Seats, restraints65Child restraints
Child restraint systems9 Danger
If using a rear-facing child restraint
system on the front passenger
seat, the airbag system for the
front passenger seat must be
deactivated. This also applies to certain forward-facing child
restraint systems as indicated in
the tables 3 67.
Airbag deactivation 3 63.
Airbag label 3 58.
We recommend a child restraint system which is tailored specifically to the vehicle. For further information,
contact your workshop.
When a child restraint system is being
used, pay attention to the following
usage and installation instructions as
well as to those supplied with the child
restraint system.
Always comply with local or national
regulations. In some countries, the
use of child restraint systems is
forbidden on certain seats.
Child restraint systems can be
fastened with:
● Three-point seat belt
● ISOFIX brackets
● Top-tether anchor
Three-point seat belt
Child restraint systems can be
fastened by using a three-point seat
belt. Depending on the size of the
used child restraint systems, up to
three child restraint systems can be
attached to the rear seats. After
fastening the child restraint system
the seat belt has to be
tightened 3 67.ISOFIX brackets
Fasten vehicle-approved ISOFIX
child restraint systems to the ISOFIX
mounting brackets. Specific vehicle
ISOFIX child restraint system
positions are marked in the ISOFIX
table 3 67.
ISOFIX mounting brackets are

Selecting the right system The rear seats are the most
convenient location to fasten a child
restraint system.
Children should travel facing
rearwards in the vehicle as long as
possible. This makes sure that the child's backbone, which is still very
weak, is under less strain in the event of an accident.
Suitable are restraint systems that
comply with valid UN ECE
regulations. Check local laws and
regulations for mandatory use of child
restraint systems.
The following child restraints are
recommended for the following
weight classes:Maxi Cosi Cabriofix for children up to 13 kg for group 0, group 0+ and Duo
Plus for children from 13 kg to 18 kg
in group I.
Ensure that the child restraint system to be installed is compatible with the
vehicle type.
Ensure that the mounting location of
the child restraint system within the
vehicle is correct, see following
tables.
Allow children to enter and exit the
vehicle only on the side facing away
from the traffic.
When the child restraint system is not in use, secure the seat with a seat beltor remove it from the vehicle.
Note
Do not affix anything on the child
restraint systems and do not cover
them with any other materials.
A child restraint system which has
been subjected to stress in an
accident must be replaced.
