Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000012197096

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 AIR BAG” and “SEAT BELT” of this

Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.

• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, it is recommended that all maintenance

and repair be performed by an authorized NISSAN/INFINITI dealer.

• Improper repair, 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 “SRS AIR BAG”.

• 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

WARNING:

Always observe the following items for preventing accidental activation.

• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never 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 or batteries, and wait at least 3 minutes before performing any service.

- Driving for 30 minutes or more on a steep slope.

• For vehicles with the 2-batteries, be sure to connect the main battery and the sub battery before turning ON

the ignition switch.

NOTE:

If the ignition switch is turned ON with any one of the terminals of main battery and sub battery discon-

nected, then DTC may be detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:

The removal of 12V battery may cause a DTC detection error.

Precautions For Refrigerant System Service

INFOID:0000000012197099

GENERAL REFRIGERANT PRECAUTION

WARNING:

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

throat. Remove HFC-134a (R-134a) from the A/C system, using certified service equipment meeting

requirements of SAE J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [HFC-134a (R-134a)

recovery equipment]. Ventilate 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 recharging equipment to cap-

ture the refrigerant each time an air conditioning system is discharged.

PRECAUTIONS

HA-5

< PRECAUTION >

• Wear always 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.

• 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 been shown 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 refriger-

ant manufacturers.

WORKING WITH HFC-134a (R-134a)

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:

- Cap (seal) immediately the component to minimize the entry of moisture from the atmosphere 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. Reseal immediately containers of lubricant.

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

- Never allow lubricant to come in contact with styrene foam parts. Damage may result.

CONTAMINATED REFRIGERANT

Take 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.

• In case of repairing, recover the refrigerant using only dedicated equipment and containers. Never

recover contaminated refrigerant into the existing service equipment. Contact a local refrigerant prod-

uct retailer for available service if the facility does not have dedicated recovery equipment. This refrigerant

must be disposed of in accordance with all federal and local regulations. In addition, replacement of all

refrigerant system 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.

REFRIGERANT CONNECTION

A new type refrigerant connection has been introduced to all 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 loosen 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.

HA-6

< PRECAUTION >

PRECAUTIONS

• Use always a torque wrench and a back-up wrench when connecting tubes.

• Plug immediately 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 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 refrigeration system before charging the refrigerant.

• Replace always used O-rings.

• Apply lubricant to circle of the 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 mounted on the car when the compressor is removed.

• Follow “Maintenance of Lubricant Quantity in Compressor” exactly when replacing or repairing

compressor. Refer to

HA-21, "Description"

• Keep friction surfaces between clutch and pulley clean. Wipe it off by using a clean waste cloth

moistened with thinner if the surface is contaminated with lubricant.

• Turn the compressor shaft by hand more than five turns in both directions after compressor service

operation. This distributes equally lubricant inside the compressor. Let the engine idle and operate

the compressor for one hour after the compressor is installed.

• Apply voltage to the new one and check for normal operation after replacing the compressor magnet

clutch.

LEAK DETECTION DYE

CAUTION:

• The A/C system contains a fluorescent leak detection dye used for locating refrigerant leakages. An

ultraviolet (UV) lamp is required to illuminate the dye when inspecting for leakages.

• Wear always fluorescence enhancing UV safety goggles to protect eyes and enhance the visibility of

the fluorescent dye.

• The fluorescent dye leak detector is not a replacement for an electrical leak detector (SST: J-41995).

The fluorescent dye leak detector should be used in conjunction with an electrical leak detector

(SST: J-41995) to pin-point refrigerant leakages.

• Read and follow all manufacture’s operating instructions and precautions prior to performing the

work for the purpose of safety and customer’s satisfaction.
