Through-loading system
The concept
The cargo area can be enlarged by folding down
the rear seat backrest.
The rear seat backrest is divided at a ratio of 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 or 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 sys‐
tems, place the seat backrest as far as possible
at an angle at which the child seat is resting
firmly against the backrest and all backrests 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 unex‐
pected movement of the seat backrest.◀
Retract the head restraint if necessary be‐
fore backrest is folded down
With folding head restraints, fold in the head re‐
straints before folding down the backrests, or
damage may result.◀
