ISOFIX chil dseat securing system for
the rear seats 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
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
WARNING
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
WARNING
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.
! When fitting the child restraint system,
make sure that the seat belt for the centre
seat does not get trapped. Otherwise, the
seat belt could be damaged.
ISOFIX is a standardised securing system for
specially designed child restraint systems on
the rear seats. The ISOFIX securing rings for
two ISOFIX child restraint systems are fitted
on the left and right of the rear seats. :

seat Important safety notes
G
WARNING
If the ICS padded play table is not installed
and used correctly on the integrated child
seat, it cannot provide the intended protec-
tion. It would then not be possible to restrain
the child in the even tofanaccident, sudden
braking or abrup tchange in direction and this
could result in serious or even fatal injury to
the child. For this reason, observe the follow-
ing description when fitting the ICS padded
play table: The ICS padded play table is only suitable for
use together with the folded out integrated
child seat.
On the rear seats, only use the ICS padded
play table which is recommended for

could come loose and seriously or even fatally
injure the child or other vehicle occupants.
After fitting the ICS padded play table, make
sure that it is secured correctly. G
WARNING
Do not modify the ICS padded play table, inte-
grated child seat or seat belts. The ICS pad-
ded play table must not be used without a
cover. The cover must not be removed from
the ICS padded play table or replaced with a
cover from another manufacturer. Otherwise,
the official approval is invalidated and the
padded play table's protective function could
be restricted.
Do not subject the ICS padded play table to
unnecessary heat or expose it to direct sun-
light. Parts of the ICS padded play table could
heat up and the child could burn itself on
them. G
WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of a sudden

Driving safety systems overview
In this section, you will find information about
the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
R BAS (Brake AssistSystem)
R COLLISION PREVENTION ASSIST (BAS
PLUS and distance warning signal)
R Adaptive brake lamps
R ESP ®
(Electronic StabilityProgram) R

G
WARNING
The risk of an accident is significantly
increased by driving too fast. This is particu-
larly the case when cornering as well as on
wet or slippery roads or when driving too close
to the vehicle in front.
The driving safety systems described in this
section can neither reduce this risk nor over-
ride the laws of physics.
For this reason, always adapt your driving
style to the prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and objects on the road.
If you fail to adapt your driving style, the driv-
ing safety systems can neither reduce the risk
of accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are responsi-
ble for the distance to the vehicle in front, for
vehicle speed and for braking in good time.
Always adapt your driving style to suit the
prevailing road and weather conditions as
well as the traffic conditions, and maintain a
safe distance from the vehicle in front. Drive
carefully.
i Please note that the driving safety sys-
tems described only work as effectively as
possible when there is adequate contact
between the tyres and the road surface.
Pay particular attention to the information
regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and
tyres" section (Y page 292).
In wintry driving conditions, always use
winter tyres (M+S tyres) and if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. 62

a result, they may not be able to free them-
selves in the event of an emergency. As a
result, they could be seriously or even fatally
injured by prolonged exposure to extremely
high or low temperatures, for example. In this
case, rescuing people from outside the vehi-
cle is difficult.
