Rif, on vehicles with DISTRONIC PLUS,the
radar sensor system detectsanimminent
dangerofcollision in certain situations.
Rin critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely.
PRE-SAFE®takes the following measures
depending on the hazardous situation
detected:
Rthe front seat belts are pre-tensioned.
Rthe front-passenger seat is adjusted if it is
in an unfavorable position.
Rvehicles withamulticontour seat or active
multicontour seat: the air pressure in the
side bolsters of the seat cushion and
backrest is increased.
Rif the vehicle skids, the sliding sunroof and
the side windows are closed so that only a
small gap remains.
If the hazardous situation passes without
resulting in an accident,PRE-SAFE®slackens
the belt pre-tensioning. The air pressure in
the side bolsters on the multicontour seat/
active multicontour seat is reduced again. All
settings made by PRE-SAFE®can then be
reversed.
If the seat belts are not released:
XWhen the vehicle is stationary, move the
backrest or seat back slightly.
The seat belt pre-tensioningisreduced and
the lockingmechanism is released.
Information about seat belt adjustment, a
conveniencefunction integrated into PRE-
SAFE®,can be found in the "Seat belt
adjustment" section (Ypage 57).
Seat belts
Important safety notes
GWARNING
The seat belt does not offer the intended level
of protection if the backrest is not in the
upright position. When braking or in the event
of an accident,you could slide underneath the
seat belt and sustain abdomen or neck
injuries, for example. This poses an increased
risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always make sure that the seat
is in the upright position.
GWARNING
Seat belts cannot protect as intended, if:
Rthey are damaged, extremely dirty,
bleached or dyed
Rthe seat belt buckle is damaged or
extremely dirty
Rthe Emergency TensioningDevices or the
belt anchorage has been modified.
Damage caused to seat belts in an accident
may not be visible, e.g. by splinters of glass.
Modified or damaged seat belts can tear or
fail, for example in the event of an accident.
Modified Emergency TensioningDevices may
be deployed unintentionally or fail to be
deployed when required. There is an
increased risk of injury, possibly even fatal.
Never modify seat belts, Emergency
TensioningDevices, seat belt anchorages and
inertia reels. Ensure that seat belts are not
damaged or worn and are clean.
Only use seat belts that have been approved
for your vehicle by Mercedes-Benz.
The use of seat belts and infant and child
restraint systems is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadianprovinces
Even where this is not required by law,all
vehicleoccupants should correctly fasten
their seat belts before starting the journey.
iSee "Children in the vehicle"
(Ypage60) for further information on
infants and children traveling in the vehicle
