PRE-SAFE ® Brake
General information
i Pay attention to the important safety
notes in the "Driving safety systems" sec-
tion (
Y
page 66).
PRE‑SAFE ® Brake is only available for vehi-
cles with the Driving Assistance package.
For PRE-SAFE
® Brake to assist you when driv-
ing, the radar sensor system and the camera
system must be switched on and be opera-
tional.
With the help of the radar sensor system and
the camera system, PRE-SAFE ® Brake can
detect obstacles that are in front of your vehi-
cle for an extended period of time.
In addition, pedestrians in the path of your
vehicle can be detected.
PRE-SAFE
® Brake detects pedestrians using
typical characteristics such as the body con-
tours and posture of a person standing
upright.
Observe the restrictions described in the
"Important safety notes" sec-
tion“ (
Y
page 74).
PRE-SAFE ® Brake can help you to minimize
the risk of a collision with a vehicle ahead or a
pedestrian, 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 brak-
ing.
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 brake yourself. Even
after subsequent full application of the brakes
a collision cannot always be avoided, partic-
ularly when approaching at too high a speed.
There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action, provided it is safe to do
so.
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.
PRE-SAFE
® Brake can also brake the vehicle
automatically under the following conditions:
R
the driver and front-passenger have their
seat belts fastened
and
R the vehicle speed is between approx-
imately 4 mph (7 km/h) and 124 mph
(200 km/h)
