In addition, they may operate vehicle equip-
ment and become trapped. 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 unattended in the vehicle. 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.
Always ensure that all vehicle occupants have their seat belts fastened correctly and are sit-
ting properly. Particular attention must be
paid to children.
Observe the safety notes on the seat belt
(Y page 42) and the information on the cor-
rect use of the seat belt (Y page 43).Child restraint system
If you fit a rearward-facing child restraint sys- tem to the centre rear seat, the rear arm restmust be folded back as far as possible.
Observe the instructions for correct use of
the child restraint system (Y page 66).For safety reasons, Mercedes-Benz recom-
mends that you only use a child restraint sys-
tem recommended by Mercedes-Benz
(Y page 70). 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.
You will find further information on stowing
objects, luggage and loads securely under
"Loading guidelines" (Y page 298). 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 58

and be thrown around, endangering vehicle
occupants. This poses an increased risk of
injury or even fatal injury.
Fit the ICS padded play table as described.
After fitting the ICS padded play table, make
sure that it is secured correctly. For safety
reasons, only use the ICS padded play table
that has been tested and approved for your
vehicle.
The ICS padded play table is only suitable for
use with the folded-out integrated child seat.
On the rear seats with an integrated child
seat, only use the ICS padded play table that
is recommended for Mercedes-Benz vehicles. Only use the ICS padded play table with its
original cover. Without the original cover, the
official approval is invalidated.
Use the ICS padded play table in accordance
with the instructions in the table in the "Inte-
grated child seat (ICS)" section (Y page 61).
Note that children under two years old and
children who weigh less than 12.5 kg require a different and suitable child restraint system.
Information about other child restraint sys-
tems is available at any Mercedes-Benz Ser-
vice Centre.
You must not use the integrated child seat
with ICS padded play table as a direct attach- ment to a baby car seat for which a body
weight of up to 10 kg is permissible. Note that
children younger than 24 month sold require
a different child restraint system
(Y page 70).
If you are not using the ICS padded play table, stow it in an appropriate place, e.g. in the lug-
gage compartment. You will find further infor-
mation on stowing objects, luggage and loads securely under "Loading guidelines". Fitting the ICS padded play table
