SYSTEM DESCRIPTION
• The engine start function of Intelligent Key system is a system that makes it possible to start and stop the N
engine without removing the key. It verifies an electronic ID using two-way communication when pressing
the push-button ignition switch while carrying the Intelligent Key, which operates based on the results of
electronic ID verification of Intelligent Key using two-way communication between the Intelligent Key and the O
vehicle.
NOTE:
The driver should carry the Intelligent Key at all times.
• Intelligent Key has 2 IDs [Intelligent Key and IVIS (NATS)]. It can perform the door lock/unlock operation and P
the push-button ignition switch operation when the registered Intelligent Key is carried.
• When the Intelligent Key battery is discharged, it can be used as emergency back-up by inserting the Intelli-
gent Key to the key slot. At that time, perform the IVIS (NATS) ID verification. If it is used when the Intelligent
Key is carried, perform the Intelligent Key ID verification.
• If the ID is successfully verified, and when push-button ignition switch is pressed, steering lock is released
and the engine can be started.

• Up to 4 Intelligent Keys can be registered (Including the standard Intelligent Key) upon request from the cus-
tomer.
NOTE:
Refer to DLK-15, "INTELLIGENT KEY SYSTEM : System Description" for any functions other than engine
start function of Intelligent Key system.
PRECAUTIONS FOR INTELLIGENT KEY SYSTEM
In the Intelligent Key system, the transponder [the chip for IVIS (NATS) ID verification] is integrated
into the Intelligent Key. (For the conventional models, it is integrated into the mechanical key.) There-
fore, the mechanical key cannot perform ID verification, and thus it cannot start the engine. Instead,
IVIS (NATS) ID verification can be performed by inserting the Intelligent Key to the key slot, and then it
can start the engine.
OPERATION WHEN INTELLIGENT KEY IS CARRIED
1. When the push-button ignition switch is pressed, the BCM activates the inside key antenna and transmits
the request signal to the Intelligent Key.
2. The Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to the BCM via
the remote keyless entry receiver.
3. The Intelligent Key receives the Intelligent Key ID signal and verifies it with the registered ID.
4. BCM transmits the steering lock unlock signal to steering lock unit and IPDM E/R if the verification results
are OK.
5. IPDM E/R turns the steering lock relay ON and supplies power supply to the steering lock unit.
6. The steering lock releases.
7. BCM transmits the power supply stop signal to IPDM E/R when detecting that the steering lock is in the
unlock condition.
8. IPDM E/R turns the steering lock relay OFF and stops power supply to the steering lock unit.
9. BCM turns ACC relay ON and transmits the ignition power supply ON signal to IPDM E/R.
10. IPDM E/R turns the ignition relay ON and starts the ignition power supply.
11. BCM detects that the selector lever position and brake pedal operating condition (A/T models) or shift
lever position and clutch pedal operation condition (M/T models).
12. BCM transmits the starter request signal via CAN communication to IPDM E/R and turns the starter relay
in IPDM E/R ON if BCM judges that the engine start condition is satisfied.
13. IPDM E/R turns the starter control relay ON when receiving the starter request signal.
14. Power supply is supplied through the starter relay and the starter control relay to operate the starter motor
and start cranking.
CAUTION:
If a malfunction is detected in the Intelligent Key system, the “KEY” warning lamp in the combina-
tion meter illuminates. At that time, the engine cannot be started.
15. When BCM receives feedback signal from ECM indicating that the engine is started, the BCM transmits a
stop signal to IPDM E/R and stops cranking by turning OFF the starter motor relay. (If engine start is
unsuccessful, cranking stops automatically within 5 seconds.)
CAUTION:
When the Intelligent Key is carried outside of the vehicle (inside key antenna detection area) while
the power supply is in the ACC or ON position, even if the engine start condition* is satisfied, the
engine cannot be started.
*: For the engine start condition, refer to “PUSH-BUTTON IGNITION SWITCH OPERATION PROCEDURE”.
OPERATION RANGE
Engine can be started when Intelligent Key is inside the vehicle. However, sometimes engine may not start
when Intelligent Key is on instrument panel or in glove box.
OPERATION WHEN KEY SLOT IS USED
When the Intelligent Key battery is discharged, it performs IVIS (NATS) ID verification between the integrated
transponder and BCM by inserting the Intelligent Key into the key slot, and then the engine can be started.
For details relating to starting the engine using key slot, refer to SEC-15, "System Description".

SYSTEM DESCRIPTION
• The IVIS (NATS) is an anti-theft system that registers an Intelligent Key ID to the vehicle and prevents the
engine from being started by an unregistered Intelligent Key. It has higher protection against auto theft
involving the duplication of mechanical keys. N
• It performs ID verification when starting the engine in the same way as the Intelligent Key system. But, it per-
forms the IVIS (NATS) ID verification when inserting the Intelligent Key and performs the Intelligent Key ID
verification when carrying the Intelligent Key. O
• The mechanical key integrated in the Intelligent Key cannot start the engine. When the Intelligent Key bat-
tery is discharged, the IVIS (NATS) ID verification memorized to the transponder integrated with Intelligent
Key is performed by inserting the Intelligent Key into the key slot. If the verification results are OK, the
engine start operation can be performed by the push-button ignition switch operation. P
• Locate the security indicator lamp and apply the anti-theft system equipment sticker that warns that the IVIS
(NATS) is onboard the model.
• Security indicator lamp always blinks when the power supply position is in the except ON position.
• Up to 4 Intelligent Keys can be registered (including the standard ignition key) upon request from the owner.
• Specified registration is required when replacing ECM, BCM, or Intelligent Key. For the registrations proce-
dures for IVIS (NATS) and Intelligent Key when installing the BCM, refer to CONSULT-III Operation Manual
NATS-IVIS/NVIS.

