PRECAUTIONS
DescriptionINFOID:0000000006280865
Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.
Precaution for Supplemental Restraint S ystem (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006280866
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.
Precautions For Xenon Headlamp ServiceINFOID:0000000006280867
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 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 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. (Ins ufficient bulb socket installation may melt the bulb, the connec-
tor, the housing, etc. by high-v oltage leakage or corona discharge.)
 Never perform HID circuit in spection 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 packing it in thick vinyl without breaking it.
 Never wipe out dirt and cont amination with organic solven t (thinner, gasoline, etc.).

- Never allow lubricant (A/C System Oil Type R) to come in contact with styrene foam parts. Damage
may result.
REFRIGERANT CONNECTION
A new type refrigerant connection has been introduced to a ll refrigerant lines except the following location.
 Expansion valve to evaporator
 Refrigerant pressure sensor to liquid tank
WARNING:
Check that all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loo sen the discharge side hose fitting and remove it.
CAUTION:
Observe the following when replacing or cleaning refrigerant cycle components.
 Store it in the same way at it is when mounted on the car when the compressor is removed. Failure
to do so will cause lubricant to enter the low-pressure chamber.
 Use always a torque wrench and a b ack-up wrench when connecting tubes.
 Plug immediately all openings to prevent entry of dust and mois ture after disconnecting tubes.
 Connect the pipes at the final stag e of the operation when installing an air conditioner in the vehicle.
Never remove the seal caps of pipes and other compon ents until just before required for connection.
 Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
 Remove thoroughly moisture from the refriger ation system before charging the refrigerant.
 Replace always used O-rings.
 Apply lubricant to circle of th e O-rings shown in illustration when connecting tube. Be careful not to
apply lubricant to threaded portion.
 O-ring must be closely attached to the groove portion of tube.
 Be careful not to damage O-ring and tube when replacing the O-ring.
 Connect tube until a click can be heard. Then tighten the nut or bolt by hand. Check that the O-ring is
installed to tube correctly.
 Perform leakage test and make sure that there is no leakage from connections after connecting line.
Disconnect that line and replace the O-ring when the refrigerant leaking point is found. Then tighten
connections of seal seat to the specified torque.
COMPRESSOR
CAUTION:
 Plug all openings to prevent moisture and foreign matter from entering.
 Store it in the same way at it is when moun ted on the car when the compressor is removed.
 Follow “MAINTENANCE OF LUBRICANT LEVEL IN CO MPRESSOR” exactly when replacing or repair-
ing compressor. Refer to HA-22, "
Description".
 Keep friction surfaces between clutch and pulley cl ean. Wipe it off by using a clean waste cloth
moistened with thinner if the surface is contaminated with lubricant.
