Driving

If any of the following malfunctions occurs,

do not use the system:

► Following an impact on the windscreen

close to the camera or on the front

bumper.

The system identifies the edges of the traffic

lane and steers the vehicle to keep it inside this

lane and maintain the lateral position chosen by

the driver.

To do this, the system uses a camera placed on

the upper part of the windscreen.

► When following a narrow vehicle.

► If a brake lamp is not working.

Reactivate the system when conditions allow.

Situations in which the driver is prompted

to immediately resume control: – Excessively

sharp deceleration by the vehicle in front of you.

If the vehicle has undergone any of the

following modifications, do not use the

system:– Carrying long objects on roof bars.

This system is particularly suited to driving on

motorways and main roads.

► Towing.

► Front end of the vehicle modified (for

example by adding long-range headlamps

or painting the front bumper).

Activation/Deactivation

The Lane positioning assist system is

automatically activated, after selecting Drive

Assist Plus mode.

► Obstructed radar and/or camera.

► When a vehicle cuts in sharply between your

vehicle and the one in front.

For more information on the Drive Assist Plus

system, 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:

Malfunction

Some vehicles on the road may be poorly

perceived or interpreted by the camera

and/or the radar (e.g. truck), which can lead

to an incorrect evaluation of distances and

result in inappropriate acceleration or braking

of the vehicle.

In the event of a malfunction, dashes are

displayed (orange) instead of the speed setting.

This warning lamp comes on,

accompanied by a message and

an audible signal, to confirm the

malfunction.
