WARNING Risk of accident and injur y due
to the vehicle rolling away
Aser a shor
t time, Hill Start Assist no longer
holds the vehicle. 
Swisly mo
ve your foot from the brake
pedal to the accelerator pedal. Do not
leave the vehicle when it is being held by
Hill Start Assist. Function of Adaptive Brake Lights
Adaptive Brake Lights warn following
tr
aPc in an
emergency braking situation with the following
actions:
= Oashing the brake lamps
= activating the hazard warning lights
( page 146)
If the vehicle is braked sharply from speeds above
50 km/h, the brake lamps Oash rapidly. This pro-
vides traPc travelling behind you with an even
more noticeable warning. Start-oM
assist Function of the s

tart-oM assist
The start-oM assist enables optimal vehicle accel-
eration from a standstill. For this, a suitably high-
grip road surface is required, the tyres and vehicle
must also be in good condition.
Do not activate the start-oM assist on public
roads.
Be sure to observe the safety notes and informa-
tion on ESP n
( page 203).

WARNING Risk of skidding and ha
ving an
accident from wheels spinning
When you use s
tart-oM assist, individual
wheels could spin and you could lose control
of the vehicle.
If ESP n
is deactivated, there is a risk of skid-
ding and accident! 
Make sure that no persons or obstacles
ar
e in the close vicinity of your vehicle. 
Deactivating ESP n
( pag
e 206). 
Move the steering wheel to the straight-ahead
position. 
Depress the brake pedal Nr
mly with your les
foot and keep it depressed. 
Engage the h dr
ive position ( page 185). 
Select the sportiest available drive program
B or C(  pag

Take your foot oM t
he brake, but keep the
accelerator pedal depressed.
The vehicle pulls away at maximum accelera-
tion. 
Switch on ESP n
once t
he acceleration proce-
dure is complete. ESP n
will otherwise not be
able to stabilise the vehicle if the vehicle
starts to skid or a wheel starts to spin.

Driving and parking

ATTENTION ASSIST
Function of ATTENTION ASSIST
A
TTENTION 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
209

=
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 221).
= 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). Setting ATTENTION ASSIST

Function of cruise control
Cr

uise 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 201).

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
Function 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:
= V
ariable: 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 201).

Information on the permanent limiter
If t
he vehicle should never exceed a speciNc
speed (e.g. for driving in winter tyre mode), you
can set this speed with the permanent limiter.
You do this by limiting the speed between
160 km/h and 240 km/h in the multimedia sys-
tem ( page 213).
Shortly before the set speed is reached, it
appears in the Instrument Display. When you con-
Nrm the message, display messages no longer
appear until you switch oM the vehicle. The speed
will only be displayed again once the vehicle has
been restarted or if the set speed is changed.
The permanent limiter does not switch to passive
mode even during kickdown and the driven speed
remains below the set speed. Setting the limit speed for winter tyres

Function of Active Distance Assist DISTRONIC
DIS
TRONIC 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

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.
