast when lighting switch is at “HEAD” position to avoid possible electric
shock.
• Do not measure voltage or resistance with tester connected to output connector of ballast or igniter
to avoid possible electric shock.
• Do not perform work where exposed to water including rain or with wet hands to avoid possible
electric shock.
• Disassembling igniter or ballast is strictly prohibited as it may cause an electric shock.
• Before inspecting or repairing discharge headlight or its peripheral parts, make sure that lighting
switch is at OFF position and battery is disconnected at negative terminal to avoid possible
electrical shock.
• Do not set lighting switch to “HEAD” position with connector disconnected or any part removed to
avoid possible electric shock.
• Do not touch glass surface of headlight bulb. Oil or grease attached on it may not only make bulb
service life shorter but also cause bulb to burst when lighting switch is turned on.
• Mercury, metal iodide and xenon gas are sealed in discharge headlight bulb. Be sure to dispose of
used discharge headlight bulb properly according to applicable rules or regulations.

Precautions in Diagnosing Troubles (Headlight Auto Leveling System)S6RW0D9200002
• Be sure to read “Air Bag Warning in Section 00” before inspection and observe what is written there.
• Replacement of height sensor and headlight leveling control module. When height sensor and/or headlight leveling
control module is replaced with new one, perform initialization of headlight auto leveling system according to
“Initialization of Headlight Auto Leveling System”.
General Description
Discharge Headlight Description (If Equipped)S6RW0D9201001
Discharge headlight provides more brightness and consumes less electricity as compared with the conventional
halogen headlight. It consists of a ballast (1), igniter (2) and discharge headlight bulb (3).
Ballast
Ballast makes the voltage from the battery rise and converts the current from DC to AC. It also outputs high voltage to
the igniter when the headlight is turned on and supplies to discharge headlight bulb with necessary voltage for
continuous lighting while it is lit.

Igniter
Igniter generates high voltage needed to turn on the discharge headlight. It is charged with high voltage raised by the
ballast and it applies voltage pulse as high as about 20,000V to the tungsten electrode in the discharge headlight bulb.
After the discharge headlights light up, the ballast supplies voltage to bulbs.
Discharge headlight bulb
Discharge headlight bulb is used for the low beam. It does not have a filament but xenon gas (1), mercury (3) and
metal iodide (2) sealed in it. It lights up when its tungsten electrodes (4) apply high voltage to these contents.
Fail-safe function of discharge headlight
As the ballast has a fail-safe function which stops supply of the voltage to the igniter when it detects any of the
following condition.
• Ignition switch is set to “HEAD” position while igniter is not connected to discharge headlight bulb
• Discharge headlight does not light up even when lighting switch is set to “HEAD” position.
• Ballast detects a short in the circuit between discharge headlight bulb and ballast when lighting switch is at “HEAD”
position.
Headlight Auto Leveling System Description (If Equipped)S6RW0D9201002
Headlight Auto Leveling System adjusts the optical axis of the headlight automatically to be suitable for the varied
vehicle position while the headlights are lit. It consists of front height sensor (1), rear height sensor (2), headlight
leveling control module (3), headlight leveling actuator (4) and headlight leveling warning light (5).

With more passenger(s) or luggage in the vehicle, the vehicle position differs from that in such vehicle state with one
person and no load in the vehicle and angle of the headlight optical axis varies accordingly. This system automatically
adjusts the varied angle to maintain the optical axis properly.
Front and rear height sensors
Front height sensor (1) is installed to the front suspension frame (2) respectively and connected to the lower arm (4)
with the link (3). Also rear height sensor is installed to the rear floor center cross member (5) respectively and
connected to the rear axle (6) with the link (3). Each height sensor converts vertical movement of the lower arm into
the resistance value and outputs the detected change in the vehicle position as a voltage signal to the headlight
leveling control module.
Headlight leveling control module
Headlight leveling control module is installed at the inside of the glove box. It uses the headlight ON signal from the
lighting switch, vehicle speed signal from BCM and vehicle position signal from height sensors to calculate the angle
of the headlight optical axis to be corrected. Then it adjusts the optical axis angle of headlight based on the calculated
angle value by driving the headlight leveling actuator so that proper headlight aiming is obtained. Also, when any
abnormality is detected in the system, the headlight leveling control module makes the headlight leveling warning light
in the combination meter light up to warn the driver of an abnormality in the system.
Fail-safe function of headlight leveling control module
Headlight leveling control module has a fail-safe function which operates as follows.

Headlight leveling actuator
Headlight leveling actuator is (1) located in the headlight housing (2). It moves the reflector (3) in the headlight housing
according to the drive signal from the headlight leveling control module so as to adjust the optical axis of the headlight
to the angle calculated by the headlight leveling control module.
Auto-On Headlight System Description (If Equipped)S6RW0D9201003
The auto-on headlight is controlled by auto-on headlight controller (1) and works as follows.Under such conditions as
the ignition switch turned ON and the lighting switch (2) turned to the “AUTO” position, when illuminance to the auto-on
headlight sensor (3) becomes lower than the specified value, the headlights and clearance lights are turned ON by
auto-on headlight controller. On the other hand, when illuminance to the auto-on headlight sensor becomes higher
than the specified value under the same conditions, the headlights and clearance lights are turned OFF by auto-on
headlight controller.Voltage supplied to height sensor is lower
