Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
a child restraint system on a rear seat. Children
are generally better protected there.
If a child younger than twelve years old and
under 1.50 m in height is travelling in the vehi-
cle:
always secure the child in a child restraint
R
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
be sure to observe the instructions and safety
R
notes in this section in addition to the child
restraint system manufacturer's installation
instructions.
always pay attention to the instructions and
R
safety notes on the automatic front-
passenger front airbag deactivation system
(
page 51).
