Powering Down the High-Voltage System
The
high-voltage system can be shut down with any 1 of the following procedures:• Turn OFF the ignition switch and disconnect the 12-volt battery. Refer to Primary Procedure (DG–21) .
•
Remove the underhood fuse for the high-voltage control system and disconnect the 12-volt battery.
Refer to Alternate Procedure 1 (Remove Fuses) (DG–23).
•
Remove the service plug and disconnect the 12-volt battery.
Refer to Alternate Procedure 2 (Remove Service Plug) (DG–25).
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 hood for
12-volt battery negative cable access.
If the READY indicator does not turn off, refer to
Alternate Procedure 1 (Remove Fuses) (DG–23).
4.
If possible, keep the Infiniti Intelligent Key at least 5
meters (16 feet) away from the vehicle. AAYIA0191ZZ

NO
TE:
Before removing any fuses, if necessary, lower the windows, adjust the steering column,
adjust the seats, unlock the doors, etc. Once fuses are removed, power controls will not
operate.
1. Pull release handle (1) and pull up release lever (2) to open the hood.
2. Release clips (A) and remove fuse box cover (1) . : Vehicle front
3.
Remove IGCT RLY fuse (F/L V IGCT RLY 50A) .
4. If you cannot identify the correct fuse, remove all the fuses. To avoid unintended reinstallation and risk of
electrical
shock and severe personal injury or death, the
dismantler should carry the fuse or fuses on his/her
person and cover the fuse box with insulated tape. 1 2

3-4.2
Cutting the Vehicle Body DANGER
• Do not cut into high-voltage related areas to avoid severe personal injury or death.
• Do not cut into the high-voltage battery to avoid severe personal injury or death.
• When removing parts, NEVER touch the high-voltage parts or the insides of the
exposed
orange-colored high-voltage cables to avoid severe personal injury or
death. Appropriate Personal Protective Equipment (PPE) must always be worn when
touching or working on high-voltage components. To avoid unintended reinstallation and risk of electrical shock and severe personal injury or
death,
the dismantler should carry the fuses or service plug on his/her person while work
is in progress. Do not cut air bag parts to avoid unintended deployment of the air bags and the risk of
severe
personal injury or death.
If approximately (10) minutes have passed since the dismantler shut down the high-voltage system [refer
to 3-4.1 High-Voltage System Shut-Down Procedure (DG–20)], then the dismantler can cut the vehicle
except
for the high-voltage battery. DO NOT cut the high-voltage battery due to possible electrocution risk and electrolyte solution
leakage. AAYIA0274ZZ
