The button

Fig. 141 is backlit if the
system has been disconnected or has a fault.
The Lane Assist system can actively intervene
as of approximately 60 km/h (35 mph) if it
has detected lane lines.
If the control lamp of the instrument panel
display is off, it means that the assist system
is connected but not ready to adjust steering
(system in passive state) or disconnected.
When you activate a turn signal, the system
temporarily goes into a passive state in order
to allow manual lane change.
Driver intervention prompt
If the steering is not corrected manually, the
system prompts the driver through an indica-
tion on the instrument panel display and
acoustic warnings to actively take the steer-
ing wheel.
If no reaction is obtained from the driver, the
system switches to a passive state.
Through an indication on the instrument pan-
el display and acoustic warnings, the driver is
also prompted to drive through the centre of
the lane if the steering correction lasts more
than reasonable.
Steering wheel vibration
If the system stops displaying the lane lines
while assisting with steering, it can cause the
steering wheel to vibrate. This situation re-
quires the driver to actively assume control.
Switching off the Lane Assist system in the
following situations
Due to the limits of the Lane Assist system,
switch it off in the following situations:
●
When more attention is required of the driv-
er
●
When driving in a sporty style
●
In unfavourable weather conditions
●
On roads in poor condition
●
In areas of road works
WARNING
The intelligent technology in the Lane As-
sist system cannot change the limits im-
posed by the laws of physics and by the
v
ery nature of the system. Careless or un-
controlled use of the Lane Assist system
may cause accidents and injury. The sys-
tem is not a replacement for driver aware-
ness.
●
Always adapt your speed and the dis-
t
ance to the vehicles ahead in line with visi-
bility, weather conditions, the condition of
the road and the traffic situation.
●
Always keep your hands on the steering
wheel so it can be turned at any time.
●
The Lane Assist system does not detect
all road markings. The road surfaces, road
structures or objects in poor condition can
be incorrectly detected as road markings
under certain circumstances by the Lane
Assist system. In such situations, switch the
Lane Assist system off immediately.
●
Please observe the indications on the in-
strument panel and act as is necessary.
●
In the following situations there may be
counter-productive interventions of the
system or it may be that the system does
not intervene at all. In these situations, spe-
cial attention is required from the driver
and, where appropriate, the temporary de-
activation of the lane assist warning sys-
tem:
–
In very sporty driving situations.
–
In adverse weather conditions and
roads in poor condition.
–
When passing through areas undergo-
ing works.
–
Before gradient changes of grade and
river beds.
●
Always pay attention to the vehicle's sur-
roundings.
