General notes
Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention can assist you during
manoeuvring and parking. You may also use
PARKTRONIC ( Y page 182).
Important safety notes
Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or
objects are in the manoeuvring range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park-
ing Assist parking procedure.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tyres.
Active Parking Assist may also display spaces
not suitable for parking, e.g.:
R parking or stopping prohibitions
R in front of driveways or entrances and exits
R unsuitable surfaces

Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
R that are parallel or at right angles to the
direction of travel
R that are parallel to the direction of travel
and are at least 1.5 m wide
R that are parallel to the direction of travel
and at least 1.0 m longer than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 m wider than your
vehicle
i In the case of parking spaces that are at
right angles to the direction of travel,
please ensure that the parking space is
long enough to accommodate your vehicle.
When driving at speeds below 30 km/h, you
will see parking symbol ; as a status indi-
cator in the instrument cluster. When a park-
ing space has been detected, an arrow
towards the right or the left also appears.
Active Parking Assist only displays parking
spaces on the front-passenger side as stand-
ard. 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 Park-
ing Assist by pressing the a button on the
multifunction steering wheel.
The system automatically determines
whether the parking space is parallel or at
right angles to the direction of travel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 15 m away from it.ParkingGWARNING
Active Parking Assist merely aids you by inter-
vening actively in the steering. There is a risk
of accident if you do not apply the brakes
yourself.
Always apply the brakes yourself when park-
ing and manoeuvring.

Parking tips:
R The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion 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 kerb. If necessary, you should can-
cel the parking procedure with Active Park-
ing Assist.
R You can also preselect the forward gear.
The vehicle redirects and does not drive as
far into the parking space. Should a gear be
changed too early, the parking procedure
will be cancelled. A sensible parking posi-
tion can no longer be achieved from this
position.
Exiting a parking space
In order that Active Parking Assist can sup-
port you when you exit the parking space:
R the border of the parking space must be
high enough. A kerb stone is too small, for
example.
R the 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 manoeuvred into
the parking space.
R a manoeuvring distance of at least 1.0 m
must be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.

Once you have exited the parking space com-
pletely, the steering wheel is moved to the
straight-ahead position. You hear a tone and
the message Park Assist switched off
appears in the multifunction display. You will
then have to steer and merge into traffic on
your own. PARKTRONIC is still available. You
can take over the steering before the vehicle
has exited the parking space completely. This
is useful, for example when you recognise
that it is already possible to pull out of the
parking space.
Cancelling Active Parking Assist
You can cancel Active Parking Assist at any
time.

must steer again yourself.
Towing a trailer
For vehicles with a trailer tow hitch, the min-
imum required length for parking spaces is
slightly increased.
If you have attached a trailer to your vehicle,
you should not use Active Parking Assist.
Once the electrical connection is established
between your vehicle and the trailer, Active
Parking Assist is no longer available. PARK-
TRONIC is deactivated for the rear area.
Reversing camera
General notes
Reversing camera : is in the boot lid handle.
The reversing camera is an optical parking
and manoeuvring aid. It uses guide lines to
show the area behind your vehicle in the
Audio/COMAND display.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
The reversing camera is protected from rain-
drops and dust by means of a flap. When the
reversing camera is activated, this flap opens.
Only once the manoeuvring process has been
completed and the reversing camera has
switched off does the flap close again. For
technical reasons, the flap may remain open
briefly after the reversing camera has been
deactivated. If you switch off the engine, the
flap will also close.
i The text of messages shown in the
COMAND display depends on the language
setting. The following are examples of
reversing camera messages in the
COMAND display.
Observe the notes on cleaning
( Y page 291).
Important safety notes
The reversing camera is only an aid. It is not
a substitute for your attention to the imme-
diate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals
or objects in range while manoeuvring and
parking.
Under the following circumstances, the
reversing camera will not function, or will
function in a limited manner:
R if the tailgate is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In
this case, have the camera position and
setting checked at a qualified specialist
workshop.

Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist ( Y page 197) and Lane Keeping
Assist ( Y page 199).
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 speeds of
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 lane, you will also receive an optical
and audible collision warning. For this pur-
pose, Blind Spot Assist uses sensors in the
rear bumper.
