When the distan
cewarning function is acti-
vated, the multifunction display shows the
Ä symbol as long as the HOLD function is
not activated (Y page 211). On vehicles with
Active Parking Assist, the Äsymbol is dis-
played when position Pis engaged or you are
driving faster than 35 km/h.
The distanc ewarning function can help you
to minimise the risk of acollision with the
vehicle in fron torreduce the effects of such
ac ollision .Ifthe distanc ewarning function
detect sthat ther eisar isk of acollision ,you
will be warned visually and acoustically .The
distanc ewarning function cannot preven ta
collision without your inte rvention.
The distan cewarning function will issue a
warning at speed sofaround 30 km/h or
more if:
R thed istanc etothe vehicle in fron tist oo
short for the speed you ar edriving at for
severa lseconds. The ·distan cewarn-
ing lamp then lights up in the instrument
cluster.
R you are rapidly approaching the vehicle in
front. An intermittent warning ton ewill
then sound and the ·distanc ewarning
lamp will light up in the instrument cluster.
X Brak eimmediatel yinordertoi ncreas ethe
distanc efrom th evehicle in front.
or
X Take evasiv eactio nprovide ditiss afe to do
so.
For the distanc ewarning function to assist
you when driving, the function must be acti-
vated in the on-board computer and be opera-
tional (Y page 278).
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning.
With the help of the radar senso rsystem, the
distanc ewarning function can detect obsta-
cles that are in the path of your vehicle for an
extended period of time.
At speeds up to approximately 70 km/h, the
distance warning fun ction may also detect stationary obstacles, for example, stopped or
parked vehicles.
If you approach an obstacle and the distance
warnin gfunction detects arisk of acollision,
the system will initially aler tyou both visually
and acoustically.
In particular ,the detection of obstacles can
be impaired if ther eis:
R dir tont he sensors or anythin gelse cover-
ing the sensors
R snow or heavy rain
R interferenc ebyother radar sources
R the possibility of strong radar reflections,
for example, in multi-storey car parks
R an arro wvehicle travelling in front, e.g. a
motorcycle
R av ehicle travelling in fron tonadifferent
line
Following damage to the fron tend of the vehi-
cle ,havet he configuration and operation of
the radar sensor checked at aqualified spe-
cialist workshop. This also applie stoc olli-
sions at slow speeds where ther eisnovisible
damage to the fron tofthe vehicle.

WARNING
DISTRONIC PLUS canno ttake account of road
and traffic conditions. If DISTRONI Cdoes not
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
PLUS operate sinthe sam eway as cruise

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
tand injure yourself and oth-

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

Monitoring range of the sensors G
WARNING
Blind Spot Assist monitors certain areas in the
immediate vicinit yofyour vehicle. Vehicles
that approach and driv epast at high speeds
are not detected. There is no display and no
warning.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in astaggered formation in
different lanes .This ma ybethe case if vehi-
cles ar edriving at th eedge of their lane that
is furthest away from your vehicle.
Alway spay attention to traffic conditions and
your surroundings. Otherwise ,you may fai lto
recognis edangers in time, cause an accident
and injure yourself and others. Blind Spot Assis
tmonitors the area up to
3. 0mb ehind your vehicle and direc tlyn extto
your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles drivin gint he
lan ebeyond th elan en ext to your vehicle may
be indicated, especially if th evehicles are not
drivin gint he midd le of their lane. This may
be th ecase if there are vehicles at th eedge
of their lan eneares tyour vehicle.
Due to th enature of th esystem:
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R warnings may be interrupted when driving
alongside long vehicles, for example lor-
ries, for aprolonged time.
Th et wo radar sensors for Blin dSpot Assist
are integrated int othe sides of the rear
bumper .Make sure that the bumper is free of
dirt, ice or slush in the vicinity of the sensors.
The sensor smust not be covered, for exam-
ple by cycle racks or overhanging loads .Fol-
