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.GWARNING
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 inju-
ries.
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.GWARNING
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.
GWARNING
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.
GWARNING
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.
Children in the vehicle51SafetyZProCarManuals.com

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.GWARNING
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.
GWARNING
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 secured
for 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.

passenger seatGWARNING
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.

"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
adjustment 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 complete 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.Children in the vehicle57SafetyZProCarManuals.com

Important safety notes
GWARNING
If children adjust the seats, they could
become trapped, especially if they are unat-
tended. There is a risk of injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle.
GWARNING
You could lose control of the vehicle while
driving if you:
R adjust the driver's seat, steering wheel or
mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirrors and fasten your seat
belt before starting the engine.
GWARNING
If you adjust the seat height carelessly, you or
other vehicle occupants could be trapped and
thereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is
a risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under
the lever assembly of the seat adjustment
system.GWARNING
When adjusting a seat, you or another vehicle
occupant could become trapped by the guide
rail of the seat, for instance. There is a risk of
injury.
Make sure that no one has any part of their
body within the sweep of the seat when
adjusting it.
GWARNING
The seat belt does not offer the intended level
of protection if the backrest is not in the
upright position. When braking or in the event
of an accident, you could slide underneath the
seat belt and sustain abdomen or neck inju-
ries, for example. This poses an increased risk
of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always make sure that the seat
is in the upright position.
GWARNING
The head restraints cannot provide the inten-
ded protection unless they are fitted and
adjusted correctly. There is an increased risk
of injury to the head and neck in the event of
an accident or sudden braking, for example.
Always drive with the head restraints fitted.
Ensure that the centre of the head restraints
support the back of each vehicle occupant's
head at eye level before driving off.
! To avoid damage to the seats and the seat
heating, observe the following information:
R do not spill any liquids on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.

Rclean the seat covers as recommended;
see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating mate-
rials, e.g. blankets, coats, bags, seat cov-
ers, child seats or booster seats.
! Make sure that there are no objects in the
footwell or behind the seats when moving
the seat back. There is a risk that the seats
and/or the objects could be damaged.
