Automatic day/night model
In order to guarantee optimum visibility
during your manoeuvres, the mirror lightens
automatically when reverse gear is engaged. By means of a sensor, which measures the
light from the rear of the vehicle, this system
automatically and progressively changes
between the day and night uses.
It has an anti-dazzle system which darkens the
mirror glass: this reduces any driver discomfort
caused by the light beam of following vehicles,
the sun...In vehicles fitted with electrochromatic door
mirrors, the system has an on/off button and an
associated warning lamp.

Ventilation
A. Sunshine sensor.
B. Soft air diffusion grille.
The soft air diffusion grille located in the
centre of the dashboard provides optimum
distribution of the air for the front seats.
This system eliminates unpleasant air
currents while maintaining an optimum
temperature in the passenger compartment.
To open the soft air diffusion grille, turn the
wheel upwards.
To close the soft air diffusion grille, turn the
wheel fully downwards.
In very hot weather, to obtain more
satisfactory central and side ventilation, it
is advisable to close the diffused air grille.
C. Cooled glove box.
D. Rear passenger vents.

We recommend use of the automatic regulation
of the air conditioning.
It permits automatic and optimised control
of all of the following functions: air flow,
temperature in the passenger compartment
and air distribution, by means of various
sensors (ambient temperature, sunshine).
This eliminates any need for you to change
your settings other than the temperature value
displayed.
F Take care not to cover the sunshine
sensor A.
If you select the automatic mode
(by pressing the "AUTO" control) and leave
all of the vents open, optimum comfort will be
maintained and humidity and condensation will
be removed regardless of the exterior climatic
conditions.
The temperature in the passenger compartment
can only be lower than the ambient temperature
if the air conditioning is on.
In order to be effective, the air conditioning must
be used with the windows closed. If the vehicle
has been parked in the sun for a long period
and the interior temperature is very high, first
ventilate the passenger compartment with the
windows open for a few minutes, then close the
windows.
Heating, ventilation and air conditioning recommendations
To keep the air conditioning system in
good working order it is essential that it is
operated at least once a month.
The air conditioning uses engine power
during its operation. As a result, the fuel
consumption of the vehicle increases.
In certain cases of particularly arduous use
(e.g. towing the maximum load on a steep
gradient in high temperatures), switching off
the air conditioning saves engine power and
improves the towing capacity.
Air inlet
Check that the exterior grille for the air inlet,
at the bottom of the windscreen, is clean and
free of dead leaves, snow, etc.
When washing the vehicle using a high
pressure nozzle, avoid spraying at the air
inlet. Maximum comfort is obtained by means of
a good distribution of air in the passenger
compartment, both in the front and in the rear.
To obtain a uniform distribution of air, take
care not to block the exterior air intake grille
located at the base of the windscreen, the
vents, the air outlets under the front seats and
the air extractor located behind the flaps in
the boot.
The front and rear vents are fitted with
thumbwheels to adjust the air flow and
direction. We recommend that you leave all of
the vents open.
Dust filter / Odour filter
(active carbon)
There is a filter for excluding odours and
dust.
This filter must be changed in line with the
vehicle's servicing schedule. (Refer to the
maintenance and warranty guide).

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.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. 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 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.
Driving with under-inflated tyres
increases fuel consumption.
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.
Maintenance
Before doing any work under the
bonnet, deactivate the Stop & Start
system to avoid the risk of injury related
to an automatic change to START
mode.
This system requires the use of a 12 V battery
of specific technology and characteristics
(reference numbers available from a CITROËN
dealer or a qualified workshop).
Fitting a battery not listed by CITROËN would
introduces the risk of faults with the system.
The Stop & Start system makes use of
an advanced technology. All work on
this type of battery must only be carried
out by a CITROËN dealer or a qualified
workshop.

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 tyre or
tyres concerned is reinflated, repaired
or replaced.
The spare wheel (space-saver type or a
steel rim) does not have a sensor.
Under-inflation alert
The aler t 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.
F
Reduce speed, avoid sudden steering
movements or harsh brake applications.
F Stop as soon as it is safe to do so. F
If you have a compressor (the one in the
temporary puncture repair kit for example),
check the four tyre pressures when cold.
If it is not possible to check the tyre
pressures at the time, drive carefully at
reduced speed.
or
F In the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (according to equipment).
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.
In this case, monitoring of the tyre pressures is
not assured.
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).
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.
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.

