NORMAL OPERATING CONDITION
DescriptionINFOID:0000000003774368
XENON HEADLAMP
 Brightness and the color of light may change slightly immediately after turning the headlamp ON until the
xenon bulb becomes stable. This is normal.
 Illumination time lag may occur between right and left. This is normal.
AUTO LIGHT SYSTEM
The headlamp may not be turned ON/OFF immediately after passing dark area or bright area (short tunnel,
sky bridge, shadowed area etc.) while using the auto light system. This causes for the control difference. This
is normal.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003813382
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIRBAG” and “SEAT BELT” of this
Service Manual.
WARNING:
 To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Precautions For Xenon Headlamp ServiceINFOID:0000000003773614
WARNING:
Comply with the following warnings to prevent any serious accident.
 Disconnect the battery cable (negative terminal) or the power supply fuse before installing, remov-
ing, or touching the xenon headlamp (bulb included). The xenon headlamp contains high-voltage
generated parts.
 Never work with wet hands.
 Check the xenon headlamp ON-OFF status after assembling it to the vehicle. Never turn the xenon
headlamp ON in other conditions. Connect the power supply to the vehicle-side connector.
(Turning it ON outside the lamp case may cause fire or visual impairments.)
 Never touch the bulb glass immediately after turning it OFF. It is extremely hot.
CAUTION:
Comply with the following cautions to prevent any error and malfunction.
 Install the xenon bulb securely. (Insufficient bulb socket installation may melt the bulb, the connec-
tor, the housing, etc. by high-voltage leakage or corona discharge.)
 Never perform HID circuit inspection with a tester.
 Never touch the xenon bulb glass with hands. Never put oil and grease on it.
 Dispose of the used xenon bulb after packing it in thick vinyl without breaking it.
 Never wipe out dirt and contamination with organic solvent (thinner, gasoline, etc.).

HEADLAMP AIMING ADJUSTMENT
DescriptionINFOID:0000000003774534
PREPARATION BEFORE ADJUSTING
NOTE:
 For details, refer to the regulations in your own country.
 Perform aiming if the vehicle front body has been repaired and/or the headlamp assembly has been
replaced.
Before performing aiming adjustment, check the following.  Adjust the tire pressure to the specification.
 Fill with fuel, engine coolant and each oil.
 Maintain the unloaded vehicle condition. (Remove luggage from the passenger compartment and the trunk
room.)
NOTE:
Do not remove the temporary tire, jack and on-vehicle tool.
 Wipe out dirt on the headlamp.
CAUTION:
Never use organic solvent (thinner, gasoline etc.)
 Ride alone on the driver seat.

Aiming Adjustment Procedure (Low Beam)
INFOID:0000000003774533
1. Place the screen.
NOTE:
 Stop the vehicle at the perpendicular angle to the wall.
 Set the screen so that it is perpendicular to a level load surface.
2. Face the vehicle squarely toward the screen and make the distance between the headlamp center and
the screen 10 m (32.8 ft).
3. Start the engine and illuminate the headlamp (LO).
NOTE:
Block light from the headlamp that is not being adjusted with a thick fabric or another object, so that it
does not reach the adjustment screen.
CAUTION:
Do not cover lens surface with tape, etc. because it is made from plastic.
4. Use the aiming adjustment screw to adjust the elbow point projected by the low beams on the screen, so
that it is within the aiming adjustment area.
