PRECAUTIONS
PRECAUTIONS PFP:00011
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" AKS004D3
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 and SB section of this Service Man-
ual.
WARNING:
q 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 per-
formed by an authorized NISSAN/INFINITI dealer.
q Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
q 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
harness connectors.
General Precautions for Service Operations AKS002EU
q Never work with wet hands.
q Xenon headlamp includes high voltage generating part. Be sure
to disconnect battery negative cable (negative terminal) or
power fuse before removing, installing, or touching the xenon
headlamp (including lamp bulb).
q Turn the lighting switch OFF before disconnecting and connect-
ing the connector.
q When turning the xenon headlamp on and while it is illuminated,
never touch the harness, bulb, and socket of the headlamp.
q When checking the headlamp on/off operation, check it on vehi- PKIA0183E
cle and with the power connected to the vehicle-side connector.
q Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not
touch the headlamp bulb just after the headlamp is turned off, because it is very hot.
q Install the xenon headlamp bulb socket correctly. If it is installed
improperly, high-voltage leak or corona discharge may occur
that can melt the bulb, connector, and housing. Do not illuminate
the xenon headlamp bulb out of the headlamp housing. Doing
so can cause fire and harm your eyes.
q When the bulb has burned out, wrap it in a thick vinyl bag and
discard. Do not break the bulb.
q Leaving the bulb removed from the headlamp housing for long
period of time can deteriorate performance of the lens and
reflector (dirt, clouding). Always prepare a new bulb and have it
on hand when replacing the bulb. PKIA2246E
q When adjusting the headlamp aiming, turn the aiming adjusting
screw only in the tightening direction. (If it is necessary to turn the screw in loosening direction, first fully
loosen the screw, and then turn it in tightening direction.)
q Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

q to headlamp relay-1 terminal 1 and headlamp relay-2 terminal 2 from headlamp battery saver control unit
terminals 2 and 8
q through headlamp battery saver control unit terminals 3 and 9, I
q through lighting switch terminals 12 and 8

HEADLAMP (FOR USA)
q through body grounds M25 and M115.
With power and ground supplied, the high beams headlamps and the HIGH BEAM indicator illuminate.
NOTE:
The lamp will be force to turn off when the driver door is opened with the ignition switch in OFF or
ACC position. (When except for lighting switch is "AUTO" position)
BATTERY SAVER CONTROL
When the ignition switch is turned from ON (or START) to OFF (or ACC) positions while headlamps are illumi-
nated, the RAP signal is supplied to terminal 10 of the headlamp battery saver control unit from BCM terminal
135.
After counting 45 seconds by the RAP signal from the BCM to headlamp battery saver control unit, the ground
supply to both terminal 1 of headlamp relay-1 and terminal 2 of headlamp relay-2 from headlamp battery saver
control unit terminals 2 and 8 is terminated.
Then the headlamps are turned off.
The headlamps are turned off when front door (driver or passenger side) is opened even if 45 seconds have
not passed after ignition switch is turned from ON (or START) to OFF (or ACC) positions while headlamps are
illuminated.
When the lighting switch is turned from OFF to 2ND after headlamps are turned to off by the battery saver con-
trol, ground is supplied
q to headlamp battery saver control unit terminals 5 and 13 from lighting switch terminal 11, and then,
q to both terminal 1 of headlamp relay-1 and terminal 2 of headlamp relay-2 from headlamp battery saver
control unit terminals 2 and 8
q through headlamp battery saver control unit terminals 3 and 9, and
q through lighting switch terminal 12.
Then headlamps illuminate again.
AUTO LIGHT OPERATION
The auto light control system has an optical sensor inside it that detects outside brightness.
When the lighting switch is in AUTO position, it automatically turns on/off the parking (clearance) lamps and
the headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details of
the setting, refer to LT-19, "SETTING CHANGE FUNCTION FOR AUTO LIGHT SYSTEM" .
When lighting switch is in "AUTO" position, ground is supplied
q to BCM terminal 14
q from lighting switch terminal 42.
When ignition switch is turn to "ON" or "START" position and
Outside brightness is darker than prescribed level, ground is supplied
q to headlamp relay-1 terminal 1
q to headlamp relay-2 terminal 2
q through headlamp battery saver control unit terminal 2, 8 and 4, 11, and
q to tail lamp relay terminal 1
q through headlamp battery saver control unit terminals 6, 14 and 4,11.
Then headlamp relay-1, 2 and tail lamp relay are energized, headlamps (low or high) and tail lamps are illumi-
nate according to switch position.
Shut Off Delay
When the lighting switch is in "AUTO" position and the ignition switch is turned from ON to OFF while the auto
light system is activated and the headlamps are illuminated, the shut off delay feature is activated for 45 sec-
onds. Headlamps lighting time can be adjusted from about 0 to 3 minutes. (This function is not applicable to
the tail lamps.)
Auto light shut off delay timer can be adjusted in seven steps. For the details of the setting, refer to LT-19,
"SETTING CHANGE FUNCTION FOR AUTO LIGHT SYSTEM" .
VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to BL-125, "VEHICLE
SECURITY (THEFT WARNING) SYSTEM" .
Revision; 2004 April LT-8 2003 M45
HEADLAMP (FOR USA)
XENON HEADLAMP
Xenon type headlamp is adopted to the low beam headlamps. Xenon bulbs do not use a filament. Instead, A
they produce light when a high voltage current is passed 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. B
Followings are some of the many advantages of the xenon type headlamp.
q The light produced by the headlamps is white color approximating to sunlight that is easy on the eyes.
q Light output is nearly double that of halogen headlamps, affording increased area of illumination. C
q 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. D
q Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
