Driving safety systems overview
In this section, you will find information about the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
(Y page 60)
R BAS ( Brake Assist System) (Y page 61)
R BAS PLUS ( BrakeAssist System PLUS)
(Y page 61)
R Adaptive brake lamps (Y page 62)
R ESP ®
(Electronic StabilityProgram)
(Y page 62)
R EBD ( electronic brake force distribution)
(Y page 66)
R ADAPTIVE BRAKE (Y page 66)
R PRE-SAFE ®
Brake (Y page 66) Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can neither 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 the distance
to the vehicle in front, for vehicle speed and
for braking in good time. Always adapt your
driving style to suit the prevailing road and
weather conditions and maintain a safe dis-
tance from the vehicle in front. Drive care-
fully.
i The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tyres and the road surface. Please pay special atten-tion to the notes on tyres, recommended
minimum tyre tread depths etc.
(Y page 314). In wintry driving conditions, always use
winter tyres (M+S tyres) and, if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively 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 vehi-
cle when braking.
The yellow !ABS warning lamp in the
instrument cluster lights up when the ignition is switched on. It goes out when the engine is
running.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 60). 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,
including driving safety systems, will also
become inoperative. Observe the information on the ABS warning lamp (Y page 252) and
display messages which may be shown in the
instrument cluster (Y page 223).
ABS works from a speed of about
8 km/hupwards, regardless of road-surface
conditions. ABS works on slippery surfaces,
even when you only brake gently. 60
Driving safety systemsSafety

In these cases, PRE-SAFE
®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE ®
Brake warns you. Terminate the
intervention in a non-critical driving situation.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col- lision, you must apply the brakes yourself. G
WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In the event of snowfall or heavy rain, detec-
tion can be impaired.
Detection by the radar sensor system is also
impaired in the event of:
R dirt on the sensors or obscured sensors
R interference by other radar sources
R strong radar reflections, for example, in
multi-storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different
line
Following damage to the front end of the vehi-
cle, have the radar sensor settings and oper- ation checked at a qualified specialist work-
shop. This also applies to collisions at slow
speeds where there is no visible damage to
the front of the vehicle. Function X
To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 211).
Vehicles with a black and white multi-
function display: when PRE-SAFE®
Brake
is activated, the Äsymbol appears in
the status overview in the multifunction
display.
Vehicles with a colour multifunction
display: when PRE-SAFE ®
Brake is deacti-
vated, the æsymbol appears in the
assistance graphic in the multifunction dis- play.
This function will issue a warning if:
R at a speed of approximately 30 km/h or
higher, the distance maintained to the vehi-
cle travelling in front is insufficient for sev-
eral seconds.
The · distance warning lamp then lights
up in the instrument cluster.
R at a speed of approximately 7 km/h or
higher, you rapidly approach a vehicle in
front.
An intermittent warning tone will then
sound and the ·distance warning lamp
will light up in the instrument cluster.
X Brake immediately to defuse the situation.
or X Take evasive action provided it is safe to do
so.
The PRE-SAFE ®
Brake function can also brake
the vehicle automatically under the following
conditions:
R the driver and front passenger have their
seat belts fastened
and
R the vehicle speed is between approx-
imately 7 km/h and 200 km/h
Up to a speed of approximately 70 km/h,
PRE-SAFE ®
Brake can also detect stationary
objects. Examples of stationary objects are
stopped or parked vehicles. Driving safety systems

General notes
Observe the settings recommended on the
following pages. The windows could other-
wise mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the "demist windscreen" function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. Optimum operation is only
achieved when the side windows and the roof
are closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 135).
i Ventilate the vehicle for a brief period
during warm weather. This will speed up the
cooling process, and the desired vehicle
interior temperature will be reached more
quickly. i
The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants and odours. A clogged filter reduces the amount of air supplied to the vehicle
interior. For this reason, you should alwaysobserve the interval for replacing the filter,
which is specified in the Service Booklet. As this depends on environmental conditions,
e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet. 126

Only use the "Windscreen demisting" func-
tion briefly until the windscreen is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odours or
when in a tunnel. The windows could oth-
erwise mist up as no fresh air is drawn into
the vehicle in air-recirculation mode.
