Children in th
evehicle Child restraint systems
Important safety notes G
WARNING
To reduc ethe riskofs erious or even fatal
injury to the child in the event of asudden
change in direction, braking or an accident:
R children less than 1.50mt all and under
twelve years of age must alway sbesecured
in special child restraint systems on asuit-
able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R do not secure children less than 1.50mt all
or unde rtwelve years of age on th efront-
passenger seat .Exception: the vehicl eis
equipped with automatic child sea trecog-
nition on the front-passenger seat and the
child is secured in achild restraint system
with transponders for automatic child seat
recognition.
R if you secure aforward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
R children must never travel sitting on the lap
of another occupant .Due to the forces
which occur in the event of asudden
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
The child restraint system cannot perform its
protective function if it is not correctly fitted
to as uitable 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 achild restraint
system, observe the manufacturer's installa- tion instructions and the correct use of the
child restraint system.
Child restraint systems should be fitted to the
rear seats. Children are generally better pro-
tected there.
The entire base of the child restraint system
must alway
srest on the seat cushion. There-
fore, never place objects, e.g. acushion,
under the child restraint system.
Only use child restraint systems with the orig-
inal cover designed for them. Only replace
damaged cover swith genuine Mercedes-Benz
covers.
We recommend the use of child restraint sys-
tems which have been approved for
Mercedes-Benz vehicles.
If ac hild is travellin ginyour vehicle, secure
the child using achild restraint system which
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 asuitable rear seat. Make
sure that the child is secured in achild
restraint system throughout the trip.
Mercedes-Benz recommends that you only
use the child restraint systems listed at
(Y page 59).
You can obtain further information about the
correct child restraint system from any
Mercedes-Benz Service Centre.
i It is advisable to use Mercedes-Benz care
product stoclean child restraint systems.
You can obtain information about this at
any Mercedes-Benz Service Centre. G
WARNING
Do not leave children unsupervised in the
vehicle, even if they are secured in achild
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- Children in the vehicle

Important safety notes
Xenon bulbs If your vehicle is equipped with xenon bulbs,
you can recognise this by the following: the
cone of light from the xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before startingt he engine. G
DANGER
Xenon bulbs carry ahigh voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric con- tacts on xenon bulbs. Therefore, never
remove the cover from xenon bulbs.
Do not change xenon bulbs yourself, but have
them replaced at
aqualified specialist work-
shop which has the necessary specialist
knowledge and tools to carry out the work
required.
Mercedes-Ben zrecommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs There are bulbs other than the xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y
page 122). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
