(2) Raise the release handle of the service plug grip.

(3) Remove the service plug grip.

(4) Apply insulating tape to the socket of the service plug grip to insulate it.

5. Carry the removed service plug grip in your pocket to prevent other staff from accidentally

reinstalling it while you are dismantling the vehicle.

6. Make other staff aware that a high-voltage system is being dismantled by using the following sign: CAUTION: HIGH-VOLTAGE. DO NOT TOUCH. (see page 18).

7. If the service plug grip cannot be removed due to damage to the vehicle, remove the IG2 MAIN fuse (25A).

Caution:

This operation shuts off the HV system. Be sure to wear insulated gloves because high voltage is not shut off inside the HV battery. When it is possible to remove the service plug grip, remove it and continue the procedure.

8. After disconnecting or exposing a high-voltage connector or terminal, insulate it immediately

using insulating tape. Before disconnecting or touching a bare high-voltage terminal, wear insulated gloves.

9. Check the HV battery and nearby area for leakage. If you find any liquid, it may be strong alkaline electrolyte. Wear rubber gloves and goggles and neutralize the liquid using a saturated boric acid solution or vinegar. Then wipe up the liquid using waste rags etc.

10. If the electrolyte comes into contact with your skin, wash the skin immediately using a saturated boric acid solution or a large amount of water. If the electrolyte adheres to any article of clothing, take the clothing off immediately.

11. If the electrolyte comes into contact with your eye(s), call out loudly for help. Do not rub

your eye(s). Instead, wash the eye(s) with a dilute boric acid solution or a large amount of water and seek medical care.

12. With the exception of the HV battery, remove parts by following procedures which are

similar to conventional Toyota vehicles. For the removal of the HV battery, refer to the following pages.
