Automatic child seat recognition on the
front-passenger seat If your vehicle does not have automatic child
seat recognition 2
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 automatic child seat recognition sensor
system on the front-passenger seat detects
whether a special Mercedes-Ben zchild seat
with automatic child seat recognition has
been fitted there. In such cases, 4
PASSENGER AIRBAG OFF indicator lamp :lights up. The front-passenger airbag is disa-
bled. G
Risk of injury
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 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.
i If the front-passenger airbag is disabled
by the automatic child seat recognition, the
following remain enabled on the front-
passenger side:
R the sidebag
R the pelvisbag
R the windowbag
R the belt tensioner
2 Vehicles without automatic child seat recognition on the front-passenger seat: 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. 48

G
Risk of injury
Do not place electronic devices on the front-
passenger seat, e.g.:
R laptops, whe nswitched 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-
ognitio nsensor 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 automatic child seat recognition fit-
ted, and the front-passenger fron tairbag will
not deploy during an accident .Itis also pos-
sible 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

ISOFIX child seat securing system for
the rear seats ISOFIX is a standardised 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. G
Risk of injury
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
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 three-point seat 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 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, 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 recommend that you use the ISOFIX child
restraint systems that have been recommen-
ded for Mercedes-Benz.
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. Children in the vehicle

R the boot lid
R the fuel filler flap G
Risk of injury
Only for the United Kingdom: if the vehicle
has been locked with the key, the double lock
function is activated as standard. It is then not
possible to open the doors from inside the
vehicle.
Therefore, do not leave any people behind in
the vehicle, particularly children, elderly peo-
ple or people requiring special assistance, if
the vehicle has been locked with the key. As
a result, they may not be able to free them-
selves in the event of an emergency. They
could be seriously or even fatally injured by
prolonged exposure to extremely high or low
temperatures, for example. In this case, res-
cuing people from outside the vehicle is diffi-
cult.
Deactivate the interior motion sensor before
you lock the vehicle with the key. The doors
can then be opened from the inside after the
vehicle has been locked from the outside with
the key. If the vehicle has been locked with KEYLESS-
GO, the doors can be opened from inside the
vehicle. G
Risk of accident
If children are left unsupervised in the vehicle,
they could:
R open a door from inside the vehicle at any
time, even if it has been locked
R start the vehicle using akey which has been
left in the vehicle
R release the parking brake
They could thereby endanger themselves and
others. Never leave children unsupervised in
the vehicle. Always take the key with you
when leaving the vehicle, even if you are only
leaving it for a short time. :

The distance from the door handle with which
you wish to lock or unlock the vehicle must
not be greater than 1 m.
When the engine is started and whilst you are
driving, KEYLESS-GO also checks whether a
valid key is in the vehicle by periodically
establishing radio contact. X
