Q A – Warning indicator in exterior mirror does not
light up
R
The direction indicator has not been actuated. The
S Rear Turn Assist is therefore not active after driving
off and the motorbike located in the blind spot is not
T
detected. A fast approaching vehicle may also not be
detected. Warning indicator in exterior mirror does
U
not light up.
V
B – Warning indicator lights up in the information
stage
W
If the relevant direction indicator is switched on in
X
driving situation A, the warning indicator in the ex-
terior mirror lights up. Turn assist alerts you to the
Y
fact that you may have overlooked a vehicle.
Z
C – Warning indicator flashes in the warning stage
136
If, in driving situation B, the driver has initiated
turning off by steering to the relevant side and this
results in his own calculated driving path crossing
that of a detected vehicle, the warning indicator in
the exterior mirror flashes briefly several times and
then lights up. This warns you of a potential collision
with a vehicle that may have been overlooked.
Driving around bends
When driving around a bend, Lane Change Assist
may react to a vehicle driving in the next lane but
one and the warning indicator in the exterior mirror
may light up.
Lane Change Assist cannot detect vehicles in tight
bends.
e Take additional care when driving around bends
and where there are lanes with differing widths.
Lane width
The Lane Change Assist detection area covers the
two adjacent lanes (left and right) on lanes of
standard width regardless of whether you are driving
exactly in the middle or at the edge of the lane.
When driving on narrow lanes, this area may cover
even more lanes, particularly when driving at the
edge of a lane. In such situations, vehicles driving
two lanes away may be detected and Lane Change
Assist may switch to the information or warning
stage.
Likewise, when driving on very wide lanes, vehicles
in the adjacent lane may not be detected as they are
outside the detection area.
