Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000010451951
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. 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, 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 “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, and wait at least 3 minutes before performing any service.
Precautions Necessary for Steering Wheel Rotation After Battery Disconnection
INFOID:0000000010451952
CAUTION:
Comply with the following cautions to prevent any error and malfunction.
• Before removing and installing any control units, first turn the ignition switch to the LOCK position,
then disconnect both battery cables.
• After finishing work, confirm that all control unit connectors are connected properly, then re-connect
both battery cables.
• Always use CONSULT to perform self-diagnosis as a part of each function inspection after finishing
work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and
cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.
OPERATION PROCEDURE
1.
Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2.
Turn the ignition switch to ACC position.
(At this time, the steering lock will be released.)
3.
Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4.
Perform the necessary repair operation.

PRECAUTIONS
5.
When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the ignition switch from ACC position to ON position, then to LOCK position. (The steering wheel will lock
when the ignition switch is turned to LOCK position.)
6.
Perform self-diagnosis check of all control units using CONSULT.
Precaution for Procedure without Cowl Top Cover
INFOID:0000000010451953
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.
Precautions for Removing Battery Terminal
INFOID:0000000010451954
When disconnecting the battery terminal, pay attention to the following.
• Always use a 12V battery as power source.
• Never disconnect battery terminal while engine is running.
• When removing the 12V battery terminal, turn OFF the ignition
switch and wait at least 30 seconds.
• For vehicles with the engine listed below, remove the battery termi-
nal after a lapse of the specified time:
NOTE:
ECU may be active for several tens of seconds after the ignition switch is turned OFF. If the battery terminal
is removed before ECU stops, then a DTC detection error or ECU data corruption may occur.
• After high-load driving, if the vehicle is equipped with the V9X engine, turn the ignition switch OFF and wait
for at least 15 minutes to remove the battery terminal.
NOTE:
• Turbocharger cooling pump may operate in a few minutes after the ignition switch is turned OFF.
• Example of high-load driving
- Driving for 30 minutes or more at 140 km/h (86 MPH) or more.
- 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.

ing requirements of SAE J-2843 [HFO-1234yf (R-1234yf) Recovery/Recycling/Recharging Equipment
for Flammable Refrigerants for Mobile Air Conditioning Systems]. Ventilate work area before resum-
ing 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.
• 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 HFO-1234yf (R-1234yf) service equipment and/or vehicle air con-
ditioning systems with compressed air during repair. Some mixtures of air and HFO-1234yf (R-
1234yf) 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
refrigerant manufacturers.
WORKING WITH HFO-1234yf (R-1234yf)
CAUTION:
• CFC-12 (R-12) or HFC-134a (R-134a) refrigerant and HFO-1234yf (R-1234yf) refrigerant are not com-
patible. Compressor malfunction is likely to occur if the refrigerants are mixed, refer to “CONTAMI-
NATED REFRIGERANT” below. To determine the purity of HFO-1234yf (R-1234yf) in the vehicle and
recovery tank, use Refrigerant recovery/recycling recharging equipment and Refrigerant Identifier.
• Use only specified lubricant for the HFO-1234yf (R-1234yf) A/C system and HFO-1234yf (R-1234yf)
components. Compressor malfunction is likely to occur if lubricant other than that specified is used.
• The specified HFO-1234yf (R-1234yf) lubricant rapidly absorbs moisture from the atmosphere. The
following 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 (ND-OIL 12) to come in contact with styrene foam parts. Damage may result.
CONTAMINATED REFRIGERANT
Take appropriate steps shown below if a refrigerant other than pure HFO-1234yf (R-1234yf) is identi-
fied 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
![](/vehicles/gon/lolees/nshe/feny.png)
HA-10
< PRECAUTION >
[TYPE 1]
PRECAUTIONS
• Refrigerant pressure sensor to high-pressure pipe1
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.
• 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
• 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.

RECOVERY/RECYCLING RECHARGING EQUIPMENT
Be certain to follow the manufacturer’s 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’s instructions for tester operation and tester maintenance.
VACUUM PUMP
The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFO-1234yf (R-1234yf) 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 hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as per the following.
• 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 no vacuum condition. Such valves may restrict the pump’s
ability to pull a deep vacuum and are not recommended.
MANIFOLD GAUGE SET
Be certain that the gauge face indicates HFO-1234yf or R-1234yf. Be sure the gauge set has 1/2
″
-16 ACME
threaded connections for service hoses. Confirm the set has been used only with refrigerant HFO-1234yf (R-
1234yf) and specified lubricants.
SERVICE HOSES
Be certain that the service hoses display the markings described. All hoses must equip positive shut-off
devices (either manual or automatic) near the end of the hoses opposite to the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFO-1234yf (R-1234yf) service couplers
to the CFC-12 (R-12) and HFC-134a (R-134a) A/C system. The
HFO-1234yf (R-1234yf) couplers do not properly connect to the
CFC-12 (R-12) and HFC-134a (R-134a) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFO-1234yf (R-1234yf) and specified lubricants have been used with the
scale. The hose fitting must be 1/2
″
-16 ACME if the scale controls refrigerant flow electronically.
