Driver assistance systems
Emergency brake assistance
syst em (Fr
ont Assist)*
Introduction The objective of the system is to prevent
head-on collisions against ob
jects that may
be in the v

ehicle’s path or minimise the con-
sequences of such impacts.
The function is designed to avoid collisions
against:

Driving
Advance warning
If the syst em det
ects a possible collision with
the vehicle in front, it alerts the driver by
means of an audible warning and an indica-
tion on the instrument panel display {
››› Fig. 176.
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 ››› in Intro-
duction on page 2 49

.
When Front Assist is connected, the indica-
tions of other functions on the screen may be
hidden.
Critical warning
If the driver fails to react to the 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 colli-
sion.
Automatic braking
If the driver also fails to react to the critical
warning, the system may initiate independ-
ent emergency braking by progressively in-
creasing the braking in accordance with the
criticality of the situation. Driver emergency braking assistance sys-
tem
If the driv

er, after the critical warning, starts
braking but the system detects that the brake
is not being applied with sufficient force, the
braking intensity will be increased. This brake
assist only occurs if the pedal is pressed firm-
ly. WARNING

Driver assistance systems
Limitations
This syst em does not r
eact to objects that
cross transversely or to animals. The basic
limitations of the Front Assist must also be
taken into account ››› page 251
.
Turn assist Turn assist can avoid a collision with a vehicle
appr
oaching in the opposit

e direction, by
braking the vehicle itself when the intention is
to turn.
This system is active up to 15 km/h (9 mph).
Limitations
The turn-off assist function is available if you
have indicated your intention to turn by acti-
vating the turn signal, you have turned the
steering wheel and the turning path has star-
ted.
It only reacts to vehicles that are in the path
of the vehicle (not to animals, people, etc.).
The basic limitations of the Front Assist must
also be taken into account ››› page 251

the syst
em. Thus, in cert

ain circumstances,
some of the reactions may be inappropriate
from the driver's standpoint. So pay attention
in order to intervene if necessary.
The following conditions may cause the
Front Assist not to react or to do so too
late:
