Active Parking Assist
General notes
Active Parking Assist is an electronic parking
aid. The system uses ultrasound sensors to
measure the road on both sides of the vehicle
and indicates suitable parking spaces. It can
then actively steer and brake the vehicle to help
you to park and exit the parking space.
Active Parking Assist includes the PARKTRONIC
parking aid which indicates visually and audibly the distance between your vehicle and an
object. To do this, PARKTRONIC uses the ultra- sonic sensors of the Active Parking Assist
(
Ypage 151).
Important safety notes
Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. You are responsible for safe
maneuvering, parking and pulling away. Make
sure that no persons, animals or objects are in
the maneuvering range.
When you deactivate PARKTRONIC, Active Park-
ing Assist will also be deactivated.

The message displays depend on the language
setting of the audio system. The following rear
view camera displays are examples.
Important safety notes
!Objects that are not at ground level appear
further away than they actually are, for exam-
ple:
Rthe bumper of the vehicle parked behind
Rthe drawbar of a trailer
Rthe ball coupling of a trailer tow hitch
Rthe tail-end of a truck
Rslanted posts
Only use the camera guide lines for orienta-
tion. Do not get any closer to objects than the
lowest horizontal guide line. You may other-
wise damage your vehicle and/or the object.
The rear view camera is only an aid. It cannot
replace your own awareness of the immediate
surroundings. You are responsible for safe
maneuvering and parking. Make sure that there
are no persons, animals or objects in the maneu- vering area while maneuvering and parking in
parking spaces.
The rear view camera may show obstacles in
perspectival distortion, incorrectly or not at all.
The rear view camera cannot display all objects
located very near and/or under the rear
bumper. It does not warn you of a collision, per-
sons or objects.
Under the following circumstances, the rear
view camera will not function, or will function in
a limited manner:
Rif the tailgate or rear door is open.
Rif it is raining very heavily or snowing, or it is
foggy.
Rat night or in very dark places.
Rif the camera is exposed to very bright light.
White lines may appear in the camera image.
Rif the area is lit by fluorescent light or LED
lighting. The camera image may flicker.
Rif the camera lens fogs up, e.g. when driving
into a heated garage in winter, causing a rapid
change in temperature.
Rif the camera lens is dirty or obstructed.
Observe the notes on cleaning (Ypage 267).
Rif the rear of the vehicle is damaged. In this
case, have the camera position and setting
checked at a qualified specialist workshop. Do not use the rear view camera in these situa-
tions. You could otherwise injure others or dam-
age objects and the vehicle while parking and
maneuvering.
The field of vision and other functions of the rear view camera may be restricted due to additional
accessories on the rear of the vehicle (e.g.
license plate holder, rear-mount

ed bicycle
rack).
Guide lines are always shown at road level. In
trailer mode, the guide lines are shown at the
level of the trailer coupling.
If you change wheel size, make sure they corre- spond to the correct wheel size category
(
Ypage 277). If the category is changed without
recoding the control units in the vehicle, the rear
view camera cannot be precisely calibrated. The
guide lines at road level or at the level of the
trailer tow hitch will not be displayed correctly.
In vehicles with a tailgate, the rear view camera
is protected from raindrops and dust by means
of a flap. When the rear view camera is activa-
ted, this flap opens.
The flap closes again when:
Ryou have finished the maneuvering process
Ryou switch off the engine
For technical reasons, the flap may remain open
briefly after the rear view camera has been
deactivated.
