Through-loading system
The concept
The cargo area can be enlarged by folding
down the rear seat backrest.
The rear seat backrest is divided into two parts
at a ratio of 60 to 40.
If equipped with through-loading system: the
rear seat backrest is divided in the ratio 40–20–
40.
The sides can be folded down separately or to‐
gether.

Hints
Danger of pinching
Before folding down the rear seat back‐
rests, ensure that the area of movement of the
backrests is clear. In particular, ensure that no
one is located in the area of movement and
that no one reaches into the area of movement
of the rear seat backrests when the middle
section is folded down. Otherwise, injury or
damage may result.◀
Lock the rear seat backrests in position
Before mounting child restraint fixing
systems, place the seat backrest as far as pos‐
sible at an angle at which the child seat is rest‐
ing firmly against the backrest and all back‐
rests can be locked securely in place.
Otherwise, the child seat will not be as stable
as it should be, and there is increased danger
of injury due to unexpected movement of the
seat backrest.◀
Opening
1. Pull the corresponding lever in the cargo
area to release the rear seat backrest.
