aint syst em in an accident
em in an accident How
there straint system works depends on the
se verity of the impact de tected and the apparent
type of accident:
R Frontal impact
R Rear impact
R Side impact
R Rollover
The activation thre sholds forth e components of
th ere straint system are de term ined based on the
ev aluation of the sensor values measured at vari-
ous points in theve hicle. This process is pre-e mp-
tive in nature. The triggering/deployment of the
components of there straint system must take
place in good time at the start of the collision.
Fa ctors which can only be seen and measured
aTer a collision has occur red cannot play a deci-
sive role in airbag deployment. Nor do they pro-
vide an indication of airbag deployment.
The vehicle may be deformed signi/cantly without
an airbag being depl oyed. This is the case if only
parts which are relatively easily deformed are
a.ec tedand thera te of vehicle deceleration is 46 46

Depending on the accident situation, the post-col-
lision brake can minimise the se verity of a fur ther
collision or even avo id it. If an accident is de
tected, the post-collision brake
can implement automatic braking. When theve hi-
cle has come toa standstill, the electric parking
brake is automatically applied.
The driver can cancel automatic braking bytaking
th efo llowing actions:
R braking more strongly than automatic braking

R The child restraint system must be appropria te
to the age, weight and size of thech ild.
R The vehicle seat must be suitable for /tting a
ch ild restraint system (/ page 70).
Ac cident statistics show that children secured on
th ere ar seats are generally safe rth an children
secured on the front seats. Forth is reason,
Mercedes-Benz st rongly advises that you /t a
