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
45 indicator lamp lights up briefly but
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, 45
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 G
WARNING
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 achild restraint system secured by the ISOFIX
child seat securing system. If the child weighsmore than 22 kg, secure the child restraint
system with the vehicle seat belt as well. In
addition, when fitting a child restraint system, be sure to observe the manufacturer's instal-
lation instructions and the instructions for
correct use of the child restraint system. G
WARNING
The child restraint system cannot perform its protective function if it is not correctly fitted
to a suitable vehicle seat. The child cannot berestrained in the event of an accident, heavy
braking or sudden changes of direction. The
child could be seriously or even fatally injured.
For this reason, when fitting a child restraint
system, be sure to observe the manufactur-
er's installation instructions and the instruc-
tions for correct use of the child restraint sys-
tem.
For safety reasons, when installing child
restraint systems on the rear seats, only use
child restraint systems with the ISOFIX child
seat securing system, which are specially tes- ted and approved for Mercedes-Benz vehi-
cles.
An incorrectly fitted child restraint system
could come loose and seriously or even fatally Children in the vehicle

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
WARNING
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.
! When fitting the ISOFIX child restraint
system, make sure that the seat belt for the centre seat does not get trapped. Other-
wise, the seat belt could be damaged. X
Install the ISOFIX child restraint system.
Comply with the manufacturer's instruc-
tions when installing the ISOFIX child
restraint system.
ISOFIX is a standardised securing system for specially designed child restraint systems on
the rear seats. Securing rings :for two ISO-
FIX child restraint systems are fitted on the
left and right of the rear seats. Top Tether Important safety notes
G
WARNING
Make sure that the rear seat backrest is fully
locked. When the red lock verification indica- tors on the left and right are no longer visible,
the rear seat backrests are locked. If the rear
seat backrests are not locked, occupants
could be injured in the event of an accident,
e.g. by objects that are thrown forward from
the luggage compartment. Top Tether provides an additional connection
between the ISOFIX child restraint system
secured with ISOFIX and the rear seat. It
helps reduce the risk of injury even further.
The Top Tether anchorage points are fitted on
the rear side of the rear seat backrests.
X Vehicles with adjustable head
restraints: move the head restraint
upwards.

restraint between the two head restraint
bars. 54
