Suitable child restraint systems for the transport
of children
Information on the advantage of a rearward-facing
child restraint system
Transport a baby in a suitable rearward-facing
child restraint system only. It is also preferable to transport a small child in a suitable rearward-
facing child restraint system. In this case, the child sits in the opposite direction to the directionof travel and faces backwards.
Babies and small children have comparatively
weak neck muscles in relation to the size and
weight of their head. The risk of injury to the cer-vical spine during an accident can be reduced in a
rearward-facing child restraint system.
Securing the child restraint system
Adjusting the seat correctly
When installing a child restraint system on the le"s
or right rear seat, always observe the following:
Make sure that the child\bs feet do not touch the front seat. If necessary, move the front seat slightly forwards.
If the head restraint of the child restraint system
cannot be fully extended when it is installed in the
vehicle, this will result in restrictions on the maxi- mum size setting for certain child restraint sys-
tems. Observe the child restraint system manu-facturer\bs installation instructions.
\bContact with the roof when the head restraintis fully extended and locked in place will not
result in any restrictions on use.
® When installing an ISOFIX child restraint
system, also observe the following:
When using a rearward-facing child restraint
system on a rear seat: adjust the front seat so
that it does not touch the child restraint sys-
tem.74Safely transporting children in the vehicle
