The
high-voltage system can be shut down with any 1 of the following procedures:• Turn OFF the power switch and disconnect the 12-volt battery. Refer to Primary Procedure
(FRG–21) .
•

Disconnect the underhood fuse panel terminal connector for the high-voltage control system and
disconnect the 12-volt battery. Refer to Alternate Procedure 1 (Disconnect Underhood Fuse
Panel)

(FRG–24) .
•

Remove the service plug and disconnect the 12-volt battery. Refer to Alternate Procedure 2

Service Plug) (FRG–27) .
Primary

Procedure
NOTE:
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust
the steering column, adjust the seats, unlock the doors, etc. Once 12-volt battery is
disconnected, power controls will not operate.
1. If possible, check the READY indicator status in the instrument cluster. If it is on, the high-
voltage

system is active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch once to turn OFF the high- voltage system. Verify that the READY indicator is off
and then continue to the next steps to open the trunk
for 12-volt battery negative cable access.
If the READY indicator does not turn off, refer to
Alternate Procedure 1 (Disconnect Underhood Fuse
Panel)
(FRG–24)
4. If possible, keep the Infiniti Intelligent Key at least 5
meters (16 feet) away from the vehicle (except to

Alternate Procedure 1 (Disconnect Underhood Fuse Panel)
NO
TE:
Before disconnecting the underhood fuse panel and the negative (-) battery cable, if

disconnect terminal (black) connector (A) .
NOTE: : Arrow in illustration depicts vehicle front
direction.
6.

If you cannot identify the connector, disconnect all
connectors on the underhood fuse panel. To avoid unintended reinstallation and risk of electrical shock and severe personal injury or
death,

the rescuer should cover the fuse box and connectors with insulated tape or remove
the fuse panel and carry on his/her person.

Alternate Procedure 2 (Remove Service Plug)
DANGER
• Do not remove the service plug without always wearing appropriate Personal
Protective Equipment (PPE) to help protect the responder from serious injury or death
by electrical shock.
• Immediately cover the service plug socket with insulated tape. The high-voltage
battery
retains high-voltage power even when the service plug is removed. To avoid
electric shock, NEVER touch the terminals inside the socket. To avoid unintended reinstallation and risk of electrical shock and severe personal injury
or

death, the rescuer should carry the service plug on his/her person while work is in
progress.
NOTE: Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust
the steering column, adjust the seats, unlock the doors, etc. Once 12-volt battery is
disconnected, power controls will not operate.
1. If possible, check the READY indicator status in the instrument cluster. If it is on, the high-
voltage

system is active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch once to turn OFF the high- voltage system. Then verify whether the READY
indicator is off.

3-3.2 Water Submersion DANGER
Damage level of submerged vehicle may not be apparent. Handling a submerged
vehicle
without appropriate Personal Protective Equipment (PPE) will result in serious
injury or death from electrical shock. • The ignition switch of the submerged vehicle must be turned OFF first, if possible.
Then
the vehicle must be completely out of the water and drained to avoid electrical
shock.
• Always wear appropriate Personal Protective Equipment (PPE) and remove/drain
water
before removing the service plug when working on a vehicle after a fire or
submersion to avoid electrical shock.
• If the vehicle is in the water, to avoid electrical shock NEVER touch the high-voltage
components,
harnesses or service plug. PPE must always be worn when touching or
working on high-voltage components. A
