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.
The left and centre seat backrests are engaged and joined together.
You can lock the centre seat backrest. The centre seat backrest can then be folded forwards only together with the left seat backrest.
The release catch of the centre seat backrest will be locked.
