maneuvering aid. It shows the area behind your vehicle with guide lines in the COMAND
display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
iThe text of messages shown in the
COMAND display depends on the language
setting. The following are examples of rear
view camera messages in the COMAND
display.
Important safety notes
The rear view camera is only an aid. It is not a
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.

Rif the tailgate is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent light or LED
lighting (the display may flicker)
Rif there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
Rif the camera lens is dirty or obstructed
Rif 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

engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached.
Outside temperature display
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the temperature measured
and does not record the road temperature.
The outside temperature display is in the mul-
tifunction display (

A change in the outside temperature is shown
in the multifunction display after a delay.
Coolant temperature display
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
!A display message is shown if the coolant
temperature is too high.
If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The
engine will otherwise be damaged. The coolant temperature gauge is in the
instrument cluster on the right-hand side
(
Ypage 41).
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 248 ‡ (120 †).
