PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003533330
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:
• 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 section.
• 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.
General precautions for service operationsINFOID:0000000003533331
• Never work with wet hands.
• 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).
• Turn the lighting switch OFF before disconnecting and connecting
the connector.
• When turning the xenon headlamp on and while it is illuminated,
never 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 headlamp bulb just after the headlamp is turned off, because
it is very hot.
• 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.
• When the bulb has burned out, wrap it in a thick vinyl bag and dis-
card. Do not break the bulb.
• Leaving the bulb removed from the headlamp housing for a long
period of time can deteriorate the performance of the lens and
reflector (dirt, clouding). Always prepare a new bulb and have it on
hand when replacing the bulb.
• Do not use organic solvent (paint thinner or gasoline) to clean
lamps and to remove old sealant.

HEADLAMP (FOR USA)
• to BCM terminal 38.
Ground is supplied
• to BCM terminal 67
• through grounds M57, M61 and M79, and
• to IPDM E/R terminals 38 and 59
• through grounds E9, E15 and E24.
Low Beam Operation
With the lighting switch 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 con-
trols the headlamp low relay coil. When energized, this relay directs power
• through 15A fuse (No. 41, located in the IPDM E/R)
• through IPDM E/R terminal 54
• to front combination lamp RH terminal 5, and
• through 15A fuse (No. 40, located in the IPDM E/R)
• through IPDM E/R terminal 52
• to front combination lamp LH terminal 5.
Ground is supplied
• to front combination lamp LH and RH terminal 1
• through grounds E9, E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input request-
ing the headlamp high beams to illuminate. This input is communicated to the IPDM E/R across the CAN com-
munication lines. The CPU of the combination meter controls the ON/OFF status of the HIGH BEAM indicator.
The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power
• through 10A fuse (No. 34, located in the IPDM E/R)
• through IPDM E/R terminal 56
• to front combination lamp RH terminal 6, and
• through 10A fuse (No. 35, located in the IPDM E/R)
• through IPDM E/R terminal 55
• to front combination lamp LH terminal 6.
Ground is supplied
• to front combination lamp LH and RH terminal 2
• through grounds E9, E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
XENON HEADLAMP
Xenon type headlamp is adopted to the low beam headlamps. Xenon bulbs do not use a filament. Instead,
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.
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 headlamps, affording increased area of illumination.
• The light features a high relative spectral distribution 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.
BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lighting
switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps
are turned off.
AUTO LIGHT OPERATION
