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.

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.
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.
–

Action on the brake pedal (resulting in a pause
until cruise control is reactivated) or accelerator
pedal (suspension for as long as the pedal is
depressed).
–


Pausing of
Adaptive cruise control.
–

Deactivation of the
ASR.

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).

120
Driving
Operating conditions
– Eligible roads: roads with separate
carriageways with prohibited access for
pedestrians and cyclists.
–

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

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.
