Important safety notes
Basic information
Be diligent
Bear in mind that negligence when securing a
child in the child restraint system may have seri-
ous consequences. Always be diligent in securing
a child carefully before every journey.
Never allow babies and children to travel sitting
on the lap of another vehicle occupant.
To improve protection for children younger than
12 years old or under 5 s (1.50 m) in height,
Mercedes-Benz recommends you observe the fol-
lowing information:
= Always secure the child in a child restraint sys-
tem suitable for this Mercedes-Benz vehicle.
= The child restraint system must be appropriate
to the age, weight and size of the child.
= The vehicle seat must be suitable for the child
restraint system to be installed:
Accident statistics show that children secured on
the rear seats are generally safer than children secured on the front seats. For this reason,
Mercedes-Benz strongly advises that you install a
child restraint system on a rear seat.
