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

X Tension Top Tether belt ?. Always comply
with the child restraint system manufactur-
er's installation instructions when doing so.
Vehicles with adjustable head restraints: X If necessary, move head restraint :back
down again slightly (Y page 112). Make
sure that you do not interfere with the cor-
rect routing of Top Tether belt ?.Child restraint system on the front-
passenger seat
General notes Accident statistics show that children
secured in the rear seats are safer than chil-
dren 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
to the front-passenger seat, always observe
the information on "Automatic front-
passenger front airbag deactivation system"
(Y page 51).
You can thus avoid the risks that could arise
as a result of:
R a child restraint system that is not detected
by the automatic front-passenger front air- bag deactivation system
R the unintentional disabling of the front-
passenger front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board Please observe the warning notice on the
front-passenger sun visor, see the illustra-
tion.

WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The childcould be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
NEVER use a rearward facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it, DEATH or SERIOUS INJURY to the
CHILD can occur.
If the PASSENGER AIR BAG ON indicator lamp
is lit, the front-passenger front airbag is ena-
bled (Y page 43). Children in the vehicle

Vehicles without the automatic front-
passenger front airbag deactivation
system If the front-passenger seat of your vehicle is
not equipped with the automatic front-
passenger front airbag deactivation system,
this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. The sticker is
visible when you open the front-passenger
door.
In this case, always fit the rearward-facing
child restraint system to a suitable rear seat
(Y page 64).
Observe the following information under
"Rearward-facing child restraint system" and
"Forward-facing child restraint system" as
well as information on the suitable position-
ing of the child restraint system
(Y page 64).
Rearward-facing child restraint system If it is absolutely necessary to fit a rearward-
facing child restraint system to the front-
passenger seat, always make sure that the
front-passenger front airbag is disabled. Only if the PASSENGER AIR BAG OFF indicator
lamp is permanently lit (Y page 43) is the
front-passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 64) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions. 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.
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 64) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions. Suitable positioning of the child
restraint system
Introduction Only child restraint systems which are
approved in accordance with the ECE stand-
ard ECE R44 are permitted for use in the vehi- cle.
Child restraint system on the front-
passenger seat – if it is absolutely necessary
to fit a child restraint system to the front-
passenger seat:
X Always pay attention to the instructions
under "Child restraint system on the front-
passenger seat" (Y page 63).
There you will find instructions on how to
correctly route the shoulder belt strap from the vehicle belt outlet to the shoulder belt
guide on the child restraint system
(Y page 64).
X 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, you must also move the 64

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
