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 manoeu‐
vring theve hicle. The driving sy stems are only
aids. They are not a substitute foryo ur attention
to the sur roundings and do not relie ve you of
yo ur responsibility per taining toroad traf fic la w.
The driver is alw aysre sponsible for maintaining
a safe dis tance totheve hicle in front, forve hicle
speed, for braking in good time and forst ay ing
in lane. Pay attention tothe tra ffic conditions at
all times and inter vene when necessary . Be
aw are of the limitations rega rding the safe use of
th ese sy stems. Driving sy
stems can neither reduce therisk of
accident if youfa ilto adapt your driving style nor
ove rride the la wsof ph ysics. They cannot alw ays
ta ke into account road, weather or traf fic condi‐
tions. Driving and park

Fu
nction of ABS The Anti-lock Brake Sy
stem (ABS) regulates the
brake pressure in critical driving situations:
R During braking, e.g. at full brake application
or insuf ficient tyre traction, the wheels are
pr eve nted from lock ing.
R Vehicle 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. Fu
nction of BAS The Brake Assist Sy
stem (BAS) supports your
eme rgency braking situation with additional
brake forc e.
If yo u depress the brake pedal quickl y,BA S is
acti vated:
R BAS au tomatically boosts the brake pres‐
sure.
R BAS can sho rten the braking dis tance. R
ABS pr events the wheels from locking.
The brakes will function as usual once you
re lease the brake pedal. BAS is deactivated. Fu

at speeds:
R From appr oximately 30 km/h, if over se veral

lamp then lights up in the instrument clus ter.
R From appr oximately 7 km/h, if your vehicle
is critically close toave hicle or pedestrian.
An intermittent warning tone sounds and the
L distance warning lamp lights up in the

If th eve hicle should ne verexc eed a specific
speed (e.g. for driving in winter tyre mode), you
can set this speed with the permanent limiter.
Yo u do this by limiting the speed toava lue
between 160 km/h and 240 km/h in the multi‐
media sy stem (/ page141).
Shortly before the set speed is reached, it
appears in the multifunction displa y.When you
confirm the message, display messages no lon‐
