otection pr ovided bythere stra int sy stem The
restra int sy stem includes thefo llowing com‐
ponents:
R Seat belt sy stem
R Airbags
R Child restra int sy stem
R Child seat securing sy stems
The restra int sy stem can help pr eventtheve hi‐
cle occupants from coming into contact with
parts of theve hicle interior in theev ent of an
accident. In theev ent of an accident, the
re stra int sy stem can also reduce thefo rc es to
which theve hicle occupants are subjected.
A seat belt can only pr ovide the best le vel of pro‐
te ction if it is worncor rectl y.Depending on the
de tected accident situation, seat belt tensioners
and/or airbags supplement the pr otection
of fere dby a cor rectly wornseat belt. Seat belt
te nsioners and/or airbags are not depl oyed in
eve ryaccident. In order
forth ere stra int sy stem toprov ide the
intended le vel of pr otection, each vehicle occu‐
pant must obser vethefo llowing information:
R Fasten seat belts cor rectl y.
R Sit in an almost up right seat position with
th eir back against the seat backrest.
R Sit with their feet resting on thefloor, if pos‐
sible.
R Alw ays secure persons under 1.50 m tall in
an additional restra int sy stem suitable for
Mercedes-Benz vehicles.
Ho wever,no sy stem available today can com‐
ple tely elimin ate injuries and fata lities in every
accident situation. In particular, the seat belt
and airbag generally do not pr otect against
objects penetrating theve hicle from the outside.
It is also not possible tocompl etely rule out the
ri sk of injury caused bythe airbag deploying. Re

not light up when the ignition is switched on
R the6 restra int sy stem warning lamp

WARNING Risk of inju rydue tomalfunc‐
tions in there stra int sy stem
Components in there stra int sy stem may be
activated unintentionally or not deploy as
intended in an accident. #
Have there stra int sy stem checked and
re paired immediately at a qualified spe‐
cialist workshop. Fu
nction of there stra int sy stem in an acci‐
dent How
there stra int sy stem works is de term ined by
th e se verity of the impact de tected and the type
of accident anticipated:
R Frontal impact
R Rear impact
R Side impact
R Rollover
The activation thre sholds forth e components of
th ere stra int sy stem are de term ined based on
th eev aluation of the sensor values measured at
va rious points in theve hicle. This process is pre-
em ptive in nature. The triggering/deployment of
th e components of there stra int sy stem must
ta ke place in good time at thest art of the colli‐
sion.
Fa ctors whi chcan only be seen and measu red
af te r a collision has occur red do not play a deci‐
sive role in the deployment of an airbag. Nordo
th ey prov ide an indication of airbag deployment.
The vehicle may be deformed significantly with‐
out an airbag being deplo yed. This is the case if only parts which are
relatively easily deformed
are af fected and thera te ofvehicle deceleration
is not high. Con versely, an airbag may be
deplo yedev en though theve hicle suf fers only
minor deformation. If very rigid vehicle parts
such as longitudinal members are hit, this may
re sult in suf ficiently high le vels of vehicle decel‐
eration.
Depending on the de tected deployment situa‐
tion, the components of there stra int sy stem can
be activated or deplo yed independently of each
ot her:
R Seat belt tensioner: frontal impact, rear
impact, side impact, rollo ver
R Driver's airbag, front passenger airbag: fron‐
talimpact
R Knee airbag: frontal impact
R Side airbag: side impact
R Head airbag: side impact, rollo ver,frontal
