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 ofacollision, per-
sons or objects.
Under the following circumstances, the rear
view camera will not function, or will function in
al imited 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 aheated garage in winter, causing arapid
change in temperature.
Rif the camera lens is dirty or obstructed.
Observe the notes on cleaning (Ypage 257).
Rif the rear of the vehicle is damaged. In this
case, have the camera position and setting
checked at aqualified specialist workshop.
Do not use the rear view camera in these situa-
tions. You could otherwise injure others or dam-
age object sand 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-mounted bicycle
rack).
Guide lines are alwayss hown 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 correctw heel size category
(
Ypage 267). 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 atailgate, the rear view camera
is protected from raindrops and dust by means
of aflap. 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.
Switching the rear view camera on or
off
XTo switch on: make sure that the key is in
position 2in the ignition lock.
XShift the transmission to position R.
On vehicles with atailgate, the rear view cam-
era flap opens. The audio display shows the
area behind the vehicle. The rear area shown
is divided by guide lines.
In vehicles with atrailer coupling installed, the
function mode of the rear view camera can be
switched over when the trailer is reached. The
rear view camera then changes the viewing
angle and shows alocating aid for the ball cou-
pling of the trailer tow hitch to help reach the
drawbar.
XTo switch function mode: select and con-
firm "Reverse parking" function :or "Cou-
pling up atrailer“ function ;using the audio
system control knob.
Information on the audio system control knob
can be found in the separate operating
instructions.
The symbol of the selected function is high-
lighted.
XTo switch off: shift the transmission to posi-
tion Nor D.
The dynamic guide lines are hidden and after
about 15 sthe rear view camera switches
itself off.

The accurac yofthe speedometer and odometer
displays is legally prescribed. Determining the
speed is dependen tonthe wheel size or the
rolling circumference of the wheels. If you
change the wheel size on your vehicle, make
sure it is assigned to the correct wheel size cat-
egory (
Ypage 267). If you change wheel size
category without recoding the contro lunit, the
speedometer indication will be inaccurate. Driv-

If you change the wheel size on your vehicle,
make sure it is assigned to the correct wheel
size category (
Ypage 267). If you change wheel
size category without recoding the control unit,
the speedometer indication will be inaccurate.
The current vehicle speed may then be higher
than the speed displayed in the speedometer.
The speed can also be shown in the displayi n
the form of adigital speedometer:

!
Do not drive in the overrevving range, as this
could damage the engine.
HEnvironmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consumption
of your vehicle and harms the environment as
ar esult of increased emissions.
The red band in the tachometer indicates the
engine's overrevving range.
To protect the engine, the fuel supply is inter-
rupted when the red band is reached.
Outside temperatured isplay
You should pay special attention to road condi-
tions when temperatures are around freezing

On vehicles without steering wheel buttons, you
can have the coolant temperature shown in the
