6This position is not necessarily the centre of the
lane.
You can feel the steering wheel moving.
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
intervention on the brake pedal that causes
the Adaptive cruise control to pause will also
cause the system to pause.
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 ASSIST button
again.
Automatic pause
Pausing the system is accompanied by a specific
audible signal. –

T
riggering of the ESC.
–
Insufficient lane detection. In this case, the
Active lane departure warning system function
can take over
, and the system will reactivate
itself once the operating conditions are met
again.
Suspension by the driver
– Travelling outside the lane limits.
– T oo tight a grip on the steering wheel or
dynamic action on the steering wheel.

Speed adjustment during
cornering
(with Highway Driver Assist 2.0)
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids and the
Cruise control - particular
recommendations.
In addition to Adaptive Cruise Control with
Stop&Go and Lane positioning assist systems,
this system regulates the speed of the vehicle in
bends.
It adapts the speed, with or without target
vehicle, in certain bends on motorways or main
roads.
The speed is only adjusted if the vehicle speed is
not compatible with the angle of the bend.
The reduction in speed on a bend is adapted
to the situation in order to ensure the bend is
navigated comfortably.
In the presence of a target vehicle, it also
maintains the inter-vehicle distance.
This system does not manage bends that are too tight ("hairpin bend" for example).

–

V
ehicle speed between 43 and 112 mph (70
and 180 km/h).
Operation
The vehicle is moving at the
speed setting and is monitoring
bends.
The system gradually decreases
the speed in the bend to
negotiate it comfortably.
Temporary driver intervention
If the driver believes that the speed is too slow or
too fast, they can act on the pedals.
Pressing the brake pedal deactivates Highway
Driver Assist 2.0, while pressing the accelerator
pedal temporarily suspends it.
Semi-automatic lane
changing
(with Highway Driver Assist 2.0)
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
This system assists the driver in changing lanes.
To do this, it uses the camera located at the top
of the windscreen, the radar located at the front
and the four angle radars fitted in the bumpers.
The steering wheel is equipped with a hands-on detection system to avoid
distraction on the part of the driver.
For more information on the Hands-on
detection, refer to the corresponding section.
The system cannot in any circumstances replace the need for vigilance on the part
of the driver. The driver remains responsible
for their driving by monitoring their
surroundings and keeping their hands on the
steering wheel.
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 intervention on the brake pedal or the
accelerator pedal that causes the adaptive
cruise control to be paused or suspended will
also cause the system to deactivate.
System selection
Two possibilities:
– Either , when the vehicle is already driving on
an eligible road, the driver selects the system via
the Highway Driver Assist 2.0 system activation.
–

Or
, when the driver is already using Highway
Driver Assist, the vehicle suggests selecting
the system upon arriving at an eligible road by
pressing the OK button.
Activation/Deactivation

► Activate the direction indicator on the side
corresponding to the lane change, whether or
not passing the resistance point of the lighting
control stalk.
The driver can regain control of the vehicle at
any time:
–

by deactivating the direction indicator if the
vehicle has not yet crossed the line.
–


by firmly holding the steering wheel.

Authorised lane change request
When operating the direction indicator, if the
necessary conditions are met, the message
"OK?" is displayed on the instrument panel,
accompanied by an audible signal.




► After checking the surroundings, press
2-OK to confirm the start of the lane change
manoeuvre.
The message "Stay alert"
is displayed as a
reminder that the driver is responsible for the
manoeuvre.


The system then proceeds with the vehicle’s
lane change.
Once the manoeuvre has been carried out, the
system is automatically deactivated and the lane
positioning assist takes over.
If the direction indicator has been set beyond the
point of resistance, the driver must pull it back.
The driver must hold the steering wheel correctly.
As soon as the semi-automatic lane change
begins, the system directs the vehicle to the
target lane by small actions on the steering to
position it in the destination lane.
You can feel the steering wheel moving.
Interruption of lane change
It is possible that during a lane change, the
necessary conditions for the functioning of the
system may no longer be met.


If this occurs before either wheel has crossed
the line between the two lanes, the system will
automatically return the vehicle to its original
lane (confirmed by displaying a manoeuvre
cancellation message on the digital instrument
panel and an audible signal). Then the system
automatically deactivates itself.


If this occurs while the lane change has begun,
the system asks the driver to immediately
regain control of the vehicle (confirmed by the
display of a message on the digital instrument

Active lane departure warning system
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The system corrects the vehicle's trajectory by
alerting the driver as soon as it detects a risk of
involuntary
lane departure or crossing of a verge
or hard shoulder (depending on version).
To do this, the system uses a camera, placed on
the upper part of the windscreen, identifying the
lane markings on the ground and the side of the
road (depending on version).
This system is particularly useful on motorways
and main roads.


Conditions for operation
– Vehicle speed between 43 and 112 mph (70
and 180 km/h).
–

Road marked with a central dividing line.
–


Steering wheel held in both hands.
– Direction indicators off upon activation of the
system.
–

ESC system activated and operational.
The system helps the driver only if there is a risk of the vehicle unintentionally
wandering from the lane it is being driven in. It
does not manage the safe driving distance,
vehicle speed or braking.
The driver must hold the steering wheel with
both hands so that they can maintain control
when the conditions no longer allow the
system to intervene (e.g. in the event that
the central dividing line marking on the road
surface disappears).
Operation
As soon as the system identifies a risk of
involuntarily crossing one of the lane markings
detected on the ground or a lane boundary
(e.g.
grass verge), it performs the trajectory
correction necessary to restore the vehicle to its
original lane.
The driver will notice a turning movement of the
steering wheel.
This warning lamp flashes during trajectory correction.
The driver can prevent the correction by firmly holding the steering wheel
(e.g.
during an emergency manoeuvre).
The correction is interrupted immediately if
the direction indicators are operated. While the direction indicators are activated and
for a few seconds after switching them off, the
system considers that a change of trajectory is
intentional and no correction is triggered during
this period.
