Brake may neither
give warnings nor intervene in all critical sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In the event of snowfall or heavy rain, detec-
tion can be impaired.
Detection by the radar sensor system is also
impaired in the event of:
R
dirt on the sensors or obscured sensors
R
interference by other radar sources
R
strong radar reflections, for example, in
multi-storey car parks
R
a narrow vehicle travelling in front, e.g. a
motorcycle
R
a vehicle travelling in front on a different
line
Detection by the camera system is also
impaired in the event of:
R
dirt on the camera or if the camera is cov-
ered
R
glare on the camera system, e.g. from the
sun being low in the sky
R
darkness
R
if:
-
pedestrians move quickly, e.g. into the
path of the vehicle
-
the camera system no longer detects a
pedestrian as a person due to special
clothing or other objects
-
a pedestrian is concealed by other
objects
-
the typical outline of a person is not dis-
tinguishable from the background
Following damage to the front end of the vehi-
cle, have the radar sensor settings and oper-
ation checked at a qualified specialist work-
shop. This also applies to collisions at slow
speeds where there is no visible damage to
the front of the vehicle.
Following damage to the windscreen, have
the configuration and operation of the cam-
era system checked at a qualified specialist

so.
If there is an increased risk of collision, pre-
ventive passenger protection measures (PRE-
SAFE

) are activated.
If the risk of collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking,
up to the point of full brake application. Auto-
matic emergency braking is not performed
until immediately prior to an imminent acci-
dent.
