Advance warning
If the system detects a possible collision with
the vehicle in front, it alerts the driver by
means of an audible warning and an indication
on the instrument panel display
The warning moment varies depending on the
traffic situation and driver behaviour. At the
same time, the vehicle will prepare for a possi-

When Front Assist is connected, the indica-

Critical warning
If the driver fails to react to the advance warn-
ing, 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 increasing
the braking in accordance with the criticality of
the situation.

assist only occurs if the pedal is pressed firmly.
WARNING
in Introduction
●
The system cannot prevent a collision, al-
though it can significantly minimise the con-
sequences 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 Assist
on the brakes may be interrupted by press-
ing the accelerator or moving the steering
wheel.
●
The Front Assist may brake the vehicle until
it stops completely. However, the brake sys-
tem does not halt the vehicle permanently.
Use the foot brake!
Pedestrian and cyclist recognition
The system recognises pedestrians and cyclists
who travel in the same lane and direction and
pedestrians and cyclists who transversely cross
the vehicle's path.
Assistant systems
Pedestrian and cyclist recognition technology
cannot exceed the physically prescribed limits
and works exclusively within the system's limits.
The responsibility for braking always 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 operat-
ing speed range is lower than that of the Front
Assist.
Dodge assist
Dodge assist helps the driver avoid an obstacle
in critical conditions.
Once the Front Assist has activated 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 system and
not an autonomous one.
The system is active between approximately
30 km/h (20 mph) and 150 km/h (90 mph).
