Child restraint system on the front-
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 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 airbag
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 illustration. 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 enabled
(Y page 44).
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 indica-
ted 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 function and
do not indicate that there is an automatic front- passenger front airbag deactivation system.
In this case, never fit a rearward-facing child
restraint system on the front passenger seat
(Y page 63).
Observe the following information under "Rear-
ward-facing child restraint system" and
"Forward-facing child restraint system" as well
as information on the suitable positioning of the
child restraint system (Y page 63).62
Children in the vehicleSafety

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
lit continuously (Y page 44)is the front-
passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 63) in addition to the child restraint
system manufacturer's installation and operat-
ing 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. 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 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 out-
let and the front-passenger seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
(Y page 63) 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 which are approved
in accordance with the ECE standard ECE R44
are permitted for use in the vehicle.
"Universal" category child restraint systems can
be recognised by their orange approval label and the text "Universal". Approval labels for child restraint systems in
accordance with ECE-R44 standards
"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 belt-secured child restraint sys-
tems" or "Suitability of the seats for attaching an
ISOFIX 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 62).
There you will find instructions on how to cor- rectly route the shoulder belt strap from the
vehicle belt outlet to the shoulder belt guide
on the child restraint system (Y page 63).
X Move the front-passenger seat as far back as
possible.
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 Children in the vehicle

Suitability of the seats for attaching belt-secured child restraint systems
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 from the respective seat, if possible (Y page 109). The backrest of the child restraint system must,
as far as possible, lie flat against the backrest of the seat.
Make sure that the child's feet are not touching the front seat. If necessary, move the front seat
forward slightly (Y page 109).
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.
Always observe the notes in the "Child restraint system" section (Y page 59) 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 109). All vehicle occupants must adjust their head restraints correctly before beginning the
journey.
