The system checks for visual impairments. De-
pending on the vehicle equipment, the Driver
Attention Camera in the instrument cluster
captures the driver’s field of vision. Visibility
and field of vision also affect the timing of the
warnings.
Display in the instrument cluster
The following indicator/warning lights are
shown on the instrument cluster and, depend-
ing on vehicle equipment, on the Head-up dis-
play:
Icon Meaning
Risk of collision with a person, e.g., a
pedestrian.
Risk of collision, for instance with an
oncoming or a vehicle driving ahead.
Risk of collision, e.g., with a vehicle
crossing from the right.
Risk of collision, e.g., with a vehicle
crossing from the left.
General risk of collision.
The corresponding indicator lights and warn-
ing lights may display differently if the system
detects multiple objects.
Warning function
The Forward Collision Mitigation warns on dif-
ferent warning levels, depending on the re-
spective hazardous situation.
In the event of a prewarning, a warning light
illuminates red. In the event of an acute warn-
ing, a warning light flashes red and a warning
tone sounds.
In the event of a system warning, the driver
must intervene immediately and in accordance
with the situation.
▷
Red warning light illuminates:
A hazardous situation has been detected.
Increased awareness is required.
▷ Red warning light flashes:
There is a risk of collision. Intervene imme-
diately.
▷ A warning signal sounds:
There is a risk of collision. Intervene imme-
diately.
▷ Automatic brake intervention:
Depending on the equipment and situation
in case of risk of imminent collision, the
system can also intervene with an auto-
matic brake intervention and automatically
decelerate the vehicle, if necessary, to a
complete stop.
When the brake pedal is depressed quickly and
hard, the maximum brake power of the vehicle
is used.
Automatic brake intervention
In case of a risk of collision, the system can
assist with an automatic brake intervention, if
necessary.
When the vehicle is traveling at a low speed,
the vehicle may come to a complete stop.
During automatic brake intervention, Dynamic
Stability Control activates automatically.
A brake intervention can be canceled by de-
pressing the accelerator pedal with sufficient
force, releasing the brake pedal, or by actively
steering.
Depending on the equipment and situation,
the brake intervention can occur up to approx.
155 mph/250 km/h.
At speeds above approx. 130 mph/210 km/h,
only a brief brake intervention will occur.
