Never tamper with the wiring as well as
electronic components or their software. You
shouldh ave all work to electrical and
electronic equipment carried out at aqualified
specialist workshop.
! There is arisk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on ahigh
curb or an unpaved road
R you drive too fast over an obstacle, e.g.
ac urb or ahole in the road
R ah eavy object strikes the undercarriage
or parts of the chassis.
In situations like this, the body,t he
undercarriage, chassis parts, wheelsor
tires could be damaged withoutt he
damage being visible. Components
damaged in this way can unexpectedly fail
or, in the case of an accident, no longer
withstand the strain they are designed to.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody paneling. If
these materials come in contact with hot
parts of the exhaust system for an
extended period, they can catch fire.
Have the vehicle checked and repaired
immediately at aqualified specialist
workshop. If on continuing your journey
you noticet hat driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic
conditions. In such cases, visit aqualified
specialist workshop. Declarations of conformity

Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
(Y page 66)
R BAS ( Brake Assist System) (Y page 67)
R BAS PLUS ( BrakeAssist System Plus)
(Y page 67)
R ESP ®
(Electronic StabilityProgram)
(Y page 68)
R EBD ( Electronic Brake force Distribution)
(Y page 71)
R ADAPTIVE BRAKE (Y page 72)
R PRE-SAFE ®
Brake (Y page 72) Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
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,f
or vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road, weather and traffic
conditionsa nd maintain asafe distanc efrom
th ev ehicle in front. Drive carefully.
i The driving safety systems describe donly
work as effectivel yaspossible when there
is adequat econtac tbetween th etires and
th er oad surface. Pleas epay special
attentio ntothenote sont ires,
recommende dminimu mtire tread depths,
etc .(Ypage 334).
In wintry drivin gconditions, always use
winter tires (M+S tires) and if necessary,
sno wchains. Only in this way will the
drivin gsafet ysystems described in this
section work as effectively as possible. ABS (Anti-lock Brakin
gSystem)
Important safety notes i
Observe the "Importan tsafet ynotes"
sectio n(Ypage 66). G
WARNING
If ABSisf aulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully.H ave ABS checked
immediately at aqualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 267) and
displaym essages which may be shown in the
instrument cluster (Y page 238).
ABS regulates brake pressure in such away
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking. 66
Driving safety systemsSafety

ADAPTIVE BRAKE
ADAPTIV EBRAKE enhance sbraking safety
and offers increased braking comfort .In
addition to th ebraking function ,ADAPT IVE
BRAKE also has th eHOLDf unction
(Y page 186) and hill start assist
(Y page 150). PRE-SAFE
®
Brake
Genera linformation i
Observ ethe "Importan tsafet ynotes"
sectio n(Ypage 66).
PRE-SAFE ®
Brak eiso nly available in vehicles
with DISTRONIC PLUS.
If PRE-SAFE ®
Brak eistoa id you, the radar
senso rsystem mus tbe:
R activated (Y page 232)
R operational
With the help of the radar sensor system,
PRE-SAFE ®
Brak ecan detec tobstacles that
are in fron tofyour vehicle for an extended
period of time.
PRE-SAFE ®
Brak ecan help you to minimize
the risk of acollision with avehicle ahead or
reduce the effects of such acollision. If PRE-
SAFE ®
Brak ehas detected arisk of collision,
you will be warned visually and acoustically
as well as by automatic braking. PRE-SAFE ®
Brak ecannot preven tacollision withou tyour
intervention.
At speeds of up to approximately 40 mph
(70 km/h) PRE-SAFE®
Brake can also detect
stationary objects. Examples of stationary
object sare stopped or parked vehicles.
Important safety notes G
WARNING
PRE-SAFE ®
Brake will initially brake your
vehicle by apartial application of the brakes
if ad anger of collision is detected. There may
be acollision unless you also brake. Automatic emergenc
ybraking cannot prevent
ac ollision. There is arisk of an accident.
Always apply the brakes yourself and try to
take evasive action. G
WARNING
PRE-SAFE ®
Brake cannot alwaysc learly
identify objects and comple xtraffic
conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R not give awarning or intervene
There is arisk of an accident.
Always pay particular attention to the traffic
situation and be read ytobrake, especially if
PRE-SAFE ®
Brake warns you.T erminate the
intervention in anon-critical driving situation.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else
covering the sensors
R snow or heavy rain
R interference by other rada rsources
R there are strongr adar reflections, for
example in parking garages
R an arrow vehicle traveling in front,e .g. a
motorbike
R av ehicle traveling in front on adifferent line
relative to the center of your vehicle G
WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossin gtraffic
R when cornering
As aresult, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical
situations. There is arisk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. 72

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please not ethat your vehicle may
not be equipped with all features
described. This also applies to safety-
related system sand functions.
i Read the information on qualified
specialist workshops: (Y page 26).Overview of climat
econtrol systems Important safet
ynotes
Observ ethe settings recommende donthe
following pages. The windows could
otherwise fog up.
To preven tthe windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air
dehumidification function
R switch on the defrost windshield 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 can only be operated when
the engine is running. Optimum operation is
only achieved with the side windows and roof
closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 141).
i Ventilate the vehicle for abrief period
during warm weather, e.g. using the
convenience opening feature (Y page 89).
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
particles of dust and soot and completely
filters out pollen. It also reduces gaseous
pollutantsa nd odors.Aclogged filter
reduces the amoun tofair supplied to the
vehicle interior .For this reason, you should
always observe the interval for replacing
the filter, which is specified in the
Maintenance Booklet .Asitdepends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet. 130
