Always pay careful attention to the traffic
situation and be ready to brake.

WARNING
Active Brake Assist with cross-traffic func-
tion does not react:
R
to small people, e.g. children
R
to animals
R
to oncoming vehicles
R
when cornering
As a result, Active Brake Assist with cross-
traffic function may not warn you or engage
in all critical situations. There is a risk of an
accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In the event of snowfall or heavy rain, the rec-
ognition can be impaired.
Recognition by the radar sensor system is also
impaired if:
R
there is dirt on the sensors or anything else
covering the sensors
R
there is interference by other radar sources
R
there are strong radar reflections, for exam-
ple in parking garages
R
a narrow vehicle is traveling in front, e.g. a
motorbike
R
a vehicle is traveling in front on a different
line
R
vehicles quickly move into the radar sensor
system detection range
Recognition 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
or if:
-
pedestrians move quickly, e.g. into the
path of the vehicle
-
the camera system no longer recognizes 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 configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to collisions
at slow speeds where there is no visible dam-
age to the front of the vehicle.
Following damage to the windshield, have the
configuration and operation of the camera sys-
tem checked at a qualified specialist work-
shop.
Function
To avoid a collision, Brake Assist with cross-
traffic function calculates the brake force nec-
essary if:
R
you approach an obstacle, and
R
Brake Assist with cross-traffic function has
detected a risk of collision
When driving at a speed under 20 mph
(30 km/h): if you depress the brake pedal,
Brake Assist with cross-traffic function is acti-
vated. The increase in brake pressure will be
carried out at the last possible moment.
When driving at a speed above 20 mph
(30 km/h): if you depress the brake pedal
sharply, Brake Assist with cross-traffic func-
tion automatically increases the brake pres-
sure to a degree suited to the traffic situation.
Brake Assist with cross-traffic function pro-
vides braking assistance in hazardous situa-
tions with vehicles in front within a speed
range between 4 mph (7 km/h) and 155 mph
(250 km/h).
