Warning symbol for a rearward-facing child
restraint system G
WARNING
If the front-passenger airbag is not disabled:
R a child secured in a child restraint system
on the front-passenger seat could be seri-
ously and even fatally injured by the front-
passenger airbag deploying. This is espe-
cially a risk if the child is in the immediate
vicinity of the front-passenger airbag when
it deploys.
R never secure a child on the front-passenger
seat in a rearward-facing child restraint sys-
tem. Only secure a rearward-facing child
restraint system on a suitable rear seat.
R always move the front-passenger seat to
the rearmost position if you secure a child
in a forward-facing child restraint system
on the front-passenger seat.
The front-passenger airbag is not disabled:
R on vehicles without automatic child seat
recognition on the front-passenger seat
R in vehicles with automatic child seat rec-
ognition in the front-passenger seat, if no
special child restraint system with trans-
ponders for automatic child seat recogni-
tion in the front-passenger seat has been
fitted
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat, if the PASSENGER AIRBAG OFF indicator lamp

is not lit.
To make you aware of this danger, a corre-
sponding warning sticker has been affixed on
the dashboard and on both sides of the sun
visor on the front-passenger side.
Information about recommended child
restraint systems is available at any
Mercedes-Benz Service Centre.

Problems with child seat recognition
Problem Possible causes/consequences and
M Solutions
The
4 PASSENGER
AIRBAG OFF indicator
lamp on the centre con-
sole is lit. As
pecial Mercedes-Benz child seat with a transponder for auto-
matic child seat recognition has been fitted to the front-passenger
seat. The front-passenger airbag has therefore been disabled as
desired. G
Risk of injury
There is no child seat fitted to the front-passenger seat. Automatic
child seat recognition is malfunctioning.
It is also possible that the 6SRS warning lamp lights up and/
or the 4PASSENGER AIRBAG OFF indicator lamp does not light
up briefly when you switch the ignition on.
X Remove electronic equipment from the front-passenger seat,
e.g.
R
laptop
R mobile phone
R cards with transponders, such as ski passes or access cards
If the 4 PASSENGER AIRBAG OFF indicator lamp is still lit:
X Visit a qualified specialist workshop. Integrated child seat

WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of a sudden
change in direction, braking or an accident:
R you must follow the manufacturer's instal-
lation instructions for the child seat when
fitting the integrated child seat (ICS) pad-
ded play table and side head restraint and
when fastening the seat belt.
R do not modify the integrated child seat, the
ICS padded play table or the side head
restraint. Do not use protective covers.
R make sure that the ICS padded play table
and the side head restraints do not become trapped or damaged. This could happen
when you
- close the doors
- adjust the seat
- store the ICS padded play table and the
side head restraints
- transport heavy objects
R replace the integrated child seat, the pad-
ded play table and the side head restraints
if these were damaged or subjected to
heavy loads during an accident.
R note: children who weigh less than
12.5 kg require a different child restraint
system. Information about other child
restraint systems is available from any
Mercedes-Benz Service Centre.
R the vehicle's rear seat backrest must be
locked in position.
