WARNING
If EB Dhas malfunctioned ,the rear wheels can
still lock, e.g .unde rfull braking .This increa-
ses the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at aqualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 261) as well as dis-
play messages (Y page 234).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort.Ina ddi-

PRE-SAFE ®
Brake is onl yavailable in vehicles
with DISTRONI CPLUS.
PRE-SAFE ®
Brake can hel pyou to minimise
the ris kofacollision with avehicle ahea dor
reduce the effects of such acollision. If PRE-
SAFE ®
Brake detects ariskofc ollision, you
will be warned visually and acoustically as
well as by automatic braking. PRE-SAFE ®
Brake cannot prevent acollision without your
intervention. 68
Driving safety systemsSafety

This function will issue
awarning if:
R at speeds of around 30 km/ho rmore, over
several seconds, the distance maintained
to the vehicle travelling in front is insuffi-
cient.
The · distance warning lamp then lights
up in the instrument cluster.
R at as peed of approximately 7km/h or
higher, you very quickly approach avehicle
in front.
An intermittent warning tone willt hen
sound and the ·distance warning lamp
willl ight up in the instrument cluster.
X Brake immediately in order to increase the
distance from the vehicl einfront.
or
X Take evasive action provided it is safe to do
so.
From aspee dofa pproximatel y7km/h,ifthe
driver and passengers have fastened their
seat belts, PRE-SAFE ®
Brake can brake the
vehicl eautomatically at speeds up to approx-
imatel y200 km/h.
Due to the nature of the system, particularly
complicate ddriving conditions may cause
unnecessary warnings or the unnecessary
interventio nofPRE-SAFE ®
Brake.
You can prevent the interventio nofthe PRE-
SAFE ®
Brake at any time by:
R depressing the accelerato rpedal further
R activating kickdown
R releasing the brake pedal.
The brakin gaction of PRE-SAFE ®
Brak eis
ended automatically if:
R you manoeuvre to avoid the obstacle.
R ther eisnol onger any danger of arear-end
collision.
R ther eisnol onger an obstacle detected in
fron tofy our vehicle.
With the help of the radar sensor system,
PRE-SAFE ®
Brak ecan detec tobstacles that
are in fron tofyour vehicle for an extended
period of time. At speeds up to approximately 70 km/h, PRE-
SAFE
®
Brak ecan also detec tstationary
obstacles such as stopped or parked vehi-
cles.
If you approach an obstacle and PRE-SAFE ®
Brak edetects arisk of acollision, 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 ther eisanincreased risk
of collision, preventativ epassenger protec-
tion measures (PRE-SAFE ®
)a re activated
(Y page 48). If, at speeds over 30 km/h, arisk
of collision remains and you do not brake,
take evasive action or significantly acceler-
ate, automatic brakin gmay be performed up
to alevel of automatic emergency braking.
Automatic emergency brakin gisnot per-
formed until immediately prior to an accident
that can no longer be avoided. G
WARNING
PRE-SAFE ®
Brak ewill initially brake your vehi-
cle by apartial application of the brakes if a
danger of collision is detected. There may be
ac ollision unless you also brake. Automatic
emergency braking cannot preven tacolli-
sion. There is arisk of an accident.
Always apply the brakes yourself and try to
take evasive action. G
WARNING
PRE-SAFE ®
Brak ecannot alway sclearly iden-
tify objects and complex traffic conditions.
In these cases, PRE-SAFE ®
Brak emay:
R give an unnecessary warning and then
brake the vehicle
R neither give awarning nor intervene
There is arisk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE ®
Brak ewarns you. Terminate the
intervention in anon-critical driving situation. Driving safet

R dirt on the sensors or anything else cover-
ing the sensors
R snow or heavy rain
R interference by other radars ources
R the possibility of strongr adar reflections,
for example, in multi-storey car parks
R an arrow vehicle travelling in front,e .g. a
motorcycle
R av ehicle travelling in front on adifferent
line G
WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossin gtraffic
R when cornering
As aresult, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical sit-
uations. There is arisk 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 acol-
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 219).
When PRE-SAFE ®
Brake is activated, the
