If this is the case, the vehicle occupant
R
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 trunk/cargo com‐
R
partment cannot be restrained by the
seat backrest.
Make sure that the seat backrest and

the rear bench seat/rear seat are
engaged before every trip.
If the rear seat backrest is not engaged and

When installing a belt-secured child restraint
system, observe the following:
O Always comply with the manufacturer's
installation and operating instructions for
the child restraint system used.
O When using a category 0/0+ baby car
seat and a category I rearward-facing
child restraint system on a rear seat:
adjust the front seat so that the seat does
not touch the child restraint system.
O When using a category I forward-facing
child restraint system: remove the head
restraint from the respective seat, if possi‐
ble.
After removing the child restraint system,
replace the head restraints again immedi‐
ately and adjust them correctly.
O The backrest of the forward-facing child
restraint system must, as far as possible, be
resting on the seat backrest of the rear
seat.
O For certain child restraint systems in weight
category II or III, there may be restrictions in
the maximum size setting, e.g. due to possi‐
ble contact with the roof.
O The child restraint system must not be put
under strain between the roof and the seat
cushion and/or be installed facing the
wrong direction. Where possible, adjust the
seat cushion inclination accordingly.
