We disconnected 12 volts battery in the trunk on the right side ,remove all panels and expose hybrid battery as you can see.NOTE this is different setup than on my GS 450h .Hybrid disconnect orange switch was hiding behind metal cover.That is not good design on ES 300 h ,just imagine in case of accident you can't remove hi voltage orange plug unless you have 10 mm socket ready to remove two nuts.THAT IS VERY STUPID DESIGN . GS 450 h has easy access to orange switch and RX 450 h easy access too.
