Sy
stem limits
The sy stem may be impaired or may not function
in thefo llowing situations, forex ample:
R In sn ow,ra in, fog, heavy spr ay, if there is
gl are, in direct sunlight or in greatlyvarying
light conditions.
R The windsc reen in the area of the camera is
dirty, mis ted up, damaged or co vered.
R Ifth era dar sensors are dirty or co vered.
R In multi- stor ey car pa rks or on roads with
st eep uphill or downhill gradients.
R Ifth ere are nar rowvehicles in front, such as
bicycles or mo torcyc les.
In addition, on slippery roads, braking or accel‐
erating can cause one or se veral wheels tolose
traction and theve hicle could then skid.
Do not use Active Dis tance Assi stDISTRONIC in
th ese situations. &
WARNING Risk of accident from acceler‐
ation or braking byActive Dis tance
Assi stDISTRONIC
Ac tive Dis tance Assi stDISTRONIC may accel‐
erate or brake in thefo llowing cases, for
ex ample:
R Ifth eve hicle pulls away using Active Dis‐
ta nce Assi stDISTRONIC.
R Ifth estored speed is called up and is
considerably faster or slo werth an the
cur rently driven speed.
R IfAc tive Dis tance Assi stDISTRONIC no
longer de tects a vehicle in front or does
not react toreleva nt objects. #
Alw ays carefully obser vethe traf fic con‐
ditions and be ready tobrake at all
times. #
Take into account the tra ffic situation
before calling up thestored speed. &
WARNING Risk of accident due toinsuf‐
fi cient decele ration byActive Dis tance
Assi stDISTRONIC
Ac tive Dis tance Assi stDISTRONIC brakes
yo ur vehicle with up to50% of the possible
deceleration. If this decele ration is not su ffi‐
cient, Active Dis tance Assi stDISTRONIC
alerts you with a visual and acoustic warning. #
Adjust your speed and main tain a suita‐
ble dis tance from theve hicle in front. #
Brake theve hicle yourself and/or take
ev asive action. &
WARNING Risk of accident if de tection

Ac tive Dis tance Assi stDISTRONIC does not
re act or has a limited reaction:
R when driving on a dif fere nt lane or when
ch anging lanes Driving and parking

R when towing a trailer #
Ensure that the driven speed complies
with traf fic re gulations. #
Adjust the driving speed tosuit cur rent

nction of route-based speed adaptation
When Active Dis tance Assi stDISTRONIC is acti‐
va ted, theve hicle speed will be adap ted accord‐
ingly tothero ute events ahead. Depending on
th e drive prog ram selected, theve hicle negoti‐
ates a route event ahead in a fuel-s aving, com‐
fo rtable or dynamic manner. When thero ute
eve nt has been passed, theve hicle accelerates
again tothestored speed. The set dis tance to
th eve hicle in front, vehicles de tected ahead and
speed restrictions ahead are take n into account.
Ro ute-based speed adap tation can be acti vated
in the multimedia sy stem (/ page 236).
The following route events are take n into
account:
R Bends R
Roundabouts
R T-junctions
R Turns and exits
R Traf fic jams ahead (only wi thLive Traf fic )
Also, the speed is reduced if the turn signal indi‐
cator tochange lanes is swit ched on and one of
th efo llowing situations is de tected:
R Turning off at junctions
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 tojunctions, roundabouts
and traf fic lights, as route-based speed adap ta‐
tion does not brake theve hicle toast andstill.
If a cor responding route event is de tected while
ro ute guidance is active, thefirs t speed adjust‐
ment is car ried out automaticall y.Ifth e turn sig‐
nal indicator is switched on, the selected route is
confirmed and fur ther speed adjustment is acti‐
va ted. Speed adap
tation is cancelled in thefo llowing
cases:
R Ifth e turn signal indicator is switched off
before thero ute event and it is therefore
assumed that thero ute event is not releva nt
to the driver.
R Ifth e driver depresses the accelera tor or
brake pedal during the process.
Sy stem limits
Ro ute-based speed adaptation 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, the speed selection made
by the sy stem may not alw ays be suitable:
R unclear roads
R road nar rowing
R varying maximum permissible speeds in indi‐
vidual lanes, forex ample at tollst ations
R wetro ad sur faces, snow or ice
R if transport equipment, forex ample a trailer

Ac
tive Emergency Stop Assist issues thefo llow‐

R Display message 1appears in the driver
displa y.
R In addition todisplay 1awa rning tone
sounds.
R The Beginning emergency stop message
appears in the driver displa y,a continuous
wa rning tone sounds, theve hicle no longer
accelerates, and there is a slight, repeated
te nsioning of the seat belt.
R The vehicle speed is reduced in increments
until it is at a standstill. Sharp brake impul‐
ses are also produced.
Depending on the count ry, a lane change tothe
adjacent right-hand lane is car ried out, if possi‐
ble.
% It is only possible tochange across one lane
and on ly intotheright-hand lane, and not
onto the hard shoulder.
Depending on the count ry,th e hazard warning
lights are switched on when automatic braking is
initiated. When
theve hicle is stationar y,thefo llowing
actions are car ried out:
R The vehicle is secured with the electric park‐
ing brake.
R Active Dis tance Assi stDISTRONIC is ended
R The vehicle is unloc ked.
R If possible, an emer gency call is placed to
th e Mercedes-Benz emer gency call centre
Before au tomatic braking is initia ted, you can
cancel Active Emergency Stop Assist bysteer‐
