Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001703128
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.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001844076
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
PrecautionINFOID:0000000001703129
• If transaxle assembly is removed from the vehicle, always replace CSC (Concentric Slave Cylinder).
Installed CSC returns to the original position when removing transaxle assembly. Dust on clutch disc sliding
parts may damage CSC seal, and may cause clutch fluid leakage.
• Do not reuse transaxle oil.
• Drain, fill and check transaxle oil with the vehicle on level surface.
• During removal or installation, keep inside of transaxle clear of dust or dirt.
• Check for the correct installation orientation prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts they are applied to.
• In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tight-
ening sequence is specified, follow it.
• Be careful not to damage the sliding surfaces and mating surfaces of parts.

• 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.
• Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
• Always replace used O-rings.
• When connecting tube, apply the specified A/C oil to circle of the O-rings as shown. Be careful not to
apply oil to threaded portion. Refer to MTC-88, "
Oil".
• O-ring must be closely attached to dented portion of tube.
• When replacing the O-ring, be careful not to damage O-ring and tube.
• Connect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.
• After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.
Precaution for Service of CompressorINFOID:0000000001704280
•Plug all openings to prevent moisture and foreign matter from entering.
•When the compressor is removed, store it in the same position as it is when mounted on the car.
•When replacing or repairing compressor, follow “Maintenance of Oil Quantity in Compressor”
exactly. Refer to MTC-16, "
Maintenance of Oil Quantity in Compressor" .
•Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with oil, wipe
it off by using a clean waste cloth moistened with thinner.
•After compressor service operation, turn the compressor shaft by hand more than five turns in both
directions. This will equally distribute oil inside the compressor. After the compressor is installed,
let the engine idle and operate the compressor for one hour.
•After replacing the compressor magnet clutch, apply voltage to the new one and check for usual
operation.
Precaution for Service EquipmentINFOID:0000000001704281
