If the rear bench seat/rear seat and seat backrest are not engaged they could fold forwards, e.g. when braking suddenly or in the event of an accident.
If this is the case, the vehicle occupant would be forced into the seat belt by the rear bench seat/rear seat or by the seat backrest. The seat belt cannot protect as intended and could result in additional injury.
Objects or loads in the boot/load compartment cannot be restrained by the seat backrest.
To enlarge the load compartment, you can adjust the seat backrests so that they are ten degrees steeper (cargo position).
