If you approach an obstacle and PRE-SAFE
®
Brake detects a risk of a collision, the system
will alert you both visually and acoustically. If
you do not brake or take evasive action, the
system will warn you by automatically braking
the vehicle gently. If there is an increased risk
of collision, preventative passenger protec-
tion measures (PRE-SAFE ® ) are activated
(
Y
page 48). If, at speeds over 30 km/h, a risk
of collision remains and you do not brake,
take evasive action or significantly acceler-
ate, automatic braking may be performed up
to a level of automatic emergency braking.
Automatic emergency braking is not per-
formed until immediately prior to an accident
that can no longer be avoided.
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
neither give a warning nor 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 particular, the detection of obstacles can
be impaired if there is:
R
dirt on the sensors or anything else cover-
ing the sensors
R
snow or heavy rain
R
interference by other radar sources
R
the possibility of 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
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 order to maintain the appropriate distance
to the vehicle in front and thus prevent a col-
lision, you must apply the brakes yourself.

To activate/deactivate: activate or deac-
tivate PRE-SAFE
®
Brake in the on-board
computer (
Y
page 237).
When PRE-SAFE
®
Brake is activated, the
Ä symbol appears in multifunction dis-
play, as long as the HOLD function is deac-
tivated (
Y
page 186). On vehicles with the
Active Parking Assist driving system, the
Ä symbol is displayed when position P
is engaged or you are driving faster than
35 km/h.
For PRE-SAFE
®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on (
Y
page 243) and be opera-
tional.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities in the following vehicles:
R
vehicles with COMAND Online and naviga-
tion
R
vehicles with Audio 20 and Becker ® MAP
