PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006225828
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. 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” 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 that 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 “SRS AIR BAG”.
 Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT use air or electric 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 3 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation after Battery Disconnect
INFOID:0000000006225829
NOTE:
 Before removing and installing any control units, first tu rn the push-button ignition switch to the LOCK posi-
tion, then disconnect bot h battery cables.
 After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnos is according to self-diagnosis results.
For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and
cannot be turned.
If turning the steering wheel is required with the bat tery disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Turn the push-button ignition switch to ACC position. (At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock wi ll remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.

Precautions For Xenon Headlamp ServiceINFOID:0000000006225830
WARNING:
Comply with the follow ing warnings to prevent any serious accident.
 Disconnect the battery cable (neg ative 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 assem bling it to the vehicle. Never turn the xenon
headlamp ON in other conditions. Connect th e power supply to the vehicle-side connector.
(Turning it ON outside the lamp case m ay cause fire or visual impairments.)
 Never touch the bulb glass immediately afte r turning it OFF. It is extremely hot.
CAUTION:
Comply with the follow ing cautions to prevent an y error and malfunction.
 Install the xenon bulb securely. (I nsufficient bulb socket installation may melt the bulb, the connec-
tor, the housing, etc. by high-vol tage leakage or corona discharge.)
 Never perform HID circuit inspection with a tester.
 Never touch the xenon bulb glass with ha nds. Never put oil and grease on it.
 Dispose of the used xenon bulb after p acking it in thick vinyl without breaking it.
 Never wipe out dirt and cont amination with organic solven t (thinner, gasoline, etc.).
WorkINFOID:0000000006225831

 When the BCM detects that the Intelligent Key is within the outside key antenna detection area. BCM trans-
mits the request signal to the Intelligent Key and check it is near the door.
 Intelligent Key receives the request signal and transmits the key ID signal to the BCM via remote keyless
entry receiver.
 BCM receives the key ID signal and compares it with the registered key ID.
 BCM illuminates lamps that are set, when key ID verification is OK.
TIMER FUNCTION
BCM can operate welcome light function, using the timer function, for 9 days, after key switch is turned OFF.
The timer function resets when the engine is started
*.Operating period of timer function may differ depending
on battery size.
*: Timer function does not stop if another Intelligent Key that has a different key ID is detected within the inte-
rior antenna detection area, when starting the engine.
OPERATION CONDITION
If the following condition are satisfi ed, welcome light function is operated.
OUTSIDE KEY ANTENNA DETECTION AREA
The outside key antenna detection area of door lock/unlock function
is in the range of approximately 80 cm (31.50 in) surrounding the
driver, passenger door handles (1) and back door handle (2). How-
ever, this operating range depends on the ambient conditions.
WELCOME LIGHT FUNCTION SETTING
Welcome light function operation mode can be changed using CONSULT-III
With CONSULT-III
Refer to DLK-41, "
INTELLIGENT KEY : CONSULT-III F unction (BCM - INTELLIGENT KEY)".
Without CONSULT-III
The welcome light function ON/OFF can be s witched by performing the following operation.
1. Turn ignition switch: OFF →ON
2. Press and hold the driver side door request switch for 5 seconds or more within 20 seconds after turning the ignition switch ON.
3. The switching is complete when combination meter buzzer sounds.
