INTELLIGENT KEY OPERATION
INTELLIGENT KEY : System DescriptionINFOID:0000000001396467
INTELLIGENT KEY OPERATION
The Intelligent Key has the same functions as the remote keyless entry system. In addition to other safety fea-
tures, it can be used to lock and unlock all doors including the back door (hatchback) or the trunk (sedan).
This function can be set to OFF with CONSULT-III. For the setting information, refer to DLK-53, "
CONSULT-III
Function (INTELLIGENT KEY)".
OPERATION CONDITION
OPERATION AREA
To ensure that the Intelligent Key works effectively, use within a 100 cm range of each door, however the oper-
able range may differ according to surroundings.
DOOR LOCK AND UNLOCK CONTROL
When door lock and unlock button of the Intelligent Key are pressed, lock signal or unlock signal is transmitted
from Intelligent Key to Intelligent Key unit.
When Intelligent Key unit receives the door lock and unlock signal, it operates door lock actuator.
Item Function
BCM Controls the door lock function.
Door switch Detects door state (open or close).
Door lock and unlock switchTransmits door lock/unlock signal to BCM. Door lock/unlock switch indicator is built-in door
lock and unlock switch.
Door lock actuator Receives door lock/unlock signal from BCM and locks/unlocks each door.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001396449
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 SR and SB section 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 SR section.
 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.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001396428
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Working with HFC-134a (R-134a)INFOID:0000000001396429
WARNING:
 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. If the refrigerants are mixed a compressor mal-
function is likely to occur.
 Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If
oil other than that specified is used, compressor malfunction is likely to occur.
 The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following
handling precautions must be observed:
- When removing refrigerant components from a vehicle, immediately cap (seal) the component to
minimize the entry of moisture from the atmosphere.
- When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just
before connecting the components. Connect all refrigerant loop components as quickly as possible
to minimize the entry of moisture into system.
- Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without
proper sealing, oil will become moisture saturated and should not be used.
- Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If acci-
dental system discharge occurs, ventilate work area before resuming service. Additional health and
safety information may be obtained from refrigerant and oil manufacturers.
- Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.

PRECAUTIONS
General Refrigerant Precaution
INFOID:0000000001396430
WARNING:
 Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If acci-
dental system discharge occurs, ventilate work area before resuming service. Additional health and
safety information may be obtained from refrigerant and oil manufacturers.
 Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
 Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air
conditioning system.
 Do not store or heat refrigerant containers above 52°C (126° F).
 Do not heat a refrigerant container with an open flame; if container warming is required, place the
bottom of the container in a warm pail of water.
 Do not intentionally drop, puncture, or incinerate refrigerant containers.
 Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
 Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent suf-
focation.
 Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condition-
ing 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 refrigerant manu-
facturers.
Oil PrecautionINFOID:0000000001396431
 Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If oil
other than that specified is used, compressor malfunction is likely to occur.
 The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following handling
precautions must be observed:
- When removing refrigerant components from a vehicle, immediately cap (seal) the component to minimize
the entry of moisture from the atmosphere.
- When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just before con-
necting the components. Connect all refrigerant loop components as quickly as possible to minimize the
entry of moisture into system.
- Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without proper seal-
ing, oil will become moisture saturated and should not be used.
 Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If accidental
system discharge occurs, ventilate work area before resuming service. Additional health and safety informa-
tion may be obtained from refrigerant and oil manufacturers.
 Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.
Precaution for Refrigerant ConnectionINFOID:0000000001396432
