ATTENTION ASSIST

qFunction of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monoto-
nous journeys, e.g. on motorways and trunk
roads. If ATTENTION ASSIST detects indicators of
fatigue or increasing lapses in concentration on
the part of the driver, it suggests taking a break.
ATTENTION ASSIST is only an aid. It cannot
always detect fatigue or lapses in concentration in
time. The system is not a substitute for a well-res-
ted and attentive driver. On long journeys, take
regular breaks in good time that allow for ade-
quate recuperation.
You can choose between two settings:
= Standard: normal system sensitivity.
= Sensitive: higher system sensitivity. The driver
is warned earlier and the attention level detec-
ted by ATTENTION ASSIST is adapted accord-
ingly.
If drowsiness or increasing lapses in concentra-
tion are detected, the ATTENTION ASSIST Take
a break! warning appears in the Instrument Dis-
play. You can acknowledge the message and take a break where necessary. If you do not take a
br
eak and ATTENTION ASSIST continues to detect
increasing lapses in concentration, you will be
warned again aser a minimum of 15 minutes. You can have the following status information for
A

TTENTION ASSIST displayed in the assistance
menu of the on-board computer:
= The length of the journey since the last break.
= The attention level determined by ATTENTION
ASSIST:
- the fuller the circle, the higher the atten-
tion level determined -
as y
our attention wanes, the circle in the
centre of the display becomes smaller
If ATTENTION ASSIST is unable to calculate the
attention level and cannot issue a warning, the
System suspended message appears.
If a warning is given in the Instrument Display, the
multimedia system oMers to search for a rest
area. You can select a rest area and start naviga-
tion to this rest area. This function can be activa-
ted and deactivated in the multimedia system.
If ATTENTION ASSIST is deactivated, the Û
symbol appears in the assistance graphic in the
Instrument Display. Aser the vehicle is started,
ATTENTION ASSIST is automatically activated. The
last selected sensitivity level remains stored.
System limits
ATTENTION ASSIST is active in the 60 km/h to
200 km/h speed range.
Particularly in the following situations, ATTENTION
ASSIST only functions in a restricted manner and
warnings may be delayed or not occur:
= If you have been driving for less than approx-
imately 30 minutes. Driving and parking

=
If t he road condition is poor (uneven road sur-
face or potholes).
= If there is a strong side wind.
= If you adopt a sporty driving style (high corner-
ing speeds or high rates of acceleration).
= If Active Steering Assist is activated and active
( page 201).
= If the time has been set incorrectly.
= If you change lanes and vary your speed fre-
quently in active driving situations.
The ATTENTION ASSIST drowsiness or alertness
assessment is reset and restarted when continu-
ing the journey in the following situations:
= If you switch oM the vehicle.
= If you unfasten your seat belt and open the
driver's door (e.g. to change drivers or take a
break).

qF
unction of cruise control
Cruise control regulates the speed to the value
selected by the driver.
If you accelerate to overtake, forexample, the
stored speed is not deleted. If you remove your foot from the accelerator pedal
aser o
vertaking,
cruise control will resume speed regulation back
to the stored speed.
You can store any speed above 20 km/h up to the
maximum design speed or up to the set winter
tyre limit.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (  page 182).

System limits
Cr
uise control may be unable to maintain the
stored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lower gear in good time on long and
steep downhill gradients. Take particular note of
this when driving a laden vehicle. By doing so, you
will make use of the engine's braking eMect. This
relieves the load on the brake system and pre-
vents the brakes from overheating and wearing
too quickly.
Do not use cruise control in the following situa-
tions:
= in traPc situations which require frequent
changes of speed, e.g. in heavy traPc, on
winding roads
= on slippery roads. Accelerating can cause the
drive wheels to lose traction and the vehicle
could then skid.
= when visibility is poor
qFunction of the limiter
The limiter restricts the speed of the vehicle. To
reduce the speed to the set speed, the limiter
applies the brakes automatically.
You can limit the speed as follows:
= Variable: for a short-term speed restriction,
e.g. in built-up areas
= Permanent: for a longer-term speed restric-
tion, e.g. in winter tyre mode
You can store any speed above 20 km/h up to the
maximum design speed or up to the set winter
tyre limit. You can also perform settings while the
vehicle is stationary if the vehicle has been star-
ted.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers ( page 182).

qF
unction 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:
20 km/h - 200 km/h
= Vehicles with Driving Assistance Package:
20 km/h - 210 km/h Other features of Active Distance Assist
DIS

TRONIC:
= 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)
- Takes one-sided overtaking restrictions
into account on motorways or on multi-
lane roads with separate carriageways
(country-dependent)
Vehicles with Driving Assistance Package and
Parking Package: if the vehicle has been braked to
a standstill on multi-lane, separate carriageways
by Active Distance Assist DISTRONIC, it can auto-
matically follow the vehicle in front when driving
oM again within 30 seconds. If a critical situation
is detected when driving oM, a visual and acoustic
warning is given indicating that the driver must now take control of the vehicle. The vehicle is not
acceler ated any further.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (  page 182).

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. &
WARNING Risk of accident if de

function of Active Distance Assist
DISTRONIC is impaired
Active Distance Assist DISTRONIC does not
r
eact 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 tr
aPc conditions
carefully and react accordingly.
