a
new speed setting.
If there is a
difference of less than 6 mph
(9
km/h) between the speed setting and
the speed displayed by the Speed Limit
recognition and recommendation, the
" MEM " symbol is not displayed.
Depending on the road conditions, several
speeds may be displayed.

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, a very rapid
change in the speed of your vehicle may
o c c u r.
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
The speed setting can be exceeded
temporarily
by pressing the accelerator
pedal (the programmed speed flashes).
To return to the speed setting, release
the accelerator pedal (when this speed is
reached again, the display of the speed
stops flashing).
Operating limits
Never use the system in the following
situations:
-

i
n an urban area with the risk of
pedestrians crossing the road,
-

i
n heavy traffic (except versions with
the Stop & Go function),
-

o
n winding or steep roads,
-

o
n slippery or flooded roads,
-

i
n unfavourable climatic conditions,
-

d
riving on a speed circuit,
-

d
riving on a rolling road,
-

u
se of snow chains, non-slip covers or
studded tyres.
Programmable cruise
control
Refer to the General recommendations
on the use of driving and manoeuvring
aids and to Cruise control – par ticular
recommendations .
This system automatically keeps
the vehicle's speed at the cruise
value programmed by the driver
(speed setting), without using the
accelerator pedal.
The cruise control is switched on manually.
It requires a
minimum vehicle speed of 25 mph
(40


km/h).
With a
manual gearbox, it requires the
engagement of third gear or higher.
With an automatic gearbox, it requires the
engagement of mode D or of second gear or
higher in mode M .
The cruise control remains active after
changing gear regardless of the gearbox
type on engines fitted with Stop & Start.

Malfunction
As a precaution, it is recommended
t hat the cruise speed chosen be close
to the current speed of your vehicle, so
as to avoid any sudden acceleration or
deceleration of the vehicle.
Memorising speeds
Linked to the speed limiter and programmable
cruise control, this function allows speed limits
to be registered which will then be suggested
as settings for these two systems.
You can memorise several speed settings for
each for system.
By default, some speed settings are already
memorised. As a
safety measure, the driver must
only modify the speed settings when
stationary.
Memorising speeds
From the Driving/Vehicle menu of
the touch screen, select " Driving
functions ", then "Memorised
speed settings ".
"MEM " button
Flashing dashes indicate a fault with the cruise
c ontrol system.
Have it checked by a

For more information on the Speed limiter or
Cruise control , refer to the associated section.
With this button, you can select a
memorised
speed setting to use with the speed limiter or
the programmable cruise control.
Highway Driver Assist
This system provides active assistance in
keeping the vehicle in position in its lane.
It associates the Adaptive Cruise Control with
Stop & Go function and Active Lane Keeping
Assist.
These two functions must be activated and in
operation.
These functions are especially suitable for
driving on motor ways and main roads.
For more information on Adaptive Cruise
Control and Active Lane Keeping Assist ,
refer to the corresponding sections. The system assists the driver in managing
the steering, acceleration and braking
within the limits of the laws of physics
and the capabilities of the vehicle. Some
road infrastructure elements or vehicles
present on the road may not be properly
seen or may be poorly interpreted by the
camera and radar, which may lead to an
unexpected change in direction, a lack of
steering correction and/or inappropriate
management of the acceleration or
braking.
Adaptive Cruise Control
Refer to the General recommendations
on the use of driving and manoeuvring
aids
and to Cruise control – par ticular
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 stops completely.
With the Stop & Go function, the system
manages the braking until the vehicle stops
completely, and also manages its restarting.
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 motor ways, 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 your vehicle to temporarily
approach the vehicle in front to assist
the overtaking manoeuvre, without ever
exceeding the speed setting.

Driving

148
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.
