WARNING
If the ICS padded playt able has been incor-
rectly fitted to the integrated child seat, it
cannot perform its intended protective func-
tion. Achild therefore cannot be restrained in
the event of an accident, heavy braking or a
sudden change of direction. In addition, the
ICS padded playt able couldbecome loose
and be thrown around, endangering vehicle
occupants. This pose sanincreased risk of
injury or even fatal injury.
Fit the ICS padded playt able as described.
After fitting the ICS padded playt able,make
sure that it is secure dcorrectly. For safety
reasons, only use the ICS padded playt able
that has been tested and approved for your
vehicle.
The ICS padded playt able is only suitable for
use with the folded-out integrated child seat.
On the rear seats with an integrated child
seat, only use the ICS padded playt able that
is recommende dfor Mercedes-Benz vehicles.
Only use the ICS padded playt able with its
original cover. Withou tthe original cover, the

Use the ICS padded playt able in accordance
with the instructions in the table in the "Inte-
grated child seat( ICS)"section (Y page62).
Note that children under two years old and
children who weigh less than 12.5 kg require ad ifferent and suitable child restraint system.
Information about other child restraint sys-
tems is available at any Mercedes-Benz Ser-
vice Centre.
You must not use the integrated child seat
with ICS padded playt able asadirect attach-
ment to ababyc ar seatf or which abody
weight of up to 10 kg is permissible. Note that
children younger than 24 months old require
