Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. This
function adjusts the driver's and front-
passenger seat belt to the upper body of the
occupants.
The belt strap is tightened slightly when:
R the seat belt tongue is engaged in the belt
buckle and
R the ignition is switched on
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the vehicle occupant and the seat
belt. Do not hold on to the seat belt tightly
while it is adjusting.
You can switch the seat-belt adjustment on
and off in the on-board computer
(Y page 249).

Function
PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
R on vehicles with DISTRONIC PLUS: if adap-
tive Brake Assist intervenes powerfully
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R if the vehicle skids, the side windows are
closed so that only a small gap remains.
The panorama sliding sunroof is completely
closed.
R vehicles with the memory function: the
front-passenger seat is adjusted if it is in an
unfavourable position.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pre-tensioning. All settings made by
PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back
slightly when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. Infor-
mation about the convenience function can
be found under "Belt adjustment"
(Y page 45). Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact: R the hazard warning lamps are activated
R the emergency lighting is activated R
the vehicle doors are unlocked
R the front side windows are lowered
R the engine is switched off and the fuel sup-
ply is cut off
R vehicles with the Mercedes-Benz emer-
gency call system: automatic emergency
call Children in the vehicle
Important safety 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. Children are generally better pro-
tected there.
If a child younger than 12 years old and under 1.50 m in height is travelling in the vehicle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child.
R be sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions.
R always pay attention to the instructions
and safety notes on the automatic front-
passenger front airbag deactivation system
(Y page 49). G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine Children in the vehicle

X Adjust the head restraint if necessary; see
(Y page 111).
Side head restraints G
WARNING
If the side head restraint has been fitted incor-
rectly, it cannot perform its intended protec-
tive function. A child's head therefore cannot be supported in the event of an accident,
heavy braking or a sudden change of direc-
tion. In addition, the side head restraint could become loose and be thrown around, endan-
gering vehicle occupants. This poses an
increased risk of injury or even fatal injury.
Only fasten the side head restraint to the spe-
cially designed securing points on the rear
head restraint. For safety reasons, only use
side head restraints that have been tested
and approved for your vehicle. Use the side head restraints in accordance
with the instructions in table (Y
page 61).
Fitting side head restraints
X Slide head restraint ;upwards and posi-
tion it upright.
X Slide side head restraints Bfrom the front
to the centre of both head restraint bars
until they engage.
Right lock verification indicator :and left
lock verification indicator =must be fol-
ded in. The red surfaces are no longer visi-
ble. X
Make sure that side head restraint Bis
engaged in both head restraint bars.
X Slide head restraint ;downwards
(Y page 111) until it rests on the upper
edge of side head restraints B.
X If the seat belt is not routed as described
(Y page 62), guide the seat belt through
seat belt guide Aon the door side on side
head restraint B.
This is not necessary when:
R using an ICS padded play table, or
R children older than 6 years old are
secured in an integrated child seat
X Secure the child (Y page 62).
Removing the side head restraints X Remove the seat belt from seat belt guide
A.
X Move head restraint ;upwards.
X Press left or right release button ?and pull
side head restraint Bforward to remove it.
Right lock verification indicator :and left
lock verification indicator =fold out
briefly.
X Adjust head restraint ;(Ypage 111).
X Stow the side head restraint in a suitable
place.
On vehicles with a TIREFIT kit, for example,
you can store the side head restraints in thestowage compartment under the luggage
compartment floor (Y page 308).
i Should a side head restraint be required
for the second integrated child seat, this
can be ordered at any Mercedes-Benz Deal- ership. 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 64
Children in the vehicleSafety

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 systemto the front-passenger seat, always observe
the information on the "Automatic front-
passenger front airbag deactivation system"
(Y page 49).
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 41).
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 66).
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 66). Children in the vehicle
