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 ®
) (Y page 51)
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 radars ensor 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 may also detec tstationary
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 syste mwill 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 51). 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 warnin gand then
brake the vehicle
R not give a warning or intervene
There is a ris kofanaccident. Always pay par-
ticula rattention to the traffi csituation 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
motorbike
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 Driving safety systems

As a result, PRE-SAFE
®
Brake may not give
warnings or intervene in critical situations.
There is a ris kofanaccident. Always pay
careful attention to the traffi csituation 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.
X To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 237).
The Ä symbol appears in the multifunc-
tion display as long as the HOL Dfunction
is not activated (Y page 193).
On vehicles with parking guidance, the
Ä symbol is displayed when Pis
engaged or you are driving faste rthan
35 km/h.
Vehicles with COMAND and navigation sys-
tem: the radar sensor system is switched off
automatically in the vicinity of radio telescope
facilities (Y page 389).
Vehicles without COMAND and a navigation
system and vehicles for Australia: the radar
sensor system and on-board computer must
be switched off in the vicinity of radio tele-
scope facilities (Y page 242).
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on (Y page 242) and be opera-
tional.
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle. Anti-theft systems

WARNING
Only for the United Kingdom: if the vehicle
has been locked with the key, the double lock
function is activated as standard. It is then not
possible to open the doors from inside the
vehicle.
Therefore, do not leave any people behind in
the vehicle, particularly children, elderly peo-
ple or people in need of special assistance if
the vehicle has been locked with the key. As
a result, they may not be able to free them-
selves in the event of an emergency. As a
result, they could be seriously or even fatally
injured by prolonged exposure to extremely
high or low temperatures, for example. In this
case, rescuing people from outside the vehi-
cle is difficult.
Deactivate the interior motion sensor before
you lock the vehicle with the key. The doors
can then be opened from the inside after the vehicle has been locked from the outside with
the key. G

If children are left unsupervised in the vehicle,
they could:
R open a door from inside the vehicle at any
time, even if it has been locked
R start the vehicle using akey which has been

They could thereby endanger themselves and
others. Never leave children unsupervised in
the vehicle. Always take the key with you
when leaving the vehicle, even if you are only
leaving it for a short time. G
WARNING
If a key ring is too heavy or too large, the
weight acting on the key could cause it to turn
in the ignition lock or catch on the steering
wheel. This could cause the engine to be
switched off suddenly. You may lose control
of the vehicle and cause an accident. Do not
attach any heavy or large key rings to the key
that is inserted in the ignition. :
