Important safety notes
Basic information
BE DILIGENT
Bear in mind that negligence when securing a child in the child restraint
system may have serious 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
TWELVEYEARS OR UNDER 1.50 M IN HEIGHT, MERCEDES-BENZ
URGENTLY RECOMMENDS THAT YOU OBSERVE THE FOLLOWING:
R
Always secure the child in a child restraint system suitable for this
Mercedes-Benz vehicle.
R
The child restraint system must be appropriate to the age, weight and
size of the child.
R
The vehicle seat must be suitable for the child restraint system to be
fitted:
-
ISOFIX mounting bracket: (/page147)
-
i‑Size mounting bracket: (/page148)
-
Securing with the vehicle seat belt: (/page148)
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 fit a child restraint system to a rear seat.
THE GENERIC TERM CHILD RESTRAINT SYSTEM
THE GENERIC TERM CHILD RESTRAINT SYSTEM IS USED IN THIS OWN‐
ER'S MANUAL. A CHILD RESTRAINT SYSTEM IS, FOR EXAMPLE:
R
a baby car seat
R
a rearward-facing child seat
R
a forward-facing child seat
R
a child booster seat – Mercedes-Benz recommends using a child booster
seat with a seat backrest and seat belt guide.
OBSERVE LAWS AND LEGAL REQUIREMENTS
Always observe the legal requirements when using a child restraint system in
the vehicle.
Make sure that the child restraint system is approved in accordance with the
valid test specifications and guidelines. Further information can be obtained
at a qualified specialist workshop. Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this purpose.
