Introduction Top Tether provides an additional connection
between the child restraint system secured
with ISOFIX and the vehicle. 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.
If the rear backrest is not engaged and
locked, the red lock verification indicator will be visible (Y page 319).62

down again slightly (Y page 116). 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 the "Automatic front-
passenger front airbag deactivation system"
(Y page 51). Children in the vehicle

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. G
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). 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.
If you turn the key to position 2in the ignition
lock, the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
light up briefly. However, they have no func-
tion and do not indicate that there is an auto- matic front-passenger front airbag deactiva-
tion system.
Always fit the rearward-facing restraint sys-
tem to a suitable rear seat in this case
(Y page 65).
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 65).
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 64

lamp is lit continuously (Y
page 43)is the
front-passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 65) 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. 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 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. Always make sure that the shoul-
der 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 down- wards from the vehicle belt outlet. If neces-
sary, 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 65) 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 approved in
accordance with the ECE standards ECE R44
or ECE R129 (i-Size child restraint systems)
are permitted for use in the vehicle. For certain child restraint systems in weight
categories 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
labelled U, UF, IUF or i-U in accordance with
the following 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
