Precaution for Technicians Using Medical Electric

INFOID:0000000010119447

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:0000000010119448

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"

INFOID:0000000010119449

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.

Precautions for Suspension

INFOID:0000000010119450

• When installing rubber bushings, the final tightening must be carried out under unladen conditions with tires

on ground. Spilled oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.

- "Unladen conditions" means that fluids and lubricants are full. Tire repair kit and mats are in designated posi-

tions.

• After servicing suspension parts, be sure to check wheel alignment.

• Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-oiled,

tighten as they are. 

• The tightening surface must be kept free from oil/grease.

• When jacking up the vehicle with a floor jack, never hang the jack on the suspension beam.
