several seconds. The · distance warn-

you are rapidly approaching the vehicle in

then sound and the · distance warning
lamp will light up in the instrument cluster.

Brake immediately in order to increase the
distance from the vehicle in front.
or

Take evasive action provided it is safe to do
so.
If the driver and passengers have fastened
their seat belts, PRE-SAFE ® Brake can also
can also perform the following at speeds of
above approximately 30 km/h:
R
brake the vehicle automatically from a
speed of up to approximately 200 km/h
R
trigger preventative passenger protection
measures (PRE-SAFE ® ) (

page 43)
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE
®
Brake. To end this,
you can either depress the accelerator pedal
further, activate kickdown or release the
brake pedal.
The braking action of PRE-SAFE
®
Brake is
ended automatically if:
R
you drive slower than approximately
15 km/h.
R
you manoeuvre to avoid the obstacle.
R
there is no longer any danger of a rear-end
collision.
R
there is no longer an obstacle detected in
front of your vehicle.
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.
At speeds up to approximately 70 km/h,PRE-
SAFE ® Brake can also detect stationary
obstacles, for example, stopped or parked
vehicles.
If you approach an obstacle and PRE-SAFE
®
Brake detects a risk of a collision, the system
will initially alert you both visually and acous-
tically. If you do not brake or take evasive
action, the system will warn you by automat-
ically braking the vehicle gently. If there is an
increased risk of collision, preventative
passenger protection measures (PRE-SAFE ® )
are activated (
Y
page 43). If the risk of colli-
sion remains and you do not brake, take eva-
sive action or accelerate significantly, the
vehicle may perform automatic emergency
braking. Automatic emergency braking is not
performed until immediately prior to an acci-
dent that can no longer be avoided.
G
WARNING
Even if PRE-SAFE ® Brake slows the vehicle
before an imminent rear-end collision, the
system cannot avert a collision without the
intervention of the driver. There is a risk of an
accident. Brake according to the situation or
take evasive action. Delayed intervention by
the driver can lead to an accident.
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 par-
ticular 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
