This system displays the maximum authorised
speed in the instrument panel, according to
the speed limits in the country in which you are
driving, using:
-

S
peed limit signs detected by the camera.
-

Sensors
Units of speed
Ensure that the units of speed displayed
on the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with
what is authorised locally.
In case of doubt, contact a

CITROËN
dealer or a

qualified workshop.
The operation of the sensors as well as
the associated functions may be disturbed
by sound inter ference such as those
emitted by noisy vehicles and machinery
(e.g. lorries, pneumatic drills), by the
accumulation of snow or dead leaves
on the road or in the event of damaged
bumpers and mirrors.
A front or rear impact to the vehicle can
upset the sensors' settings, which is not
always detected by the system: distance
measurements may be distorted.
The sensors do not detect obstacles that
are too low (pavements, studs) or too thin
(trees, posts, wire fences).
Certain obstacles located in the sensors'
blind spots may not be detected or may no
longer be detected during the manoeuvre.
Certain materials (fabrics) absorb sound
waves: pedestrians may not be detected.

This system warns the driver of the presence
of another vehicle in the blind spots of their
vehicle (areas hidden from the driver's field
of vision), as soon as this presents a potential
danger.
A fixed warning lamp appears in the door mirror
on the side in question:
-
i

mmediately, when being overtaken,
-

a
fter a delay of about one second, when
overtaking a
vehicle slowly.
In addition to the fixed warning lamp in the door
mirror on the side in question, a correction of
trajectory will be felt if you attempt to cross
a
lane marking with the direction indicator
activated, to help you avoid a
collision.This driving aid system is designed to
improve safety when driving and is in no
circumstances a
substitute for the use
of the interior rear view mirror and door
mirrors. It is the driver's responsibility to
constantly check the traffic, to assess the
relative distances and speeds of other
vehicles and to anticipate their movements
before deciding whether to change lane.
Activation/Deactivation
The function is activated and
deactivated in the Driving/Vehicle
menu of the touch screen.
The state of the system stays in the memory
when switching off the ignition.
The system is automatically deactivated
when towing with a
towing device
approved by CITROËN.
Operation
The alert is given by an orange warning lamp
coming on in the relevant door mirror, as soon
as a
vehicle – car, lorry, bicycle – is detected.
A correction of trajectory will be felt if you
attempt to cross a
lane marking with the
direction indicator flashing.
The following conditions must be met for this:
-

a
ll vehicles are moving in the same direction
and in adjacent lanes,
-

t
he speed of the vehicle must be between
7
and 87 mph (12 and 140 km/h) for the
alert and between 40
and 87 mph (65 and
140
km/h) for a correction of trajectory,
-

t
he system must be activated to trigger
a
change of trajectory,
-

Malfunction
The system may suffer temporary
interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet sur face
or moving from a
dry area to a wet area
can cause false alerts (for example,
the presence of a
fog of water droplets
in the blind spot angle is interpreted as
a


vehicle).
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or
snow.
Take care not to cover the warning zone in
the door mirrors or the detection zones on
the front and rear bumpers with adhesive
labels or other objects; they may hamper
the correct operation of the system.
The system is automatically deactivated
when towing with a
towing device
approved by CITROËN.
If a

fault occurs, this warning lamp comes on
in the instrument panel, accompanied by the

Parking sensors
Refer to the General recommendations on
the use of driving and manoeuvring aids.
Rear parking sensors
The system is switched on by engaging reverse
g e a r.
This is confirmed by an audible signal.
The system is switched off when you come out
of reverse gear.
Audible assistance
The function signals the presence of obstacles
present within the vehicle sensors' detection
zone.
The proximity information is given by an
intermittent audible signal, the frequency of which
increases as the vehicle approaches the obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or left)
allows you to identify the side on which the
obstacle is located.
Adjusting the audible signal
Visual assistance
Using sensors located in the bumper, this
function warns of the proximity of obstacles
(e.g. pedestrian, vehicle, tree, barrier) entering
their field of detection.
On versions equipped with
CITROËN Connect Radio, pressing
this button opens the audible signal
volume adjustment window.It supplements the audible signal by displaying
bars on the screen that move progressively
nearer to the vehicle (white: more distant
obstacles; orange: close obstacles; red: very
close obstacles).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
In addition to the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of
the vehicle is still below 6
mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in for ward gear, if an obstacle is no longer
detected or when the speed of the vehicle
exceeds 6
mph (10 km/h).

Driving

168
The sound emitted by the speaker (front or
rear) locates the obstacle in relation to the
vehicle, in front or behind.
Deactivation/Activation
The function is deactivated and
activated in the Driving/Vehicle
menu of the touch screen.
The state of the system stays in the memory
when the ignition is switched off.
The rear parking sensors system will
be deactivated automatically if a
trailer
or bicycle carrier is connected to
a

towing device installed in line with the
manufacturer's recommendations.
In this case, the outline of a
trailer is
displayed at the rear of the image of the
vehicle. The parking sensors are deactivated while the
Park Assist system is measuring a
space.
For more information on the Park Assist , refer
to the corresponding section.
Operating limits
The tilting of the vehicle if the boot is very
loaded can affect the distance measurements.
Malfunction
If a malfunction occurs, when
s hifting to reverse, one of these
warning lamps comes on in the
instrument panel, accompanied by
the display of a
message and an
audible signal (short beep).
If the malfunction occurs while the
parking sensors are being used, it
causes the function to deactivate.

Principle of operationThe screen is divided into two parts: on the
left, a contextual view; on the right, a view from
above the vehicle in its close surroundings.
The parking sensors supplement the
information on the view from above the vehicle.
AUTO mode is activated by default.
In this mode, the system chooses the best view
to display (standard or zoom) according to the
information from the parking sensors.
You can change the type of view at any time
during a


manoeuvre. Using one or two cameras, the close
surroundings of the vehicle are recorded whilst
manoeuvring at low speed.
An image from above your vehicle in its close
surroundings is reconstructed (represented
between the blue brackets) in real time and as
the manoeuvre progresses.
This representation facilitates the alignment of
your vehicle when parking and allows obstacles
close to the vehicle to be seen. With Top 360
Vision, the image is created using
both cameras, when going for ward and when
reversing.
When the function is activated, it is possible
that the view from above is not displayed. If
the system is activated when the vehicle has
already moved, the view from above can be
fully displayed.Top Rear Vision
