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.

Headlight Leveling Warning Light CheckS6RW0D9204015
1) Turn ignition switch to ON position.
2) Check that headlight leveling warning light (1) lights for about 2 seconds and then goes OFF. If the headlight
leveling warning light lights up again 10 seconds after it turned off, go to “Headlight Auto Leveling System
Symptom Diagnosis (If Equipped)”. If headlight leveling warning light flashes, go to “Initialization of Headlight Auto
Leveling System”.
