3-2 Personal Protective Equipment (PPE) and Insulated Tools
3-2.1 Personal Protective Equipment (PPE) Protective Wear Control
Perform an inspection of the Personal Protective Equipment (PPE) items before beginning work. Do not use
any damaged PPE items.
3-2.2 Daily Inspection
This inspection is performed before and after use. The worker who will be using the items should perform
the inspection and check for deterioration and damage.• Insulated rubber gloves should be inspected for scratches, holes and tears. (Visual check and airleakage test)
• Insulated safety boots should be inspected for holes, damage, nails, metal pieces, wear or other problems on the soles. (Visual check)
• Insulated rubber sheet should be inspected for tears. (Visual check)
3-2.3 Insulated Tools
When performing work at locations where high voltage is applied (such as terminals) , use insulated tools
meeting 1,000V/300A specifications.
3-3 Discharge Procedures
DANGER
Do not perform this procedure if the battery is damaged. If you are unsure of battery
damage, use extreme caution and wear appropriate Personal Protective Equipment (PPE) .
High voltage battery discharging must take place before dismantling. Sufficient discharging can be achieved
by following these steps. 1. Place the shift selector into the Park (P) position
2. Apply the parking brake.
3. Set wheel chocks to ensure the vehicle is completely stopped.
4. Fasten the driver seat belt and close the driver door.
5. Apply foot brake and press the ignition switch to turn the system ON. Confirm READY
indicator in instrument cluster turns ON.a. If the engine starts, leave the engine on until idling stops.
b. If the engine does NOT start, move on to next step.
6. Remove the shift lock cover (A) using a suitable tool.
7. Push down the shift lock (B) as shown in the illustration.
8. Push the shift selector button (C) and move the shift selector to Neutral (N) position (D) while holding down
the shift lock.
NOTE:
DO NOT press accelerator or foot brake after
moving the shift selector to the Neutral (N)
position. Otherwise high voltage battery will
start to be charged.

•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 thevehicle.
• Be sure to check the READY indicator (1) in the instrument cluster, and verify that the READY indicator is off and the high voltage system is stopped.
• After the high voltage system is shut down, please wait for approximately ten (10) minutes for complete discharge of the high voltage capacitor. While waiting, do not
operate any vehicle functions.
• Remove the 12-volt battery negative (-) terminal and wait for 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 for
three (3) minutes. 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 DC/DC converter
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 (Remove Fuses) (DG–23).
• Remove the service plug and disconnect the 12-volt battery. Refer to
Alternate Procedure 2
(Remove Service Plug) (DG–25)
.
DG–20

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. Check the READY indicator (A) status in the instrument cluster. If it is on, the high voltage systemis active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch (B) once to turn OFF the high voltage system. Then verify whether the READY indicator (A) is off.
If the READY indicator (A) does not turn off, continue to the next steps to open the trunk for
12-volt battery negative cable access.
4.
If possible, keep the Infiniti Intelligent Key at least 5 meters
(16 feet) away from the vehicle (except as noted below) .
5. Open the trunk using any of the following: a. push-button switch (C) on the lower LH side ofthe instrument panel.
b. trunk button (D) on the Infiniti Intelligent Key [press for longer than one (1) second].
c. trunk open request switch (E) (located above license plate)*.
d. with the mechanical key (F) housed inside the Infiniti Intelligent Key.
Method Shift Selector Position Ignition Switch Status
a P or N Any
b P OFF
c* Any Any d Any Any
* You must have the Infiniti Intelligent Key within approximately 1 meter (3 feet) range of trunk request switch
to use the trunk open request switch function.

Alternate Procedure 1 (Remove Fuses)
NOTE: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 notoperate.
1. Pull release handle (A) to open the hood.
2. Remove fuse box cover (B) .
3. Remove 80A fuse (C) (black) .
4. If you cannot identify the fuse (C) , remove all fuses in the fuse box.
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.

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 dismantler 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 dismantler 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. Check the READY indicator (A) status in the instrument cluster. If it is on, the high voltage systemis active.
2. Place the shift selector in the Park (P) position.
3. Push the ignition switch (B) once to turn OFF the high voltage system. Then verify whether the READY indicator (A) is off.
If the READY indicator (A) does not turn off, continue to the next steps to open the trunk for
12-volt battery negative cable access.
