top as soon as it is safe to do so. The loss of pressure detected does not
always lead to visible deformation of the
tyre. Do not rely on just a visual check. The alert is maintained until the
reference pressure is reinitialised after
the inflation, repair or replacement of
the tyres concerned. In the event of
the repair or replacement of tyres, the
sensor identifiers must be registered in
the system by a CITROËN dealer or a
qualified workshop.
The spare wheel does not have
a sensor, so there is no need to
reinitialise the the system for running
with the spare wheel fitted.

n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (according to equipment).
Reinitialising the reference
pressure
Before reinitialising the system, ensure
that the pressures in the four tyres are
suitable for the conditions of use of the
vehicle and as specified on the tyre
pressure label.
The under-inflation detection system
cannot warn of an incorrect pressure at
the time of reinitialisation.
The system must be reinitialised after any
adjustment of tyre pressures and after
changing one or more wheels.

The reinitialisation instruction is entered in
the screen menu, with the ignition on and the
vehicle stationary.
F Press repeatedly on the INFO button
to select "REINITIALISE" (located in

instrument panel) .

P
ress and hold the INFO button for at least
3 seconds to reinitialise the under-inflation
detection system.
Reinitialisation of the system is confirmed
by the flashing of the warning lamp in the
instrument panel. The under-inflation alert is only reliable
if the system has been reinitialised
with the four tyre pressures correctly
adjusted.
Operating fault
The flashing and then fixed illumination of the
under-inflation warning lamp accompanied by
the display of a message indicates a fault with
the system.
In this case, monitoring of the tyre pressures is
not assured.
This alert is also displayed if:
-

o
ne or more wheels is not fitted with a
sensor (spare wheel in use),
-

a w
ireless device operating on the same
frequency is close to the vehicle,
-

t
here are accumulations of snow or ice in
the wings or wheels,
-

t
he state of charge of the tyre pressure
monitoring system battery is too low,
-

t
he wheel sensor identifiers have not been
memorised in the system by a CITROËN
dealer or a qualified workshop. Any tyre repair or replacement on a
wheel fitted with this system must be
carried out by a CITROËN dealer or a
qualified workshop.
If you fit the second set of tyres
memorised in the system, a fault will
be signalled until the second set is
selected in the configuration menu. Go to a CITROËN dealer or a qualified
workshop
to have the system checked
or, following the repair of a puncture, to
have the original wheel, equipped with a
sensor, refitted.

Parking sensors
This function cannot, in any
circumstances, take the place of the
vigilance and responsibility of the driver.
Rear 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 due to
the presence of blind spots.
Audible assistance
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 approximately
thirty centimetres, the audible signal becomes
continuous.
The system is switched on by engaging reverse
gear. This is accompanied by an audible signal.
The indicator lamp in the button comes on to
confirm that the system is active.
The system is deactivated when you come out
of reverse gear.

Front parking sensors
Deactivation / Activation of the
front and rear parking sensors
The function is deactivated by pressing this
button. The indicator lamp in the button
goes off.
Pressing this button again reactivates the
function. The indicator lamp in the button
comes on.
Operating fault
The front parking sensors are triggered when
an obstacle is detected in front, a gear is
engaged (position D for vehicles with a CVT
gearbox) and the speed of the vehicle remains
below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than five seconds
in for ward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h). Remember to deactivate the system if
towing a trailer or caravan.In bad weather or in winter, ensure that
the sensors are not covered with mud,
ice or snow.
When the vehicle is moving at a speed
below 6 mph (10 km/h), certain sound
sources (motorcycle, lorry, pneumatic
drill, etc.) may trigger the audible
signals of the parking sensor system.
In the event of an problem, when reverse gear
is engaged this lamp in the button flashes,
accompanied by an audible signal.
This supplements the audible
signal by displaying bars in the
screen, in front of or behind
the vehicle.
If one of the sensors is faulty, it
flashes in the instrument panel
screen.
Contact a CITROËN dealer or a qualified
workshop.
These bars flash at the start of the manoeuvre
then become fixed from a certain distance
between the vehicle and the obstacle.

Reversing camera
Linked with the navigation option, the reversing
camera complements the parking sensor
system and is activated automatically when
reverse gear is engaged.The image from the camera is displayed in the
navigation screen.
The zone (A)


represents the upper part of the
rear bumper.
The red line represents the distance of 50 cm
from the edge of the rear bumper.
The green lines represent the width of the
vehicle increased by 20 cm on each side.
The marks on the green lines correspond to the
edges of the rear bumper (B), then the distance
of 1 metre from the edge of the rear bumper (C)
and 2 metres (D) . In no circumstances can the reversing
camera replace the need for vigilance
on the part of the driver.
Clean the reversing camera from time
to time using a soft dry cloth.
High pressure jet wash
When washing your vehicle, do not
direct the lance to within 30 cm of the
camera lens.

Automatic switching off
When the lighting control stalk is at "dipped or
main beam headlamps", if the ignition switch
is at "LOCK" or "ACC" or if the key has been
removed from the ignition switch, the lamps
switch off automatically when the driver's
door is opened .
Daytime running lamps
Daytime lighting which comes on automatically
when the engine is started making the vehicle
more visible to other users.
This function is assured by special lamps.
The lighting control stalk must be placed in
position "0" or "AUTO" (day mode).
Automatic illumination of headlamps
The sidelamps and the dipped beam headlamps
come on automatically, without any action on the
part of the driver, if a low level of exterior light is
detected or if the wipers are switched on.
When the light returns to a sufficient level or the
wipers are switched off, the lighting is switched off
automatically.
The sensor is located at the base of the windscreen.
Contact a CITROËN dealer or a qualified workshop
to adjust the sensitivity of the sensor.
