Driver assistance
Warning mode
– The warning signal may not light up in time
or may not light up at all if other vehicles
are approaching very quickly, or if you are
overtaking other vehicles quickly.
As soon as you activate a turn signal, the system
warns you of objects which it judges to be critical
by flashing the warning signal on the correspond-
ing exterior mirror.
Note
Depending on the vehicle equipment, if other
driver assist systems detect that you are in dan-
ger of leaving your lane, the warning signal may
flash to warn you of objects which the system
judges to be critical, even if you have not activa-
ted a turn signal. The system may initiate a cor-
rective steering input as an additional warning
ðpage 206, Lane departure warning.
– The warning signals on the exterior mirrors
may not be properly visible if tinted foil is
affixed to the side windows on the driver's
or passenger's side.
– The systems are not available in towing
mode. If the towing bracket is not factory-
fitted the systems may not be switched off
automatically. The functions must not be
used when towing a trailer.
Instrument cluster display
Applies to: driver assist display with surroundings shown
– The area covered by the sensors ðFig. 145
is an example and does not represent the
range of the sensors to scale.
In addition to the warning signal on the exterior
mirror, a graphic for the side assist (information
and warning level) is shown in the instrument
cluster 2 . The graphic ðFig. 146 is only shown if
the tab has been selected in the instrument
cluster.
Adjusting the side assist settings
Applies to: vehicles with side assist
You can switch the side assist on/off or adjust the
individual settings in the Driver assist menu
ðpage 175. The settings depend on the equip-
ment fitted in your vehicle.
System limits
The system uses the data from the radar sensors
at the rear corners of the vehicle ðpage 174,
Fig. 119. The sensors are designed for normal
lane widths and monitor the lanes immediately
to the left and right of your vehicle. In certain sit-
uations it is possible that the system may react
to vehicles in your own lane or two lanes away, or
to objects at the edge of the lane. The warning
signal then lights up even though there are no
vehicles in the critical area. Such situations may
include:
Available settings:
Brightness – Always adjust the brightness with
the side assist function switched on so that you
can monitor the selected setting in the warning
signals on the exterior mirrors. Please adjust the
brightness of the warning signal for the informa-
tion mode so that it does not distract you while
you are looking at the road in front. Because the
display brightness is automatically adjusted in
accordance with the ambient light level, it is pos-
sible that the display may already have been au-
tomatically adjusted to the lowest or highest set-
ting.
– When driving at the edge of your own lane
– When driving in narrow lanes
– When driving through a corner
– If there are high barriers next to the lane
– When driving through roadworks
Note
WARNING
– The warning signals light up briefly each
time the ignition is switched on to indicate
that the system is activated.
– Please note the safety precautions and sys-
tem limitations of the supporting systems,
sensors and cameras ðpage 171 to
ðpage 174.
