EBD ( electronic brake force distribution)
(Y page 60)
R ADAPTIVE BRAKE (Y page 60)Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front, for vehicle speed, for braking in
good time, and for staying in lane. Always adapt
your driving style to suit the prevailing road and weather conditions and maintain a safe distancefrom the vehicle in front. Drive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tyres and the road
surface. Please pay special attention to the
notes on tyres, recommended minimum tyre
tread depths etc. (Y page 261).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. ABS (Anti-lock Braking System)
General notes ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 8 km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 54). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems, includ-
ing driving safety systems, will also become
inoperative. Observe the information on the ABS warning lamp (Y page 197) and display mes-
sages which may be shown in the instrument
cluster (Y page 172).
Braking X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application: depress
the brake pedal with full force.
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 conditions; this serves as a
reminder to take extra care while driving. BAS (Brake Assist System)
General notes BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 54). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of accident. 54
Driving safety systemsSafety

accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again. X
Briefly pull the cruise control lever towards
you :.
X Remove your foot from the accelerator pedal.
DISTRONIC PLUS is activated. The first time it
is activated, the current speed is stored. Oth-
erwise, it sets the vehicle cruise speed to the
previously stored value.
Driving with DISTRONIC PLUS Pulling away and driving X
If you want to pull away with DISTRONIC
PLUS:
remove your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you :.
or X Accelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to
the set speed.
i The vehicle can also pull away when it is
facing an unidentified obstacle or is driving on
a different line from another vehicle. The vehi-
cle then brakes automatically. There is a risk
of an accident. Be ready to brake at all times.
If there is no vehicle in front, DISTRONIC PLUS
operates in the same way as cruise control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes your vehicle. In
this way, the distance you have selected is main-
tained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up to
the speed you have stored.
Selecting the drive program
DISTRONIC PLUS assists a sporty driving style
when you have selected the Sor S+ drive pro-
gram (see the vehicle Owner's Manual). Accel-
eration behind the vehicle in front or to the set
speed is then noticeably more dynamic. When
you select the Cdrive program, the vehicle
accelerates more gently. This setting is recom-
mended in stop-start traffic.
Changing lanes
If you change to the overtaking lane, DISTRONIC
PLUS supports you if:
R you are driving at a speed greater than
70 km/h
R you switch on the respective turn signal
R DISTRONIC PLUS does not detect a danger of
collision
If these conditions are met, your vehicle accel-
erates. Acceleration will be interrupted if chang- ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.

General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect them at all. The system is not a substitute for a well-rested and
attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or not
occur at all in the following situations:
R the length of the journey is less than approx-
imately 30 minutes
R if the road condition is poor, e.g. if the surface
is uneven or contains potholes
R in the event of strong crosswinds
R if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h
R if the time has been set incorrectly
R in active driving situations, such as when you
change lanes or change your speed
The ATTENTION ASSIST tiredness assessment
is deleted and restarted when you continue the journey in the following situations:
R you switch off the engine
R you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break Driving systems

top of the windscreen. The data and general
traffic regulations stored in the navigation sys-
tem are also used to determine the current
speed limit.
If a traffic sign that is relevant to your vehicle is passed, the display of the speed limits and over-
taking restrictions is updated.
The display can also be updated without a visible traffic sign if:
R the vehicle changes roads (e.g. motorway exit
or slip road)
R a village or town boundary is passed which is
stored in the digital map
R the last traffic sign detected by the camera
has not been repeated
If a sign indicating the end of a restriction (speed limit or overtaking restriction) is passed, the
sign is displayed for five seconds. The currently
applicable traffic regulation continues to be
shown in the assistance graphic display
(Y page 163).
The camera also detects traffic signs with a
restriction indicated by an additional sign (e.g. in wet conditions).
The traffic signs are only displayed with the
restrictions if:
R the regulation must be observed with the
restriction, or
R Traffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the avail- able sources, no speed limit is displayed in the
instrument cluster either. Traffic Sign Assist is not available in all coun-
tries. In this case, symbol :is shown in the
assistance graphic display (Y page 163).Important safety notes Traffic Sign Assist is only an aid and is not always
able to correctly display speed limits and over-
taking restrictions. Traffic signs always have pri-
ority over the Traffic Sign Assist display.
The system may be either functionally impaired
or temporarily unavailable if:
R visibility is poor, e.g. due to snow, rain, fog or
spray
R there is glare, e.g. from the sun being low in
the sky
R there is dirt, ice or misting on the windscreen
in the vicinity of the camera
R traffic signs are hard to detect, e.g. due to dirt,
ice or snow
R the traffic signs are insufficiently lit at night
R signs are ambiguous, e.g. traffic signs on con-
struction sites or in adjacent lanes
R the information in the digital street map of the
navigation system is incorrect or out of date
Switching the message function on/off The Traffic Sign Assist message function can be
switched on in the on-board computer. When
you pass a traffic sign, traffic regulations (speed
limits and overtaking restrictions) are shown in
the multifunction display for five seconds. The
previous menu is then shown automatically.
The wrong-way warning and the traffic sign dis- play for speed limits and overtaking restrictionsremain active even when the display has been
deactivated.

The speed limit no longer applies
:.
i The unit for the speed limit (km/h or mph)
depends on the country in which you are driv-
ing. It is generally neither shown on the traffic
sign nor on the instrument cluster but must be
taken into account when observing the max-
imum permitted speed.
No entry (wrong-way warning) If no entry signs are passed, a warning message
is displayed in the instrument cluster should
Traffic Sign Assist detect that you are driving in the wrong direction. You will then also hear a
warning tone. You should immediately check
your direction of travel in order to avoid danger
to yourself and other road users.
i This function is not available in all countries. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 151) and Lane Keeping
Assist (Y page 153).
Blind Spot Assist General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the exterior mirrors
draws your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lanes, you will also receive a visual and audible collision warn-
ing. Blind Spot Assist supports you from a speed of
approximately 30 km/h.
Important safety notes G
WARNING
Blind Spot Assist does not react to vehicles:
R overtaken too closely on the side, placing
them in the blind spot area
R when the difference in the speed of
approach and overtaking is too great
As a result, Blind Spot Assist cannot warn
drivers in these situations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and maintain a safe distance at the side
of the vehicle.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles. Radar sensors
The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the bumpers are free from dirt, ice or slush. The
sensors must not be covered, for example by
cycle racks or overhanging loads. Following a
severe impact or in the event of damage to the
bumpers, have the function of the radar sensors
checked at a qualified specialist workshop.
Blind Spot Assist may no longer work properly.
Monitoring range In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or bicycles
R very wide lanes
R narrow lanes
R vehicles not driving in the middle of their lane
R barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated. Driving systems
