Speed limit recognition
This system allows the speed limit detected by
the camera to be displayed in the instrument
panel.
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 as you pass a speed limit sign
i
ntended for cars (light vehicles).
The units for the speed limits (mph or
km/h)
depend on the country you are
d
riving in.
It
should be taken into account so that
y
ou observe the speed limit.
For the system to operate correctly
when
you change country, the units for
s
peed in the instrument panel must be
those
for the country you are driving in. The
automatic reading of road signs is a
d
riving assistance system and does not
a
lways display speed limits correctly.
The
speed limit signs present on the
r
oad always take priority over the
d
isplay by the system.
The system cannot in any
circumstances replace the need for
vigilance
on the part of the driver.
The
driver must observe the driving
r
egulations and must adapt the speed
o
f the vehicle to suit the weather and
traffic.
It is possible for the system to not
display the speed limit if it does not
detect
a speed limit sign within a preset
p
eriod.
The
system is designed to detect signs
t
hat conform to the Vienna Convention
on
road signs.
To maintain correct operation of the
system:
regularly clean the area in front
o
f the camera.Principles
Using a camera at the top of the windscreen, this system detects and reads speed limit and
end
of speed limit signs.
The
system also takes account of information
o
n speed limits from the navigation system
ma
pping.

Memorising the speed setting
This memorisation is in addition to the display
of Speed limit recognition .
The driver can choose to adapt the speed
setting
to the speed limit suggested, by
p
ressing the memorisation button at the speed
l
imiter controls, with the standard cruise
control, the dynamic cruise control or the
dynamic
cruise control with Stop function.
This
speed setting then replaces the previous

Operating limits
The legislation on speed limits is specific to each country.
The
system does not take account of reduced
s
peed limits in the following cases:

oor weather (rain, snow),
-
a
tmospheric pollution,
-
t
railer, caravan,
-

-
w
indscreen area ahead of the camera dirty,

Limits of operation
The system cannot exceed the limits of the laws of physics.
It is recommended that the system be
deactivated when the "space-saver" spare
wheel
is in use.
The system should not be activated when
towing
a trailer.
In certain critical situations, the system will
encourage
the driver to immediately take back
c
ontrol:
-
i
f the vehicle in front slows down too much
or too suddenly, and the driver does not
brake,
-
i
f a vehicle comes between your vehicle
and
the vehicle in front. As
the radar's field of detection is quite narrow,
i
t is possible that the system may not detect:
-
v
ehicles of reduced width (motorcycles,
scooters...),
-
v
ehicles not running in the middle of the
lan
e,
-
v
ehicles entering a corner,
-
v
ehicles suddenly pulling out.The
cruise control does not take account of:
-
p
edestrians, cyclists, animals,
-
s
tationary vehicles (traffic jam, red light,
b
reakdown...),
-
v
ehicles crossing a junction,
-
v
ehicles driving in the opposite direction.

Deactivation of the system is recommended in
the following situations:
-
d
riving on a road sur face in poor condition,
-
u
nfavorable weather conditions,
-
d
riving on slippery sur faces (black ice).
The
system is not designed for the following

ituations:
-
d
riving on a speed circuit,
-
d
riving with a trailer,
-
d
riving on a rolling road,
-
d
riving on unstable sur faces.
In the event of a fault with the system, you are
alerted
by the illumination of these warning
lam

the
display of a message and an audible signal.
Have
the system checked by a CITROËN
d
ealer or a qualified workshop.

Fatigue detection system
Depending on version, the "Driving time warning system" may be combined with the
"
Fatigue detection system".
Using
a camera placed at the top of the
w
indscreen, the system assesses the driver's
l
evel of vigilance by identifying variations in
t
rajectory compared to the lane markings.
This system is particularly suited to fast roads
(speed
higher than 40 mph (65 km/h)).Once the system considers that the behaviour
of
the vehicle suggests a certain level of fatigue
o
r inattention by the driver, it triggers the first
l
evel of alert.
The
driver is then alerted by the message
"Ta
k e c a r e !", accompanied by an audible
signal.
After
three first level alerts, the system triggers
a
new alert with the message "Take a break! ",
accompanied by a more pronounced audible
signal. In
certain driving conditions (poor road
s
ur face or strong winds), the system
m
ay give alerts independent of the
d
river's level of vigilance.
The following situations may inter fere
w
ith operation of the system or prevent
it working:
-
p
oor visibility (inadequate lighting
o
f the roadway, falling snow, heavy
r
ain, dense fog, ...),
- d azzle (headlamps of an oncoming v
ehicle, low sun, reflections on
a
damp road, leaving a tunnel,
a
lternating shade and light, ...),
-
w
indscreen area located in front
of
the camera: dirty, misted, frost-
covered,
snow-covered, damaged
o
r covered by a sticker,
-
l
ane markings absent, worn,
m
asked (snow, mud) or multiple
(
roadworks,
...
),
-
c
lose to the vehicle ahead (lane
markings
not detected),
-

360 Vision
This system provides a view in the instrument
panel of the near surroundings of your vehicle,
u
sing cameras mounted at the front and rear of
y
our vehicle and under the door mirrors.
Depending
on the angle of view chosen (front
v
iew, rear view or 360° panoramic view),
3
60 Vision provides special visual assistance
i
n particular driving conditions such as when
e
ntering a blind junction or manoeuvring in
a
reas of reduced visibility.
Once activated, this function operates up to
9 mph
(15 km/h). Above 18 mph (30 km/h), the
f
unction is deactivated automatically. This system is a visual aid which in no
circumstances can replace the need for
vigilance
on the part of the driver.
The images provided by the cameras
m
ay be deformed by the relief. The
p
resence of areas in shade, in sunny
conditions, or of low ambient light may
d
arken the image and reduce contrast.Forward vision
The camera located in the front bumper is
activated and views of the areas located at
front
left and front right appear simultaneously
i
n the instrument panel.
Rear vision
The camera located in the tailgate is activated and the view of the area behind your vehicle is
displayed in the instrument panel and behaves
like
a reversing camera, whatever the position
o
f the gear selector lever.
The blue lines represent the width of your
vehicle
(excluding mirrors): they move
a
ccording to the position of the steering wheel.
The
red line represents a distance of 30 cm
f
rom the rear bumper, and the two green
l
ines, 1 m and 2 m from the rear bumper,
respectively.
Rear vision is displayed automatically
when
engaging reverse, regardless of
t
he state of the system.
