Intersection Collision Warning with city

Safety information
Detection capability
The system's detection capability is limited.
Warning
The system only takes into account objects
that are located in the detection range of the
installed sensors and are detected by the sys-
tem.
The system cannot serve as a substitute for
the driver’s personal judgment in assessing
the traffic situation. Based on the limits of
the system, it cannot independently react to
all traffic situations. There is a risk of acci-
dent, injury, and property damage. Adjust
driving style to traffic conditions. Watch the
surrounding traffic situation closely, be ready
to take over steering and braking at any time,
and actively intervene where appropriate.
Depending on the vehicle equipment, the area
is monitored by cameras or radar sensors.
Thus, a system response might not come or
might come late.

Sensors of the vehicle, refer to page 41.
Warning
Indicators and warnings cannot serve as a
substitute for the driver’s personal judgment.
Due to its limits, the system may not issue
warnings or responses, or these may be is-
sued late or in a manner that is not consis-
tent with their normal use. There is a risk of
accident, injury, and property damage. Adjust
driving style to traffic conditions. Watch sur-
rounding traffic closely and actively intervene
where appropriate
Forward Collision Mitigation
with brake intervention
Principle
The Forward Collision Mitigation can help
prevent accidents. If an accident cannot be
avoided, the system can help reduce the se-
verity of the accident.
The system can issue a warning of a possible
risk of collision and activate the brakes inde-
pendently, if needed.
Sensors
Depending on the equipment, the system is
controlled by the following sensors:
General information
Depending on the equipment version, the For-
ward Collision Mitigation system includes the
following functions:
▷
▷
▷
Camera behind the windshield.
Front radar sensor.
Radar sensors, side, front.
▷
Forward Collision Warning with braking
function, refer to page 177.

Speed range
The system issues a warning of a possi-
ble risk of collision at speeds above approx.
3 mph/5 km/h.
Setting the warning time
1.
Apps menu
2. "Vehicle"
3. "Driving settings"
If the vehicle speed exceeds approx.
155 mph/250 km/h, the system is deactivated
temporarily.
4. "Driver Assistance"
5. "Safety and warnings"
6. "Forward Collision Mitigation"
7. Select the desired setting.
Some functions are deactivated earlier.
The system is enabled as soon as the speed
drops below these values again.
The more sensitive the warning time is set to
be, the more warnings will be displayed. The
system can therefore also issue more early or
unfounded warnings and reactions.
Turning the Forward Collision
Mitigation on/off
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.
Turning on the system automatically
Depending on the national-market version, the
system is automatically active after every de-
parture.
Turning on system manually
The system is activated by setting the warning
time.
Display in the instrument cluster
The following indicator lights and warning
lights are shown on the instrument cluster and,
depending on vehicle equipment, on the Head-
up display:

Setting the warning time, refer to page 175.

Risk of collision with a person, e.g., a
pedestrian.
Depending on national-market version, the ad-

at a standstill or in a very low speed range.
Risk of collision, for instance with a
preceding vehicle.
If necessary, the switch-off must be confirmed
successively on the control display.

Safety
CONTROLS
The corresponding indicator lights and warn-
ing lights may display differently if the system
detects multiple objects.
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.
Warning function
The Forward Collision Mitigation warns on dif-
ferent warning levels, depending on the re-
spective hazardous situation.
City brake function: the brake intervention oc-
curs to up to approx. 50 mph/80 km/h.
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.
With radar sensor: the brake intervention oc-
curs to up to approx. 155 mph/250 km/h.
At speeds above approx. 130 mph/210 km/h,
only a brief brake intervention will occur.
In the event of a system warning, the driver
must intervene immediately and in accordance
with the situation.

Because of system limitations, this system
may either not respond, or respond too late,
incorrectly, or without cause. There is a risk
of accident, injury, and property damage. Ac-
tively intervene as warranted. Refer to the in-
formation in this Owner’s Manual regarding
the scope of the system’s operation and limi-
tations.
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.
Detection capability
The system's detection capability is limited.
The system only takes into account objects
that are located in the detection range of the
installed sensors and are detected by the sys-
tem.
When the brake pedal is depressed quickly and
hard, the maximum brake power of the vehicle
is used.
Depending on the vehicle equipment, the area
is monitored by cameras or radar sensors.
Automatic brake intervention
In case of a risk of collision, the system can
assist with an automatic brake intervention, if
necessary.
Thus, a system response might not come or
might come late.

Additional information:
When the vehicle is traveling at a low speed,
the vehicle may come to a complete stop.

Warning function
The warning prompts the driver to intervene.
Principle
The Forward Collision Warning with braking
function is a warning function that notifies the
driver of a possible risk of collision and brakes
automatically as necessary.
Additional information:
Forward Collision Mitigation, refer to page 174.
In the event of an accident, the system helps
by reducing impact speed.

General information
Follow the system limits in the "Forward Colli-
sion Mitigation" chapter.
General information
Detection range
The following situations may not be detected,
or only detected with a delay, for instance:
▷
Vehicle driving slowly in front and being ap-
proached at high speed.
▷
Vehicles that suddenly swerve in front of
you, or strongly decelerating vehicles.
Sensors detect the traffic situation in their de-
tection range.
▷
▷
Vehicles with unusual rear designs.
Two-wheeled vehicles ahead of you.
The system issues a warning of a possible risk
of collision with vehicles at speeds above ap-
prox. 3 mph/5 km/h. The timing of warnings
may vary with the current driving situation.
Upper speed limit
If the vehicle speed exceeds approx.
155 mph/250 km/h, the system is deactivated
temporarily. As soon as the speed drops below
this value again, the system is reactivated.
The system considers the driver’s vehicle han-
dling when responding. If an active driving
