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‐
cally.
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‐
tion-dependent braking assis tance is trig gered,
additional pr eventive measures for occupant
pr otection (PRE-SAFE ®
) may also be initiated, if
th eve hicle is equipped with these. &

nction of Steering Pilot
Ste ering Pilot is only available forve hicles
with the Driving Assistance Package.
R Steering Pilot is operational at speeds up to
21 0 km/h and helps youto stay inthe cent re
of the lane bymeans of moderate steering
inter ventions. R
It uses as a refere nce theve hicle in front or
th e lane markings, depending on the driven
speed.
R Steering Pilot requ ires you as the driver, to
ke ep your hands on thesteering wheel at all
times so that you are able tointer vene at any
time tocor rect the course of theve hicle and
ke ep it in lane.
R Steering Pilot can be overridden at any time
by steering theve hicle yourself.
R Ifth e sy stem de tects that there are no lane
markings, it uses theve hicle ahead as a ref‐
erence up toa speed of 130 km/h.
R When the sy stem is actively steering, the
è symbol is shown in green in the multi‐
function displa y.
Sy stem limitations of Steering Pilot
St eering Pilot has a limited steering torque for
lateral guidance. In some cases, thesteering
inter vention is not su fficient tokeep theve hicle
in the lane.
If de tection of lane markings and vehicles ahead
is impaired, Steering Pilot switches topassive
mode. The sy stem pr ovides no support in this 19 0

St eering Pilot remains active even if the turn sig‐
nal indicator is switched on. Steering Pilot then
assists the driver when changing lanes byapply‐
ing steering torques toinitiate the lane change.
Assis tance when changing lanes is pr ovided if all
th efo llowing conditions are me t:
R You are driving on a mo torw ay or high-speed
multi-lane major road with multiple lanes in
th e direction of tr avel.
R The neighbouring lane is free and separated
by a broken lane marking.
R The driven speed is between 80 km/h and
18 0 km/h.
R The turn signal indicator is switched on for

R Ifth e doors are open.
R The side mir rors are folded in.
R Ifth e boot lid or tailgate is open.
R There is heavy rain, snow or fog.
R The light conditions are poor, e.g. at night.

collide with objects when parking theve hicle. On
vehicles with height-adjus table suspension or
if th eve hicle is car rying a heavy load, leaving the
