Recommendation

In addition to Speed Limit Recognition and
Recommendation, the driver can select the
speed displayed as a speed setting for the speed
limiter or cruise control using the speed limiter or
cruise control 'store' button.
For more information on the Speed
limiter, Cruise control or Adaptive
cruise control, refer to the corresponding
sections.

2. Memorise the speed setting
Qualifier plate
detected Display of the
speed associated with the qualifier plate
Speed limit at certain times Example:


19 mph (30 km/h)
(for example)
with a "clock" symbol
The units for the speed limit (mph or km/h) depend on the country you are
driving in.
This should be taken into account so that you
observe the speed limit.
For the system to work correctly when
changing country, the speed unit in the
instrument panel must correspond to that of
the country you are driving in.
The automatic reading of road signs is a driving aid system and does not always
display speed limits correctly.
The speed limit signs present on the road
always take priority over the display by the
system.
The system is designed to detect signs that
conform to the Vienna Convention on road
signs.
Specific speed limits, such as those for
heavy goods vehicles, are not displayed.
The display of the speed limit in the
instrument panel is updated when passing
a speed limit sign intended for cars (light
vehicles).
Activation / Deactivation
By default, the system is automatically activated
at every engine start.
It is set via the Driving / Vehicle touch
screen menu.

or a qualified workshop.
Cruise control - particular
recommendations
For the safety of everyone, only use the
cruise control where the driving
conditions allow running at a constant speed
and keeping an adequate safety distance.
Remain vigilant when the cruise control
is activated. If you hold one of the speed
setting modification buttons down, a very
rapid change in the speed of your vehicle may
occur.
When descending a steep hill , the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the speed of your
vehicle.
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).
Operating limits
Never use the system in the following
situations:
–

In an urban area with the risk of
pedestrians crossing the road.
–


In heavy traffic (except versions with the
Stop & Go function).
–


On winding or steep roads.
–


On slippery or flooded roads.
–


In poor weather conditions.
–

Memorising speeds
This function, used only for the speed limiter
and programmable cruise control, lets you
save speed settings that will subsequently be
proposed for the purpose of configuring these
two systems.
You can memorise multiple speed settings for
each of the two systems.
By default, some speed settings are already
memorised.
As a safety measure, the driver must only change speed settings when stationary.
Changing a speed setting
Speed settings can be activated,
deactivated, selected and changed in the
Driving
/ Vehicle touch screen menu.

Switching on cruise control and setting
the speed
With a manual gearbox, your speed must be
between 19 and 112 mph (30 and 180 km/h).
With an automatic EAT6 gearbox, your speed
must be between 1 and 112 mph (2 and
180 km/h).
With an automatic EAT8 gearbox, your speed
must be between 0 and 112 mph (0 and
180 km/h).
► Press button 2 or 3: the current speed
becomes the speed setting (minimum 19 mph
(30 km/h)) and cruise control is immediately
activated (green display).
Highway Driver Assist
Only available on versions with automatic
gearbox.
This system automatically adjusts the speed and
corrects the trajectory of the vehicle, using the
Adaptive Cruise Control with Stop&Go function
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 limits of the laws of physics and the
capabilities of the vehicle. Certain road
infrastructure elements or vehicles present on
the road 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.
Adaptive Cruise Control
Refer to the General recommendations on the
use of driving and manoeuvring aids and to
Cruise control - particular recommendations.
This system automatically maintains the speed
of your vehicle at a value which you set (speed
setting), while keeping a safe distance from the
vehicle in front (target vehicle), and which has
been set beforehand by the driver. The system
automatically manages the acceleration and
deceleration of the vehicle.
With the Stop function , the system manages
the braking until the vehicle comes to a complete
stop.
With the Stop
& Go function, the system
manages the 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.
It can be dangerous to drive if the brake
lamps are not in perfect working order.


To do so, it has a camera located at the top of
the windscreen and, depending on version, a
radar located 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 operates a direction indicator
to overtake a slower vehicle, the cruise
control allows the vehicle to temporarily
approach the vehicle in front to assist the
overtaking manoeuvre, without ever
exceeding the speed setting.
Some vehicles present on the road may
not be properly seen or may be poorly
interpreted by the camera and/or radar (e.g. a
lorry), which may lead to a poor assessment
of the distances and lead to the vehicle
inappropriately accelerating or braking.
