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. Aparking symbol indicates
as uitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting aparking
space. You may also use PARKTRONIC
(
Ypage 174).
Important safety notes
Active Parking Assist is merely an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. Make sure that no persons, ani-
mals or object sare in the maneuvering range.
When PARKTRONIC is switched off, Active Park-
ing Assist is also unavailable.
GWARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
result inacollision with another road user.
There is arisk 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 obsta-
cles such as curbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may also display spaces
not suitable for parking, e.g.:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
ROn narrow roads, drive as close to the parking
space as possible.
RParking spaces that are littered or overgrown
might be identified or measured incorrectly.
RParking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.
RSnowfall or heavy rain may lead to aparking
space being measured inaccurately.

travel and at least 39.5i n(1.0m )wider than

iNotet hat Activ eParking Assist cannot
measure the size of aparking space if it is at
right angles to the direction of travel. You will
need to judge whether your vehicle will fit into the parking space.
When drivingats peeds below 19 mph
(3 0k m/ h),y ou will see the parking symbol as a
status indicator in the instrumentc luster. When
ap arking space has been detected, an arrow
towards the right or the left also appears. By
default,A ctiveP arking Assist only displays park-
ing spaces on the front-passenge rside. 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 acknowl-
edge the use of Activ eParking Assist by press-
ing the abutton on the multifunction steer-
ing wheel. The system automatically determines
whether the parking space is parallel or at right
angles to the direction of travel.
Ap arking space is displayed while you are driv-
ing past it, and until you are approximately 50 ft (1 5m)a way fromi t.

GWARNING
If you leave the vehicle when it is only being
braked by Activ eParking Assist it could roll

Rthere is amalfunction in the system or in
the voltage supply.
Rthe electrical system in the engin ecom-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected.
Rthe accelerator pedal has been depressed,
e.g. by avehicle occupant.
There is arisk of an accident.

Active Parking Assist no longer supports you
with steerin ginterventions and brake applica-
tions. When Active Parking Assist is finished,
you must steer and brake again yourself.
PARKTRONIC is still available.
Parking tips:
RThe way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous 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 aparking space, or not
far enough into it. In some cases, it may also
lead you across or ontot he curb. If necessary,
you should cancel the parking procedure with
Active Parking Assist.
RYou can also select preselect transmission
position D.The vehicle redirectsa nd does not
drive as far into the parking space. Should the
transmission change take place too early, the
parking procedure will be canceled. Asensi-
ble parking position can no longer be ach-
ieved from this position.
Exiting aparking space
In order that Active Parking Assist can support
you when you exit the parking space:
Rthe border of the parking space must be high
enough at the front and the rear. Acurb 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 maneuvering into the parking
space.
Ram aneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Active Parking Assist can only assist you with
exitin gaparking space if you have parked the vehicle parallel to the direction of travel using
Active Parking Assist.
iIf PARKTRONIC detect
sobstacles, Active
Parking Assist brakes automatically whilst the
vehicle exits the parking space. You are
responsible for braking in good time.
XStart the engine.
XRelease the electric parking brake.
XSwitch on the turn signal in the direction you

360° camera
General notes
The 360° camera is asystem consisting of four
cameras.
The system processes images from the follow-
ing cameras:
RRear view camera
RFront camera
RTwo side cameras in the exterior mirrors The cameras capture the immediate surround-
ings of the vehicle. The system supports you, for
example when parking or if vision is restricted at
an exit.
You can show images from the 360° camera in
full-screen mode or in six different split-screen
views on the multimedia system.
Asplit-screen
view also includes atop view of the vehicle. This
view is calculated from the data supplied by the
installed cameras (virtual camera).
The six split-screen views are:
Rtop view and picture from the rear view cam-
era (130° viewing angle)
Rtop view and image from the front camera
(130° viewing angle without displaying the
maximum steering wheel angle)
Rtop view and enlarged rear view
Rtop view and enlarged front view
Rtop view and images from the rear-facing side
cameras (rear wheel view)
Rtop view and images from the forward-facing
side cameras (front wheel view)
When the function is active and you shift the
transmission from Dor Rto N,t he guide lines
are hidden in the multimedia system.
When you change between transmission posi-
tions Dand R,you see the previouslys elected
front or rear view.
Distances measured by PARKTRONIC will also
be optically displayed:
Rin split screen view as red or yellow brackets around the vehicle icon in the top view, or
Rat the bottom right as red or yellow brackets
around the vehicle symbol in full-screen mode
The line thickness and color of the brackets
show how far the vehicle is from an object.
Ryellow brackets with thin lines: PARKTRONIC
