R By activating the hazard warning lights
If th eve hicle is braked sharply from speeds
abo ve50 km/h, the brake lamps flash rapidl y.
This pr ovides traf fic tr avelling behind you with an

If th eve hicle is tr avelling at speeds of more than
70 km/h at the beginning of the brake applica‐
tion, the hazard warning lights switch on once
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 the hazard warning lights
using the hazard warning button. Cruise control and limiter

yo u accelerate toove rtake, forex ample, the
st ored speed is not dele ted. If youre mo veyour

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
fo r maintaining a safe dis tancetotheve hicle in

and forst ay ing in lane.

Do not use cruise control in thefo llowing situa‐
tions:
R In traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
R On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
R Ifyo u are driving when visibility is poor.
Fu nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for speed limits, e.g. in built-up
areas.
R Perm anen t:for long-term speed restrictions,
e.g. when driving in winter tyre mode. The
variable limiter is operated using the cor re‐
sponding steering wheel buttons. You can store
any speed abo ve20 km/h up tothe maximum
speed or up tothe set winter tyre limit. You can
also per form settings while theve hicle is station‐
ary if theve hicle has been star ted.
If yo ufa ilto adapt your driving style, the limiter
can neither reduce therisk of an accident nor
ov erride the la wsof ph ysics. It cannot take into
account road, weather or traf fic conditions. The
limiter is only an aid. You are responsible for

% Active Steering Assist is count ry-dependent
and only available forve hicles with the Driv‐
ing Assis tance Package. Ac
tive Steering Assist is operational at speeds
up to210 km/h and helps youto stay inthe
centre of the lane bymeans of moderate steer‐
ing inter ventions. It uses theve hicle in front and
th e lane markings as a refere nce depending on
th e driven speed.
When the sy stem is actively steering, theè
symbol is shown in green in the multifunction
displa y.
If th e de tection of lane markings and vehicles
ahead is impaired, Active Steering Assist
switches topassive mode. The sy stem pr ovides
no support in this case. During the transition
from active topassive status, theè symbol is
shown as enlar ged and flashes yello w. Once the

Ste ering and touch de tection
The driver is requiredtokeep their hands on the
st eering wheel at all times and be able tointer‐

ve hicle and keep it in lane. The driver must
ex pect a change from active topassive mode or
vice versa at any time. If
th e sy stem reaches a sy stem limitation or the
driver has not steered theve hicle for a consider‐
able period of time or has remo vedth eir hands
