aries depending

er behaviour and the traffic situation.
Advance warning
If the system detects a possible collision with
the vehicle in front, it may alert the driver by
means of an audible warning and an indica-
tion on the instrument panel display
›››
Fig. 231.
The warning moment varies depending on
the traffic situation and driver behaviour. At
the same time, the vehicle will prepare for a
possible emergency braking

.
Critical w
arning
If the driv
er f
ails to react to the pre-warning
(advance warning), the system may actively
intervene in the brakes and generate a brief
jolt to warn the driver of the imminent danger
of a collision.
Automatic braking
If the driver also fails to react to the critical
warning, the system may initiate independent
emergency braking by progressively increas-
ing the braking effect in accordance with how
critical the situation is.
Driver emergency braking assistance sys-
tem
Faced with an imminent collision, the system
may detect that the driver is not braking hard
enough to avoid the collision. In this case, it
will automatically increase the braking effect.
Due to certain driving circumstances and the
limitations of its operation, there are some
cases in which the system cannot prevent a
collision, although it can significantly mini-
mise the consequences by reducing the
speed and the force of the impact.

WARNING
The Front Assist system cannot change the
laws of physics or repl
ace the driver in
terms of keeping control of the vehicle and
reacting to a possible emergency situation.
WARNING
Following a Front Assist emergency warn-
ing, pay immediate attention t
o the situa-
tion and try to avoid the collision by brak-
ing or by dodging the obstacle, as applica-
ble.
●
If the Front Assist does not work as de-
scribed in this chapter (e.g. it repeatedly
intervenes unnecessarily), switch it off.
●
Adapt your speed and safe distance t
o
the vehicle in front of you at all times to suit
visibility, weather, road and traffic condi-
tions.
●
The Front Assist alone cannot avoid acci-
dents and serious injuries.
●
In complex driving situations, occasional-
ly the Front Assist may issue warnings and
intervene in braking unnecessarily, for ex-
ample at traffic islands.
●
If the operation of the Front Assist is im-
paired, for example, by dirt or because the
radar sensor has lost its settings, the sys-
tem may issue unnecessary warnings and
intervene inopportunely in the braking.
●
The Front Assist does not react to animals
or vehicles crossing your path or ap-
proaching head-on down the same lane.
●
The Front Assist does not react to pedes-
trians walking head-on in the same lane.
●
The driver must always be ready to take
over the control of the vehicle.
Note
●
When the Front Assist is connected, the
indications on the instrument panel scr
een
may be concealed by warnings from other
functions, such as an incoming call.
●
When the Front Assist causes a braking,
the brake pedal is “harder”.

Automatic interventions by the Front As-
sist on the brakes may be interrupted by
