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 or loads under "Loading
guidelines" . 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.
If it is absolutely necessary to carry a child on the front-passenger seat, be sure to observe
the information on "Child restraint systems
on the front-passenger seat" (Y page 63).
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
recommended by Mercedes-Benz. You can obtain information about this at any
Mercedes-Benz Service Centre. ISOFIX child seat securing system
G
WARNING
ISOFIX child restraint systems do not offer
sufficient protective effect for children whose weight is greater than 22 kg who are securedusing 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 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 instruc-
tions for correct use of the child restraint sys- tem (Y page 64).
Before every trip, make sure that the ISOFIX
child restraint system is engaged correctly in both ISOFIX securing rings.
! 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 securing rings
X Install the ISOFIX child restraint system on
both ISOFIX securing rings :.
ISOFIX is a standardised securing system for
specially designed child restraint systems on
the rear seats. ISOFIX securing rings :for
two ISOFIX child restraint systems are fitted
on the left and right of the rear seats.
Secure child restraint systems without an
ISOFIX child seat securing system using the
seat belts in the vehicle. When fitting a child
restraint system, be sure to observe the man-
ufacturer's installation and operating instruc-
tions and the instructions for correct use of
the child restraint system (Y page 64). Children in the vehicle

Top Tether
Introduction Top Tether provides an additional connection
between the child restraint system secured
with ISOFIX and the rear seat. It helps reduce
the risk of injury even further. If the child
restraint system is fitted with a Top Tether
belt, this should always be used.
Important safety notes G
WARNING
If the rear seat backrests are not locked, they
could fold forwards in the event of an acci-
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.
Top Tether anchorages The Top Tether anchorages are located on the
rear side of both outer rear seat backrests. Vehicles with adjustable head restraints:
X Top Tether belt with one belt strap: push
head restraint :upwards.
X Route Top Tether belt ?under head
restraint :between the two head restraint
bars.
or
X Top Tether belt with two belt straps:
route each Top Tether belt ?on the left
and right past the side of head restraint :.
Vehicles without adjustable head
restraints: X Top Tether belt with one belt strap: route
Top Tether belt ?centrally over head
restraint :.
or
X Top Tether belt with two belt straps:
route each Top Tether belt ?on the left
and right past the side of head restraint :.
All vehicles:
X Fit the ISOFIX child restraint system with
Top Tether. Always comply with the child
restraint system manufacturer's installa-
tion instructions when doing so.
X Hook Top Tether hook =of Top Tether
belt ?into Top Tether anchorage ;.
Ensure that:
R Top Tether hook =is hooked into Top
Tether anchorage ;as shown.
R Top Tether belt ?is not twisted.
R Top Tether belt ?is routed between the

front-passenger seat to the highest posi-
tion.
X Move the backrest to an almost vertical
position.
The bottom and back of a forward-facing
child restraint system must make full con-
tact with the front-passenger seat cushion
and backrest. The child restraint system
must not touch the roof. Adjust the back-
rest angle accordingly. Also observe the
child restraint system manufacturer's
installation instructions.
X For seats with electrical adjustment, the
seat cushion angle must be set to the high-
est and most upright position.
For certain child restraint systems in
weight category 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". Example: approval label on the child restraint sys-
tem
"Universal" category child restraint systems
can be used on the seats indicated with U, UF
or IUF according to the tables "Suitability of
the seats for attaching belted child restraint
systems" or "Suitability of the seats for
attaching an ISOFIX child restraint system".
Semi-universal child restraint systems are
indicated by the text "Semi-universal" on the
approval label. These can be used if the vehi- cle and the seat are listed in the child restraint
system manufacturer's vehicle model list. For
more information, contact the child restraint
system manufacturer or visit their website. Children in the vehicle
