ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (

PRE-SAFE ® Brake
General information
i Observe the "Important safety notes" sec-
tion (
Y
page 68).
PRE-SAFE ® Brake is only available in vehicles
with DISTRONIC PLUS.
For PRE-SAFE
® Brake to assist you when driv-
ing, the radar sensor system must be opera-
tional.
With the help of the radar sensor system,
PRE-SAFE ® Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
PRE-SAFE
® Brake can help you to minimize
the risk of a collision with a vehicle ahead, and
reduce the effects of such a collision. If PRE-
SAFE ® Brake has detected a risk of collision,
you will be warned visually and acoustically as
well as by automatic braking. PRE-SAFE ®
Brake cannot prevent a collision without your
intervention.
Important safety notes
G WARNING
PRE-SAFE ® Brake will initially brake your vehi-
cle by a partial application of the brakes if a
danger of collision is detected. There may be
a collision unless you also brake. Automatic
emergency braking cannot prevent a colli-
sion. There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action.
G WARNING
PRE-SAFE ® Brake cannot always clearly iden-
tify objects and complex traffic conditions.
In these cases, PRE-SAFE
® Brake may:
R give an unnecessary warning and then
brake the vehicle
R not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE
® Brake warns you. Terminate the
intervention in a non-critical driving situation.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col-
lision, you must apply the brakes yourself.
G WARNING
PRE-SAFE ® Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ® 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, the rec-
ognition can be impaired.
Recognition by the radar sensor system is
also impaired in the event of:
R dirt on the sensors or anything else cover-
ing the sensors
R interference by other radar sources
R
strong radar reflections, for example in
parking garages
