PARKTRONIC
Important safety notes G
WARNING
PARKTRONIC is only an aid and may not
detect all obstacles. It is not asubstitute for
attentive driving.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visuallya nd
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically if
you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release the parking brake
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC monitorst he area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.
Range of the sensors General notes
!
When parking, pay particular attention to
objectsa bove or below the sensors, such
as flower pots or trailer drawbars. PARK-
TRONIC does not detect such objectsw hen
they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
The sensors may not detect snow and
objectsw hich absorb ultrasonic sources. Ultrasonic sources, such as an automatic
car wash,
alorry's compressed-air brakes
or ap neumatic drill, could cause PARK-
TRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain. :
Example: sensors in the front bumper,
left-han dside
The sensors must be free of dirt, ice and
slush. Otherwise, they may not function cor-
rectly. Cleant he sensors regularly,t aking

Important safety notes G
WARNING
Active Parking Assist is merely an aid and may
sometimes recommendp arking spaces that
are not suitable for parking. For example,
these might be spaces where parking is pro-
hibited, driveways, unsuitable surfaces, etc.
Active Parking Assist measures the parking
space as you drive past 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 position or when an
obstacle is moved into the parking space.
Active Parking Assist does not relieve you of
the responsibility of paying attention. If you
rely solely on Active Parking Assist, you could cause an accident and injure yourself and oth-
ers.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring.
G
WARNING
Objectsl ocated above the height range of
Active Parking Assist will 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 therefore guide you into the
parking space too early. This may lead to a
collision. For this reason, you should avoid
using Active Parking Assist in such situations. Driving systems

Blind Spot Assist Important safety notes
G
WARNING
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some vehi-
cles and is no substitute for attentive driving.
Blind Spot Assist cannot detect road and traf-
fic conditions. It may fail to detect narrow
vehicles, such as motorcycles or bicycles, or
only detect them too late.
Monitoring may be affected by dirty sensors,
strongs pray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all. Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
General notes
Blind Spot Assist uses aradar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from speeds of
30 km/h. Awarning displayint he exterior
mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical
and audible collision warning. For monitoring,
Active Blind Spot Assist uses sensors in the
rear bumper.
For Blind Spot Assist to assist you when driv-
ing, the radar sensor system must be activa-
ted (Y page 225) and operational.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 368). Driving systems

G
WARNING
Blind Spot Assist monitors certain area sinthe
immediate vicinity of yourv ehicle. Vehicles
that approach and drive past 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 complet ewidth of the
neighbourin glane. For this reason, vehicles in
the nextl ane may no tbedetected, especially
if they are driving in astaggered formation in
differen tlanes .This may be the case if vehi-
cles are driving at the edge of their lane that
is furthest away from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others. Blind Spot Assist monitors the area up to
3.0 mbehind your vehicle and directly nextto
your vehicle, as shown in th ediagram.
If th elanes are narrow ,vehicles drivin ginthe
lan ebeyond th elan en exttoy our vehicl emay
be indicated, especially if th evehicles are not
drivin ginthemiddle of their lane. This may
be th ecaseift here are vehicles at th eedge
of their lan enearest your vehicle. Due to th
enature of th esystem:
R warnings may be issued in error when driv-
ingc lose to crash barrier sorsimilar solid
lane borders.
R warnings may be interrupted when driving
alongside long vehicles, for example lor-
ries, for aprolonged time.
The two radar sensors for Blin dSpot Assist
are integrated int othe sides of the rear
bumper .Make sure that th ebumpe risfree of
dirt, ice or slush in the vicinity of the sensors.
The sensors must not be covered, for exam-
ple by cycle racks or overhanging loads. Fol-
lowing asevere impact or in the event of dam-
age to the bumpers, have the function of the
sensors checked at aqualified specialist
workshop. Blind Spot Assist may otherwise
not work properly.

Lane Keeping Assist Important safety notes
G
WARNING
Lane Keeping Assist does not keep your vehi-
cle in its lane. It is only an aid and may detect
the lane markings on the road incorrectly or
not at all. The system may be impaired or may not func-
tion if:
R
there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray.
R there is glare, e.g. from oncomingt raffic,
the sun, or reflection from other vehicles.
R the windscreen is dirty, misted up or cov-
ered, for instancebyas ticker, in the vicinity
of the camera
R several or no lane markings for asingle lane
are present.
R the lane markings are worn away,d ark or
covered up, e.g. by dirt or snow.
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected.
R the lane markings on the road are unclear,
e.g. near roadworks.
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge.
R the road is narrow and winding.
Lane Keeping Assist cannot detect road and
traffic conditions. It is not asubstitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt your driving
style to suit the prevailing road and weather
conditions. Always pay attention to traffic
conditionsa nd your surroundings. Otherwise,

General notes
Active Blind Spot Assist uses aradar sensor
system to monitor the area to the sides of
your vehicle which are behind the driver. A
warning display in the exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lane, you
will also receive an optical and audible warn- ing. If
arisk of lateral collision is detected,
corrective braking may help you avoid acol-
lision. To support the course-correcting brake
application, Active Blind Spot Assist uses the
forward-facin gradar sensor system. The free
space in the direction of travel is then evalu-
ated.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
The radar sensor system is switched off auto-
matically in the vicinit yofradio telescope
facilities (Y page 368).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be activated (Y page 225) and operational.
Monitoring range G
WARNING
Active Blind Spot Assist monitors certain
areas in the immediate vicinit yofyour vehicle.
Vehicles that approach and drive past at high
speeds are not detected. No visual nor audi-
ble warnings are emitted and the system does
not brake the vehicle to correc tyour course.
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.
This may be the case if vehicles are driving at
the edge of their lane that is furthest away
from your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others. Driving systems
