Parking tips:
R The 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 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 cancel the parking procedure with
Active Parking Assist.
R You can also preselect transmission position
D. 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 position can
no longer be achieved from this position.
Exiting a parking space In order that Active Parking Assist can support
you when exiting the parking space:
R the border of the parking space must be high
enough at the front and the rear. A kerb stoneis 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 mmust
be available.
i Vehicles with automatic transmission:
If PARKTRONIC detects obstacles, Active
Parking Assist brakes automatically whilst the vehicle exits the parking space. You are
responsible for braking in good time.
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.
X Start the engine.
X Release the parking brake.
X Switch on the turn signal in the direction you
are pulling away.

Reversing camera
General notes Reversing camera
:is an optical parking and
manoeuvring aid. It shows the area behind your vehicle with guide lines in the multimedia sys-
tem display.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
i The text shown in the multimedia system
display depends on the language setting. The following are examples of reversing camera
messages in the multimedia system display.
Important safety notes The reversing camera 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 there are no persons, animals or
objects in range while manoeuvring and parking.
Under the following circumstances, the revers-
ing camera will not function, or will function in a limited manner:
R if the boot 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 bulbs 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 win-
ter R
if the camera lens is dirty or obstructed.
Observe the notes on cleaning
(Y page 293)
R if the rear of your vehicle is damaged. In this
case, have the camera position and setting
checked at a qualified specialist workshop.
The field of vision and other functions of the
reversing camera may be restricted due to addi-
tional accessories on the rear of the vehicle (e.g.
licence plate holder, bicycle rack).
On vehicles with height-adjustable chassis,
leaving the standard height can result in inac-
curacies in the guide lines, depending on tech-
nical conditions.
i The reversing camera is protected from rain-
drops and dust by means of a flap. When the
reversing camera is activated, this flap opens.
The flap closes again when:
R you have finished the manoeuvring process
R you switch off the engine
R you open the boot
See the notes on cleaning (Y page 293).
For technical reasons, the flap may remain
open briefly after the reversing camera has
been deactivated.

General notes Traffic Sign Assist displays the maximum speed
permitted and overtaking restrictions to the
driver in the instrument cluster. Driving onto a 190
Driving systemsDriving and parking
section of road in the wrong direction triggers a
warning. Traffic Sign Assist detects traffic signs with camera system :attached behind the top
of the windscreen. The data and general traffic
regulations stored in the navigation system are
also used to determine the current speed limit.
If a traffic sign that is relevant to your vehicle is passed, the display of the speed limits and over-
taking restrictions is updated.
The display can also be updated without a visible
traffic sign if:
R the vehicle changes roads (e.g. motorway exit
or slip road)
R a village or town boundary is passed which is
stored in the digital map
R the last traffic sign detected by the camera
has not been repeated
If a sign indicating the end of a restriction (speed
limit or overtaking restriction) is passed, the
sign is displayed for five seconds. The currently applicable traffic regulation continues to be
shown in the assistance graphic display.
The camera also detects traffic signs with a
restriction indicated by an additional sign (e.g. in
wet conditions).
The traffic signs are only displayed with the
restrictions if:
R the regulation must be observed with the
restriction, or
R Traffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the avail- able sources, no speed limit is displayed in the
instrument cluster either. Traffic Sign Assist is not available in all coun-
tries. In this case, symbol :is shown in the
assistance graphic display (Y page 213).Important safety notes Traffic Sign Assist is only an aid and is not always
able to correctly display speed limits and over-
taking restrictions. Traffic signs always have pri-
ority over the Traffic Sign Assist display.
The system may be either functionally impaired
or temporarily unavailable if:
R visibility is poor, e.g. due to snow, rain, fog or
spray
R there is glare, e.g. from the sun being low in
the sky
R there is dirt, ice or misting on the windscreen
in the vicinity of the camera
R traffic signs are hard to detect (dirt, ice, snow)
R the traffic signs are insufficiently lit at night
R signs are ambiguous (e.g. traffic signs on con-
struction sites or in adjacent lanes)
R the information in the digital street map of the
navigation system is incorrect or out of date
Switching the message function on/off If you have activated the Traffic Sign Assist dis-
play in the on-board computer, the traffic regu-
lations (speed limits and overtaking restrictions)
are displayed in the instrument cluster for five
seconds respectively. The wrong-way warning
