• The vehicle contains parts that contain powerful magnets. If a person who is wearing
a
pacemaker or other medical device is close to these parts, the medical device may be
affected by the magnets. Such persons must not perform work on the vehicle.
• Be sure to verify that the READY indicator is off (if possible) , and the high-voltage
system
is stopped.
• After the high-voltage system is shut down, please wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor. While waiting, do not operate any
vehicle functions.
• After shutting down the high-voltage system and removing the 12-volt battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though
the 12-volt battery negative (-) is disconnected, the Supplemental Restraint System (SRS)
air bag maintains voltage at least three (3) minutes. During this time, there is a possibility
of sudden SRS air bag inflation due to harness short circuit or damage and it may cause
serious injuries.
• The 12V system will remain active even after the 12-volt battery negative (-) terminal is removed while the high-voltage system is active. This is because the charging system
will not shut down and power will be supplied to the 12V system and high-voltage system
continuously.
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, adjust the steering
column, adjust the seats, unlock the doors, open the trunk, etc. as required. Once the 12-volt battery is
disconnected, power controls will not operate.
Powering Down the High-voltage System
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
(DG–21) .
•
Remove the fuse for the high-voltage control system and disconnect the 12-volt battery. Refer to
Alternate Procedure 1 (Disconnect Underhood Fuse Panel) (DG–23).
•
Remove the service plug and disconnect the 12-volt battery. Refer to Alternate Procedure 2
(Remove
Service Plug) (DG–26) .

Primary Procedure
NO
TE:
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)
(DG–23)
4. If possible, keep the Infiniti Intelligent Key at least 5
meters (16 feet) away from the vehicle (except to
open the trunk as noted below) . AAYIA0191ZZ

NOTE:
If
the electrical release does not work, the trunk will have to be forced open.
6. Open the 12-volt battery service access cover.
7. Disconnect negative (-) battery cable and cover it withinsulated tape.
8. Wait approximately ten (10) minutes for complete discharge of the high-voltage capacitor
after the battery cable has been disconnected.
9. Perform the dismantling operation. Refer to 6. Dismantling Information (DG–40).
Alternate
Procedure 1 (Disconnect Underhood Fuse Panel)
NOTE:
Before disconnecting the underhood fuse panel and the negative (-) battery cable, if
necessary, lower the windows, adjust the steering column, adjust the seats, unlock the
doors, etc. Once the underhood fuse panel and negative (-) battery cable are disconnected,
power controls will not operate. 1. Pull release handle (1) and pull up release lever (2) to open the hood. AAYIA0195ZZ
