=In parking garages or on roads with steep
uphill or downhill gradients.
= If there are narrow vehicles in front, such as
bicycles or motorcycles.
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.
Operating Active Distance Assist DISTRONIC
Requirements: = The electric parking brake is released.
= ESP n
is activated and is not intervening.

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.Select O with the les rocker switch.\bIf you brake, deactivate ESP n
or if ESP n
inter-
venes, Active Distance Assist DISTRONIC is
deactivated.Increasing or decreasing the speed 1 mph (1 km/h): press rocker switch 1 up
M or down N to the pressure point.
or
5 mph (10 km/h): press rocker switch 1 up
M or down N beyond the pressure
point.
or
Accelerate the vehicle to the desired speed
and press rocker switch 1 up M .
Changing the speciNed distance to the vehicle in
front
To reduce the speciNed distance: press the
right rocker switch up ( Ñ).To increase the speciNed distance: press the
right rocker switch down ( Ò).
Function of Active Speed Limit Assist
If a change in the speed limit of 12 mph
(20 km/h) or more is detected and automatic
adoption of speed limits is activated, the new speed limit is automatically adopted as the storedspeed ( page 241).
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 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 thestored 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 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 211).226Driving and parking

System limits
The system limits of TraPc Sign Assist apply to
the detection of traPc signs ( page 240).
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.
Function 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 228).
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, 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 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:
= 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
= when towing a trailer
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.

When the function is active, the vehicle speed is adjusted depending on the route events

Function of Active Stop-and-Go Assist
Active Stop-and-Go Assist helps you when in traf- fic 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-
