Can anyone help with instructions for removing the drop down switch/button panel where the fuel filler mirror adjusters are. A wiring diagram would also be very useful for 2007 GS450H.

Although an old post it should be pointed out that the GS450H does not have an alternator. The car does not need to be driven to charge the battery. Just leaving it in ready mode, and park will charge it.

The 12 volt battery is an AGM battery and are notorious for not recovering well from a complete discharge.

Sounds like this could be antifreeze "the wrong antifreeze". The genuine Toyota/Lexus supper long life coolant "SLLC" is pink or red in color. This could be from either an engine coolant  or a transmission coolant leak. In either case this needs fixing quickly.
