Active Distance Assist DISTRONIC
q Function of Active Distance Assist DISTRONIC
DISTRONIC 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:
15 mph (20 km/h) - 120 mph (200 km/h)
= Vehicles with Driving Assistance Package:
15 mph (20 km/h) - 130 mph (210 km/h)
Other features of Active Distance Assist
DISTRONIC:
= Adjusts the driving style depending on the
selected drive program (fuel-saving, comforta-
ble or dynamic)
= 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)Driving and parking183

The driven speed is adjusted when the vehicle islevel 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 on the instrument display is always updated when the vehicle is level with the traPc sign.
If there is no speed restriction on an unlimited
stretch of road (e.g. on a freeway), the recom-
mended speed is automatically adopted as the stored speed. The system uses the speed stored
on an unlimited stretch of road as the recommen-
ded speed. If you do not alter the stored speed on
an unlimited stretch of road, the recommended
speed is 80 mph (130 km/h).
If Active Distance Assist DISTRONIC has been put
into passive mode by pressing the accelerator pedal, only speed limits which are higher than theset speed are adopted.
Observe the notes on driving systems and your responsibility; you may otherwise fail to recognizedangers ( page 172).System limits
The system limits of TraPc Sign Assist apply to
the detection of traPc signs ( page 200).
Speed limits below 12 mph (20 km/h) are not
automatically adopted by the system as the stored speed. Temporary speed restrictions (e.g. applica-
ble for a certain time or due to weather condi-
tions) cannot be properly detected by the system. The maximum permissible speed applying to avehicle with a trailer is not detected by the sys-tem.
Adjust the speed in these situations.&WARNING Risk of accident due to Active
Speed Limit Assist adapting the vehicle\bs
speed
The speed adopted by Active Speed Limit Assist may be too high or incorrect in some
individual cases, such as:
= at speed limits below 12 mph (20 km/h)
= in wet conditions or in fog
= when towing a trailer
Ensure that the driven speed complies
with traPc regulations.Adjust the driving speed to suit current
traPc and weather conditions.
qFunction of route-based speed adaptation
When Active 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 routeevent ahead in an economical, 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
front, vehicles detected ahead and speed restric-
tions ahead are taken into account.
You can activate and deactivate route-based
speed adaptation in the multimedia system ( page 189).
The following route events are taken into account: = Bends
= T-intersections, traPc circles and toll stations
= Turns and exits

=TraPc jams ahead (only with Live TraPc Infor-
mation )\bWhen the toll station is reached, Active Dis- tance Assist DISTRONIC adopts the speed asthe stored speed.
Also, the speed is reduced if the turn signal indi-
cator to change lanes is switched on and one of
the following situations is detected:
= Turning at intersections
= 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 intersections, traPc circles
and traPc lights because route-based speed
adaptation does not brake the vehicle to a stand-
still.
When route guidance is active, the Nrst speed
adjustment is carried out automatically. If the turn signal indicator is switched on, the selected route
is conNrmed and further speed adjustment is acti-
vated.
Speed adaptation is canceled in the following
cases:
= If the turn signal indicator is switched oM
before the route event.
= 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.
The speed adaptation made by the system may not always be suitable, particularly in the following
situations:
= the road\bs course not clearly visible
= Road narrowing
= varying maximum permissible speeds in indi-
vidual lanes, forexample at toll stations
= wet road surfaces, snow or ice
In these situations the driver must intervene accordingly.&WARNING Risk of accident in spite of
route-based speed adaptation
Route-based speed adaptation can malfunc-
tion or be temporarily unavailable in the fol-
lowing situations:
= If the driver does not follow the calculated
route
= If map data is not up-to-date or available
= In the event of roadworks
= In bad weather or road conditions
= If the accelerator pedal is depressed
= In the event of electronically displayed
speed limitations
Adapt the speed to the traPc situation.

DSR (Downhill Speed Regulation)
qFunction of DSR
DSR is an aid to assist you when driving downhill. It keeps the speed of travel at the selected target
speed. The steeper the downhill gradient, the greater the DSR 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 [, ^ or \\, DSR controls the driving
speed. The target speed can be set to a value
between 1 mph (2 km/h) and 11 mph (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 28 mph (45 km/h) or change the drive program (except in )), DSR
switches oM automatically. The î Off mes-
sage will then appear on the instrument display. The status indicator on the instrument display goes out. You also hear a warning tone.
q Information on DSR&WARNING Risk of skidding and accident
when DSR is activated 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
the diMerence between the driving speed
and target speed before activating DSR.
Observe the notes on driving systems and your responsibility; you may otherwise fail to recognizedangers ( page 172).
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 tires, 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.
q Activating or deactivating DSR (Downhill Speed
Regulation)
Requirements:
= You are driving at a speed of 25 mph
(40 km/h) or lower.
If the current vehicle speed is too high, the Max. Speed 24 mph message appears in the
multifunction display.
= Active Distance Assist DISTRONIC is deactiva-
ted.
