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.
qF
unction 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 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 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 256).
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. Driving and parking
255

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. &

tion or be t
emporarily unavailable in the fol-
lowing situations: =
If t

unction of Active Stop-and-Go Assist
Active 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 front and vehicles cutting in. 256
Driving and parking

Active Stop-and-Go Assist requires you, as the
dr iver, 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 237).
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 252).
= Active Steering Assist is activated and active
( page 260).
= You are travelling no faster than 60 km/h.

unction of Active Steering Assist
Active 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. 258

%
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.

The dr

iver 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
s

teered the vehicle for a considerable period of
time or has removed their hands from the steering
wheel, an optical warning is given Nrst. Display 1
appears in the driver's display. If the driver still
does not steer the vehicle, or gives no conNrma-
tion to the system, a warning tone sounds in addi-
tion to the visual warning message. If the driver does not react to this warning for a
consider
able period, an emergency stop is initi-
ated (  page 261).
The warning is not issued or is stopped as soon as
the system detects that the driver has touched
the steering wheel.
Touch detection may be limited or inoperative in
the following situations:
= The driver is wearing gloves.
= There is a steering wheel cover on the steering
wheel.
If Active Steering Assist detects that a system
limit has been reached, a visual warning is issued
and a warning tone sounds.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers ( page 237).
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. Driving and parking

The system may be impaired or may not function
in t
he following instances:
= There is poor visibility, e.g. due to snow, rain,
fog, heavy spray, greatly varying light condi-
tions or strong shadows on the carriageway.
= There is glare, e.g. from oncoming traPc,
direct sunlight or reOections.
= *nsuPcient road illumination.
= The windscreen is dirty, misted 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
junctions.
= The lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow.
= If the distance to the vehicle in front is too
short and thus the lane markings cannot be
detected.
= The road is narrow and winding.
= There are obstacles on the lane or projecting
out into the lane, suchas object markers. =
If tr ansport equipment, forexample a trailer or
bicycle rack, is attached to the trailer hitch
and the electrical connection has been cor-
rectly established.
The system does not provide assistance in the fol-
lowing conditions: = On very tight bends and when turning.
= When crossing junctions.
= At roundabouts or toll stations.
= When actively changing lane without switching
on the turn signal indicator.
= When the tyre pressure is too low. &

Function of Active Emergency Stop Assist
Active Emergency Stop Assist monitors the steer-
ing wheel and t
he accelerator and brake pedals. If
the system detects a lack of driver activity and the
vehicle threatens to leave the lane, a warning can
be issued and an emergency stop initiated.
Vehicles without Driving Assistance Package: The
system is available from a speed of approx.
60 km/h.
Vehicles with Driving Assistance package: If
Active Steering Assist is switched oM, the system
is available from a speed of approx. 60 km/h.
If the system detects that the vehicle is threaten-
ing to leave the lane, a warning can be issued and
an emergency stop initiated.
= The driver does not touch the steering wheel
for a longer period of time or no steering
movement can be measured for a longer
period of time (depending on the vehicle
equipment).
= Neither the accelerator nor the brake pedal is
depressed. %
Vehicles with Driving Assistance package: if
A
ctive Steering Assist is switched on and
active, only the steering wheel is monitored by
the system. If the driver does not touch the
steering wheel for a longer period of time, a
warning may be given despite pedal actuation.
Also observe the instructions on the contact
detection of Active Steering Assist
(  page 258). Active Emergency Stop Assist issues the following
w
arnings in order:
= Display message 1 appears in the driver's
display. =
In addition t
o display 1 a warning tone
sounds.
= The message Beginning emergency stop will
appear in the driver's display, a continuous
warning tone will sound, the vehicle will no
longer accelerate and, if necessary, slight belt
tensioning will be produced.
= The vehicle speed is reduced in increments
until it is at a standstill. Sharp brake impulses
are also produced.
% Vehicles with Driving Assistance Package: If
A
ctive Distance Assist DISTRONIC is active
and the driver unfastens the seat belt and
driver's door, an emergency stop can be initi-
ated immediately.
Vehicles with Driving Assistance Package:
Depending on t
he country, a lane change to the
adjacent right-hand lane is carried out, if possible.
It is only possible to change across one lane and
only into the right-hand lane, and not onto the
hard shoulder.
When automatic braking is initiated, Active Dis-
tance Assist DISTRONIC is deactivated. Depend- Driving and parking
