72 Occupant safety
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 rear 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
cushion and/or be fitted facing the wrong
direction. Where possible, adjust the seat
cushion inclination accordingly.
O The child restraint system must not be put
under strain by the head restraint. Adjust the
head restraints as appropriate.
O Make sure that the child's feet do not touch
the front seat. If necessary, move the front
seat slightly forwards.
Install the child restraint system.
#
The entire base of the child restraint system
must always rest on the sitting surface of the
rear seat.
Always make sure that the shoulder belt strap
#
is correctly routed from the seat belt outlet of
the vehicle to the shoulder belt guide on the
child restraint system.
The shoulder belt strap must be routed
forward from the seat belt outlet.
