The high DC voltage battery is located behind the rear split seats
down below a closed panel.

The battery is fan cooled and vented from the passenger side rear seat.

The hatchback curtain can be rolled in and removed easily.
The seats can be folded down.

Removing the carpet mat, the toolbox area is accessible.

The toolbox can be removed to gain access to the spare tire
and some battery-relay-electronic components.
