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 224).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. The securing systems of child restraint systems
are:
R the seat belt system
R the ISOFIX or i-Size securing rings
R the Top Tether anchorages
If it is absolutely necessary to fit a child restraint system to the front-passenger seat, always
observe the information on "Child restraint sys-
tems on the front-passenger seat"
(Y page 52).
Observe the warning labels in the vehicle inte-
rior and on the child restraint system.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems rec- ommended by Mercedes-Benz. You can
obtain information about this at any
Mercedes-Benz Service Centre. ISOFIX and i-Size child restraint sys-
tems
G
WARNING
ISOFIX child restraint systems or i-Size child
restraint systems do not offer sufficient pro-
tection for children whose weight is greater
than 22 kg, who are secured using 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 or i-Size 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.
When fitting a child restraint system, be sure to
observe the manufacturer's installation and
operating instructions and the instructions for
correct use of the child restraint system
(Y page 54).
Before every trip, make sure that the ISOFIX
child restraint system is engaged correctly in
both ISOFIX securing rings. 50

dent, heavy braking or sudden changes of
direction. As a result, child restraint systems
cannot perform their intended protective
function. Rear seat backrests that are not
locked can also cause additional injuries, e.g. in the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always lock rear seat backrests after fitting a Top Tether belt. Observe the lock verificationindicator. Adjust the rear seat backrests so
that they are in an upright position.

passenger seat
General notes Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install a child restraint system on a rear seat.
Vehicles with the automatic front-passenger
front airbag deactivation system: if it is abso-
lutely necessary to fit a child restraint system tothe front-passenger seat, always observe the
information on the "Automatic front-passenger
front airbag deactivation system" (Y page 42).52
Children in the vehicleSafety
Forward-facing child restraint system
If it is absolutely necessary to fit a forward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible. Fully
retract the seat cushion length. The entire base of the child restraint system must always rest on
the seat cushion of the front-passenger seat.
The backrest of the child restraint system must, as far as possible, lie flat against the backrest of
the front-passenger seat. The child restraint sys- tem must not touch the roof or be put under
strain by the head restraint. Adjust the angle of
the seat backrest and the head restraint posi-
tion accordingly. Always make sure that the
shoulder belt strap is correctly routed from the
vehicle belt outlet to the shoulder belt guide on the child restraint system. The shoulder belt
strap must be routed forwards and downwards
from the vehicle belt outlet. If necessary, adjust
the vehicle belt outlet and the front-passenger
seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
(Y page 54) in addition to the child restraint
system manufacturer's installation and operat-
ing instructions. Suitable positioning of the child
restraint system
Introduction Only child restraint systems approved in accord-
ance with the ECE standards ECE R44 or ECE
R129 (i-Size child restraint systems) are permit- ted for use in the vehicle.
For certain child restraint systems in weight cat-egories II or III, this can mean that the area of
use is restricted. The maximum size setting of
the child restraint system is not possible due to
possible contact with the roof.
"Universal" category child restraint systems can be recognised by their orange approval label and
the text "Universal" or an "i-Size" label. Example: approval labels on the child restraint
system
ISOFIX or i-Size child restraint systems of the
“Universal“ category can be used on seats label-
led U, UF, IUF or i-U in accordance with the fol-
lowing tables:
R Suitability of the seats for attaching belt-
secured child restraint systems
R Suitability of the seats for attaching ISOFIX
child restraint systems
R Suitability of the seats for attaching an i-Size
child restraint system.
Semi-universal child restraint systems are indi-
cated by the text "semi-universal" on the
approval label. These can be used if the vehicle and the seat are listed in the child restraint sys-
tem manufacturer's vehicle model list. For more
information, contact the child restraint system
manufacturer or visit their website.
Child restraint system on the front-
passenger seat – if it is absolutely necessary to
secure a child in a child restraint system on the front-passenger seat:
X Always pay attention to the instructions under
"Child restraint system on the front-
passenger seat" (Y page 52).
There you will find instructions on how to cor- rectly route the shoulder belt strap from the 54
Children in the vehicleSafety
vehicle belt outlet to the shoulder belt guide
on the child restraint system (Y
page 54).
X Move the front-passenger seat as far back as
possible and fully retract the seat cushion
length.
If you secure a child in a forward-facing child
restraint system on the front-passenger seat,
you must also move the front-passenger seat to the highest position.
X Move the backrest to an almost vertical posi-
tion.
The entire base of the child restraint system
must always rest on the seat cushion of the
front-passenger seat. The backrest of the
forward-facing child restraint system must, as far as possible, be resting on the backrest of
the front-passenger seat. The child restraint
system must not touch the roof or be put
under strain by the head restraint. Adjust the angle of the seat backrest and the head
restraint position accordingly. Also observe
the child restraint system manufacturer's
installation instructions.
X If possible, move the seat cushion angle to the
highest, most vertical position (Y page 88). Children in the vehicle
55Safety Z
Suitability of the seats for attaching a belt-secured child restraint system
If you use a baby car seat of category 0 or 0+ or a rearward-facing child restraint system of category
I on a rear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch
the child restraint system.
If you use a category I, forward-facing child restraint system, you should remove the head restraint of the respective seat (Y page 90), if possible. The backrest of the child restraint system must, as
far as possible, lie flat against the backrest of the seat.
Always observe the notes in the "Child restraint system" section (Y page 49) and the child restraint
system manufacturer's installation instructions.
When you remove the child restraint system you must replace the head restraints again immediately (Y page 89). All vehicle occupants must adjust their head restraints correctly before beginning the
journey.
