Driving

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
The Lane positioning assist system is
automatically activated, after selecting Highway
Driver Assist mode.
For more information on the Highway Driver
Assist system, refer to the corresponding
section.
The selection is confirmed by the display of
the symbols on the instrument panel or on the
head-up display (if fitted), 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 button again (confirmed when the symbol
disappears).
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.
–


V
ehicle not subject to strong lateral g-forces.
–

Direction indicators not activated.
Regulation
The driver must hold the steering wheel
properly.
When regulation 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.
This position is not necessarily the centre of the
lane.
The driver can feel movements in the steering
wheel.
At any time, the driver can change the position of
the vehicle by intervening on the steering wheel
and maintaining the position until the system has
taken it into account. If the chosen position is too
off-centre, an automatic re-centering manoeuvre
can occur. The system adjusts to the newly
defined position.
Pausing/Suspending the
system
The driver must act promptly if they believe that the traffic conditions or the
state of the road surface require their
intervention, by moving the steering wheel to
temporarily suspend system operation. Any
action on the brake pedal that causes the
Adaptive cruise control
system to be paused
will also cause the system to be paused.
If the system detects that the driver is not
holding the wheel firmly enough, it
triggers a series of gradual alerts and then
deactivates itself if there is no response from
the driver.
If the function is suspended due to the
prolonged release of the force holding
the steering wheel, the system must be
reactivated by pressing the button again.

6When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
Supplementing the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of the
vehicle is below 6 mph (10 km/h).
Front parking sensor operation is suspended if
the vehicle stops for more than three seconds in
forward gear, if an obstacle is no longer detected
or the vehicle speed exceeds 6
mph (10 km/h).
The sound emitted by the speaker (front or rear) locates the obstacle relative to
the vehicle, in front or behind it.
Side parking sensors

Using four additional sensors located on the
sides of the bumpers, the system records the
position of obstacles during the manoeuvre and
indicates them when they are located alongside
the vehicle.
Only fixed obstacles are indicated
correctly. Moving obstacles detected at
the beginning of the manoeuvre may be
indicated mistakenly, while moving obstacles
that appear alongside the vehicle but were
not previously recorded will not be indicated.
Objects memorised during the
manoeuvre will no longer be stored after
switching off the ignition.
Deactivation/Activation
The settings are changed via the Driving/Vehicle touch screen menu.
The system status is memorised when the
ignition is switched off.

The display is immediately updated with the type
of view selected.
The system status is not saved when the ignition
is switched off.
Operating principle

Using one or two cameras, the close
surroundings of the vehicle are recorded whilst
manoeuvring at low speed.
An image from above your vehicle in its close
surroundings is reconstructed (represented
between the brackets) in real time and as the
manoeuvre progresses.
It facilitates the alignment of your vehicle when
parking and allows obstacles close to the vehicle
to be seen. It is automatically deleted if the
vehicle remains stationary for too long.
With 360 vision, the image is created using
both cameras, when going forward and when
reversing.
When the function is activated, it is possible
that the view from above is not displayed. If the system is activated when the vehicle has
already moved, the view from above can be fully
displayed.
