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 the 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, e.g. 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. G
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 a child
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. If your vehicle does not have automatic child
seat recognition 1
on the front-passenger
seat, 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. The front-passenger seat sensor system for
child restraint systems detects whether a
special Mercedes-Benz child seat with a
transponder for automatic child seat recog-
nition has been fitted. In this case,
4
PASSENGER AIRBAG OFF indicator lamp :
lights up. The front-passenger fronta irbag is
disabled.
1 Vehicles without automatic child seat recognition on the front-passenge rseat: if you turn the key to position
2int he ignition lock, the 4PASSENGER AIRBAG OFF 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. 50

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 fron tairbag 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 light sup 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:

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.
The integrated child seats are integrated into
the right and left-hand rear seat cushions. In Children in the vehicle

i
Should a side head restraint be required
for the second integrated child seat, this
can be ordered at any Mercedes-Benz
Service Centre. G
WARNING
If you do not secure the side head restraint at
the anchor points intended, it canno tprovide
the intended level of protection. It would then
not be possible to protect the child in the

abrupt change in directio nand this could
result in serious or even fatal injury to the
child.
Only attach the side head restraint to the
intended anchor points on the rea rhead
restraint.

mends that you only use side head restraints
which have been approved by Mercedes-Benz
for your vehicle.

head restraints G
WARNING
Secure the ICS padded play table and the side
head restraints in the vehicle as specified;
otherwise, they may come loose. In the event
of an accident, sudden braking or abrupt
change in direction, they could injure vehicle
occupants or cause damage to the vehicle.
When you are not using the ICS padded play
table and the side head restraints, store these
in a suitable place, such as the boot.
On vehicles with a TIREFIT kit, for example,
you can store the side head restraints in the

Child-proof locks
Important safety notes G
WARNING
Activate the child-proof locks for the rear
doors and the override switch for the rear
windows when children are travelling in the
vehicle. Otherwise, the children could open
doors or side windows while th evehicle is in
motion and injure themselves or others. G
WARNING
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. They could injure them-
selves on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys- tem could heat up and the child could burn
herself/himself on them.
If a child opens a door, the child or other per-
sons could be injured as a result. They could
get out and injure themselves or be injured by
a passing vehicle.
Also observe the notes on HOLD
.Relevant
information can be found in the index.
