▌Securing the child restraint system with the
seat belt on the front passenger seat
When fitting a belt-secured child restraint system
on the front passenger seat, always observe the
following:
O Observe the notes on rearward-facing and
forward-facing child restraint systems on the
front passenger seat ( page 73).
/
O Observe the child restraint system manufac-
turer's installation and operating instructions.
O For a child restraint system in the "Universal"
or "Semi-Universal" category, make sure that
the system has been approved for the vehicle
seat.
Observe the notes under "Suitability of seats
for attaching belt-secured child restraint sys-
tems" ( page 69).
/
O When using a forward-facing child restraint
system in weight category I: remove the head
restraint from the respective seat, if possible.
After the child restraint system has been
removed, replace the head restraints again
immediately 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 front
passenger seat.
O If the head restraint of the child seat cannot
be fully extended when it is installed in the
vehicle, this will result in restrictions on the
maximum size setting for child restraint sys-
tems in weight category II or III.
Contact with the roof when the head
restraint is fully extended and locked in place
will not result in any restrictions on use.
O The child restraint system must not be put
under strain between the roof and the seat

under strain by the head restraint. Adjust the

behind the child restraint system.
Set the front passenger seat as far back as
#
possible and move the seat into the highest
position if possible.
Fully retract the seat cushion length adjust-
#
ment.
Adjust the seat cushion inclination so that the
#
front edge of the seat cushion is in the highest
position and the rear edge of the seat cushion
is in the lowest position.
Set the seat backrest to the most vertical
#
position possible.
Install the child restraint system.
#
The entire base of the child restraint system
must always rest on the sitting surface of the
front passenger seat.
