Recommendations for ventilation and air conditioning


If after an extended stop in sunshine,
the interior temperature is very
high, first ventilate the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in
the passenger compar tment.
The air conditioning system does not
contain chlorine and does not present
any danger to the ozone layer. In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:


)
To obtain an even air distribution, take care not to obstruct the exterior air intake grilles
located at the base of the windscreen, the nozzles, the vents and the air outlets, as well
as the air extractor located in the boot.

)
Do not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the digital air conditioning system.

)
Operate the air conditioning system for at least 5 to 10 minutes, once or twice a month
to keep it in per fect working order.

)
Ensure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly (refer to the "Checks" section).
We recommend the use of a combined passenger compartment filter. Thanks to its
special active additive, it contributes to the purification of the air breathed by the
occupants and the cleanliness of the passenger compartment (reduction of allergic
symptoms, bad odours and greasy deposits).

)
To ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly as recommended in the Maintenance and Warranty Guide.

)
If the system does not produce cold air, switch it off and contact a CITROËN dealer or a
qualified workshop.
When towing the maximum load on a steep gradient in high temperatures, switching off the
air conditioning increases the available engine power and so improves the towing ability.
The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.




Stop & Start

The heating and air conditioning systems only work when the engine is running. To maintain
a comfortable temperature in the passenger compartment, you can temporarily deactivate
the Stop & Star t system (see "Driving").

Switching the system off



)
Turn the air flow control to
the left until all of the indicator
lamps go off.
This switch does not operate the air conditioning, only the air fan.
When the "REST" function is activated, you cannot modify the temperature, air flow
and distribution settings: these are controlled automatically according to the ambient
temperature.
This function is not available in the STOP mode of Stop & Start.
Avoid prolonged operation in interior
air recirculation mode or driving for
long periods with the system off (risk of
condensation and deterioration of air
quality).
On switching on the engine



- The control screens come on: the function
is available.

- Pressing the REST
button activates the
ventilation for a few minutes. Activation of
the function is confirmed by the display of
two dashes in the control screens and four
air flow level indicator lamps.

- The function can be deactivated and
reactivated if the control screens are on.

- The screens go off at the end of this period.
On stopping the engine



- While the control screens remain on: the
function is available.

- Pressing the REST
button activates the
ventilation for a few minutes. Activation of
the function is confirmed by the display of
two dashes in the control screens and four
air flow level indicator lamps.
Locking the vehicle has no effect on this
function.

- The control screens go off at the end of
this period.
Pressing again before the end of the period
interrupts off the ventilation definitively: the
control screens go off and the function is
no longer available. This action switches off the air conditioning and
the ventilation.
Temperature related comfor t is no longer
assured but a slight flow of air, due to the
movement of the vehicle, can still be felt.


)
Modify the settings (temperature, air flow or
air distribution) or press the "AU TO "
button
to reactivate the system with the values set
before it was switched off.

Front demist - defrost


These markings on the control panel indicate the control positions for rapid demisting or
defrosting of the windscreen and side windows.


With manual air
conditioning

the "A /C "
button; the warning lamp in the
button comes on.



With digital dual-zone air
conditioning

With Stop & Star t, when the demisting,
air conditioning and air flow functions
are activated, STOP mode is not
available.


Automatic visibility programme



)
Select this programme to demist or defrost
the windscreen and side windows as
quickly as possible.
The system automatically manages the air
conditioning, air flow and air intake, and
provides optimum distribution towards the
windscreen and side windows.


)
To stop the programme, press either the
"visibility"
button again or "AU TO "
, the
warning lamp on the button goes off and
the warning lamp on the "AU TO "
button
comes on.
The system starts again with the values in
use before it was overridden by the visibility
programme.






With Stop & Star t, when demisting has
been activated, the STOP mode is not
available.

Starting the vehicle



)
Inser t the key in the ignition switch.
The system recognises the star ting code.

)
Turn the key fully towards the dashboard to
position 3 (Star ting)
.

)
When the engine star ts, release the key.


)
Immobilise the vehicle.

)
Turn the key fully towards you to
position 1 (Stop)
.


)
Remove the key from the ignition switch.



