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 depends on the
se verity of the impact de tected and the apparent
type of acciden t:
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 cann otplay a deci‐
sive role in airbag deployment. Nor do they pro‐
vide 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

tomatic measures af ter an accident
Depending on the type and se verity of the acci‐
dent, and depending on theve hicle's equipment,
th efo llowing measures can be implemen ted, for
ex ample:
R automatic braking (post-collision brake)
R activating the hazard warning lights
R triggering an automatic emer gency call
(/ page 334)
R switching off the engine
To restart theve hicle, switch the ignition off
and switch it back on (/ page189).
Depending on the type and se verity of the
accident, it is possible that theve hicle can
no longer be star ted. R
switching off the fuel supply
R unlocking theve hicle doors
R lowe ring the side windo ws
R displaying the emer gency guide in the cent ral
display
R switching on the interior lighting
Fu nction of the post-collision brake
Depending on the accident situation, the post-
collision brake can minimise the se verity of a fur‐
th er collision or evenavo id it.
If an accident is de tected, the post-collision
brake can implement automatic braking. When
th eve hicle has come toast andstill, the electric
parking brake is automatically applied.
The driver can cancel automatic braking bytak‐
ing thefo llowing actions:
R braking more stronglythan automatic brak‐
