General information on assist systems
be fitted at the rear, front and side, depending on
the vehicle’s equipment. The range depends on
the location in which the ultrasonic sensors are
fitted. The side zone is detected and analysed as
the vehicle is moving past. When you switch the
vehicle off and on again or open the door, or after
the vehicle has been stationary for a while, the
ambient surroundings may have changed. In this
case, the side zone is not shown.
Sensors for detecting

surroundings
Areas covered by sensors and cameras
Cameras
Only use the camera image on the display to as-
sist you if the picture is clear and discernible.
Please also note that the view on the display is
enlarged and distorted. Under certain circum-
stances, objects may appear different on the dis-
play, or may be depicted inaccurately.
Fig. 78 Areas covered by the sensors
The reversing camera is only able to detect the
area shown in red 1 ðFig. 79. Only this area is
shown on the centre display ð
.
Further information
– Applies to: vehicles with surround view cam-
eras: System limitations may occur if the exteri-
or mirrors are not folded out completely. Make
sure that the exterior mirrors are fully folded
out while you are driving.
Fig. 79 Area covered by reversing camera
The assist systems evaluate the data from differ-
ent sensors and cameras installed in the vehicle.
Do not use the assist systems if the area around
the sensors and cameras or the underbody has
been damaged. This can impair the function of
the sensors and cameras or cause malfunctions.
Have the systems checked by a qualified work-
shop.
– Applies to: vehicles with electric folding exteri-
or mirrors: System limitations may occur when
manually adjusting the exterior mirrors. The ex-
terior mirrors must only be folded in/out elec-
trically.
– The sensors and cameras and their surrounding
area must never be covered or painted as this
can impair the function of the systems that de-
pend on them. Please ensure that the sensors
and cameras are clean and kept free of snow,
ice and any other deposits. Accessories, stick-
ers, decals, paint etc. must not be applied to
the sensors and must be kept completely out-
side the sensors’ and cameras’ range of vision.
– When replacing a factory-fitted front number
plate holder, the new holder must be of the
same size and material as the original one. On
vehicles without a factory-fitted front number
plate holder, a holder must not be fitted in the
front area, as this can impair the function of
the vehicle’s systems.
Radar sensors
Depending on the vehicle’s equipment, the entire
area surrounding the vehicle can be detected
ðFig. 78.
The radar sensors at the rear corners of the vehi-
cle are designed for normal lane widths and mon-
itor the lanes immediately to the left and right of
your vehicle.
Ultrasonic sensors
The ultrasonic sensors detect the area surround-
ing the vehicle at close range. The sensors may
