PRECAUTIONS
Precaution for Procedure without Cowl Top Cover
INFOID:0000000003846397
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions For Xenon Headlamp ServiceINFOID:0000000003846398
WARNING:
Comply with the following warnings to prevent any serious accident.
 Disconnect the battery cable (negative terminal) or the power supply fuse before installing, remov-
ing, or touching the xenon headlamp (bulb included). The xenon headlamp contains high-voltage
generated parts.
 Never work with wet hands.
 Check the xenon headlamp ON-OFF status after assembling it to the vehicle. Never turn the xenon
headlamp ON in other conditions. Connect the power supply to the vehicle-side connector.
(Turning it ON outside the lamp case may cause fire or visual impairments.)
 Never touch the bulb glass immediately after turning it OFF. It is extremely hot.
CAUTION:
Comply with the following cautions to prevent any error and malfunction.
 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:0000000003846399
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) 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. Immediately reseal containers of lubricant.
Lubricant becomes moisture saturated 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.

< SYMPTOM DIAGNOSIS >[WITH 7 INCH DISPLAY]
NOISE
NOISE
DescriptionINFOID:0000000003884805
Symptom
Noise
 Noise is heard when the A/C system operates.
Inspection procedureINFOID:0000000003884806
1.CHECK OPERATION
1. Operate the A/C system and check the operation. Refer to HAC-108, "
WITHOUT INTELLIGENT AIR
CONDITIONER SYSTEM : Description & Inspection" (WITHOUT INTELLIGENT AIR CONDITIONER
SYSTEM) or HAC-112, "
WITH INTELLIGENT AIR CONDITIONER SYSTEM : Description & Inspection"
(WITH INTELLIGENT AIR CONDITIONER SYSTEM).
2. Check the parts where noise is occurring.
Can the parts where noise is occurring be checked?
YES-1 >> Noise from blower motor: GO TO 2.
YES-2 >> Noise from compressor: GO TO 3.
YES-3 >> Noise from expansion valve: GO TO 4.
YES-4 >> Noise from A/C piping (pipe, flexible hose): GO TO 6.
YES-5 >> Noise from drive belt: GO TO 7.
NO >> END.
2.CHECK BLOWER MOTOR
1. Remove blower motor.
2. Remove foreign materials that are in the blower unit.
3. Check the noise from blower motor again.
Is the inspection result normal?
YES >> END.
NO >> Replace blower motor.
3.CHECK COMPRESSOR
Perform trouble diagnosis for the compressor and check the compressor. Refer to HA-11, "
Symptom Table".
Is the inspection result normal?
YES >> END.
NO >> Refill the refrigerant or replace the compressor according to the inspection results.
4.CHECK WITH GAUGE PRESSURE
Perform the diagnosis with the gauge pressure. Refer to HA-8, "
Trouble Diagnosis For Unusual Pressure".
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair or replace parts according to the inspection results.
5.CHECK EXPANSION VALVE
1. Correct the refrigerant with recovery/recycling recharging equipment.
2. Recharge with the proper amount of the collected refrigerant after recycling or new refrigerant.
3. Check for the noise from expansion valve again.
Are the malfunction solved?
YES >> END.
NO >> Replace expansion valve.
6.CHECK A/C PIPING (PIPE, FLEXIBLE HOSE)
1. Check the A/C piping (pipes, flexible hoses) (for deformation and damage, etc.).
2. Check the installation condition of clips and brackets, etc, of the A/C piping (pipes, flexible hoses).
Is the inspection result normal?
YES >> Fix the line with rubber or come vibration absorbing material.
