Function of Active Distance Assist DISTRONIC
DIS
TRONIC Active Distance Assist maintains the
set speed when driving freely. If vehicles are
detected ahead, the set distance is maintained, if
necessary until the vehicle comes to a standstill.
The vehicle accelerates or brakes depending on
the distance to the vehicle in front and the set
speed. The speed and distance to the vehicle in
front are set and saved using the steering wheel.
Available speed range: = Vehicles without Driving Assistance Package:
20 km/h - 160 km/h =
V
ehicles with Driving Assistance Package:
20 km/h - 210 km/h
% The adjustable set speed may diMer if a limit

TRONIC:
= Adjusts the driving style depending on the
selected drive program (fuel-saving, comforta-
ble or dynamic) ( page 197)
= Initiates acceleration to the stored speed if the
turn signal indicator is switched on to change
to the overtaking lane
= Vehicles with Driving Assistance Package:
- Reacts to stationary vehicles detected in
urban speed ranges (except bicycles and
motorcycles)
- Takes one-sided overtaking restrictions
into account on motorways or on multi-
lane roads with separate carriageways
(country-dependent)
% In the DYNAMIC SELECT menu, it is possible
t

o set the driving mode of the Active Distance Assist DISTRONIC. Depending on which drive
pr

ogram is selected, the driving characteris-
tics can be geared towards energy economy,
comfort or dynamic performance. In the
Active Distance Assist menu, the driving style
can be permanently set to Comfort or
Dynamic (  page 255).
Vehicles with Active Parking Assist and Driving
Assis
tance Package: if Active Distance Assist
DISTRONIC has braked the vehicle to a standstill,
it can automatically follow the vehicle in front
when driving oM again within 30 seconds. If a criti-
cal situation is detected in the surrounding area
when driving oM, such as a person in the vehicle
path, a visual and acoustic warning is given indi-
cating that the driver must now take control of the
vehicle. The vehicle is not accelerated any further.

WARNING Risk of accident fr om accelera-
tion or braking by Active Distance Assist
DISTRONIC
Active Distance Assist DISTRONIC may accel-
er
ate or brake in the following cases, for
example:
= If the vehicle pulls away using Active Dis-
tance Assist DISTRONIC.
= If the stored speed is called up and is con-
siderably faster or slower than the cur-
rently driven speed.
= If Active Distance Assist DISTRONIC no
longer detects a vehicle in front or does
not react to relevant objects. 
Always carefully observe the tr
aPc con-
ditions and be ready to brake at all
times. 
Take into account the tr
aPc situation
before calling up the stored speed. &
WARNING Risk of accident due t
o insuP-
cient deceleration by Active Distance
Assist DISTRONIC
Active Distance Assist DISTRONIC brakes your
v
ehicle with up to 50% of the possible deceler-
ation. If this deceleration is not suPcient,
Active Distance Assist DISTRONIC alerts you
with a visual and acoustic warning. 
Adjust your speed and maintain a suita-
ble dis
tance from the vehicle in front. 
Brake the vehicle yourself and/or take
e

vasive action. &

vated.
Function of Active Speed Limit Assist
If a c
hange in the speed limit of 20 km/h or more
is detected and automatic adoption of speed lim-
its is activated, the new speed limit is automati-
cally adopted as the stored speed (  page 255).
The driven speed is adjusted when the vehicle is
level with the traPc sign at the latest. In the case
of signs indicating entry into an urban area, the
speed is adapted according to the speed permit-
ted within the urban area. The speed limit display
in the driver's display is always updated when the
vehicle is level with the traPc sign.
If you are driving on German motorways and there
is no speed limit, the system uses the speed
stored for a stretch of road with no speed limit as
the set speed. If you do not alter the stored speed
on a stretch of road with no speed limit, the rec-
ommended speed of 130 km/h is adopted.
If Active Distance Assist DISTRONIC has been put
into passive mode by pressing the accelerator pedal, only speed limits which are higher than the
se

t speed are adopted.
The maximum permissible speed does not take
the road condition and current weather and traPc
conditions into account. Adjust your speed
accordingly, when necessary.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (  page 236).
System limits
The system limits of TraPc Sign Assist apply to
the detection of traPc signs ( page 270).
Speed limits below 20 km/h are not automatically
adopted by the system as the stored speed. Tem-
porary speed restrictions (e.g. for a certain time
or due to weather conditions) cannot be properly
detected by the system. The maximum permissi-
ble speed applying to a vehicle with a trailer is not
detected by the system.
Adjust the speed in these situations. &
WARNING Risk of accident due t o Active
Speed Limit Assist adapting the vehicle's
speed
The speed adopted by Active Speed Limit
Assis
t may be too high or incorrect in some
individual cases, such as:
= at speed limits below 20 km/h
= in wet conditions or in fog
= when towing a trailer 
Ensure that the driven speed complies
wit

h traPc regulations. 
Adjust the driving speed to suit current
tr
aPc and weather conditions. Function of route-based speed adaptation
When A

ctive Distance Assist DISTRONIC is activa-
ted, the vehicle speed will be adapted accordingly
to the route events ahead. Depending on the drive
program selected, the vehicle negotiates a route
event ahead in a fuel-saving, comfortable or
dynamic manner. When the route event has been
passed, the vehicle accelerates again to the
stored speed. The set distance to the vehicle in Driving and parking
253

