Problems with the seat heating
ProblemPossible causes/consequences andMSolutions
The seat heating has
switched off prema-
turely or cannot be
switched on.The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off electrical consumers that you do not need, such as
the rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat heating will
switch back on automatically.

ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.

some time. You can adjust the selected
mirror using adjustment button =as long
as the indicator lamp is lit.
X Press adjustment button =up, down, or to
the left or right until you have adjusted the
exterior mirror to the correct position. You
should have a good overview of traffic con- ditions.
The convex exterior mirrors provide a larger
field of vision.
After the engine has been started, the exte-
rior mirrors are automatically heated at low
outside temperatures. Heating takes a maxi-
mum of ten minutes.
iYou can also heat up the exterior mirrors
manually by switching on the rear window
defroster.

Rear view camera
General notes
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.
iThe text shown in the Audio/COMAND
display depends on the language setting.
The following are examples of rear view
camera messages in the Audio/COMAND
display.
Observe the notes on cleaning ( Ypage 279).
Important safety notes

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 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
winter
R if the camera lens is dirty or obstructed.
Observe the notes on cleaning(Y page 279)
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).
