Important safety notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren 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 pro-
tected there.
If a child younger than 12 years old and under
1.50 m in height is travelling in the vehicle:
always secure the child in a child restraint
R
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child
be sure to observe the instructions and
R
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions
always pay attention to the instructions
R
and safety notes on the automatic front-
passenger front airbag deactivation system
