PRE-SAFE ®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R if BAS activates, e.g. in emergency braking
situations
R if BAS PLUS intervenes powerfull y—on
vehicles wit hDISTRONIC PLUS
R if, on vehicles with DISTRONIC PLUS, the
radar sensor system detects an imminent
dang er of collision in cer tain situations
R in critical drivin gsituations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R vehicles with the memor yfunction: the
front-passenger seat is adjusted if it is in an
unfavourable position.
R vehicles with amulticontour seat: the air
pressure in the side bolsters of the back-
rest is increased.
R if the vehicle skids ,the slidin gsunroof/
panorama sliding sunroof and the side win-
dows are closed so that only asmall gap
remains.
If th ehazardous situation passe swithout
resulting in an accident ,PRE-SAFE ®
slackens
the belt pretensioning. On vehicles with mul-
ticontour seats ,the air pressur einthe side
bolster sisreduced again. All settings made
by PRE- SAFE®
can the nbereversed.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locki ng mech anism is released.

Important safety notes G
WARNING
As eat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, can notp rovide th eintended
level of protection. Under certain circumstan-
ces, this could cause severe or even fatal inju-
ries in the event of an accident.
Therefore, make sure that all occupants —in
particular ,pregnant women —wear their seat
belts cor rectly at all times.
R Th es eat belt must fit snugly on your body
and must not be twisted.Therefore, avoid
wearing bulky clothing, e.g. awinter coat.
The shoulder section of the belt must be
routed across the centre of your shoulder
—onnoa ccount acros syour nec korunder
your arm —and pulled tight against your
uppe rbody. The lap belt must always pass
across your lap as low down as possible, i.e.
over your hip join ts—n ot across your abdo-
men .Ifn ecessary, push the seat belt
slightly downwards and adjust it by pulling
it in the direction the seat belt retracts.
R Do not rout ethe seat belt strap over sharp
or fragile objec ts.P lease make sure that
such object sare not on or in your clothing,
e.g .spectacles, pens or keys etc. The seat
belt strap could become damaged and tear
durin gana ccident and you or other vehicle
occupants coul dbeinjured.
R Only one person should use each sea tbelt
at any one time. Children must never travel
sittin gont he lap of another occupan t.The
child will not be secured in the even tofan
accident ,heavy braking or sudden change
of direction .This ma yresult in the child or
other occupants being seriously or fatally
injured. 46
Occupant safetySafety

The seat belts on the following seats have belt
tensioner
sand bel tforc elimiters:
R driver's and front-passenger seat
R the outer seats in the second row
R the seats in the third row
The belt tensioners tighten the seat belts in
an accident ,pulling them close against the
body.
Belt tensioners do not correc tincorrect seat
positions or incorrectly fastened sea tbelts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fit tedw ithabelt force
limiter and this is triggered, the force exer ted
by the seat belt on the vehicle occupant is
reduced.
The belt force limiters for the fron tseats are
synchronised with the fron tairbags, which
tak eona part of the deceleration force. This
result sinthe force exerted on the occupant
being distributed over agrea tera rea.
Th eb elt tensioners can only be activa ted
when:
R the ignition is switched on.
R the restraint system sare opera tional; see
"SR Swarnin glamp" (Y page 41).
The belt tensioners on the outside seats in the
second row and on the seats in the thir drow
ar et riggere dindependently of the lock status
of the sea tbelts.
The belt tensioners are triggere ddepending
on the type and severity of an accident:
R if, in the even tofahead-on or rear-end col-
lision, the vehicle decelerates or acceler-
ates rapidly in alongitudinal direction dur-
ing the initial stages of the impact
R if, in the even tofaside impact, on the side
opposit ethe impac tthe vehicle deceler-
ates or accelerates rapidly in alateral direc-
tion
R in certain situations where the vehicle over-
turns and the system determines that it can
provide additional protection If the airbags are deplo
yed,you will hear a
bang, and asmall amount of powder may also
be released. Only in rare cases will th ebang
affect your hearing. The powde rthat is
released generally does not constitute a
healt hhazard. The 6SRS warning lamp

Child restraint systems
Important safety notes G
WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of asudden
change in direction, braking or an accident:
R children less than 1.50 mtall and under
twelve years of age must always be secured
in special child restraint systems on asuit-
able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R Do not drive with achild secured in arear-
ward-facing child restraint system on the
front-passenger seat. Exception: if the vehi-
cle is equipped with automatic child seat
recognition on the front-passenger seat
and the child is secured in achild restraint
system with transponders for automatic
chil dseat recognition
R if you secur eaforward-facing child
restraint system to the front-passenger
seat, you must mov ethe front-passenger
seat as fa rback as possible.
R children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of asudden
change of direction, heavy braking or an
accident, it would not be possible to
restrain the child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured. 50

WARNING
If the 4 PASSENGE RAIRBA GO FF indica-
tor lamp does not light up whe nthe child
restraint system is fitted, the fr ont-passenger
airbag has not been disabled. If the fr ont-
pa ssenger airbag deploys, the chil dcould be
seriou slyor even fatally injured.
Proceed as follows:
R do not use arearward-facin gchild restraint
system on the fr ont-passengers eat.
R fit arearward-facing child restraint system
on asuitable rear seat.
or R
only use aforward-facing child rest raint
system on the front-passenger seat and
move the front-passenger seat to the rear-
most position.
R have the automatic child seat recognition
checked at aqualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. acushion, under the child
restraint system. The entire base of the child
restraint system must alway srest on the seat
cushion. An incorrec tlyf itted child restraint
system cannot perfor mits intended protec-
tive function in the event of an accident, and
could lead to injuries. G
WARNING
Do not place electronic devices on the front-
passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes or
access cards
Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. Thi scan lead to a
system malfunc tion. This may cause the
4 PASSENGER AIRBA GOFF indicator
lamp to light up without there being achild
seat with transponder sfor automatic child
seat recognition fit ted. The front-passenger
airba gwill not then deploy during an accident.
It is also possible that the 6SRS warning
lamp lights up and/or the 4PASSENGER

briefly when you tur nthe key in the ignition
lock to position 2.52
