Cruise control - Specific
recommendations
The cruise control function does not guarantee compliance with the maximum
authorised speed and the safety distance
between vehicles, the driver remains
responsible for their driving.
In the interest of public safety, only use cruise
control if the traffic conditions enable vehicles
to drive at a steady speed and maintain an
adequate safety distance.
Remain vigilant while cruise control is
activated. If you press and hold one of the
speed setting modification buttons, your
vehicle may change speed very abruptly.
When descending a steep hill , the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the vehicle speed.
On steep climbs or when towing, the set
speed may not be reached or maintained.
Exceeding the programmed speed
setting
You can temporarily exceed the speed
setting by pressing the accelerator pedal (the
programmed speed flashes).
To return to the speed setting, release the
accelerator pedal (when the set speed is
reached again, the displayed speed stops
flashing).

the Adaptive Cruise Control with Stop&Go in
conjunction with the Lane Positioning Assist.
These two functions must be activated and in
operation.
This system is especially suitable for driving on
motorways and main roads.
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.

The system's status is saved when the ignition is
switched off.
Adaptive cruise control
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids and
to

Cruise control - particular
recommendations.
This system automatically maintains the vehicle
speed at a value set by the driver (speed
setting), while respecting a safety distance from
the vehicle in front (target vehicle) previously set
by the driver. The system automatically manages
the acceleration and deceleration of the vehicle.
With the Stop
& Go function, the system
manages braking until the vehicle comes to a
complete stop and the restarting of the vehicle.
The brake lamps come on if the vehicle is slowed down by the system.
The system is not operational in the event of
a brake lamp failure.


To do this, the system uses a camera fitted at the
top of the windscreen and a radar fitted in the
front bumper.
Primarily designed for driving on main
roads and motorways, this system only
works with moving vehicles driving in the
same direction as your vehicle.
If the driver activates the direction
indicator to overtake a slower vehicle,
cruise control may temporarily reduce the
distance to the target vehicle to facilitate
overtaking, without exceeding the speed
setting.

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

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.

11 7
Driving
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.

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).

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

ehicle speed between 43 and 112 mph (70
and 180 km/h).
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.




â–º 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