Lane departure warning system
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.
Deactivation
F Press this button again, the indicator lamp
goes off.
The status of the system remains in the
memory when the ignition is switched off.
Detection
You are warned by the vibration of the driver's
seat cushion:
- on the right-hand side, if the marking on
the ground has been crossed on the right,
- on 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.
Operating fault
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.
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)).
The detection may be impeded:
- if the sensors are dirty (mud, snow...),
- if the markings on the ground are
worn,
- if there is little contrast between the
markings on the ground and the road
sur face.
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.

Parking space sensors
System which measures the parking space
available between two vehicles or obstacles. It
measures the size of the space and gives you
information on:
- the possibility of fitting into a free space,
depending on the dimensions of your
vehicle and the distances necessary for
your manoeuvres,
- the level of difficulty of the manoeuvre to
be performed.
The system does not measure spaces which
are clearly much smaller or larger than the size
of the vehicle. The parking space sensor system warning
lamp can have three different states:
-
off: the system is not selected,
- on fixed: the system is selected but the
conditions for measuring are not yet met
(direction indicator not operating, speed too
high) or the measurement is terminated.
- flashing: measurement is in progress or
the message is being displayed. You can select the "parking space sensor"
system by pressing button A
. The fixed
illumination of the warning lamp indicates that
the system is selected.
During the measurement, the message
"Measurement in progress - Vmax 20 km/h
(12 mph)" is displayed in the instrument panel
screen.Displays in the instrument panel

Operation
You have identified a parking space:
F Press button A to select the system.
F Activate the direction indicator on the side
where the space is to be measured.
F During measurement, go for ward the
length of the space, at a speed less than
12 mph (approx. 20 km/h), to prepare for
your manoeuvre.
The system then measures the size of the space.
F The system informs you of the level
of difficulty of the manoeuvre via a
message in the instrument panel screen
accompanied by an audible signal.
F Depending on the message issued by the
system, you may or may not be able to
per form the manoeuvre.The system displays the following types of message:
Parking YES
Parking DIFFICULT
Parking NO The system is deselected automatically:
-
when you engage reverse gear,
- when you switch off the ignition,
- if measurement is not requested,
- within five minutes of selection of the
system,
- if the vehicle speed exceeds the
threshold of 45 mph (approx. 70 km/h) for
one minute.
If the lateral distance between your vehicle and
the parking space is too large, the system may
not be able to measure the space.
The system remains available after each
measurement and thus can measure more than
one space during your search.
In bad weather conditions or in winter, make
sure that the sensors are not covered by dirt, or
by ice or snow.
The parking space sensor system deactivates
the front parking sensors during space
measurement when you are in for ward gear.
If there is a fault, have the system
checked by a CITROËN dealer or a
qualified workshop.

Parking sensors
Operation
The parking sensors system cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
This system detects any obstacle (person,
vehicle, tree, barrier...) located in front of or
behind the vehicle, however, it will not be able
to detect obstacles located immediately below
the bumper.
An object, such as a stake, a roadworks cone
or any other similar object may be detected at
the start of the manoeuvre but may no longer
be detected when the vehicle moves nearer
to it.
At the front and/or at the rear
This system is comprised of proximity sensors,
installed in the front and/or rear bumper.
Visual and audible assistance
The proximity information is indicated by:
-
an audible signal which becomes more rapid
as the vehicle approaches the obstacle,
- a diagram in the multifunction screen, with
blocks which move closer to the vehicle.
The obstacle is located in relation to the emission
of the audible signal by the speakers; front or rear
and right or left.
When the distance between the vehicle and
the obstacle is less than approximately thirty
centimetres, the audible signal becomes
continuous and/or the "Danger" symbol appears,
depending on the multifunction screen version.
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.
When the speed of the vehicle is below
about 6 mph (10 km/h), some sources
of noise (motorcycle, lorry, pneumatic
drill, ...) may trigger the audible parking
sensor signals. The parking sensors are switched on
:
- by engaging reverse gear,
- at a speed below 6 mph (10 km/h) in
forward gear.
This is accompanied by an audible signal and
the display of the vehicle in the multifunction
screen.
The parking sensors are switched off :
- when you exit reverse gear,
- when the speed is higher than 6 mph
(10 km/h) in for ward gear,
- when the vehicle has been stationary for
more than three seconds in for ward gear.
