Precaution for Technicians Using Medical Electric
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 on board charger at normal charge operation may effect medical
electric devices, a technician using a medical electric device such as implantable cardiac pacemaker or an
implantable cardioverter defibrillator must not enter the vehicle compartment (including luggage room) 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 interior/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 implantable 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 interior/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 implantable 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 manufacturer before Intelligent Key use.
Point to Be Checked Before Starting Maintenance Work
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 Supplemental Restraint System (SRS) "AIR BAG" and
"SEAT BELT PRE-TENSIONER"
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 “SRS AIR BAG” and “SEAT BELT” of this Service Manual.
WARNING:
Always observe the following items for preventing accidental activation.
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, it is recommended that all maintenance and repair be performed by
an authorized NISSAN/INFINITI dealer.
Improper repair, 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 “SRS AIR BAG”.
Never 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 harness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC)
AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation.
When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the power switch ON,
never 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 power switch OFF, disconnect the 12V
battery or batteries, and wait at least 3 minutes before performing any service.
Precautions for Removing Battery Terminal
When removing the 12V battery terminal, turn OFF the power switch and wait at least 5 minutes.

When the brake pedal is operated, an operating sound may be heard from the electrically-driven intelligent brake unit. This
occurs when the electrically-driven intelligent brake unit is operating normally and is not a malfunction.
When the brake pedal is depressed when the EV system is not started, the brake pedal will feel heavy and the stroke will be
shorter. When the unfamiliar feeling disappears and the brake warning lamp is OFF after the brake pedal was depressed, then
this is not a malfunction. When the brake warning lamp is ON, use CONSULT and perform the “BRAKE” self diagnosis.
When there is a malfunction in the power system of the electrically-driven intelligent brake unit (no voltage is generated),
voltage is temporarily supplied to the electrically-driven intelligent brake unit from the brake power supply backup unit. At
the same time, the brake warning lamp (red) and brake system warning lamp (yellow) turn ON, and the warning buzzer
sounds.
When a malfunction occurs in the electrically-driven intelligent brake unit, the VDC function performs control (boost
operation).
When a malfunction occurs in the DC/DC-J/B and 12V battery, the braking force is determined by the force pressing on the
brake pedal (no boost operation). At the same time, the brake warning lamp (red) and the brake system warning lamp (yellow)
turns ON.
When a malfunction occurs in the electrically-driven intelligent brake and in the VDC function, the braking force is
determined by the force pressing on the brake pedal (no boost operation). At the same time, the brake warning lamp (red) and
brake system warning lamp (yellow) turn ON.
When a malfunction occurs in the electrically-driven intelligent brake, VDC function, and power system, then cooperative
regenerative brake control is not performed.
When a malfunction occurs in the brake power supply backup unit, the brake system warning lamp (yellow) turns ON.
