PRECAUTIONS
Precaution for Technicians Using Medical Electric
INFOID:0000000010120233
OPERATION PROHIBITION
WARNING:
• Parts with strong magnet is used in this vehicle.
• Technicians using a medical electric device such as pacemaker must never perform operation on the
vehicle, as magnetic field can affect the device function by approaching to such parts.
NORMAL CHARGE PRECAUTION
WARNING:
• If a technician uses a medical electric device such as an implantable cardiac pacemaker or an
implantable cardioverter defibrillator, the possible effects on the devices must be checked with the
device manufacturer before starting the charge operation.
• As radiated electromagnetic wave generated by PDM (Power Delivery Module) at normal charge
operation may affect medical electric devices, a technician using a medical electric device such as
implantable cardiac pacemaker or an implantable cardioverter defibrillator must not approach motor
room [PDM (Power Delivery Module)] at the hood-opened condition during normal charge operation.
PRECAUTION AT TELEMATICS SYSTEM OPERATION
WARNING:
• If a technician uses implantable cardiac pacemaker or implantable cardioverter defibrillator (ICD),
avoid the device implanted part from approaching within approximately 220 mm (8.66 in) from inte-
rior/exterior antenna.
• The electromagnetic wave of TCU might affect the function of the implantable cardiac pacemaker or
the implantable cardioverter defibrillator (ICD), when using the service, etc.
• If a technician uses other medical electric devices than implantable cardiac pacemaker or implant-
able cardioverter defibrillator (ICD), the electromagnetic wave of TCU might affect the function of the
device. The possible effects on the devices must be checked with the device manufacturer before
TCU use.
PRECAUTION AT INTELLIGENT KEY SYSTEM OPERATION
WARNING:
• If a technician uses implantable cardiac pacemaker or implantable cardioverter defibrillator (ICD),
avoid the device implanted part from approaching within approximately 220 mm (8.66 in) from inte-
rior/exterior antenna.
• The electromagnetic wave of Intelligent Key might affect the function of the implantable cardiac
pacemaker or the implantable cardioverter defibrillator (ICD), at door operation, at each request
switch operation, or at engine starting.
• If a technician uses other medical electric devices than implantable cardiac pacemaker or implant-
able cardioverter defibrillator (ICD), the electromagnetic wave of Intelligent Key might affect the
function of the device. The possible effects on the devices must be checked with the device manu-
facturer before Intelligent Key use.
Point to Be Checked Before Starting Maintenance Work
INFOID:0000000010120234
The high voltage system may starts automatically. It is required to check that the timer air conditioner
and timer charge (during EVSE connection) are not set before starting maintenance work.
NOTE:
If the timer air conditioner or timer charge (during EVSE connection) is set, the high voltage system starts
automatically even when the power switch is in OFF state.
Precaution for Removing 12V Battery
INFOID:0000000010120235
1. Check that EVSE is not connected.
NOTE:
If EVSE is connected, the air conditioning system may be automatically activated by the timer A/C func-
tion.

PRECAUTIONS
2. Turn the power switch OFF
→ ON → OFF. Get out of the vehicle. Close all doors (including back door).
3. Check that the charge status indicator lamp does not blink and wait for 5 minutes or more.
NOTE:
If the battery is removed within 5 minutes after the power switch is turned OFF, plural DTCs may be
detected.
4. Remove 12V battery within 1 hour after turning the power switch OFF
→ ON → OFF.
NOTE:
• The 12V battery automatic charge control may start automatically even when the power switch is in
OFF state.
• Once the power switch is turned ON
→ OFF, the 12V battery automatic charge control does not start for
approximately 1 hour.
CAUTION:
• After all doors (including back door) are closed, if a door (including back door) is opened before
battery terminals are disconnected, start over from Step 1.
• After turning the power switch OFF, if “Remote A/C” is activated by user operation, stop the air
conditioner and start over from Step 1.
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000010120236
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. 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 SR and SB section of this Service Man-
ual.
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.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) 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
battery and wait at least three minutes before performing any service.
Service
INFOID:0000000010120237
• Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
• Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least three
minutes.
For approximately three minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least three minutes
have passed.
• Diagnosis sensor unit must always be installed with their arrow marks “
⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installa-
tion and replace as required.
• The spiral cable must be aligned with the neutral position since its rotations are limited. Do not turn steering
wheel and column after removal of steering gear.
