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).

Highway Driver Assist
Only available on versions with the EAT8
automatic gearbox and drive selector.
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.
Primarily designed for driving on main
roads and motorways, this system only
works with moving vehicles driving in the
same direction as your vehicle.

Adaptive cruise control
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids and the
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 function , the system manages
braking until the vehicle comes to a complete
stop.
With the Stop
& Go function , the system
manages braking until the vehicle comes to a
complete stop and restarts the vehicle.
The brake lamps come on if the vehicle is slowed down by the system.
It can be dangerous to drive if the brake
lamps are not in perfect working order.


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.
