acti vated unintentionally or not deploy as
intended in an accident. #

traint syst
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 deplo yed. This is the case if only
parts which are relatively easily deformed are
a.ec tedand thera te of vehicle deceleration is
not high. Con versely, an airbag may be depl oyed
ev en though theve hicle su.ers only minor defor-
mation. If very rigid vehicle parts such as longitu-
dinal membe rsare hit, this may result in su1-
ciently high le vels of vehicle deceleration.
Depending on the de tected deployment situation,
th e components of there straint system can be
acti vated 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: frontal
impact
R Knee airbag: frontal impact
R Side airbag: side impact
R Window airbag: side impact, rollo ver,frontal

pants. These measures cannot necessarily pre-
ve nt an imminent impact.
PRE-SAFE ®
PLUS can implement thefo llowing
measures independently of each other:
R Tightening the seat belts on the driver's seat
and front passenger seat.
R Activating there ar hazard warning lights at a
higher 0ashing frequency.
R Increasing brake pressure when theve hicle is
stationar y.This brake application is cancelled
automatically when theve hicle pulls away.
If an accident did not occur, the pre-em ptive
measures that we re ta ken are reve rsed.

Depending on the type and se verity of the acci-

R activating the hazard warning lights
R triggering an automatic emer gency call

Depending on the accident situation, the post-col-

collision or evenavo 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
