Active Parking Assist will only detect parking
spaces:
Rthat are parallel to the direction of travel
Rthat are at least 59 in (1.5 m) wide
Rthat are at least 51 in (1.3 m) longer than
your vehicle
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol as a
status indicator in the instrument cluster.
When a parking space has been detected, an
arrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the
driver's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing thev
button on the multifunction steering wheel.
A parking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it.

Parking tips:
RThe way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the curb. If necessary, you should
cancel the parking procedure with Active
Parking Assist.
RYou can also select preselect transmission
positionD. The vehicle redirects and does
not drive as far into the parking space.
Should the gear change occur too soon to
achieve a sensible parking position, the
parking procedure will be aborted.
Exiting a parking space
In order that Active Parking Assist can
support you when you exit the parking space:
Ryou need to have parked using Active
Parking Assist.
Rthe border of the parking space must be
high enough at the front and the rear. A
curb stone is too small, for example.
Rthe border of the parking space must not
be too wide, as the position of the vehicle
must not exceed an angle of 45° to the
starting position as it is maneuvered into
the parking space.
Ra maneuvering distance of at least 3.3 ft
(1.0 m) must be available.

Night View Assist Plus
General notes
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 cameraCpicks up
the infrared light and displays a monochrome
image in COMAND. The image displayed in
COMAND corresponds to a road lit up by high-
beam headlamps. This enables you to see the
road's course and any obstacles in good time.
If pedestrian recognition is activated,
pedestrians recognized by the system are
highlighted in the Night View Assist Plus
display.
Light from the headlamps of oncoming
vehicles does not affect the Night View Assist
Plus display in the multifunction display. This
is also the case if you cannot switch on the
high-beam headlamps due to oncoming
traffic.
iInfrared light is not visible to the human
eye and therefore does not glare. Night
View Assist Plus can therefore remain
switched on even if there is oncoming
traffic.
Important safety notes
Night View Assist Plus is only an aid and is not
a substitute for attentive driving. Do not rely
on the Night View Assist Plus display. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Drive carefully and always adapt
your driving style to suit the prevailing road
and traffic conditions.
The system may be impaired or may not
function if:
Rthere is poor visibility, e.g. due to snow,
rain, fog or spray
Rthe windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera
Ron bends, on uphill gradients or downhill
gradients

reflections
Rpedestrians do not contrast adequately

Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (Ypage 243) and Lane Keeping
Assist (Ypage 245).
Blind Spot Assist
General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph(30 km/h). A warning
display in the exterior mirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lanes,
you will also receive a visual and audible
collision warning. Blind Spot Assist uses
sensors in the rear bumper for monitoring
purposes.
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions
carefully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving.
