Evasive Steering Assist
Evasive Steering Assist cann otalw ays clearly
identify objects and complex traf fic situa‐
tions.
In addition, thesteering support of Evasive
St eering Assist is general lynot su fficient to
avo id a collision. In such cases Evasive
Steering Assist can:
R give an unnecessary warning or pr ovide

St eering Assist alone. #
Beready tobrake and take evasive
action, if necessar y. #
Preve ntthe assis tance byactively steer‐

R Ifth e sensors are dirty, mis ted up, damaged
or co vered.
R Ifth e sensors are impaired due tointer fer‐

ra dar reflections in multi-s torey car par ks.
R If a loss of tyre pressure or a defective tyre
has been de tected and displ ayed.
R In complex traf fic situations whe reobjects
cannot always be clearly identified.
R If pedestrians or vehicles mo vequickly into

If th eve hicle is tr avelling at speeds of more than
70 km/h at the beginning of the brake applica‐

th eve hicle is stationar y.When you pull away
again, the hazard warning lights will switch off
automatically at appr oximately 10km/h. Yo u can also switch off

cruise control will resume speed regulation back
to thestored speed.
Cruise contro l is operated using the cor respond‐
ing steering wheel buttons. You can store any
speed abo ve20 km/h up tothe maximum speed
or up tothe set winter tyre limit.
If yo ufa ilto adapt your driving style, cruise con‐
trol can neither reduce therisk of an accident
nor override the la wsof ph ysics. It cannot take
into account road, weather or traf fic conditions.
Cruise control is only an aid. You are responsible

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 (/ page 205).
Shortly before the set speed is reached, it
appears in the multifunction displa y.When you
