,thisisi ndicated by aspecial sticker. The
sticker is affixe dtotheside of th edashboard
on th efront-pa ssenger side. The sticker is
visible when you open th efront-pa ssenger
door. The front-passenger seat sensor system for
child restraint systems detect swhether a
special Mercedes-Ben zchild seat with a
transponder for automatic child seat recog-
nition has been fitted. In such cases,
PASSENGER AIRBAG OFF indicator lamp

is disabled. G
WARNING
If the 4 PASSENGER AIRBAG OFF indica-
tor lamp does not light up when the child
restraint system is fitted, the front-passenger
airbag has not been disabled. If the front-
passenger airbag deploys, the child could be
seriously or even fatally injured.
Proceed as follows:
R do not use arearward-facing child restraint
system on the front-passenger seat.
R fit arearward-facing child restraint system
on asuitable rear seat.
or

move the front-passenger seat to the rear-
most position.
R have the automatic child seat recognition
checked at aqualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. acushion, under the child
restraint system. The entire base of the child
restraint system must alwaysr est 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 leadtoi njuries.

WARNING
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 can lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF indicator
lamp to light up without there being achild
seat with transponders for automatic child
seat recognition fitted. The front-passenger
airbag will not then deploy during an accident.
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 turn the key in the ignition
lock to position 2.
ISOFIXc hild seat securing system for

tandardised securing system for
specially designed child restraint systems on
the rear seats. Securing rings for two ISOFIX
child restraint systems are fitted on the left
and right of the rear seats.
Mercedes-Ben zrecommends the use of ISO-
FIX child restraint systems listed on
(Y page 59) together with the insertion
guides included. Using insertion guides
makes it easier to fit ISOFIXc hild restraint
systems. G
WARNING
Ac hild 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
ac hild restraint system secured by the ISOFIX
child seat securing system. If the child weighs
more than 22 kg, secure the child restraint
system using athree-point seat belt. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to as uitable vehicle seat. The child cannot be
restrained 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 fittingac hild restraint
system, observe the manufacturer's installa-
tion instructions and the correct use of the
child restraint system.
For reasons of safety, only use child restraint
systems with the ISOFIX child seat securing
system on the rear seats.
We recommendt hat you use the ISOFIX child
restraint systems that have been recommen-
ded for Mercedes-Benz. 54
