Child restraint systems
Important safety notes G
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 Children less than 1.50 m tall and under
twelve years of age must always be secured
in special child restraint systems on a suit- able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R Do not transport children who are secured
in rearward-facing child restraint systems
on the front-passenger seat. Exception: if
the vehicle is equipped with automatic child
seat recognition on the front-passenger
seat and the child is secured in a child
restraint system with transponders for
automatic child seat recognition
R If you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible. When doing so,
ensure that the shoulder belt strap from the
belt outlet on the vehicle is routed towards
the front to the shoulder belt guide on the
child restraint system. Set the belt height
adjustment so that the belt strap is routed
towards the front along the bottom.
R Children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of a sudden
change of direction, heavy braking or an
accident, it would not be possible to
restrain the child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured. G
WARNING
If the child restraint system is incorrectly fit-
ted on the seat position suitable for this pur-
pose, it cannot perform its intended protec- tive function. In the event of an accident,
sharp braking or a sudden change in direction,
the child may not be held securely. There is an
increased risk of serious or even fatal injuries.
Observe the manufacturer's installation
instructions and the correct use for the child
restraint system. Make sure that the entire
surface of the child restraint system is resting
on the seat surface. Never place objects
under or behind the child restraint system,
e.g. cushions. Only use child restraint sys-
tems with the original cover designed for
them. Only replace damaged covers with gen- uine covers. G
WARNING
If the child restraint system is fitted incor-
rectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, strik- ing vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always fit child restraint systems properly,
even if they are not being used. Make sure
that you observe the child restraint system
manufacturer's installation instructions. G
WARNING
Child restraint systems or their securing sys-
tems that have been damaged or subjected to a load in an accident cannot perform their
intended protective function. In the event of
an accident, sharp braking or a sudden
change in direction, the child may not be held securely. There is an increased risk of serious
or even fatal injuries.
Immediately replace child restraint systems
that have been damaged or subjected to a
load in an accident. Have the child restraint
securing systems checked in a qualified spe-
cialist workshop before fitting a child restraint
system again. Children in the vehicle

G
WARNING
If children are left unsupervised in the vehicle, they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shift the automatic transmission out of
parking position P.
R shift the manual transmission into neutral.
R start the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children or animals unattended in the vehicle.Always keep the key out of reach of children. G
WARNING
If persons (particularly children) are exposed
to heat or cold for a prolonged period, there is a risk of serious or even fatal injuries. Never
leave persons (particularly children) unatten-
ded in the vehicle. G
WARNING
If the child restraint system is placed in direct sunlight, the parts could become very hot.
Children could be suffer burns by touching
these parts, in particular on the metallic parts
of the child restraint system. There is a risk of injury.
If you and your child leave the vehicle, always
make sure that the child restraint system is
not in direct sunlight. Cover it with a blanket, for example. If the child restraint system has
been exposed to direct sunlight, leave it to
cool down before securing the child in it.
Never leave children unattended in the vehi-
cle.
If a child is travelling in your vehicle, secure
the child using a child restraint system which is appropriate to the size, age and weight of
the child. In order to correctly secure the child
in the child restraint system, always comply
with the child restraint system manufactur-
er's installation instructions. You should pref- erably fit the restraint system to a suitable
rear seat. Make sure that the child is securedfor the trip.
Mercedes-Benz recommends that you use
the listed child restraint systems
(Y page 59). You can obtain further infor-
mation about the correct child restraint sys-
tem from any Mercedes-Benz Service Centre.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems.
You can obtain information about this at
any Mercedes-Benz Service Centre.
Child restraint system on the front-
passenger seat G
WARNING
If the front-passenger front airbag is not dis-
abled:
R a child secured in a child restraint system
on the front-passenger seat could be seri-
ously or 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 front 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 and you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible. When doing so,
ensure that the shoulder belt strap from the
belt outlet on the vehicle is routed towards
the front to the shoulder belt guide on the
child restraint system. Set the belt height
adjustment so that the belt strap is routed
towards the front along the bottom. 52

