Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951582
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
General precautions fo r service operationsINFOID:0000000009463538
• Do not work with wet hands.
• The xenon headlamp system includes a high voltage generating
part. Be sure to disconnect batte ry negative cable (negative termi-
nal) or power fuse before removing, installing, or touching the
xenon headlamp (including lamp bulb).
• Turn the lighting switch OFF before disconnecting and connecting the connector.
• When turning the xenon headlamp on and while it is illuminated, do
not touch the harness, bulb, and socket of the headlamp.
• When checking the headlamp on/off operation, check it on vehicle and with the power connected to the vehicle-side connector.
• Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not touch the headl amp bulb just after the headlamp is turned off, because
it is very hot.
• Install the xenon headlamp bulb socket co rrectly. If it is installed improperly, high-voltage leak or corona dis-
charge may occur that can melt the bulb, connector or housing. Do not illuminate the xenon headlamp bulb
out of the headlamp housing. Doing so can cause fire and harm your eyes.
• When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
• Leaving the bulb removed from the headlamp housing for a long period of time can deteriorate the perfor- mance of the lens and reflector (dirt, clouding). Al ways prepare a new bulb and have it on hand when replac-
ing the bulb.
• When adjusting the headlamp aiming, turn the aiming adjus tment screw only in the tightening direction. If it
is necessary to loosen the screw, first fully loosen the screw, and then turn it in the tightening direction.
• Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

(WITH XENON TYPE)
HEADLAMP SYSTEM : System DescriptionINFOID:0000000009463544
XENON HEADLAMP
A Xenon type headlamp is adapted to the low beam headlamps. Xenon bulbs do not use a filament. Instead,
they produce light when a high voltage current is pa ssed between two tungsten electrodes through a mixture
of xenon (an inert gas) and certain other metal halides. 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 advantages of the xenon type headlamp.
• The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.
• Light output is nearly double that of halogen headl amps, affording increased area of illumination.
• The light features a high relative spectral distributi on at wavelengths to which the human eye is most sensi-
tive. This 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.
LOW BEAM OPERATION
When the lighting switch is in 2nd position, the BCM receives input requesting the headlamps to illuminate.
This input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the IPDM E/R
controls the headlamp low relay coil which supplies power to the low beam headlamps.

FRONT FOG LAMP
Aiming AdjustmentINFOID:0000000009463618
PREPARATION BEFORE ADJUSTING
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment procedure, check the following:
• Ensure all tires are inflated to correct pressure.
• Place vehicle and screen on level surface.
• Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
• Coolant and engine oil filled to correct level, and fuel tank full.
• Remove cargo and/or luggage to maintain an unloaded vehicle condition.
• Confirm spare tire, jack and tools are properly stowed.
• Carefully wipe off any dirt from headlamp lens. CAUTION:
Do not use organic solvent (thinner, gasoline etc.)
• Place a driver or equivalent weight of 68.5 kg (150 lb) on the driver seat.
• By hand, bounce the front and rear of the vehicle to settle the suspension and eliminate any static load.
• Place the front tires in the straight ahead position.
• Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
NOTE:
• For headlamp aiming details, refer to regulations in your area.
• By regulation, no means for horizontal aim adjustment is provided from the factory; only vertical aim is
adjustable.
• Use adjusting screw to perform aiming adjustment.
• Perform headlamp aiming if:
- The vehicle front body has been repaired.
- The front combination lamp has been removed or replaced.
- Any outfitting has been installed.
- The vehicle’s standard load condition has been substantially increased.
Aiming Adjustment Procedure
1. Place the screen. NOTE:
• Stop the vehicle facing the wall.
• Place the board on a plain road vertically.
2. Face the vehicle with the screen. Maintain 7.62 m (25.0 ft) between the front fog lamp center and the
screen.
3. Start the engine. Turn the front fog lamp ON. NOTE:
Shut off the headlamp light with the board to prevent from illuminating the adjustment screen.
CAUTION:
Do not cover the lens surface with a tape etc. The lens is made of resin.
