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 Procedure without Cowl Top Cover

INFOID:0000000010120886

When performing the procedure after removing cowl top cover, cover

the lower end of windshield with urethane, etc to prevent damage to

windshield.

High Voltage Precautions

INFOID:0000000010120887

DANGER:

Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of

electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are

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

maintenance.

WARNING:

• 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.

• The removed service plug must always be carried in a pocket of the responsible worker or placed in

the tool box during the procedure to prevent the plug from being connected by mistake.

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

• Never allow workers other than the responsible person to touch the vehicle containing high voltage

parts. To keep others from touching the high voltage parts, these parts must be covered with an insu-

lating sheet except when using them.

CAUTION:

Never bring the vehicle into the READY status with the service plug removed unless otherwise

instructed in the Service Manual. A malfunction may occur if this is not observed.

HIGH VOLTAGE HARNESS AND EQUIPMENT IDENTIFICATION

PIIB3706J

TMS-6

< PRECAUTION >

PRECAUTIONS

All the high voltage harnesses and connectors are orange. The Li-ion battery and other high voltage devices

include an orange high voltage label. Never touch these harnesses and high voltage 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

Hybrid vehicles and electric vehicles contain parts with high voltage and intense magnetic force. Never carry

metal products and magnetic recording media (e.g. cash card, prepaid card) to repair/inspect high voltage

parts. If this is not observed, the metal products may create a risk of short circuit and the magnetic recording

media may lose their magnetic recording.

Precautions for Removing Battery Terminal

INFOID:0000000010120888

• When removing the 12V battery terminal, turn OFF the power

switch and wait at least 5 minutes.

NOTE:

ECU may be active for several minutes after the power switch is

turned OFF. If the battery terminal is removed before ECU stops,

then a DTC detection error or ECU data corruption may occur.

• Always disconnect the battery terminal within 60 minutes after

turning OFF the power switch. Even when the power switch is

OFF, the 12V battery automatic charge control may automatically

start after a lapse of 60 minutes from power switch OFF.

•  Disconnect 12V battery terminal according to the following steps.

WORK PROCEDURE

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 terminal within 60 minutes after turning the power switch OFF 

→ ON → OFF.

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.

NOTE:

Once the power switch is turned ON 

→ OFF, the 12V battery automatic charge control does not start for

approximately 1 hour.

• For vehicles with the 2-batteries, be sure to connect the main battery and the sub battery before turning ON

the power switch.

NOTE:

If the power switch is turned ON with any one of the terminals of main battery and sub battery disconnected,

then DTC may be detected.

• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:

The removal of 12V battery may cause a DTC detection error.

General Precautions

INFOID:0000000010120889

CAUTION:

If the traction motor inverter or traction motor was replaced, be sure to perform writing of the traction

motor resolver offset. Refer to 

TMS-39, "Description"

.

Take care when handling the traction motor inverter so that dust, dirt, and other substances do not enter into

the inside from the opening.
