aint syst em in an accident
em in an accident How
there straint system 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 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 do not play a deci-
sive role in the deployment of an airbag. Nor do
th ey prov ide 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
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. 44

R road users with poor lighting, e.g. cyclists
R road users whose lighting is obstructed,
e.g. bya bar rier
On very rare occasions, Adaptive Highbeam
Assist Plus may failto recognise other road
users with their own lighting, or may recognise
th em too late.
In these, or in similar situations, the automatic
high beam will not be deactivated or will be
activated despite the presence of other road
users. #
Always obser vethero ad and tra1c con-
ditions carefully and switch o. the high
beam in good time. Ad
aptive Highbeam Assist Plus cann ottake into

De tection may be restric ted in thefo llowing
cases:
R in poor visibility, e.g. fog, heavy rain or snow
R ifth ere is dirt on the sensors or the sensors
