GWARNING
Electronic devices on the front-passenger
seat can affect the function of the automatic
child seat recognition, for example:
R laptop
R mobile phone
R transponder cards such as ski passes or
access passes
The front-passenger front airbag could deploy
unintentionally or not function as intended
during an accident. This poses an increased
risk of injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat.
If the front-passenger seat of your vehicle
does not have automatic child seat recogni-
tion, this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. The sticker is
visible when you open the front-passenger
door.
Vehicles without automatic child seat recog-
nition on the front-passenger seat: if you turn
the key to position  2 in the ignition lock, the
PASSENGER AIRBAG OFF indicator lamp
lights up briefly. However, the indicator lamp
has no function. It does not indicate that there
is automatic child seat recognition on the
front-passenger seat.
The sensor system for child restraint systems
in the front-passenger seat detects whether
a special Mercedes-Benz child seat with a
transponder for automatic child seat recog-
nition has been fitted. In this case,
PASSENGER AIRBAG OFF indicator lamp  :
lights up. The front-passenger front airbag is
disabled.
i If the front-passenger front airbag is dis-
abled by the automatic child seat recogni-
tion, the following remain enabled on the
front-passenger side:
R the sidebag
R the windowbag
R the belt tensioner
ISOFIX child seat securing system for
the rear seats
GWARNING
ISOFIX child restraint systems do not offer
sufficient protective effect for children whose
weight is greater than  22 kg who are secured
using the safety belt integrated in the child
restraint system. The child could, for example,
not be restrained correctly in the event of an
accident. This poses an increased risk of
injury or even fatal injury.
If the child weighs more than 22 kg, only use
ISOFIX child restraint systems with which the
child is also secured with the vehicle seat belt.
Also secure the child restraint system with the
Top Tether belt, if available.
