Ac tive Brake Assi stcan help youto minimise the
ri sk of a collision with vehicles or pedestrians or
to reduce the ef fects of su cha collision.
If Ac tive Brake Assi sthas de tected a risk of colli‐
sion, a warning tone sounds and the· dis‐
ta nce warning lamp lights up in the instrument
clus ter.
If yo u do not react tothewa rning, autonomous
braking can be initiated in critical situations.
In especially critical situations, Active Brake
Assi stcan initia teautonomous braking direct ly.
In this case, thewa rning lamp and warning tone
occur simultaneously wi th the braking applica‐
tion. If
yo u apply the brake yourself in a critical situa‐
tion or apply the brake during autonomous brak‐

If th e autonomous braking function or the situa‐

additional pr eventive measures for occupant
pr otection (PRE-SAFE ®

% 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

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
from thesteering wheel, the sy stem will,
depending on the situation, alert the driver
either with a visual warning or a visual and
acoustic warning. Display 1appears in the mul‐

If th e driver does not steer theve hicle over a
long period, or has not take n hold of thesteering
