• 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 as it is when mounted on the vehicle when the compressor is removed. Fail- ure to do so will cause oil 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 stag e of the operation when installing an air conditioner in the vehicle.
Do not remove the seal caps of pipes and other comp onents until just before required for connec-
tion.
• 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 moisture thoroughly from the refriger ation system before charging the refrigerant.
• Do not reuse O-rings.
• Apply oil to circle of the O-rings shown in illust ration when connecting tube. Be careful not to apply
oil 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 leak test and make sure that there are no leaks from connections after connecting line. Dis-
connect that line and replace the O-ring when the refrigerant leaking point is found. Then tighten
connections of seal seat to the specified torque.
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 refri gerant could damage service equipment and refrigerant sup-
ply.
• Suggest the customer return the vehicle to the locati on of previous service where the contamination may
have occurred.
• In case of repairing, recover the refrigerant using only dedicated equipment and containers. Do not
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.

ComponentFunction
1. Compressor Intakes, compresses, discharges and circulates refrigerant.
2. Condenser Cools the high-temperature high-pressure refrigerant discharged from the compressor to
change it into a liquid.
3. Liquid tank Filters and stores a reserve of liquid refrigerant.
4. Pressure sensor Senses refrigerant pressure for proper A/C cycle operation.
5. Evaporator Evaporates refrigerant which removes heat from the air lowering its temperature.
6. Expansion valve Transforms high-pressure liquid refrigerant to low-pressure liquid refrigerant.

< SYMPTOM DIAGNOSIS >
REFRIGERATION SYSTEM SYMPTOMS
Both high and low-pressure sides
are too low.• The area around evapora-
tor outlet does not become
cold.
• The area around evapora- tor inlet becomes frosted. Clogged expansion valve.
• Breakage of temperature
sensor.
• Clogging by foreign material. Eliminate foreign material from
expansion valve, or replace it.
• There is a temperature dif- ference between the areas
around outlet and inlet
pipes of liquid tank.
• Liquid tank becomes frost- ed. Malfunction inside liquid tank
(clogged strainer).
Replace condenser (includes
liquid tank). Refer to HA-31, "CONDENSER : Removal and
Installation".
Evaporator becomes frosted. Clogged or crushed low-pres-
sure pipe.
Repair or replace malfunction-
ing parts.
Malfunctioning thermo amp. Check thermo amp. system.
Refer to HAC-32, "
Diagnosis
Procedure".
There is a small temperature
difference between the high
and low pressure pipes. • Low refrigerant charge.
• Leak or leaks in A/C system. • Check for leaks. Refer to
HA-
18, "Leak Test".
• Recover refrigerant, evacu- ate system, and recharge
with the specified amount of
refrigerant. Refer to HA-20,
"Recycle Refrigerant".
Low-pressure side sometimes be-
comes negative. • Sometimes the area
around evaporator outlet
does not become cold.
• Sometimes the area around evaporator inlet is
frosted. • Icing caused by moisture
mixed with refrigerant.
• Deteriorated dryer material in liquid tank. Recover refrigerant then re-
place condenser (includes liq-
uid tank). Refer to HA-31,
"CONDENSER : Removal and
Installation". Evacuate system
and recharge with the specified
amount of refrigerant. Refer to
HA-20, "
Charge Refrigerant".

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012431935
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 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 SR and SB section 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 which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/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 SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified 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 Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c 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 three minutes before performing any service.
