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, you will be warned visually and acousti‐
call y.
If yo u do 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 initia teautonomous braking direct ly.
In this case, the visual and acoustic warning
occurs simultaneously with the braking applica‐
tion.
If yo u apply the brake yourself in a critical situa‐
tion or apply the brake during autonomous brak‐
ing, situation-dependent braking assis tance
occu rs. The brake pressure increases up tomax‐
imum full-s top braking if necessar y.
If th e autonomous braking function or the situa‐

additional pr eventive measu resfo r occupant
pr otection (PRE-SAFE ®
) may also be initiated, if

R Active Steering Assist is operational at
speeds up to210 km/h and helps youto stay
in the cent reofthe lane bymeans of moder‐
ate steering inter ventions.
R It uses theve hicle in front and the lane mark‐
ings as a refere nce depending on the driven
speed.
R Active Steering Assist requ ires you as the
driver, tokeep your hands on thesteering
wheel at all times so that you are able to
inter vene at any time tocor rect the course of
th eve hicle and keep it in lane.
R Active Steering Assist can be overridden at
any time bysteering theve hicle yourself.
R When the sy stem is actively steering, the

stem limitations of Active Steering Assist
Ac tive Steering Assist has a limited steering tor‐
qu efo r lateral guidance. In some cases, the
st eering inter vention is not su fficient tokeep the
ve hicle in the lane.
If th e de tection of lane markings and vehicles

switches topassive mode. The sy stem pr ovides
no support in this case. During the transition
from the active topassive status, theè sym‐
bol is shown as enlar ged and flashes yello w.
