is appropriate to the size
,age and weight of
the child and recommended for Mercedes-
Benz vehicles. You should preferably fit the
restraint system to a suitable rear seat. Make
sure that the child is secured in a child
restraint system throughout the trip.
Mercedes-Benz recommends that you only
use the child restraint systems listed at
(Y page 63).
You can obtain further information about the

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.R elevant
information can be found in the index. G
WARNING
Unsecured or incorrectly positioned loads
increase the risk of injury for children and all
other occupants in the event of:
R an accident
R a braking manoeuvre
R a sudden change of direction
Do not carry heavy or hard objects in the vehi-
cle interior unless they are secured. You will find further information under "Loading guide-
lines" in the index.

restraint system G
WARNING
If the front-passenger airbag is no tdisabled:
R a child secured in a child restraint system
on the front-passenge rseat could be seri-
ously and even fatally injured by the front-
passenger airbag deploying. This is espe-
cially a risk if the child is in the immediate
vicinity of the front-passenger airbag when
it deploys.
R never secure a child on the front-passenger
seat in a rearward-facing child restraint sys-
tem. Only secure a rearward-facing child
restraint system on a suitable rear seat.
R always move the front-passenger seat to
the rearmost position if you secure a child
in a forward-facing child restraint system
on the front-passenger seat. The front-passenger airbag is not disabled:
R
on vehicles without automatic child seat
recognition on the front-passenger seat
R in vehicles with automatic child seat rec-
ognition in the front-passenger seat, if no
special child restraint system with trans-
ponders for automatic child seat recogni-
tion in the front-passenger seat has been
fitted
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat, if the
PASSENGER AIRBAG OFF indicator lamp
4 is not lit.
To make you aware of this danger, a corre-
sponding warning sticker has been affixed on
the dashboard and on both sides of the sun
visor on the front-passenger side.
Information about recommended child
restraint systems is available at any
Mercedes-Benz Service Centre.
Automatic child seat recognition on the
front-passenger seat 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.
1 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. Children in the vehicle
57Safety Z

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 such cases,
PASSENGER AIRBAG OFF indicator lamp
4: lights up. The front-passenger airbag
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 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 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.
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.58
