Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001161414
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 SRC 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 SRC 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.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001161415
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions For Xenon Headlamp ServiceINFOID:0000000001161416
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.).

Precaution for Procedure without Cowl Top CoverINFOID:0000000001162744
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
On Board Diagnostic (OBD) System of EngineINFOID:0000000001162745
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver of
a malfunction causing emission deterioration.
CAUTION:
 Be sure to turn the ignition switch OFF and disconnect the battery negative cable before any repair
or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will
cause the MI to light up.
 Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
 Certain systems and components, especially those related to OBD, may use a new style slide-lock-
ing type harness connector. For description and how to disconnect, refer to XX-XX, "*****"
.
 Be sure to route and secure the harnesses properly after work. The interference of the harness with
a bracket, etc. may cause the MI to light up due to the short circuit.
 Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to the malfunction of the fuel system, etc.
 Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM before
returning the vehicle to the customer.
