Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to aparking
space being measured inaccurately. R
pay attention to the PARKTRONIC
(Y page 186) warning messages during the

always correct. This has adirec tinfluence
on the parking characteristics of the vehi-
cle.
R the wa yyourv ehicl eisp ositioned in the

cle. Look through the windscreen when
manoeuvring. Make sure that there are no
people or animals in the area in which you are
manoeuvring. In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Night View Assist Plus camera :picks up
the infrared light and display samonochrome
image in COMAND .The image displayed in
COMAND corresponds to aroad lit up by
main-beam headlamps. This enables you to
see the road's course and any obstacles in
good time. When pedestrian recognition is
active, pedestrians recognised by the system
are highlighted in the Night View Assist Plus
display.
Light from the headlamps of oncomingv ehi-
cles does not affect the Night View Assist Plus
displayint he multifunction display. This is
also the case if you cannot switch on the main-beam headlamps due to oncomingt

fic.
i Infrared light is not visible to the human
eye and therefore does not dazzle. Night

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
