Lane departure warning system
System which detects the involuntary crossing
of longitudinal traffic lane markings on the
ground (solid or broken line).
Sensors, fitted below the front bumper, trigger
a warning if the vehicle drifts over a lane
marking (speed higher than 50 mph (80 km/h)).
This system is particularly useful on motor ways
and main roads.
Activation
F When switching the ignition on or with the engine running, press this button; the
indicator lamp comes on.
The lane departure warning system
cannot in any circumstances replace
the need for vigilance on the part of the
driver.
It is necessary to observe driving
regulations and take a break every
two

hours.
deactivation
You are warned by the vibration of the driver's
seat cushion:
-
o
n the right-hand side, if the marking on
the ground has been crossed on the right,
-

o
n the left-hand side, if the marking on the
ground has been crossed on the left.
No warning is transmitted while the direction
indicator is active and for approximately
20
seconds after the direction indicator is
switched off.
A warning may be transmitted if a direction
marking (e.g. arrow) or non-standard marking
(e.g. graffiti) is crossed.
detection Operating fault
The detection may be impeded:
- i
f the sensors are dirty (mud, snow...),
-

i
f the markings on the ground are
worn,
-

i
f there is little contrast between
the markings on the ground and
the road sur face.
F

P

ress this button again, the indicator lamp
goes off.
The status of the system remains in the
memory when the ignition is switched off. In the event of a malfunction, the
service warning lamp comes on,
accompanied by an audible signal
and a message in the screen.
Contact a CITROËN dealer or a qualified
workshop.

Blind spot sensors
This driving assistance system warns the driver
of the presence of another vehicle in the blind
spot angle of their vehicle (areas masked from
the driver's field of vision), as soon as this
presents a potential danger.
Operation
This 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 distances and relative speeds of
other vehicles and to predict their movements before deciding whether to change lane.
The blind spot sensor system can never replace the need for vigilance on the part of
the
d
river. F

O
n switching on the ignition, or engine
running, press this button to activate the
function; the warning lamp comes on.
Sensors fitted in the front and rear bumpers
monitor the blind spots.
A 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.

Operating fault
In the event of a fault, the warning lamp in the
button flashes then goes off.
Have it checked by a CITROËN dealer or a
qualified workshop.The system may suffer temporary
interference in certain weather
conditions (rain, hail...).
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.
F

T

o deactivate the system, press this button
again; the warning lamp goes off.
The state of the system remains in memory on
switching off the ignition.
The system is automatically
deactivated when towing with a towbar
approved by CITROËN.

Parking sensors
This system indicates the proximity of an
obstacle (person, vehicle, tree, gate, etc.)
which comes within the field of detection of
sensors located in the bumper.
Certain types of obstacle (stake, roadworks
cone, etc.) detected initially will no longer be
detected at the end of the manoeuvre, if they
are located in blind spots in the sensors' field
of detection.
This system cannot in any circumstances replace
the need for vigilance on the part of the driver.
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.
Rear parking sensors
Audible assistance
The proximity information is given by an
intermittent audible signal, the frequency of which
increases as the vehicle approaches the obstacle.
The sound emitted by the speaker (right or left)
indicates the side on which the obstacle is located.
When the distance between the vehicle and
the obstacle becomes less than approximately
thirty centimetres, the audible signal becomes
continuous.
Visual assistance
This supplements the audible signal by
displaying bars in the screen which move
progressively nearer to the vehicle.
When the obstacle is very close, the "Danger"
symbol is displayed in the screen.

Reversing camera
The reversing camera is activated automatically
when reverse gear is engaged.
The colour image is provided in the touch
screen tablet.The blue lines represent the general direction
of the vehicle.
The blue curved lines represent the maximum
turning circle.
The green lines represent distances of around
1 to 2 metres beyond the edge of the vehicle's
rear bumper.
The red line represents the distance of around
30 cm beyond the edge of your vehicle's rear
b u m p e r.
The lines displayed in the screen do not allow
the position of the vehicle to be determined
relative to tall obstacles (for example: vehicles
nearby).
Some deformation of the image is normal.High pressure jet washing
When cleaning your vehicle, keep the
end of the high pressure lance at least
30 cm from the camera lens.
Clean the camera lens regularly using
a soft cloth.
The reversing camera system may be
accompanied by parking sensors.
This system is a driving aid that does
not replace vigilance on the part of the
driver, who must remain in control of
the vehicle at all times.
