Lane positioning assist

For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids.
The system identifies the limits of the traffic
lane and steers the vehicle inside this lane to
maintain it in the lateral position chosen by the
driver.
To do this, the system uses a camera placed on
the upper part of the windscreen.
This function is primarily suitable for driving on
motorways and main roads.
Activation/Deactivation
Lane positioning assist is automatically activated,
after selecting Highway Driver Assist mode.
For more information on Highway Driver Assist,
refer to the corresponding section.
The selection is confirmed by the display of the
symbols on the instrument panel, representing
the steering wheel and the side lines.
The colour of the symbols depends on the
operating state of the system:
(grey)
One or more operating conditions is not met; the
system is paused.
(green)
All operating conditions are met; the
system is active.
(orange)
System malfunction.
If the driver no longer wishes to use the system
for some time, they can deactivate it by pressing
the ASSIST button again (confirmed by the
disappearance of the Driving aids mini-view on
the instrument panel).
The system status is saved when the
ignition is switched off.
Operating conditions
– Adaptive cruise control active.
– ESC system operational.
– ASR system activated.
– No trailer detected.
– No 'space-saver' spare wheel in use.
– Vehicle not subject to strong lateral g-forces.
– Direction indicators off upon activation of the
system.
Cruise control
The driver must hold the steering wheel properly.
When cruise control is activated, the symbols are
displayed in green: with small steering inputs,
the system steers the vehicle and keeps it in the
position chosen by the driver in the traffic lane.
