obstacles that are in the path of your vehicle for
an extended period of time. If the distance warn-
ing function detects that there is a risk of a col-
lision, you will be warned visually and, where
necessary, acoustically. Without your interven-
tion, the distance warning function cannot pre-
vent a collision.
The distance warning function issues a warning
at speeds:
R
from about 30 km/h if, over several seconds,
the distance maintained to the vehicle travel-
ling in front is insufficient for the speed being
driven. The
·
warning lamp in the instru-
ment cluster then lights up.
R
from about 7 km/h if you approach a vehicle
travelling in front or a stationary vehicle too
quickly. The
·
warning lamp in the instru-
ment lights up and an intermittent warning
tone also sounds.
At speeds up to about 70 km/h, the system
also detects stationary obstacles, for exam-
ple stopped or parked vehicles.
X
Brake immediately until the distance from the
obstacle increases and the risk of a front-end
collision passes.
or
X
Take evasive action, provided it is safe to do
so.
Adaptive Brake Assist
General notes
Adaptive Brake Assist evaluates the traffic sit-
uation with the help of the radar sensor system
and can detect obstacles which have been in
your vehicle's path for an extended period of
time. From speeds above 7 km/h, Adaptive
Brake Assist aids you in braking during hazard-
ous situations.
Up to a speed of approximately 200 km/h,
Adaptive Brake Assist is capable of reacting to
moving obstacles that have already been detec-
ted as such at least once over the period of
observation.
Important safety notes
G
WARNING
Adaptive Brake Assist does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
to stationary obstacles
R
when cornering
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.
G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
R
intervene unnecessarily
R
not intervene
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.
In particular, the detection of obstacles can be
impaired in the case of:
R
dirt on the sensors or anything else covering
the sensors
R
snow or heavy rain
R
interference from other radar sources
R
strong radar reflections, for example, in multi-
storey car parks
R
a narrow vehicle travelling in front, e.g. a
motorbike
R
a vehicle travelling in front on a different line
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause Adaptive Brake Assist to inter-
vene.
If you fail to adapt your driving style, Adaptive
Brake Assist can neither reduce the risk of acci-
dent nor override the laws of physics. Adaptive
Brake Assist cannot take into account road,
weather or traffic conditions. Adaptive Brake
Assist is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed, braking in good time and for staying in
your lane.
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