G
WARNING
Electronic devices on the front-passenger
seat can affect the function of the automatic
child seat recognition, for example:
R laptop
R mobile phone
R transponder cards such as ski passes or
access passes
The front-passenger front airbag could deploy unintentionally or not function as intended
during an accident. This poses an increased
risk of injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. If the front-passenger seat of your vehicle is
not equipped with automatic child seat rec-
ognition, this is indicated by a special sticker. The sticker is affixed to the side of the dash-
board on the front-passenger side. The
sticker is visible when you open the front-
passenger door.

nition on the front-passenger seat: if you turn
the key to position 2in the ignition lock, the
PASSENGER AIRBAG OFF indicator lamp
lights up briefly. However, the indicator lamp
has no function. It does not indicate that there is automatic child seat recognition on the
front-passenger seat. :
PASSENGER AIRBAG OFF indicator lamp
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,
PASSENGER AIRBAG OFF 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

ISOFIX child seat securing system for
the rear seats G
WARNING
ISOFIX child restraint systems do not offer
sufficient protective effect for children whose weight is greater than 22 kg who are securedusing the safety belt integrated in the child
restraint system. The child could, for example,not be restrained correctly in the event of an
accident. This poses an increased risk of
injury or even fatal injury.
If the child weighs more than 22 kg, only use
ISOFIX child restraint systems with which the child is also secured with the vehicle seat belt. Also secure the child restraint system with the
Top Tether belt, if available. 54
Children in the vehicleSafety

When installing a child restraint system, be
sure to observe the manufacturer's installa-
tion instructions and the instructions for cor- rect 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 securing a child
restraint system, always observe the manu-
facturer's installation instructions and the
correct use of the child restraint system.
For safety reasons, on the rear seats use only child restraint systems with an ISOFIX child
seat securing system which have been tested
and approved for Mercedes-Benz vehicles.
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
ISOFIX securing rings on both sides.
! 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 on
both ISOFIX securing rings :. Comply with
the child restraint system manufacturer's
instructions when installing the ISOFIX
child restraint system. ISOFIX is a standardised securing system for
specially designed child restraint systems on
the rear seats. ISOFIX securing rings :for
two ISOFIX child restraint systems are fitted
on the left and right of the rear seats.
Top Tether Important safety notes
G
WARNING
Always engage the rear seat backrests in an
upright position before installing the Top
Tether belt. Push and pull the rear seat backr- ests to check whether they are engaged cor-
rectly. The rear seat backrest may fold down if
it is not engaged correctly. The child restraint
system is then no longer supported correctly
or held in position and can no longer perform
its intended function. This can cause serious
or even fatal injuries. Example: Top Tether belt with one belt strap
Top Tether provides an additional connection
between the ISOFIX child restraint system
secured with ISOFIX and the rear seat. It Children in the vehicle

If you use a baby car seat from category 0 or 0+ or a rearward-facing child restraint system from category I
on a rear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch the
rearward-facing child restraint.
2 Vehicles with automatic child seat recognition in the front-passenger seat: a child restraint system from the
"Universal" category with a transponder for automatic child seat recognition must be fitted. The PASSENGER AIRBAG OFF indicator lamp must be lit.
3 Move the front-passenger seat as far back as possible. If you secure a child in a forward-facing child restraint
system on the front-passenger seat, ensure that the shoulder belt strap from the belt outlet on the vehicle is
routed towards the front to the shoulder belt guide on the child restraint system. Set the belt height adjust-
ment so that the belt strap is routed towards the front along the bottom. Move the front-passenger seat to the highest position and move the backrest to an almost vertical position. When doing so, ensure that the com-plete surface of the child restraint system rests against the backrest of the front-passenger seat and that the
child restraint system does not touch the roof. To do so, you may have to adjust the backrest down a little. For seats with electrical adjustment, the seat cushion angle must be set to the highest and most upright position.
