WARNING
The automatic braking intervention is done
with limited force and duration.
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated,
e.g., approach control warning with light brak‐
ing function. There is a risk of an accident.

A camera in the area of the rearview mirror
controls the system.
The approach control warning is available even
if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the approach control warning and
braking are delayed in order to avoid false sys‐
tem reactions.
Overview
Button in the vehicle
General information
The system warns at two levels of an imminent
danger of collision at speeds from approx.
3 mph/5 km/h. Time of warnings may vary with
the current driving situation.
Appropriate braking kicks in at speeds of up to
35 mph/60 km/h.
Detection range

Camera
Objects are responded to if they are detected
by the system.
Safety information
The camera is installed near the interior mirror.
WARNING
Keep the windshield in front of the interior mir‐

Prewarning
This warning is issued, e.g., when there is the
impending danger of a collision or the distance
to the vehicle ahead is too small.

The driver must intervene actively when there
is a prewarning.

Acute warning with braking function
▷
All Intelligent Safety systems are
switched off.
The LED goes out.
Acute warning is displayed in case of the immi‐
nent danger of a collision when the vehicle ap‐
proaches another object at a high differential
speed.
Setting the warning time
The warning time can be set via iDrive.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking inter‐
vention in a possible risk of collision.

Acute warnings can also be triggered without
previous forewarning.
3. Activate the desired time on the Control
Display.
Braking intervention
The selected time is stored for the profile cur‐
rently used.
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used. Prerequisite for the brake
booster is sufficiently quick and hard stepping
on the brake pedal. The system can assist with
some braking intervention if there is a risk of a

collision. At low speeds vehicles may thus
come to a complete stop.

If the driving stability control systems are
limited or deactivated, e.g., DSC OFF.
The braking intervention is executed only if ve‐
hicle stability has not been restricted, e.g., by
deactivating the DSC Dynamic Stability Con‐
trol.
If, depending on the vehicle equipment
version, the field of view of the camera in
the mirror or the radar sensor is dirty or ob‐
scured.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.

System limits
Warning sensitivity
Safety information
The more sensitive the warning settings are,
such as the warning time, the more warnings
are displayed. However, there may also be an
excess of false warnings.
WARNING
The system can react incorrectly or not
at all due to the system limits. There is a risk of
accidents or risk of property damage. Observe
the information regarding the system limits
and actively intervene, if needed.◀

braking function
Detection range
The system's detection potential is limited.
The concept
The system can help prevent accidents. If an
accident cannot be prevented, the system will
help reduce the collision speed.
Thus, a system reaction might not come or
might come late.
E.g., the following situations may not be de‐
tected:
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
▷
Slow moving vehicles when you approach
them at high speed.
The automatic braking intervention may be
executed with maximum braking force and for
a brief period only as necessary.
▷
Vehicles that suddenly swerve in front of
you, or sharply decelerating vehicles.
▷
▷
Vehicles with an unusual rear appearance.
Two-wheeled vehicles ahead of you.
If the vehicle is equipped with Active Cruise
Control with Stop&Go, the front-end collision
warning is controlled via the cruise control ra‐
dar sensor in conjunction with a camera.
Functional limitations
The system may not be fully functional in the
following situations:
The front-end collision warning is available
even if cruise control has been deactivated.
▷
In heavy fog, rain, sprayed water or snow‐
fall.
With the vehicle approaching another vehicle
intentionally, the collision warning and braking