front, vehicles detected ahead and speed restric-
tions ahead ar
e taken into account.
Route-based speed adaptation can be activated in
the multimedia system ( page 255).
The following route events are taken into account:= Bends
= Roundabouts
= T-junctions
= Turns and exits
= TraPc jams ahead (only with Live TraPc )
Also, the speed is reduced if the turn signal indi-
cator is switched on and one of the following sit-
uations is detected:
= Turning at junctions
= Driving on slowing-down lanes
= Driving on lanes adjacent to slowing-down
lanes
The driver is responsible for choosing the right
speed and observing other road users. This
applies in particular to junctions, roundabouts and traPc
lights, as r oute-based speed adaptation
does not brake the vehicle to a standstill.
If a corresponding route event is detected while
route guidance is active, the Nrst speed adjust-
ment is carried out automatically. If the turn signal
indicator is switched on, the selected route is
conNrmed and further speed adjustment is activa-
ted.
Speed adaptation is cancelled in the following
cases:
= If the turn signal indicator is switched oM
before the route event and it is therefore
assumed that the route event is not relevant
to the driver.
= If the driver depresses the accelerator or
brake pedal during the process.
System limits
Route-based speed adaptation does not take right
of way regulations into account. The driver is
responsible for complying with road traPc regula-
tions and driving at a suitable speed. In diPcult
conditions, t he speed selection made
by the system may not always be suitable. This
applies to the following situations, forexample:
= the road's course not clearly visible
= Road narrowing
= varying maximum permissible speeds in indi-
vidual lanes, forexample at toll stations
= wet road surfaces, snow or ice
= If transport equipment, forexample a trailer or
bicycle rack, is attached to the trailer hitch
and the electrical connection has been cor-
rectly established.
In these situations the driver must intervene
accordingly. &

Function of Active Stop-and-Go Assist
A
ctive Stop-and-Go Assist helps you when in traf-
fic jams on multi-lane roads with separate carria-
geways by automatically pulling away within up to
60 seconds and with moderate steering manoeu-
vres. It orients itself using the vehicle in front and
lane markings. Active Stop-and-Go Assist auto- matically maintains a safe distance from the vehi-
cle in fr
ont and vehicles cutting in.
Active Stop-and-Go Assist requires you, as the
driver, to keep your hands on the steering wheel
at all times so that you are able to intervene at
any time to correct the course of the vehicle and
keep it in lane.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (  page 236).
Active Stop-and-Go Assist activates automatically
when all of the following conditions are met:
= You are in a traPc jam on a motorway or high-
speed major road.
= Active Distance Assist DISTRONIC is activated
and active (  page 250).
= Active Steering Assist is activated and active
( page 259).
= You are travelling no faster than 60 km/h.

System limits
The sy
stem limitations of Active Distance Assist
DISTRONIC and Active Steering Assist apply to
Active Stop-and-Go Assist ( page 257). DSR (Downhill Speed Regulation)
Function of DSR (Downhill Speed Regulation)
DSR is an aid t
o assist you when driving downhill.
It keeps the speed of travel at the selected target
speed. The steeper the downhill gradient, the
greater the D S R braking eMect on the vehicle.
On Oat stretches of road and uphill gradients, the
DSR brakes the vehicle minimally or not at all.
When DSR is activated and the transmission is in
position h, k or i, DSR controls the driving
speed. The target speed can be set to a value
between 2 km/h and 18 km/h. By braking or
accelerating, you can drive at a higher or lower
speed than the target speed at any time.
If you drive faster than 45 km/h or change the
driving programme (except in F/G), DSR
switches oM automatically. The î off message
appears in the driver's display. The status indica- tor in the driver's display goes out. You also hear
a w

arning tone.
Information on DSR &
WARNING Risk of skidding and accident
when DSR is activ
ated on slippery road
surfaces
If the driven speed and the target speed diMer
,
the wheels may lose traction. 
Take into account the road surface and
t
he diMerence between the driving speed
and target speed before activating DSR. Observe the notes on driving systems and your
r
esponsibility; you may otherwise fail to recognise
dangers ( page 236).
You are always responsible for keeping control of
the vehicle and for assessing whether the downhill
gradient can be negotiated. Depending on road
surface and tyres, DSR may not always be able to
keep to the target speed. Select a target speed
suitable for the environmental conditions and also
apply the brakes yourself if required. Activating or deactivating DSR (Downhill Speed
R

Requirements:
= You are driving at 40 km/h or slower.
If the vehicle speed is too high, the Max.

Function of Active Steering Assist
A
ctive Steering Assist is only available up to a
speed of 210 km/h. The system helps you to stay
in the centre of the lane by means of moderate
steering interventions. Depending on the speed
driven, Active Steering Assist uses the vehicles
ahead and lane markings as a reference. %
Depending on the country, in the lower speed
r
ange Active Steering Assist can use the sur-
rounding traPc as a reference. If necessary,
Active Steering Assist can then also provide
assistance when driving outside the centre of
the lane.
If the detection of lane markings and vehicles
ahead is im
paired, Active Steering Assist switches
to passive mode. The system provides no support
in this case.
