Due to the nature of the system, particularly
complicated but non-critical driving condi-
tions may also cause the system to display a
warning.
With the help of the radar sensor system, the
distance warning function can detect obsta-
cles that are in the path of your vehicle for an
extended period of time.
Up to a speed of around 40 mph (70 km/h),
the distance warning function can also react
to stationary obstacles, such as stopped or
parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision,
the system will initially alert you both visually
and acoustically.
In particular, the detection of obstacles can
be impaired if:
dirt on the sensors or anything else cover-
R
ing the sensors
there is snow or heavy rain
R
there is interference by other radar sources
R
there are strong radar reflections, for
R
example in parking garages
a narrow vehicle traveling in front, e.g. a
R
motorbike
a vehicle traveling in front on a different line
R
relative to the center of your vehicle
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.
Adaptive Brake Assist

Observe the "Important safety notes" sec-
tion for driving safety systems (
G WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
intervene unnecessarily
R
not intervene
R
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
WARNING
G
Adaptive Brake Assist does not react:
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
to stationary obstacles
R
when cornering
R
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
Due to the nature of the system, particularly
complicated but non-critical driving condi-
tions may also cause Brake Assist to inter-
vene.
Adaptive Brake Assist provides braking assis-
tance in hazardous situations at speeds
above 4 mph (7 km/h). It uses radar sensor
technology to assess the traffic situation.
With the help of Adaptive Brake Assist, the
distance warning signal can detect obstacles
that are in the path of your vehicle for an
extended period of time.
As soon as a risk of a collision is detected,
Adaptive Brake Assist calculates the braking
force necessary to avoid the collision. If you
apply the brakes forcefully, Adaptive Brake

Y
Assist will automatically increase the braking
force to a level suitable for the traffic condi-
tions.
Keep the brake pedal depressed until the
X
emergency braking situation is over.
ABS prevents the wheels from locking.
