Driving and driving saf ety sy stems
Driving sy stems and your responsibility
Yo ur vehicle is equipped with driving sy stems
which assist you in driving, 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 338).
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, youwill 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 ! ABSwarning lamp lights up contin‐
uously in the instrument clus ter af terth e

Fu nction of BAS (Brake Assist Sy stem)
&
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.
#Depress the brake pedal with full forc e
in emer gency braking situations. ABS
pr eve nts the wheels from locking.

125mp h(2 00 km/h) when driving stra ight
ahead or cornering slightly.
RThe vehicle 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 requiredforve hicle stabilization.
This steering recommendation is given part icu‐
lar lyin 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.
Sy stem limitations
ST EER CONTROL may be impaired or may not
function in thefo llowing situations:
RESP®is deactivated.
RESP®is malfunctioning.
RThe steering is malfunctioning.
If ESP
®is malfunctioning, you will beassis ted
fur ther by the electric po werst eering.
Fu nction 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 bewarned visually and acousti‐
cally.
If yo udo not react tothe visual or acoustic warn‐
ing, autonomous braking can be initiated in criti‐
cal 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 uappl yth e brake yourself in a critical situa‐
tion or applyth e 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 measure sfo r occupant
pr otection (PRE-SAFE®) may also be initiated, if
th eve hicle is equipped with these.
