PrecautionINFOID:0000000005929547
• When removing or disassembling any part, be careful not to damage or deform it. Protect parts which may
get in the way with cloth.
• When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.
• Keep removed parts protected with cloth.
• If a clip is deformed or damaged, replace it.
• If an unreusable part is removed, replace it with a new one.
• Tighten bolts and nuts firmly to the specified torque.
• After re-assembly has been completed, make sure each part functions correctly.
• Remove stains in the following way.
- Water-soluble stains:
Dip a cloth in warm water, and squeeze tightly. After wiping the stain, wipe with a soft dry cloth.
- Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the
stain with the cloth. Next, dip the soft cloth in fr esh water, and then squeeze it tightly. Then clean off the
detergent completely. Then wipe the area with a soft dry cloth.
• Do not use any organic solvent, such as thinner or benzine.
• When performing procedures that require removal of the cowl top, cover the lower end of the windshield with a suitable protection
material.

Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005930910
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 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 w hether 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 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 NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect 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 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 3 minu tes before performing any service.
Precaution for Procedure without Cowl Top CoverINFOID:0000000005930912
When performing the procedure after removing cowl top cover, cover
the lower end of windshield.
Precaution for Drain CoolantINFOID:0000000005930913
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000005930914
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
