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. 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. 218

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
b
y 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 n
is deactivated if the

ETS/4ETS can improve the vehicle's traction by
int
ervening in the following ways:
= The drive wheels are braked individually if they
spin.
= More drive torque is transferred to the wheel
or wheels with traction.
*nOuence of drive programs on ESP n
The drive programs enable ESP n
to adapt to dif-
ferent weather and road conditions as well as the
driver's preferred driving style. Depending on the
selected drive program, the appropriate ESP n
mode will be activated. You can select the drive
programs using the DYNAMIC SELECT switch

and weather conditions
In poor road and weather conditions, the
tr
ailer stabilisation cannot prevent lurching of
the vehicle/trailer combination. Trailers with a
high centre of gravity may tip over before
ESP n
detects this. 
Always adapt your driving style to suit
t

he current road and weather conditions. When driving with a trailer, ESP
n
can s
tabilise
your vehicle if the trailer begins to swerve from
side to side:
= ESP n
trailer stabilisation is active above
speeds of 65 km/h.
= Slight swerving is reduced by means of a tar-
geted, individual brake application on one
side. =
In t
he event of severe swerving, the operating
energy output is also reduced and all wheels
are braked.

. 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
f
atigue 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
break 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 your 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.224
Driving and parking

If a warning is given in the Instrument Display, the
multimedia sy stem 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 the 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 A ctive Steering Assist is activated and active
( page 235).
= 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).
