In addition, on slippery roads, braking or acceler- ating can cause one or several wheels to lose
traction and the vehicle could then skid.
Do not use Active Distance Assist DISTRONIC in these situations.&WARNING Risk of accident from accelera-
tion or braking by Active Distance Assist
DISTRONIC
Active Distance Assist DISTRONIC may accel-
erate 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 traPc con-
ditions and be ready to brake at all
times.Take into account the traPc situation
before calling up the stored speed.&WARNING Risk of accident due to insuP-
cient deceleration by Active Distance
Assist DISTRONIC
Active Distance Assist DISTRONIC brakes your vehicle 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 distance from the vehicle in front.Brake the vehicle yourself and/or take
evasive action.&WARNING Risk of accident if detection
function of Active Distance Assist DISTRONIC is impaired
Active Distance Assist DISTRONIC does not
react or has a limited reaction:
= when driving on a diMerent lane or when
changing lanes
= to pedestrians, animals, bicycles or sta-
tionary vehicles, or unexpected obstacles
= to complex traPc conditions
= to oncoming vehicles and crossing traPc
As a result, Active Distance Assist DISTRONIC may neither give warnings nor intervene in
such situations.
Always observe the traPc conditions
carefully and react accordingly.

Deactivating Active Distance Assist DISTRONIC
&WARNING Risk of an accident due to
Active Distance Assist DISTRONIC being
active when you leave the driver\bs seat
If you leave the driver\bs seat while the vehicle
is being braked by Active Distance Assist
DISTRONIC only, the vehicle can roll away.
Always deactivate Active Distance Assist
DISTRONIC and secure the vehicle to
prevent it from rolling away before you
leave the driver\bs seat.Press

If Active Distance Assist DISTRONIC has been put
into passive mode by pressing the accelerator pedal, only speed limits that are higher than the
set speed are adopted.
Observe the notes on driving systems and your responsibility; you may otherwise fail to recognizedangers (  page 170).
System limits
The system limits of TraPc Sign Assist apply to
the detection of traPc signs (  page 196).
Speed limits below 12 mph (20 km/h) are not
automatically adopted by the system as the stored speed. Temporary speed restrictions (e.g. for a
certain time or due to weather conditions) cannot
be properly detected by the system. The maxi- mum permissible speed applying to a vehicle witha trailer is not detected by the system.
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 186).
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
Driving and parking185

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, as route-based speed adaptation
does not brake the vehicle to a standstill.
When route guidance is active, the Nrst speed
adjustment is carried out automatically. If the turn signal indicator is switched on, the selected routeis 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:
= 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 limitationsAdapt the speed to the traPc situation.

qFunction of Active Stop-and-Go Assist
Active Stop-and-Go Assist helps you when in traf- Nc jams on multi-lane roads with separate road-
ways by automatically pulling away within up to
60 seconds and with moderate steering maneu-
vers. 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 front 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 sys- tems and your responsibility; you may otherwise
fail to recognize dangers (  page 170).
Active TraPc Jam Assist activates automatically as
soon as all of the requirements are met: The

=Ø (white, red hands): "hands on the steer-
ing wheel" prompt\bDuring the transition from active to passive
status, the Ø symbol is shown as enlarged
and Oashing. Once the system is passive, the
Ø symbol is shown as gray in the Instru-
ment Display.\bDepending on the selected vehicle settings,
Active Steering Assist may be unavailable.
Steering and touch detection
The driver is required to keep their hands on the steering wheel at all times and be able to inter-
vene at any time to correct the course of the vehi-
cle and keep it in lane. The driver must expect a change from active to passive mode or vice versa at any time.If the system detects that the driver has not
steered the vehicle for a considerable period of time or has removed their hands from the steeringwheel, display 1 appears. If the driver still does
not steer the vehicle, a warning tone sounds in
addition to the visual warning message.
If the driver does not react to the warning for a
considerable period, the system can initiate an
emergency stop (  page 189).
If the driver steers, no warning is issued, or the warning is ended.
If Active Steering Assist detects that a system limit has been reached, a visual warning is issuedand a warning tone sounds.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognize
dangers (  page 170).
System limits
Active Steering Assist has a limited steering tor-
que for lateral guidance. In some cases, the steer-
ing intervention is not suPcient to keep the vehi-
cle in the lane or to drive through exits.
The system may be impaired or may not function
in the following instances:
= There is poor visibility, e.g. due to snow, rain,
fog, heavy spray, greatly varying ambient light
or strong shadows on the road.
= There is glare, e.g. from oncoming traPc,
direct sunlight or reOections.
= *nsuPcient road illumination.
= The windshield is dirty, fogged up, damaged or
covered in the vicinity of the camera, e.g. by a
sticker.
= No, or several, unclear lane markings are pres-
ent for one lane, or the markings change
quickly, forexample, in a construction area or intersections.188Driving and parking