• Possible symptom of IVIS (NATS) malfunction is “Engine cannot start”. The engine can be started with the
Intelligent Key system and IVIS (NATS). Identify the possible causes according to “Work Flow”. Refer to
SEC-5, "Work Flow".
• If ECM other than genuine part is installed, the engine cannot be started. For ECM replacement procedure,
refer to EC-16, "ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT (ECM) : Special Repair
Requirement".
PRECAUTIONS FOR KEY REGISTRATION
• The key registration is a procedure that erases the current IVIS (NATS) ID once, and then reregisters a new
ID operation. Therefore a registered Intelligent Key is necessary for this procedure. Before starting the regis-
tration operation collect all registered Intelligent Keys from the customer.
• When registering the Intelligent Key, perform only one procedure to simultaneously register both ID (IVIS
“NATS” ID and Intelligent Key ID).
The IVIS (NATS) ID registration is the procedure that registers the ID stored into the transponder (integrated
in Intelligent Key) to BCM.
The Intelligent key ID registration is the procedure that registers the ID to BCM.
• When performing the Intelligent Key system registration only, the engine cannot be started by inserting the
key into the key slot. When performing the IVIS (NATS) registration only, the engine cannot be started by the
operation when carrying the key. The registrations of both systems should be performed.
SECURITY INDICATOR LAMP
• Warns that the vehicle is equipped with IVIS (NATS).
• Security indicator lamp always blinks when the ignition switch is in the except ON position.
NOTE:
Because security indicator lamp is highly efficient, the battery is barely affected.

SETTING THE VEHICLE SECURITY SYSTEM P

Initial Condition
Ignition switch is in OFF position.
Disarmed Phase
• When any door or trunk lid is open, the vehicle security system is set in the disarmed phase on the assump-
tion that the owner is inside or near the vehicle.

• When the vehicle security system is in the disarmed phase, the security indicator lamp blinks every 2.4 sec-
onds.
Pre-armed Phase and Armed Phase
When the following operation 1 or 2 is performed, the vehicle security system turns into the “pre-armed”
phase. (Security indicator lamp illuminates.)
1. BCM receives LOCK signal from door lock and unlock switch, door key cylinder switch door request
switch or Intelligent Key, after all doors are closed.
2. All doors are closed after all doors are locked by mechanical key or door lock and unlock switch.
CANCELING THE ARMED PHASE VEHICLE SECURITY SYSTEM
When one of the following operations is performed, the armed phase is canceled.
1. Unlock all doors with the door lock and unlock switch, door key cylinder switch, door request switch or
Intelligent Key.
2. Turn ignition switch “ON” or “ACC” position.
CANCELING THE ALARM OPERATION OF THE VEHICLE SECURITY SYSTEM
When on of the following operations is performed, the alarm operation is canceled.
1. Unlock all doors with the door request switch or Intelligent Key.
2. Turn ignition switch “ON” or “ACC” position.
ACTIVATING THE ALARM OPERATION OF THE VEHICLE SECURITY SYSTEM
Check that the system is in the armed phase. (Security indicator lamp blinks every 2.4 seconds.)
When the following operation 1 or 2 is performed, the system sounds the horns and blinks the headlamps for
about 50 seconds.
1. Trunk lid, any door or hood is opened during armed phase.
2. Disconnecting and connecting the battery connector before canceling armed phase.
PANIC ALARM OPERATION
When BCM receives panic alarm signal from Intelligent Key, ground is supplied intermittently to both head-
lamp relay and horn relay.
When headlamp relay and horn relay are energized, then power is supplied to headlamps (HI) and horns
(high, low and vehicle security horn).
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds or when BCM receives any signal from Intelligent Key or
door request switch.

PRECAUTIONS
< PRECAUTION >
PRECAUTION A
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT B
PRE-TENSIONER" INFOID:0000000005151394
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along C
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. 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. D
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING: E
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
F
• 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 AIR BAG”.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this G
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS H
WARNING:
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) I
with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly
causing serious injury.
• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the J
battery, and wait at least 3 minutes before performing any service.
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000005151395 SEC
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. L
• 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. M
If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
For vehicle with 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 operation pro- N
cedure below before starting the repair operation.
OPERATION PROCEDURE
O
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. P
(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.

PRECAUTIONS
< PRECAUTION >
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.)
6. Perform self-diagnosis check of all control units using CONSULT-III.
Precautions For Xenon Headlamp Service INFOID:0000000005151396
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.).
