Introduction
WARNING
The Lane Assist System helps the driver
stay in his/her lane within the physical lim-
its of the system. This function is not suita-
ble and is not designed to keep the vehicle
automatically in the lane.
●
The intelligent technology in the Lane As-
sist system cannot change the limits im-
posed by the laws of physics and by the very
nature of the system. Careless or uncon-
trolled use of the Lane Assist system may
cause accidents and injury. The system is
not a replacement for driver awareness or
manoeuvres when driving.
If the speed of travel considerably ex-
ceeds the speed limit detected by the traf-
fic signal detection system, a relevant warn-
ing is displayed in the instrument panel dis-
play.
Using the camera located in the windscreen,
the Lane Assist system detects the limits
(lane lines) dividing the lanes in which the
vehicle is travelling. If the vehicle gets too
close to the detected lane limits, the system
alerts the driver through a corrective motion
of the steering wheel. The driver can cancel
the steering corrective action at any time.
●
In the event of joining a highway without
speed limitation, the recommended speed
is automatically saved as the desired speed.
If a higher speed has previously been saved
for a motorway without a speed limit, this is
used instead of the recommended speed.
●
Always adapt your speed and the distance
to the vehicles ahead in line with visibility,
weather conditions, the condition of the
road and the traffic situation.

Always keep your hands on the steering
