begins to lurch. ESP
®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has stabi-
lised.
Trailer stabilisation is active above speeds of
about 65 km/h. G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent
the trailer from swervin gand will thus be
unable to reduce the ris kofanaccident. Trail-
ers with a high centre of gravity can tip over
before ESP ®
can detect this.
Trailer stabilisation does not work if ESP ®
is
deactivated or disabled because of a mal-
function. EBD (electronic brake forc
edistribu-
tion)
i Observe the "Importan tsafety notes" sec-
tion (Y page 72).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
WARNING
If EB Dhas malfunctioned, the braking system
remains available with full brake boosting
effect .However, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident .You should therefore adapt your
driving style to the different handling charac-
teristics.
X Observe the notes on warning and indicator
lamps (Y page 293) as well as display mes-
sages (Y page 251) (4-button multifunc-
tion steering wheel) and ( Ypage 257) (12-
button multifunction steering wheel). 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 (Y page 193) and
hill start assist (Y page 156). For further
information, see Driving tips (Y page 175). PRE-SAFE
®
Brake
PRE-SAFE ®
Brake is only available in vehicles
with DISTRONIC PLUS.
i Observe the "Important safety notes" sec-
tion (Y page 72).
PRE-SAFE ®
Brake can help you to minimise
the risk of a frontal collision with a vehicle
ahead or reduce the effect sofsuch a colli-
sion. 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.
This function will issue a warning at speeds of
around 30 km/h or more if:
R for a period of several seconds, the dis-
tance to the vehicle in fron tis too short for
the speed at which you are travelling. The
· distance warning lamp then lights up
in the instrument cluster.
R you are rapidly approaching the vehicle in
front. An intermittent warning tone will
then sound and the ·distance warning
lamp will light up in the instrument cluster.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so. 78
Driving safety systemsSafety

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
