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

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–24).
•

Remove the service plug and disconnect the 12-volt battery. Refer to Alternate Procedure 2
(Remove

Service Plug) (DG–27) .
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 trunk for
12-volt battery negative cable access.
If the READY indicator does not turn off, refer to
