Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001548120
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 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 SRS 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 Procedures Without Cowl Top CoverINFOID:0000000001548121
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Working with HFC-134a (R-134a)INFOID:0000000001547383
WARNING:
 CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants
are mixed compressor failure is likely to occur. Refer to XX-XX, "*****"
. To determine the purity of
HFC-134a (R-134a) in the vehicle and recovery tank, use Refrigerant Recovery/Recycling Recharging
equipment and Refrigerant Identifier.
 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 failure 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.
Remove HFC-134a (R-134a) from the A/C system using certified service equipment meeting require-
ments of SAE J2210 [HFC-134a (R-134a) recycling equipment], or J2209 [HFC-134a (R-134a) recy-
cling equipment], If accidental system discharge occurs, ventilate work area before resuming
service. Additional health and safety information may be obtained from refrigerant and oil manufac-
turers.

System DiagramINFOID:0000000001728854
System DescriptionINFOID:0000000001728855
OUTLINE
• Interior room lamps* are controlled by the interior room lamp timer control function of the BCM.
*Map lamp, interior room lamp, vanity lamps and trunk room lamp.
The timer control functions of the BCM activate based on inputs from the remote keyless entry receiver, the
key cylinder lock/unlock switch, the door switches, the key switch and key lock solenoid (without Intelligent
Key) or the key switch and ignition knob switch (with Intelligent Key).
ROOM LAMP TIMER OPERATION
When the interior room lamp switch is in the DOOR position and when all conditions below are met, the BCM
begins timer control (maximum 30 seconds) for interior room lamp ON/OFF.
 When the front door LH is unlocked [with Intelligent Key, main power window and door lock/unlock switch, or
front door lock assembly (key cylinder switch)].
 When a door opens → closes and the Intelligent Key is not inserted in the key slot.
Timer control is canceled under the following conditions.
 When the front door LH is locked [with Intelligent Key, main power window and door lock/unlock switch, or
front door lock assembly (key cylinder switch)].
 A door is opened (door switch turns ON).
 Intelligent Key is inserted into the key slot.
Interior lamp operational settings can be changed with the function setting of CONSULT-III.
INTERIOR LAMP BATTERY SAVER CONTROL
If an interior lamp is left ON and does not turn OFF even when the doors are closed, the BCM turns off power
to the interior lamps automatically to save the battery 30 minutes after the ignition switch is turned OFF.
The BCM controls power and ground to all interior lamps.
After the battery saver system turns the lamps OFF, the lamps will illuminate again when

General precautions for service operationsINFOID:0000000001726697
 When removing or disassembling any part, be careful not to damage or deform it. Protect parts which may
get in the way with cloth.
 When removing parts with a screw driver or other tool, protect parts by wrapping them with vinyl or tape.
 Keep removed parts protected with cloth.
 If an non-reuseable part is removed, replace it with a new one.
 After re-assembly has been completed, make sure each part functions correctly.
 Never work with wet hands.
 Turn the lighting switch OFF before disconnecting and connecting the connector.
 Do not use organic solvent (paint thinner or gasoline) to clean lamps or remove sealant residue.
