Lexus GS 450h 2006 Dismantling Manual page 20

3. Carry the removed service plug in your pocket to prevent other staff from
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 DURING
OPERATION (see page 17).
5. If the service plug cannot be removed
due to damage to the rear portion of
the vehicle, remove the IGCT No. 1
fuse (20A: Yellow colored).
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, remove it
and continue the procedure.
6. After disconnecting or exposing a high-voltage connector or terminal, insulate it
immediately using insulation tape. Before 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.
a) If the electrolyte adheres to 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.
b) 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.
8. Remove the parts by following the procedures which are similar to the Toyota
vehicles with exception of HV battery. As for the removal of HV battery, refer to
the following pages.
