PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612929
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 severi ty of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution Necessary for Steering Wh eel Rotation After Battery Disconnect
INFOID:0000000001612931
NOTE:
 This Procedure is applied only to models with Intell igent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
 Remove and install all control units after disconnecti ng both battery cables with the ignition knob in the
″ LOCK ″ position.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, 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. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-III.

AIR CONDITIONER CONTROL
 When pressing AUTO switch, air inlet, air outlet, fan speed, and discharge air temperature are automatically
controlled.
TEMPERATURE CONTROL SWITCH (POTENTIO TEMPERATURE CONTROL) (DRIVER SIDE)
The set temperature is increased or decreased with this switch.
TEMPERATURE CONTROL SWITCH (POTENTIO TEMPERATURE CONTROL) (PASSENGER
SIDE)
 The set temperature is increased or decreased with this switch.
 When the temperature switch is pressed, the DUA L switch indicator will automatically illuminate.
INTAKE SWITCH
 When intake switch is ON, REC LED turns ON, and air inlet is fixed to REC.
 When press intake switch again, FRE LED turns ON, and air inlet is fixed to FRE.
 When intake switch is pressed for approximately 1. 5 seconds or longer, FRE and REC LEDs blink twice.
Then, automatic control mode is entered. Inlet status is displayed by LED even during automatic controlled.
 When FRE LED is turned ON, shifting mode position to D/ F or DEF, or when compressor is turned from ON
to OFF, intake switch is automatically turned OFF (fixed to FRE mode). REC mode can be re-entered by
pressing intake switch again, and then compressor is turned ON. (Except D/F or DEF position)
DEFROSTER (DEF) SWITCH
Mode doors are set to the defrost position with this switch . Also, intake doors are set to the outside air position,
and compressor turns ON.
REAR WINDOW DEFOGGER SWITCH
When illumination is ON, rear window is defogged.
OFF SWITCH
Compressor and blower are OFF, the intake door s and the mode doors are automatically controlled.
A/C SWITCH
Compressor is ON or OFF with this switch.
(Pressing the A/C switch when the A/C switch is ON will turn OFF the A/C switch and compressor.)
MODE SWITCH
The air discharge outlets is controlled with this switch.
FAN SWITCH
The blower speed is manually controlled with this swit ch. Seven speeds are available for manual control (as
shown on the display screen).
DUAL SWITCH
 When the DUAL switch indicator is illuminated, the driver side and passenger side temperature can each be set independently.
 When the DUAL switch indicator is not illuminated, t he driver side setting temperature is applied to both
sides.
Fail-Safe FunctionINFOID:0000000001328171
If a communication error exists between the unified meter and A/C amp., and the A/C and AV switch for 30
seconds or longer, air conditioner is controlled under following conditions:
Compressor : ON
Air outlet : AUTO
Air inlet : FRE (Fresh)
Blower fan speed : AUTO
Set temperature : Setting befo re communication error occurs

TROUBLE DIAGNOSIS
Shifting from STEP-5 to AUXILIARY MECHANISM is accomplished by means of pressing (fan) UP switch.
FUNCTION CONFIRMATION PROCEDURE
1.SET IN SELF-DIAGNOSIS MODE
1. Turn ignition switch ON.
2. Set in self-diagnosis mode as follows. Within 10 seconds after starting engine (ignition switch is turned ON.), press OFF switch for at least 5 seconds.
NOTE:
 If battery voltage drops below 12 V during diagnosis STEP-3, door motor speed becomes slower and as a
result, the system may generate an error even when operation is normal. To avoid this, start engine before
performing this diagnosis.
 Former STEP-1 (LEDs and display screen are checked) does not exist in this self-diagnosis function.
