Important safety notes

WARNING
When expanding the cargo volume, always fold the seat backrests fully forward.
Unless you are transporting cargo, the seat backrests must remain properly locked in the upright position.
In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the vehicle. This can cause injury to vehicle occupants unless the items are securely fastened in the vehicle.
Always use the cargo tie-down rings.

The left-hand and right-hand rear seat backrests can be folded down separately to increase the trunk capacity.
