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 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 key as 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 high-voltage battery will
start to be charged. A

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.
3-4 How to Handle a Damaged Vehicle
3-4.1 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 high-
voltage battery is deformed, broken or cracked, appropriate PPE must always be used and the high-voltage
battery and high-voltage components must not be touched. DANGER
• 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. A B

SRS Air Bag System Components Location
The
SRS air bag system must not be cut as there is a risk of short circuit and unintentional deployment of
the SRS However, the vehicle can be cut (except inflators) under the following conditions: • The front, side and curtain air bags have deployed.
• At least three (3) minutes have passed after the 12-volt battery negative (-) cable has beendisconnected and the high-voltage system has been shut down.
1. Crash zone sensor (located
underhood near hood latch) 2. Supplemental front air bag
modules (Infiniti Advanced Air
Bags)3. Front seat-mounted side-
impact supplemental air bags
4. Roof-mounted curtain side-
impact supplemental air bags 5. Roof-mounted curtain
side-impact supplemental air
bag inflators6. C-pillar satellite sensors
(LH shown, RH similar)
7. Seat belt buckle pretensioners 8. Seat belts with pretensioners 9. B-pillar satellite sensors
