Lane departure warning (Side As-
sist) The lane departure warning uses radar sen-
sors t
o monit
or the areas behind the vehicle
››› page 9. The system does this by measur-
ing the vehicle's distance from other vehicles
and its speed differential. The lane departure
warning will not work at speeds of less than
approx. 15 km/h (9 mph).
The lane width is not detected individually,
but is rather pre-configured in the system.
Thus if you are driving in wide lanes or in be-
tween two lanes, the indications may be in-
correct. Furthermore, the system can detect
vehicles driving in the lane next to you (if
there are any), and can also detect station-
ary objects such as dividers, and thus give an
incorrect indication.
Light indication
The control lamp provides an indication on
the corresponding side regarding the traffic
situation behind the vehicle, if it is deemed to
be critical. The control lamp of the left-hand
side ››› Fig. 188
indicates the traffic situation
to the rear left of the vehicle, and the control
lamp of the right-hand side ››› Fig. 189
, indi-
cates the traffic situation to the rear right of
the vehicle. Keep the warning lamps zone of the lane de-
part

the likes that may interfere with your visibility.
