Regularly check that the permissible gross mass

When fitting a child restraint system, observe the
following:
O Always observe the correct use of the seats
and consider their suitability for attaching a
child restraint system.

O Always comply with the manufacturer's
installation and operating instructions for the
child restraint system used.
O Make sure that the child's feet do not touch
the front seat. If necessary, move the front
seat slightly forwards.
® When fitting an ISOFIX child restraint sys-
tem, also observe the following:
O When using a baby car seat in weight group
0/0+ and a rearward-facing child restraint
system in weight group 1 on a rear seat:
adjust the front seat so that the seat does
not touch the child restraint system.
O When using a forward-facing child restraint
system in weight group 1: remove the head
restraint from the respective seat, if possible.
In addition, the backrest of the child restraint
system must lie as flat as possible against
the backrest of the vehicle seat.
After the child restraint system has been
removed, replace the head restraints again
immediately and adjust them correctly.
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.
