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‐
low 0025 ABSwarning lamp lights up contin‐
uously in the instrument clus ter af terth e

Fu nction of BAS (Brake Assist Sy stem)
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
with additional brake forc e.

sure.
RBA S can short enthe braking dis tance.
RABS pr events the wheels from locking.
The brakes will function as usual once you
re lease the brake pedal. BAS is deactivated.

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.

ST EER CONTROL may be impaire d or may not
function in thefo llowing situations:
RESP®is deactivated.
RESP®is malfunctioning.
RThe steering is malfunctioning.

Function of Active Brake Assi st
Active Brake Assi stconsist s of:
RDistance warning function
RAu tonomous braking function
RSituation-dependent braking assist ance
RVehicles with Driving Assistance Pack‐
age: Evasi veSteering Assist
Ac tive Brake Assi stcan help youto minimize the
ri sk of a collision with vehicles or pedestrians or
to reduce the ef fects of such a collision.
If Ac tive Brake Assi sthas de tected a risk of colli‐
sion, youwill be warned visually and acousti‐
cally.
If yo udo not react tothe visual and audible colli‐
sion warning, autonomous braking can be initi‐
ated in critical situations.
In especially critical situations, Active Brake
Assi stcan initiate autonomous braking direct ly.
In this case, the visual and acoustic warning
occurs simultaneously with the braking applica‐
tion. If
yo u apply the brake yourself ina critical situa‐
tion or apply the brake during autonomous brak‐
ing, situation-dependent braking assis tance
occurs . This increases the brake pressure up to
maximum full-s top braking if necessar y.
If th e autonomous braking function or the situa‐
tion-dependent braking assis tance is trig gered,
additional pr eventive measures for occupant
pr otection (PRE-SAFE
®) may also be initiated, if
th eve hicle is equipped with these.
0071
WARNING Risk of an accident caused by
limited de tection per form ance of Active
Brake Assi st
Ac tive Brake Assi stcannot al ways clearly
identify objects and complex traffic situa‐
tions.
In such cases,Active Brake Assi stmight:
RGive a warning or brake without reason
RNot give a warning or not brake
00BBAlw ays pay careful attention tothe traf‐
fi c situation; do not rely on Active Brake
Assi stalone. Active Brake Assi stis only
an aid. The driver is responsible for
maintaining a sui table dis tance tothe
ve hicle in front, vehicle speed and for
braking in good time.
00BBBe prepared tobrake or swer veif nec‐
essar y.
Also obser vethe sy stem limitations of Active
Brake Assi st.
The individual subfunctions are available in
th efo llowing speed ranges:
Distance warning function
The dis tance warning function issues a warning
at speeds:
RFr om appr oximately 4 mph (7 km/h), if your
ve hicle is critically close toave hicle or
pedestrian. An intermittent warning tone
sounds and the00BA distance warning lamp
lights up in the instrument clus ter.
Brake immediately or take evasive action, pr ovi‐
ded it is safe todo so and the traf fic situation
