dled incorrectly. Be sure to follow the correct work procedures when performing inspection and

maintenance.

• Be sure to remove the service plug in order to disconnect the high voltage circuits before perform-

ing inspection or maintenance of high voltage system harnesses and parts.

• To prevent the removed service plug from being connected by mistake during the procedure, always

carry it in your pocket or put it in the tool box.

• Be sure to wear insulating protective equipment before beginning work on the high voltage system.

• Clearly identify the persons responsible for high voltage work and ensure that other persons do not

touch the vehicle. When not working, cover high voltage parts with an insulating cover sheet or sim-

ilar item to prevent other persons from contacting them.

CAUTION:

There is the possibility of a malfunction occurring if the vehicle is changed to READY status while the

service plug is removed. Therefore do not change the vehicle to READY status unless instructed to do

so in the Service Manual.

HIGH VOLTAGE HARNESS AND EQUIPMENT IDENTIFICATION

The colors of the high voltage harnesses and connectors are all orange. Orange "High Voltage" labels are

applied to the Li-ion battery and other high voltage devices. Do not carelessly touch these harnesses and

parts.

HANDLING OF HIGH VOLTAGE HARNESS AND TERMINALS

Immediately insulate disconnected high voltage connectors and terminals with insulating tape.

REGULATIONS ON WORKERS WITH MEDICAL ELECTRONICS

WARNING:

The vehicle contains parts that contain powerful magnets. If a person who is wearing a heart pace-

maker or other medical device is close to these parts, the medical device may be affected by the mag-

nets. Such persons must not perform work on the vehicle.

PROHIBITED ITEMS TO CARRY DURING THE WORK

Because this vehicle uses components that contain high voltage and powerful magnetism, due not carry any

metal products which may cause short circuits, or any magnetic media (cash cards, prepaid cards, etc.) which

may be damaged on your person when working.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000010119354

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

JSAIA1600GB

< PRECAUTION >

PRECAUTIONS

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.

Precaution for Removing 12V Battery

INFOID:0000000010119355

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.

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
