Rthe vehicle becomes stuck, e.g. onahigh
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g.
acurb orahole in the road
Raheavy object strikes the undercarriage
or parts of the chassis.
In situations like this, the body,the
undercarriage, chassis parts, wheelsor
tires could be damaged withoutthe
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

Driving safety systems
Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
RABS (Anti-lockBrakingSystem)
(Ypage 66)
RBAS (BrakeAssistSystem) (Ypage 67)
RBAS PLUS (BrakeAssistSystem Plus)
(Ypage 67)
RESP®(ElectronicStabilityProgram)
(Ypage 68)
REBD (ElectronicBrake forceDistribution)
(Ypage 71)
RADAPTIVE BRAKE (Ypage 72)
RPRE-SAFE®Brake (Ypage 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,for vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road, weather and traffic
conditionsand maintainasafe distancefrom
thevehicle in front. Drive carefully.
iThe driving safety systems describedonly
work as effectivelyaspossible when there
is adequatecontactbetween thetires and
theroad surface. Pleasepay special
attentiontothenotesontires,
recommendedminimumtire tread depths,
etc.(Ypage 334).
In wintry drivingconditions, always use
winter tires (M+S tires) and if necessary,
snowchains. Only in this way will the
drivingsafetysystems described in this
section work as effectively as possible.
ABS (Anti-lock BrakingSystem)
Important safety notes
iObserve the "Importantsafetynotes"
section(Ypage 66).
GWARNING
If ABSisfaulty, 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.Have ABS checked
immediately ataqualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Ypage 267) and
displaymessages which may be shown in the
instrument cluster (Ypage 238).
ABS regulates brake pressure in suchaway
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.

ADAPTIVE BRAKE
ADAPTIVEBRAKE enhancesbraking safety
and offers increased braking comfort.In
addition to thebraking function,ADAPTIVE
BRAKE also has theHOLDfunction
(Ypage 186) and hill start assist
(Ypage 150).
PRE-SAFE®Brake
Generalinformation
iObservethe"Importantsafetynotes"
section(Ypage 66).
PRE-SAFE®Brakeisonly available in vehicles
with DISTRONIC PLUS.
If PRE-SAFE®Brakeistoaid you, the radar
sensorsystem mustbe:
Ractivated (Ypage 232)
Roperational
With the help of the radar sensor system,
PRE-SAFE®Brakecan detectobstacles that
are in frontofyour vehicle for an extended
period of time.
PRE-SAFE®Brakecan help you to minimize
the risk ofacollision withavehicle ahead or
reduce the effects of suchacollision. If PRE-
SAFE®Brakehas detectedarisk of collision,
you will be warned visually and acoustically
as well as by automatic braking. PRE-SAFE®
Brakecannot preventacollision withoutyour
intervention.
At speeds of up to approximately 40 mph
(70 km/h)PRE-SAFE®Brake can also detect
stationary objects. Examples of stationary
objectsare stopped or parked vehicles.
Important safety notes
GWARNING
PRE-SAFE®Brake will initially brake your
vehicle byapartial application of the brakes
ifadanger of collision is detected. There may
beacollision unless you also brake.
Automatic emergencybraking cannot prevent
acollision. There isarisk of an accident.
Always apply the brakes yourself and try to
take evasive action.
GWARNING
PRE-SAFE®Brake cannot alwaysclearly
identify objects and complextraffic
conditions.
In these cases, PRE-SAFE®Brake may:
Rgive an unnecessary warning and then
brake the vehicle
Rnot giveawarning or intervene
There isarisk of an accident.
Always pay particular attention to the traffic
situation and be readytobrake, especially if
PRE-SAFE®Brake warns you.Terminate the
intervention inanon-critical driving situation.
In particular, the detection of obstacles can
be impaired if there is:
Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain
Rinterference by other radarsources
Rthere are strongradar reflections, for
example in parking garages
Ranarrow vehicle traveling in front,e.g. a
motorbike
Ravehicle traveling in front onadifferent line
relative to the center of your vehicle
GWARNING
PRE-SAFE®Brake does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossingtraffic
Rwhen cornering
Asaresult, PRE-SAFE®Brake may neither
give warnings nor intervene in all critical
situations. There isarisk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.

Useful information
iThis 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

Overview of climatecontrol systems
Important safetynotes
Observethe settings recommendedonthe
following pages. The windows could
otherwise fog up.
To preventthe windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only
briefly
Rswitch on the cooling with air
dehumidification function
Rswitch 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 (Ypage 141).
iVentilate the vehicle forabrief period
during warm weather, e.g. using the
convenience opening feature (Ypage 89).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
iThe integrated filter filters out most
particles of dust and soot and completely
filters out pollen. It also reduces gaseous
pollutantsand odors.Aclogged filter
reduces the amountofair 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.
