X Switch the ignition back on. The problem may be caused by an external source of radio or
ultrasound waves.
X See if PARKTRONIC functions in a different location. Active Parking Assist
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
maneuvering and parking. You may also use
PARKTRONIC (Y page 178).
Important safety notes Active Parking Assist is merely an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. Make sure that
no persons, animals or objects are in the
maneuvering range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
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 curbs slowly and not at a sharp angle. Otherwise, you may damage
the wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example:
R where parking or stopping is prohibited
R in front of driveways or entrances and exits
R on unsuitable surfaces Driving systems
181Driving and parking Z

Parking tips:
R On narrow roads, drive as close to the park-
ing space as possible.
R Parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
R Parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 180) warning messages during the
parking procedure.
R You can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be canceled.
R When transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R Never use Active Parking Assist when snow
chains are installed.
R Make sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
Use Active Parking Assist for parking spaces:
R that are parallel or at right-angles 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
Detecting parking spaces Objects located 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. G
WARNING
If there are objects above the detection range, Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
For further information on the detection
range (Y page 179).
Active Parking Assist does not support you
with parking spaces at right-angles to the
direction of travel if:
R two parking spaces are located directly
next to one another
R the parking space is directly next to a low
obstacle such as a low curb
R you park forwards
Active Parking Assist does not support you
with parking spaces that are parallel or at
right-angles to the direction of travel if:
R the parking space is on a curb
R the parking space is apparently blocked,
for example by foliage or grass paving
blocks
R the range of movement is too small
R the parking space is bordered by an obsta-
cle which is not clearly defined such as a
tree or a trailer 0043
Detected parking space on the left
0044 Parking symbol
0087 Detected parking space on the right
Active Parking Assist is automatically activa-
ted when driving forwards. The system is
operational at speeds of up to approximately
22 mph (35 km/h). While in operation, the 182
Driving systemsDriving and parking

system independently 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 at least 59 in (1.5 m) wide
R that are parallel to the direction of travel
and at least 39.5 in (1.0 m) longer than your
vehicle
R that are at right angles to the direction of
travel and at least 39.5 in (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 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 driv-
er'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 the 0076
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 50 ft (15 m) away from it.

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 curb. If necessary, you should can-
cel the parking procedure with Active Park- ing Assist.
R You can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should a gear be changed too early, the parking pro- cedure will be canceled. A sensible parking
position 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 curb is too small, for exam- ple.
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 maneuvering into the park-
ing space.
R a maneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Active Parking Assist can only assist you with exiting a parking space if you have parked thevehicle parallel to the direction of travel using
Active Parking Assist.
X Start the engine.
X Switch on the turn signal in the direction
you are pulling away.
X Shift the transmission to position Dor R.

Rear view camera
General notes Rear view camera
0043is in the trunk lid handle.
The rear view camera is an optical parking and maneuvering 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 rear view camera is protected from rain-
drops and dust by means of a flap. When the
rear view camera is activated, this flap opens. Only once the maneuvering process has been
completed and the rear view camera has
switched off does the flap close again. For
technical reasons, the flap may remain open
briefly after the rear view 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 rear view camera messages in the COMAND
display.
Observe the notes on cleaning (Y page 291).
Important safety notes The rear view camera is only an aid. It is not a
replacement for your attention to your imme-
diate surroundings. You are always responsi- ble for safe maneuvering and parking. When
maneuvering or parking, make sure that there are no persons, animals or objects in the area
in which you are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner:
R if the trunk lid 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
event, have the camera position and setting checked at a qualified specialist workshop
The field of vision and other functions of the
rear view camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. license plate holder, bicycle rack).
Activating/deactivating the rear view camera X
To activate: make sure that the SmartKey
is in position 2in the ignition lock.
