The automatic child seat recognition sensor
system on the front-passenger seat detects
whether a special Mercedes-Benz child seat
with automatic child seat recognition has
been fitted. In such cases, 4PASSENGER
AIRBAG OFF warning lamp :lights up. The
front-passenger front airbag is disabled. G
Risk of injury
If the 4 PASSENGER AIRBAG OFF warning
lamp does not light up when the child restraint
system is fitted, the front-passenger front air-
bag has not been disabled. If the front-
passenger front airbag is deployed, the child
could be seriously or even fatally injured.
Proceed as follows:
R do not use a rearward-facing child restraint
system on the front-passenger seat.
R fit a rearward-facing child restraint system
on a suitable rear seat.
or
R only use a forward-facing child restraint
system on the front-passenger seat and
move the front-passenger seat to its rear-
most position.
R have the automatic child seat recognition
checked at a qualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects (such as a cushion) under the child
restraint system. The entire base of the child restraint system must always rest on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could lead to injuries.
i The windowbag, the sidebag and the belt
tensioner on the front-passenger side are
still active even if the front-passenger front
airbag is disabled by the automatic child-
seat recognition on the front-passenger
seat. G
Risk of injury
Do not place electronic devices on the front-
passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes or
access cards
Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. This could lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF warning lamp
to light up without there being a child seat
with automatic child seat recognition fitted.
This means that the front-passenger front air-
bag will not deploy during an accident. It is
also possible that the 6SRS warning lamp
lights up and/or the 4PASSENGER AIR-
BAG OFF warning lamp does not light up
briefly when you turn the key in the ignition
lock to position 2.

ISOFIX child seat securing system in
the rear compartment ISOFIX is a standardised securing system for
specially designed child restraint systems on
the rear seats. Securing rings for two child
restraint systems are fitted on the left and
right of the rear seats. G
Risk of injury
A child restraint system secured by the ISOFIX
child seat securing system does not provide
sufficient protection for children weighing
more than 22 kg. For this reason, do not
secure children weighing more than 22 kg in
a child restraint system secured by the ISOFIX
child seat securing system. If the child weighs
more than 22 kg, secure the child restraint
system using a lap-shoulder belt. G
Risk of injury
The child restraint system cannot perform its
protective function if it is not correctly fitted
to a suitable vehicle seat. The child cannot be
restrained in the event of a sudden change of
direction, heavy braking or an accident. This
may lead to serious or even fatal injuries. For
this reason, when fitting a child restraint sys-
tem, observe the manufacturer's installation instructions and the correct use of the child
restraint system.
On the rear seats, only use child restraint sys-
tems with an ISOFIX child seat securing sys-
tem which have been recommended for use
in Mercedes-Benz vehicles.
An incorrectly fitted child restraint system
could come loose and seriously or even fatally
injure the child or other vehicle occupants.
When fitting the child restraint system, always
make sure that it is engaged correctly in the
securing rings on both sides.
G
Risk of injury
Please note that if child restraint systems, or
their retaining systems, are damaged or sub-
jected to a load in an accident, they may not
be able to provide their protective function.
This could result in serious or even fatal inju-
ries to the secured child in the event of an
accident, heavy braking or a sudden change
in direction.
For this reason, have child restraint systems
and their anchorages which have been dam-
aged or subjected to a load in an accident
checked immediately at a qualified specialist
workshop. Occupant safety

When fitting the child restraint system,
make sure that the seat belt for the centre
seat does not become trapped. Otherwise,
it could be damaged. When installing the child seat, fold protective
cap 2of retaining loop 1inwards.
Top Tether
Top Tether provides an additional connection
between the child restraint system secured
with ISOFIX and the rear bench seat. It helps
reduce the risk of injury even further.

Integrated child seat* The child seats are integrated into the right-
and left-hand sides of the seats of the rear
bench seat. In conjunction with the compo-
nents listed in the following table, they com-
ply with the legal requirements of
ECE R 44.04.

Mercedes-Benz recommends the integrated
child seat for children with a body weight of
12.5 to 36 kg.
For children weighing between approximately
12.5 kg and 18 kg, you must always also use
an additional padded table* and a side head
restraint which have been specially approved
for the integrated child seat. G
Risk of injury
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 padded table* and side head
restraint and when fastening the seat belt.
R do not modify the integrated child seat, the
padded table* or the side head restraint. do
not use protective covers.
