Assistant systems
Advance warning
If the s
y
stem detects 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. 153.
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

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 driver, 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 firmly.
WARNING
●
The system cannot prevent a collision, al-
though it can significantly minimise the
consequences by reducing the speed and
the force of the impact.
●
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
pressing the accelerator or moving the
steering wheel.
●
The Front Assist may brake the vehicle
until it stops completely. However, the
brake system does not halt the vehicle per-
manently. Use the foot brake!
Pedestrian and cyclist recognition
The system recognises pedestrians and cy-
clists who tr
a
vel in the same lane and direc-
tion and pedestrians and cyclists who trans-
versely cross the vehicle's path.
Pedestrian and cyclist recognition technolo-
gy cannot exceed the physically prescribed
limits and works exclusively within the sys-
tem’s limits. The responsibility for braking al-
ways depends on the driver.
The pedestrian and cyclist recognition can
cause undesired warnings and braking inter-
ventions, e.g. with a hidden radar sensor or a
dirty camera field of vision.
Be ready to take charge of the vehicle at any
time.
The pedestrian and cyclist recognition oper-
ating speed range is lower than that of the
Front Assist.
Dodge assist
Dodge assist helps the driver avoid an obsta-
cle in critical conditions.
Once the Fr
ont Assist has activ
ated a critical
warning, if the driver intends on dodging the
object, the dodge assist will help correct the
trajectory. The driver must start and finish
the manoeuvre, as this is an assistance sys-
tem and not an autonomous one.
Front Assist is active between approx. 30
km/h (20 mph) and 150 km/h (90 mph).
