Drive Assist Plus
This system automatically adjusts the speed and corrects the trajectory of the vehicle, using
Adaptive cruise control with Stop&Go function in
conjunction with Lane positioning assist.
These two functions must be activated and in
operation.
For more information on Adaptive cruise
control and Lane positioning assist , refer to
the corresponding sections.
The system assists the driver by acting on the steering, acceleration and braking
within the physical limits and capacities of the
vehicle. Certain road infrastructure elements
or vehicles in the surroundings may not be
properly seen or may be poorly interpreted by
the camera and radar, resulting in an
unexpected change in direction, a lack of
steering correction and/or inappropriate
management of acceleration or braking.

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.
This 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
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 ASSIST button
again.
Automatic suspension
Suspension of the system is accompanied by a
specific audible signal.

Driving
6The 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.
Selecting the system
Two options:
– Either when the vehicle is already driving on
an eligible road, the driver selects the system by
activating the Drive
Assist 2.0 system.
–

Or when the driver is already using Drive
Assist Plus, 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.
–


by acting on the pedals.
For more information on the Direction
indicators

, refer to the corresponding section.
Operating conditions
– Eligible roads: roads with separate
carriageways with prohibited access for
pedestrians and cyclists.

Driving
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.
Interrupting the lane change
It is possible that while changing lane, the
necessary conditions for the operation of the
system
may no longer be met.


If this occurs before one of the wheels has
crossed the line separating the two lanes, the
system automatically returns the vehicle to
its original lane (confirmed by the display of
a manoeuvre cancellation message on the
instrument panel and an audible signal). The
system is then automatically deactivated.


If this occurs when the lane change has
started, the system prompts the driver to
immediately retake control of the vehicle (confirmed by the display of a message on the
instrument panel and an audible signal), and the
system is automatically deactivated.
Refused lane change
request
When operating the direction indicator or
pressing
2-OK, if the necessary conditions
are not met, the lines appear in orange on the
instrument panel.


The system keeps the vehicle in the original
lane. The system is deactivated and the semi-
automatic lane change is not carried out.
