Children in the vehicle
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 and under 5 ft
(1.50 m) in height is traveling in the vehicle:
R
always secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child
R
be sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions
R
be sure to observe the instructions and
safety notes on the "Occupant classifica-
tion system (OCS)" (Y page 51)
