Driving systems and your responsibility
Your vehicle is equipped with driving systems
whic
h assist you in driving, parking and manoeu-
vring the vehicle. The driving systems are only
aids. They are not a substitute for you paying
attention to your surroundings and do not relieve
you of your responsibility pertaining to road traPc
law. The driver is always responsible for maintain-
ing a safe distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for staying
in lane. Pay attention to the traPc conditions at
all times and intervene when necessary. Be aware
of the limitations regarding the safe use of these
systems.
Driving systems can neither reduce the risk of
accident if you fail to adapt your driving style nor
override the laws of physics. They cannot always
take into account road, weather or traPc condi-
tions. 228

WARNING Risk of accident due t
o restric-
ted detection performance of vehicle sen-
sors and cameras
If the area around vehicle sensors or cameras
is co
vered, damaged or dirty, certain driving
and safety systems cannot function correctly.
There is a risk of an accident. 
Keep the area around vehicle sensors or
camer

as clear of any obstructions and
clean. 
Have damage to the bumper, radiator
g

rille or stone chipping in the area of the
front and rear windows repaired at a
qualiNed specialist workshop. Particularly, keep the areas around the sensors
and camer
as free of dirt, ice or slush
(  page 356). The sensors and cameras must not be covered and the detection ranges around
t
hem must be kept free. Do not attach additional
licence plate brackets, advertisements, stickers,
foils or foils to protect against stone chippings in
the detection range of the sensors and cameras.
Make sure that there are no overhanging loads
protruding into the detection range.
If there is damage to a bumper or the radiator
grille, or aser an impact, have the function of the
sensors checked at a qualiNed specialist work-
shop. Have damage or stone chipping in the area
of the cameras on the front and rear windows
repaired at a qualiNed specialist workshop. Overview of driving systems and driving safety

The Anti-lock Brake System (ABS) regulates the
br

ake pressure in critical driving situations:
= During braking, for instance, at maximum full-
stop braking or if there is insuPcient tyre trac-
tion, the wheels are prevented from locking.
= Vehicle steerability while braking is ensured.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road con-
ditions and can serve as a reminder to take extra
care while driving.
System limits
= ABS is active from speeds of approx. 5 km/h.
= ABS may be impaired or may not function if a
malfunction has occurred and the yellow %
ABS warning lamp lights up continuously aser
the vehicle is started. 230

Function of BAS
&
WARNING Risk of an accident caused b y a
malfunction in BAS (Brake Assist System)
If BAS is malfunctioning, the braking distance
in an emer
gency braking situation is
increased. 
Depress the brake pedal with full force in
emer

gency braking situations. ABS pre-
vents the wheels from locking. The Brake Assist System (BAS) supports your
emer
gency braking situation with additional brake
force.
If you depress the brake pedal quickly, BAS is
activated:
= BAS automatically boosts the brake pressure.
= BAS can shorten the braking distance.
= ABS prevents the wheels from locking.
The brakes will function as usual once you release
the brake pedal. BAS is deactivated. Functions of ESP

or and improve driving stability and traction in
the following situations within physical limits:
= When pulling away on wet or slippery carriage-
ways.
= When braking.
If the vehicle deviates from the direction desired
by the driver, ESP n
can stabilise the vehicle by
intervening in the following ways:
= One or more wheels are braked.
= The engine output is adapted according to the
situation. ESP

HOLD function being active when you
leave the vehicle
If the vehicle is only braked with the HOLD
function it could, in t
he following situations,
roll away:
= If there is a malfunction in the system or in
the power supply.
= If the HOLD function is deactivated by
depressing the accelerator pedal or brake
pedal, e.g. by a vehicle occupant. 
Always secure the vehicle against rolling
a
way before you leave it. Requirements:
= The v

ehicle is stationary.
= The driver's door is closed or the seat belt on
the driver's side is fastened. =
The v
ehicle has been started or has been
automatically switched oM by the ECO start/
stop function.
= The electric parking brake is released.
= Active Distance Assist DISTRONIC is deactiva-
ted.
= The transmission is in position h, k or i.
(Vehicles with automatic transmission)
Activating the HOLD function 
Depress the brake pedal, and aser a shor
t
time quickly depress further until the

A horn sounds at regular intervals if, despite the
Brake immediately messag
e, you switch oM the
vehicle, remove your seat belt and open the driv-
er's door. If you attempt to lock the vehicle, the
horn tone becomes louder. The vehicle cannot be
locked until you have deactivated the HOLD func-
tion.
% Once you have switched oM t
he vehicle, you
cannot restart it until you have deactivated
the HOLD function. Function of Hill Start Assist
Hill Start Assist holds the vehicle for a short time
when pulling a

way on a hill under the following
conditions:
= The transmission is in position h or k.
(Vehicles with automatic transmission)
= The electric parking brake is released.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll away. &
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 145)
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 231).

. 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 236
Driving and parking

-
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. =
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 247).
= 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
