Dear Nantida-san,
Sorry fo my jumping in...
This is Mizukami from Toyota Sales div.
Please find attached document.
This is manual for battery plug re-connect.
You'll find the location of the Li-Battery Service Plag is different from attached photo.
This time "Service Plag" is located under the right side of the rear seat.
But the removal procedure is the same for all car type.
If you have any questions, pls ley us know.
