Lexus GS450h Dismantling Manual page 20

3. Carry the removed service plug grip in your pocket to prevent other staff from
accidentally reinstalling it while you are dismantling the vehicle.
4. 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 17).
5. If the service plug grip cannot be removed due to damage to the vehicle, remove the
IG2 MAIN fuse (20 A).
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.
6. 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.
7. 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.
8. 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.
9. 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.
10. With the exception of the HV battery, remove parts by following procedures which are
similar to conventional Lexus vehicles. For the removal of the HV battery, refer to the
following pages.
