Switching onSwitching off
F Press the open padlock on the
remote control or one of the front
door handles with the "Keyless
Entry and Starting" system.
The sidelamps and dipped beam headlamps,
as well as the side spotlamps, located under
the door mirrors, come on; your vehicle is also
unlocked. Activation or deactivation, as well as
the duration of the lighting duration
for the welcome lighting can be set
via the vehicle configuration menu.
Programming
The welcome lighting switches off automatically
after a programmed time, when the ignition is
switched on or on locking the vehicle.
Visibility

Automatic rain sensitive
windscreen wipers
The windscreen wipers operate automatically,
without any action on the part of the driver,
if rain is detected (sensor behind the rear view
mirror), adapting their speed to the intensity of
the rainfall.
Switching on
Briefly push stalk A downwards.The instruction is confirmed by
a wiping cycle, accompanied by
illumination of this warning lamp
in the instrument panel and an
activation message.
Switching off
Briefly push stalk A downwards again.
The instruction is confirmed by
this warning lamp going off in the
instrument panel and/or the display
of a deactivation message.
The automatic rain sensitive
windscreen wipers must be reactivated
if the ignition has been off for more
than one minute.
Operating fault
If an automatic rain sensitive wiper malfunction
occurs, the wipers will operate in intermittent
mode.
Contact a CITROËN dealer or a qualified
workshop. Do not cover the rain sensor, linked with
the sunshine sensor and located in the
centre of the windscreen behind the rear
view mirror.
Switch off the automatic rain sensitive
wipers when using an automatic car wash.
In winter, it is advisable to wait until the
windscreen is completely clear of ice
before activating the automatic rain
sensitive wipers.

Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert if a drop in
pressure is detected in one or more tyres.Driving with under-inflated tyres
increases fuel consumption.The tyre pressures for your vehicle
can be found on the tyre pressure
label (see the "Identification markings"
section).
The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Other wise, add 0.3 bar to the values
indicated on the label.
This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
The tyre under-inflation detection system is an
aid to driving which does not replace the need
for vigilance on the part of the driver.

2 11
Under-inflation alert
The loss of pressure detected does
not always lead to visible deformation
of the tyre. Do not rely on just a visual
check.This alert is also displayed when one or
more wheels is not fitted with a sensor
(for example, a space-saver or steel
spare wheel).
The alert is maintained until the tyre or
tyres concerned is reinflated, repaired
or replaced.
The spare wheel (space-saver type or
a steel rim) does not have a sensor.
The alert is given by the fixed illumination
of this warning lamp, accompanied by
an audible signal, and depending on
equipment, the display of a message.
In the event of a problem on one of the tyres,
the symbol or the message appears, according
to equipment, to identify it.

Operating fault
The flashing and then fixed
illumination of the under-inflation
warning lamp accompanied by the
illumination of the service warning
lamp indicates a fault with the system.
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.

n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (according to equipment).
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 after changing a tyre, a wheel is not detected
by your vehicle (fitting snow tyres for example),
you must have the system reinitialised by a
CITROËN dealer or a qualified workshop. In this case, monitoring of the tyre pressures is
not assured.
driving

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
driver.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 function cannot, in any circumstances,
take the place of the vigilance 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.
driving

Front parking sensorsOperating fault
In the event of a malfunction of the
system, when reverse gear is engaged
this warning lamp is displayed in the
instrument panel and/or a message
appears in the screen, accompanied
by an audible signal (short beep).
Contact a CITROËN dealer or a
qualified workshop.
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 no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).
The function will be deactivated
automatically if a trailer is being towed
or a bicycle carrier is fitted (vehicle
fitted with a towbar or bicycle carrier
recommended by CITROËN).In bad weather or in winter, ensure
that the sensors are not covered with
mud, ice or snow. When reverse gear is
engaged, an audible signal (long beep)
indicates that the sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking
sensor system.deactivation/Activation of the
front and rear parking sensors
The function is deactivated by pressing this button.
The indicator lamp in the button comes on.
Pressing this button again reactivates the function.
The indicator lamp in the button goes off.
The sound emitted by the speaker
(front or rear) indicates whether the
obstacle is in front or behind.
