fety sy stems use
ra dar sensors tomonitor the area in front of,
behind or next totheve hicle (depending on the
ve hicle's equipment).
Depending on theve hicle's equipment, thera dar
sensors are integrated behind the bumpers
and/or behind the Mercedes star. Keep these
parts free of dirt, ice and slush (→ page 352).
The sensors must not be co vered, forex ample

set speed on free-flowing roads. If vehicles in
front are de tected, the set dis tance is main‐

ing on the dis tance totheve hicle in front and
th e set speed. The speed (in thera nge between
15 mp h (2 0 km/h) and 130mp h (2 10km/h))

Also,
the speed is reduced if the turn signal to
ch ange lanes is swit ched on and one of thefo l‐
lowing situations is de tected:
R Turning off at intersections
R Driving on slowing-down lanes
R Driving on lanes adjacent toslowing-down
lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tointersections, traf fic cir‐
cles and traf fic lights, as route-based speed
adap tation does not brake theve hicle toast and‐
st ill.

Speed adjustment is canceled in thefo llowing
cases:
R Ifth e turn signal indicator is switched off
before thero ute event. R
Ifth e driver depresses the accelerator or
brake pedal during the process.
Sy stem limitations
Ro ute-based speed adap tation does not take
ri ght of wayre gulations into account. The driver
is responsible for complying with road traf fic
re gulations and driving at a suitable speed.
In dif ficult conditions (e.g. unclear roads, nar row
lanes, wetro ad sur faces, snow or ice) or when
driving wi tha trailer, the speed adjustment made

Ac
tive Steering Assist Fu
nction of Active Steering Assist
Ac tive Steering Assist is count ry-dependent and
only available forve hicles with the Driving Assis‐
ta nce Package.
Ac tive Steering Assist is operational at speeds
up to130mp h (2 10km/h) and helps youto stay
in the center of the lane bymeans of moderate
st eering inter ventions. It uses theve hicle in front
and the lane markings as a refere nce depending
on the driven speed.
When the sy stem is actively steering, theè
symbol is shown in green in the multifunction
displa y.
Ste ering and touch de tection
The driver is requiredtokeep their hands on the
st eering wheel at all times and tobe able to
inter vene at any time. The driver mu stexpect a
ch ange from active topassive mode or vice
ve rsa 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, firs t alert the driver
with a visual warning. Display 1appears in the
multifunction displa y.Ifth e driver still does not
st eer theve hicle, or has still not take n hold of
th esteering wheel, a repeated warning tone
sounds in addition tothe visual warning mes‐
sage toremind the driver totake control of the
ve hicle.
The warning message does not appear or disap‐
pears if one of thefo llowing conditions are me t:
R The driver steers theve hicle. R
The driver presses a steering wheel button or
operates Touch Control.
Ac tive Steering Assist is only an aid. The driver is
re sponsible forth e dis tance totheve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane. Before changing lanes,
th e driver must make sure that the neighboring
lane is free (glance over the shoulder).
Sy stem limitations
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
ahead is impaired, Active Steering Assist
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.
Once the sy stem is passive theè symbol is
gr ay ed out in the multifunction displa y.17 2
