RNING
The windscree nwill not longer be wiped prop-
erly if the wiper blades are worn .This could
prevent you from observing the traffic condi-
tions, thereby causing an accident .Replace the wiper blades twic
eayear, ideally in spring
and autumn.
! Do not operate the windscreen wipers
when the windscreen is dry, as this could
damage the wiper blades. Moreover ,dust
that has collected on the windscreen can
scratc hthe glass if wipin gtakes place when
the windscreen is dry.
If it is necessary to switch on the wind-
screen wipers in dry weather conditions,
always operate them using washe rfluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
windscreen with washer fluid after an auto-
matic car wash.
! Intermit tentwiping with rain sensor: due
to optical influences and the windscreen
becoming dirty in dry weather conditions,
the windscreen wipers may be activated
inadvertently. This could damage the wind-
screen wiper blades or scratc hthe wind-
screen.
For this reason, you should always switch
off the windscreen wiper sind ry weather. Combinatio

WARNING
DISTRONIC PLUS canno ttake account of road

recognise or no longer recognises the vehicle
in front, do not activate DISTRONIC or, if it is
alr eady active, deactivate it. This is especially
the case:
R befor ecorners
R on filter lanes
R when changing to alane with faster moving
traffic
R in comple xdriving situations or where lanes
are diverte d,e.g. at roadworks on amotor-
way
DISTRONIC PLU Sotherwise maintains the
current spe ed setbyyou or accelerates up to
the set speed.
DISTRONIC PLU Scannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONI CPLUS:
R if th eroads are slippery, snow-covered or
icy .The wheels coul dlose their grip when
brakin goraccelerating .The vehicle could
star ttos kid.
R if the sensors are dirty or there is poo rvis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLU Sisactivate d.
Otherwise, you ma yfail to recognise dangers
in time, caus eanaccident and injure yourself
and others. G
WARNING
DISTRONIC PLUS brake syourvehicle up to a
maximu mof4m /s2
depending on its speed.
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must als oapply the brakes yourself if this
braking power is not sufficient.
If DISTRONI CPLUS detect sarisk of collision
with avehicle in front, an intermit tent warning
tone sounds. In addition, the ·distance
warning lamp in the instrument cluste rlights
up. Brak etoavoidac ollision. G
WAR
NING
The vehicle can be braked when DISTRONIC
PLUS is activated. For this reason, deactivate
DISTRONIC PLUS if the vehicle is to be set in
motion by othe rmeans (e.g. in acar wash or
by towing).
The radar senso rsystem is switched off auto-
matically in the vicinity of radio teles cope
facilities (Y page 433).
If you want DISTRONIC PLUS to assist you,
the radar sensor syste mmust be activated
(Y page 283 )and operational.
General notes DISTRONIC PLUS regulates the speed and
automati
cally helps you maintain the dis-
tanc etot he vehicle detected in front. DI S-
TRONIC PLU Sbrake sautomatically so that
the set spee disnot exceeded.
On long and steep downhil lgradients, espe-
ciall yifthe vehicle is laden or towing atrailer,
yo um ust select shift range 1,2or 3in good
time. By doing so, you will make use of the
braking effec tofthe engine. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
If DI STRONIC PLUS detects aslower-moving
vehicle in front ,your vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
If ther eisnov ehicle in front ,DISTRONIC

WARNING
Active Parkin gAssist is merely an aid and may
sometimes recommen dparking spaces that
are not suitable for parking. For example,
these might be spaces where parking is pro-
hibited ,driveways, unsuitabl esurfaces, etc.
Active Parking Assis tmeasures the parking
space as you driv epast it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when the vehicle parked in front of or behind
the space changes its positio norwhen an
obstacle is moved int othe parkin gspace.
Active Parking Assist does not reliev eyou of
the responsibilit yofpaying attention. If you
rely solel yonA ctive Parkin gAssist, you could cause an acciden

You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings whe nparking and

WARNING
Objects located above the heigh trange of
Active Parking Assis twill not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e. g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some circumstances, Active Park-
ing Assist may therefor eguide you into the
parking space too early. This may lead to a
collision. For this reason, you should avoid
using Active Parking Assis tinsuch situations. Driving systems
