Fu nction of PRE-SAFE®PLUS (anticipatory
occupant pr otection plus)
PRE- SAFE®PLUS can de tect cer tain impacts,
particular lyan imminent rear impact, and take
pre-em ptive measures toprotect theve hicle
occupants. These measures cannot necessarily
pr eve nt an imminent impact.
PRE-SAFE
®PLUS can implement thefo llowing
measures independently of each other:
RTightening the seat belts on the driver's seat
and front passenger seat.
RInc reasing brake pressure when theve hicle
is stationar y.This brake application is can‐
celed automatically when theve hicle pulls
aw ay.
If an accident did not occur, the pre-em ptive
measures that we retake n are reve rsed. Sy

Driving and driving saf ety sy stems
Driving sy stems and your responsibility
Yo ur vehicle is equipped with driving sy stems
which assist youin dr iving, parking and maneu‐
ve ring theve hicle. The driving sy stems are tools
and do not relie ve you of your responsibility. Pay
attention tothe tra ffic conditions at all times
and inter vene when necessary . Beaware of the
limitations rega rding the safe use of these sys‐
te ms.
Fu nction of thera dar senso rs
Some driving and driving safe ty systems use
ra dar sensors tomonitor the area in front of,
behind or next totheve hicle (depending on the
ve hicle's equipment).
Depending on theve hicle's equipment, thera dar
sensors are integrated behind the bumpers
and/or behind thera diator grille. Keep these
parts free of dirt, ice and slush (
→page 327).
The sensors must not be co vered, forex ample
by bicycle rack s, ove rhanging loads or radar-
re flecting sticke rs.Fo llowing an impact and in
th eeve nt of associated damage , which may not
be visible, tothe bumpers or radiator grille, ha ve
th e function of thera dar sensors checked at a
qu alified specialist workshop. The driver assis‐
ta nce sy stem may no longer workproperly.

Fu nctions of ABS (Anti-lock Brake Sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, e.g. at maximum full-s top
braking or insuf ficient traction of the tires,
th e wheels are pr evented from blocking.
RVehicle steerability while braking is ensured.
If ABS inter venes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
conditions and can ser veas a reminder totake
ex tra care while driving. Sy
stem limitations
RABS is active from speeds of appr ox. 5 mph
(8 km/h).
RABS may be impaired or may not function if a
malfunction has occur red and theye l‐

0071
WARNING Risk of an accident caused by
a malfunction in BAS (Brake Assist Sys‐
te m)
If BA S is malfunctioning, the braking dis tance
in an eme rgency braking situation is
increased.
00BBDepress the brake pedal with full forc e
in emer gency braking situations. ABS
pr eve nts the wheels from locking.
BA S suppo rts yo ur eme rgency braking situation

Fu nctions of ESP®Crosswind Assist
ESP®Crosswind Assist de tects sudden gust s of
side wind and helps the driver tokeep theve hi‐
cle in the lane:
RESP®Crosswind Assist is active at vehicle
speeds between 50 mph(8 0 km/h) and
12 5mp h(2 00 km/h) when driving stra ight
ahead or cornering slightly .
RThevehicle is stabilized bymeans of individ‐
ual brake application on one side.
Fu nction of EBD (Electronic Brake forc e Dis‐
tribution)
EBD is characterized bythefo llowing:
RMonitoring and regulating the brake pressure
on there ar wheels.
RImpr oved driving stability when braking,
especially on bends.
ST EER CONT ROL function
STEER CONTROL helps youby transmitting a
noticeable steering forc eto thesteering wheel in
th e direction requ ired forve hicle stabilization.
This steering recommendation is given part icu‐
larly in thefo llowing situations:
RBo th right wheels or bo thleft wheels are on
a we t or slippe ryroad sur face when you
brake.
RThe vehicle starts toskid.

0071WARNING Risk of an accident despite
Evasive Steering Assist
Evasive Steering Assist cannot always clearly
identify objects and complex traf fic situa‐
tions.
In addition, thesteering support of Evasive
St eering Assist is general lynot suff icientto
avo id a collision.
In such cases Evasive Steering Assist can:
Rgive an unnecessary warning or pr ovide
assis tance
Rnot give awa rning or not pr ovide assis‐
ta nce
00BBAlw ays pay careful attention tothe traf‐
fi c situation; do not rely on Ev asive
St eering Assist alone.
00BBBe ready tobrake and take evasive
action if necessar y.
00BBPreve ntthe assis tance byactively steer‐
ing in non-critical driving situations.
00BBDrive at an appropriate speed if pedes‐
trians are close tothe path of your vehi‐
cle.
Also obser vethe sy stem limitations of Evasive
St eering Assist.
Sy stem limitations
The sy stem may be impaired or may not function
in thefo llowing situations:
RIn sno w,rain, fog, heavy spr ay, if there is
gl are, in direct sunlight or in greatlyvarying
light conditions.
RIf th e sensors are dirty, mis ted up, damaged
or co vered.
RIfth e sensors malfunction due to otherradar
source inter fere nce, forex ample stro ng radar
re flections in parking garage s.
RIf a loss of tire pressure or a defective tire
has been de tected and displ ayed.
The sy stem may not react cor rectly:
RIn complex traffic situations whe reobjects
cannot always be clearly identified.
RTo pedestrians or vehicles if they mo ve
qu ickly into the sensor de tection range.
RTo pedestrians who are hidden by other
objects.
RIf th e typical outline of a pedestrian cannot
be distinguished from the bac kground.
RIf a pedestrian isnot recognized as such , e.g.
due tospecial clo thing or other objects.
ROn bends with a tight radius.
