DSR (Downhill Speed
Regulation) Fu
nction of DSR (Downhill Speed Regulation)
DSR is an aid toassist you when driving down‐
hill. It keeps the speed of tr avel at the selected
ta rget speed. The steeper the downhill gradient,
th e greater the DSR braking ef fect on theve hi‐
cle. On flat stre tches of road and uphill gradi‐
ents, the DSR brakes theve hicle minimally or
not at all.
When DSR is activated and the transmission is in
position 005B,005Eor005C, DSR controls the driving
speed. The target speed can be set toava lue
between 2 km/h and 18km/h. By braking or
accele rating, you can drive at a higher or lo wer
speed than theta rget speed at any time.
DSR is deactivated automatically if you drive at
speeds greater than 45 km/h or select drive
program CorB. The îoffmessage
th en appears in the multifunction displa y.The
st atus indicator in the multifunction display dis‐
appears. You also hear a warning tone. In

WARNING Risk of skidding and having
an accident when DSR is acti vated on
slippery road sur faces
If th e speed driven and theta rget speed dif‐
fe r, and you activate DSR on a slippery road
sur face, the wheels may lose traction. #
Take into account thero ad sur face and
th e dif fere nce between the driving
speed and target speed before activat‐
ing DSR. If
yo ufa ilto adapt your driving style, DSR can
neither reduce therisk of an accident nor over‐
ri de the la wsof ph ysics. It cannot take into
account road, weather or traf fic conditions. DSR
is only an aid. You are responsible for maintain‐
ing a safe dis tance totheve hicle in front, for
ve hicle speed, for braking in good time and for
st ay ing in lane.
Yo u are alw aysre sponsible forke eping control of
th eve hicle and for assessing whe ther the down‐
hill gradient can be negotiated. Depending on
ro ad sur face and tyres, DSR may not al ways be able
tokeep totheta rget speed. Select a target
speed suitable forth e environmen tal conditions
and also apply the brakes yourself if requ ired.

Fu
nction of Active Speed Limit Assi st%
The following function is countr y-dependent
and only available in conjunction with the
Driving Assi stance Package. If a
change in the speed limit is de tected and
au tomatic adoption of speed limits is activated,
th e new speed is automatically adop ted as the
st ored speed (/ page 285). The driven speed is adjus
ted when theve hicle is
le ve l with the traf fic sign at the latest. In the
case of signs indicating entry into an urban area,
th e speed is adap ted according tothe speed
permitted within the urban area. The speed limit
display in the Instrument Display is alw ays upda‐
te d when theve hicle is le vel with the tra ffic sign.
If th ere is no speed restriction on an unlimi ted
st re tch of road (e.g. on a mo torw ay),th ere com‐
mended speed is au tomatical lyadop ted as the
st ored speed. The sy stem uses the speed stored
on an unlimited stre tch of road as there com‐
mended speed. If you do not alter thestored
speed on an unlimited stre tch of road, there c‐
ommended speed is 130 km/h.
If Ac tive Dis tance Assi stDISTRONIC has been
put into passi vemode bypressing the accelera‐
to r pedal, only speed limits which are higher
th an the set speed are adop ted.
Ac tive Speed Limit Assi stis only an aid. The
driver is responsible forke eping a safe dis tance
from theve hicle in front, forve hicle speed and
fo r braking in good time. The maximum permissi‐
ble speed also depends on factors su chasthe
ro ad sur face and traf fic conditions. Sy
stem limits
Te mp orary speed restrictions (e.g. for a cer tain
time or due towe ather conditions) cannot be
proper ly detected bythe sy stem. The maximum
permissible speed applying toave hicle with a
trailer is not de tected bythe sy stem. In these sit‐
uations you must adjust your speed yourself. &

Fu
nction of route-based speed adaptation %
The following function is countr y-dependent
and only available in conjunction with the
Driving Assi stance Package.
When Active Dis tance Assi stDISTRONIC is acti‐
va ted, theve hicle speed will be adjus 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 config‐
ured in the multimedia sy stem (/ page 238).
The following route events are take n into
account:
R Bends
R T-junctions, roundabouts and tollst ations
R Turns and exits
R Traf fic jams ahead (only wi thLive Traf fic
( / page 413)) %
When theto llst ation is reached, Active Dis‐
ta nce Assi stDISTRONIC adopts the speed as
th estored speed.
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.
When route guidance is active, thefirs t speed
adjustment is car ried out automaticall y.Ifthe
turn signal indica tor is switched on, the selected
ro ute is confirmed and fur ther speed adjustment
is activated. Speed adjustment is cancelled 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 limits
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, forex ample unclear roads,
lane nar rowing, wetro ad sur faces, snow or ice,
or when driving wi tha trailer, the speed adap ta‐
