FOR USA AND CANADA

FOR USA AND CANADA : Precaution for Supplemental Restraint System (SRS) "AIR
BAG" and "SEAT BELT PRE-TENSIONER"

INFOID:0000000004676679

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 AIRBAG” and “SEAT BELT” of this
Service Manual.

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 AIRBAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors while ignition switch is
ON or engine is running, never use air or electric power tools or strike near the sensor(s) with a hammer.
Heavy vibration may activate the sensor(s), deploy the airbag(s), possibly cause serious injury.
When using air or electric power tools or hammers, always turn OFF ignition switch, disconnect the battery,
and wait 3 minutes or more before performing any service.

< PRECAUTION >

[WITH 7 INCH DISPLAY]

PRECAUTIONS

• 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.).

Working with HFC-134a (R-134a)

INFOID:0000000003470469

CAUTION:

• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. Compressor mal-

function is likely to occur if the refrigerants are mixed, refer to “CONTAMINATED REFRIGERANT”
below. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refriger-
ant Recovery/Recycling Recharging equipment and Refrigerant Identifier.

• Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo-

nents. Compressor malfunction is likely to occur if lubricant other than that specified is used.

• The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol-

lowing handling precautions must be observed:

- Immediately cap (seal) immediately the component to minimize the entry of moisture from the atmo-

sphere when removing refrigerant components from a vehicle.

- Never remove the caps (unseal) until just before connecting the components when installing refrig-

erant components to a vehicle. Connect all refrigerant loop components as quickly as possible to
minimize the entry of moisture into system.

- Use only the specified lubricant from a sealed container. Immediately reseal containers of lubricant.

Lubricant becomes saturated with moisture and should not be used without proper sealing.

- Never allow lubricant (NISSAN A/C System Oil Type S) to come in to contact with styrene foam parts.

Damage may result.

CONTAMINATED REFRIGERANT

Take the appropriate steps shown below if a refrigerant other than pure HFC-134a (R-134a) is identified
in a vehicle:
• Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant into

the atmosphere.

• Explain that recovery of the contaminated refrigerant could damage service equipment and refrigerant sup-

ply.

• Suggest the customer return the vehicle to the location of previous service where the contamination may

have occurred.

• If repairing, recover the refrigerant using only dedicated equipment and containers. Never reintroduce

contaminated refrigerant into the existing service equipment. Contact a local refrigerant product retailer
for available service if the facility does not have dedicated recovery equipment. This refrigerant must be dis-
posed of in accordance with all federal and local regulations. In addition, replacement of all refrigerant sys-
tem components on the vehicle is recommended.

• The air conditioner warranty is void if the vehicle is within the warranty period. Please contact Nissan Cus-

tomer Affairs for further assistance.

General Refrigerant Precaution

INFOID:0000000003470470

WARNING:

• Never breathe A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose or throat.

Remove HFC-134a (R-134a) from the A/C system, using certified service equipment meeting require-
ments of SAE J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [HFC-134a (R-134a) recov-
ery equipment]. Ventilate the work area before resuming service if accidental system discharge
occurs. Additional health and safety information may be obtained from refrigerant and lubricant
manufacturers.

• Never release refrigerant into the air. Use approved recovery/recycling equipment to capture the

refrigerant each time an air conditioning system is discharged.

• Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air

conditioning system.

• Never store or heat refrigerant containers above 52

C (126

F).

• Never heat a refrigerant container with an open flame. Place the bottom of the container in a warm

pail of water if container warming is required.

• Never intentionally drop, puncture, or incinerate refrigerant containers.

PRECAUTIONS

VTL-73

< PRECAUTION >

[WITH 7 INCH DISPLAY]

VTL

• Keep refrigerant away from open flames. Poisonous gas is produced if refrigerant burns.
• Refrigerant displaces oxygen, therefore be certain to work in well ventilated areas to prevent suffo-

cation.

• Never pressure test or leakage test HFC-134a (R-134a) service equipment and/or vehicle air condi-

tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
have proven to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or
property damage. Additional health and safety information may be obtained from refrigerant manu-
facturers.

Refrigerant Connection

INFOID:0000000003470471

A new type refrigerant connection has been introduced to all refrigerant lines except the following locations.
• Expansion valve to evaporator
• Refrigerant pressure sensor to liquid tank

O-RING AND REFRIGERANT CONNECTION

CAUTION:

The new and former refrigerant connections use different O-ring configurations. Never confuse O-
rings since they are not interchangeable. Refrigerant may leak at the connection if an incorrect O-ring
is installed.

PRECAUTIONS

WARNING:

Check that all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than the atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove
it.

CAUTION:

Observe the following items when replacing or cleaning refrigerant cycle components.
• Store it in the same way as 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.

• Always use a torque wrench and a back-up wrench when connecting tubes.
• Immediately plug all openings to prevent entry of dust and moisture after disconnecting tubes.
• Connect the pipes at the final stage of the operation when installing an air conditioner in the vehicle.

Never remove the seal caps of pipes and other components until just before they are 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.

• Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
• Always replace used O-rings.
• Apply lubricant to the circle of the O-rings shown in illustration when a connecting tube. Never apply

lubricant to threaded portion.

• O-ring must be closely attached to the groove portion of tube.
• Never 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 the tube correctly.

Service Equipment

INFOID:0000000003470472

RECOVERY/RECYCLING EQUIPMENT

Be certain to follow the manufacturer instructions for machine operation and machine maintenance. Never
introduce any refrigerant other than that specified into the machine.

ELECTRICAL LEAK DETECTOR

Be certain to follow the manufacturer instructions for tester operation and tester maintenance.

VACUUM PUMP

The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric pres-
sure. So the vacuum pump lubricant may migrate out of the pump
into the service hose. This is possible when the pump is switched
OFF after evacuation (vacuuming) and the hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as per the following procedure.
• Vacuum pumps usually have a manual isolator valve as part of the

pump. Close this valve to isolate the service hose from the pump.

• Use a hose equipped with a manual shut-off valve near the pump

end for pumps without an isolator. Close the valve to isolate the
hose from the pump.

• Disconnect the hose from the pump if the hose has an automatic

shut-off valve. As long as the hose is connected, the valve is open
and lubricating oil may migrate.

Some one-way valves open when vacuum is applied and close
under the no vacuum condition. Such valves may restrict the ability
of the pump to create a deep vacuum and are not recommended.
