Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003894443
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 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”.
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.

NOTE:
Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-
tion, 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-III 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.
This vehicle is equipped with a push-button ignition switch and a 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 procedure
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 push-button 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.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)

Precautions For Xenon Headlamp ServiceINFOID:0000000003894448
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:0000000003894449
CAUTION:
CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. These refrigerants
must never be mixed, even in the smallest amounts. Compressor malfunction is likely occur if the
refrigerants are mixed.
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 (NISSAN A/C System Oil Type S) to come in contact with styrene foam parts.
Damage may result.
General Refrigerant PrecautionINFOID:0000000003894450
WARNING:
Never breath A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant.

VTL-66
< PRECAUTION >[WITH 7 INCH DISPLAY]
PRECAUTIONS
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 equipment to capture 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 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.
Refrigerant ConnectionINFOID:0000000003894451
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 a wrong O-ring is
installed.

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 causes 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.
