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.
3-2.4 Discharge Procedures
Do not perform this procedure if the high voltage battery is damaged. If you are unsure of
battery damage, use extreme caution and always wear appropriate Personal Protective
Equipment (PPE) when working on high voltage components.
Li-ion 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 immobilized.
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 the 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) using mechanical keyas shown in the illustration.
8. Push the shift selector button (C) and move the shift selector to the 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 Li-ion battery will start to becharged.
NOTE:
The engine must not be running at this time. If the engine has restarted, repeat the
previous steps.
9. Release the parking brake.
10. Unbuckle the seat belt and open the driver door. The READY
indicator should remain ON
and the engine should not be running.
11. Turn ON electric devices such as headlamps, A/C (set to the coldest temperature) and rear window defogger to discharge the high voltage battery. Discharge is complete when the READY
indicator (B) (green) turns OFF, and the hybrid system warning indicator (C) (orange)
turns ON.
12. Move shift selector into the Park (P) position and press the ignition switch (A) to turn the system OFF.
Please contact following number if the vehicle could not be discharged. • 1-800-662-6200 (US) or 1-800-361-4792 (Canada)
• Hours of operation are 8am - 5pm (Monday-Friday) Eastern, Central and Pacific time zones.

3-3 How to Handle a Damaged Vehicle
3-3.1 High Voltage System Shut-Down Procedure
Any of the following procedures can shut down the high voltage system. The dismantling operation can only
begin after shutting down the high voltage system. If the vehicle is heavily damaged, for example the Li-ion
battery is deformed, broken or cracked, appropriate PPE must always be used and the Li-ion battery and
high voltage components must not be touched.
•Failure to properly shut down the high voltage system before the dismantling
procedures are performed will result in serious injury or death from electrical shock.
To prevent serious injury or death, NEVER touch high voltage harnesses or components
without always wearing appropriate Personal Protective Equipment (PPE) . PPE must
always be worn when touching or working on high voltage components.
•When contact with high voltage components or high voltage harnesses is
unavoidable, or when there is risk of such contact, you must always wear appropriate
PPE. PPE must always be worn when touching or working on high voltage components.
•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 12V battery negative (-) terminal, wait at least three (3) minutes to discharge the air bag capacitor. Even though the
12V 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 12V 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 systemcontinuously.
Before disconnecting the 12V 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 12V battery is disconnected,
power controls will not operate. DG–20

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 12V battery. Refer to
Primary Procedure (DG–21).
• Disconnect the underhood fuse panel terminal connector for the high voltage control system and disconnect the 12V battery. Refer to
Alternate Procedure 1 (Disconnect Underhood Fuse
Panel) (DG–24)
.
• Remove the service plug and disconnect the 12V battery. Refer to
Alternate Procedure 2
(Remove Service Plug) (DG–27)
.
Primary Procedure
NOTE:
Before disconnecting the 12V battery terminal, if necessary, lower the windows, adjust the
steering column, adjust the seats, unlock the doors, etc. Once 12V 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
12V battery negative cable access.
If the READY indicator does not turn off, refer to
Alternate Procedure 1 (Disconnect Underhood Fuse
Panel) . (DG–24)
4. If possible, keep the Infiniti Intelligent Key at least5 meters (16 feet) away from the vehicle (except to
open the trunk as noted below) .
