warning.
It lights up
It turns on once briey: the lane departure
warning is activated and ready to operate, i.e.
when activating the system.
It lights up continuously: the lane departure
warning has detected a vehicle in the blind
spot.
Flashes
A vehicle has been detected in the adjacent
lane and the turn signal has been engaged in
the direction of the detected vehicle ››› .
For vehicles that are also equipped with Lane
Assist ››› page 173, a warning to switch lanes
will also appear even though the turn signal
has not been engaged (Lane Assist “Plus”
››› page 184).
The control lamps light up when the ignition is
switched on and should turn o after approxi-
mately 2 seconds. This is the time taken for the
function check.
If there are no indications from the control
lamp of the lane departure warning, this means
that the lane departure warning has not detec-
ted any other vehicles at the rear area ›››
.
When the exterior lighting is low, the intensity
with which the control lamps come on is dim-
med. The user can modify the intensity of the
control lamps with up to 5 levels in the infotain-
ment system menu.
WARNING
Ignoring any lit warning lamps and the corre-
sponding messages could lead to accidents
and serious injuries.
•
Never ignore the warning lamps or mes-
sages.
•
Carry out the necessary operations.
NOTICE
Failure to heed the control lamps and corre-
sponding text messages when they light up
may result in damage to the vehicle.
Lane departure warning (Side As-
sist)
The lane departure warning uses radar sen-
sors to monitor the areas behind the vehicle
››› page 13. The system does this by measur-
ing the vehicle's distance from other vehicles
and its speed dierential. 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-congured in the system. Thus
if you are driving in wide lanes or in between
two lanes, the indications may be incorrect.
Furthermore, the system can detect vehicles
driving in the lane next to you (if there are any),
and can also detect stationary objects such as
dividers, and thus give an incorrect indication.
Indication on the exterior mirror
The control lamp provides an indication on the
corresponding side regarding the traic situa-
tion behind the vehicle, if it is deemed to be
critical. The ››› Fig. 140 control lamp on the
left-hand side indicates the traic situation to
the rear left of the vehicle, and the ››› Fig. 141
control lamp on the right-hand side indicates
the traic situation to the rear right of the vehi-
cle .
In the case of retrotted tinted windows or
windows with tinted lm, the indications of the
external mirrors may not be seen clearly.