Switching the vehicle off


A heavy object (key fob...), attached to
the key and weighing down on its shaft
in the ignition switch, could cause a
malfunction.











Key left in the "Ignition on"
position
On opening the driver's door, an aler t
message is displayed, accompanied
by an audible signal, to remind you that
the key is still in the ignition switch at
position 1 (Stop)
.
If the key has been left in the ignition
switch at position 2 (Ignition on)
,
the ignition will be switched off
automatically after one hour.
To switch the ignition back on, turn the
key to position 1 (Stop)
, then back to
position 2 (Ignition on)
.

Do not throw the remote control
batteries away, they contain metals
which are harmful to the environment.
Take them to an approved collection
point.













Lost keys

Visit a CITROËN dealer with the vehicle's registration document, your personal
identification documents and if possible the key code label.
The CITROËN dealer will be able to find the key code and the transponder code required to
order a new key.


Remote control

The high frequency remote control is a sensitive system; do not operate it while it is in your
pocket as there is a possibility that it may unlock the vehicle, without you being aware of it.
Do not repeatedly press the buttons of your remote control out of range and out of sight of
your vehicle. You run the risk of stopping it from working and the remote control would have
to be reinitialised.
The remote control does not operate when the key is in the ignition switch, even when the
ignition is switched off, except for reinitialisation.


Locking the vehicle

Driving with the doors locked may make access to the passenger compar tment by the
emergency services more difficult in an emergency.
As a safety precaution (with children on board), remove the key from the ignition switch
when you leave the vehicle, even for a shor t time.


Anti-theft protection

Do not make any modifications to the electronic engine immobiliser system; this could
cause malfunctions.


When purchasing a second-hand vehicle

Have the pairing of all of the keys in your possession checked by a CITROËN dealer,
to ensure that only your keys can be used to open and start the vehicle.

149Fittings
230 V/50 Hz power
socket

A 230 V/50 Hz socket (maximum power: 120 W)
is fitted to the centre console.
To use the socket:


)
lift the front armrest cover for access to its
compartment,

)
check that the warning lamp is on green,

)
connect your multimedia or other electrical
device (telephone charger, laptop computer,
CD-DVD player, baby food warmer...).
This socket works with the engine running, as
well as in STOP mode on Stop & Start.
In the event of a fault with the socket, the green
warning lamp flashes.
Have it checked by a CITROËN dealer or a
qualified workshop.
Connect only one device at a time to
the socket (no extension or multi-way
connector).
Connect only devices with class II
insulation (shown on the device).
As a safety measure, when electrical
consumption is high and when
required by the vehicle's electrical
system (particular weather conditions,
electrical overload...), the current
supply to the socket will be cut off;
the green warning lamp goes off.







12 V accessory
socket


)
To connect a 12 V accessory
(max power: 120 W), lift the cover and
connect a suitable adaptor.

Stopping the vehicle
Operating fault

With the ignition on, the flashing of AUTO
,
accompanied by an audible signal and a
message in the multifunction screen, indicates
a malfunction of the gearbox.
Have it checked by a CITROËN dealer or a
qualified workshop.

You must press the brake pedal when
starting the engine.
Whatever the circumstances, you must
manually apply the parking brake when
parking, unless the parking brake is
programmed in automatic mode.

When immobilising the vehicle, with
the engine running, you must place the
gear lever in neutral N
.
Before carrying out any work in the
engine compar tment, check that the
gear lever is in neutral N
and that the
parking brake is applied.
Before switching off the engine, you can
choose to:


- move to position N
to engage neutral,

- leave the gear engaged; in this case, it will
not be possible to move the vehicle.
In both cases, you must apply the parking
brake to immobilise the vehicle.

Stop & Start
The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The
engine restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.


Operation


Going into engine STOP mode

With the electronic gearbox system,
for your comfort during parking
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as
braking, power steering, for example.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key. The "ECO"
warning lamp comes
on in the instrument panel and the
engine goes into standby:


- with a manual gearbox
, at speeds below
12 mph (20 km/h), when you put the gear
lever into neutral and release the clutch
pedal,

- with the 6-speed electronic gearbox
system
, at a speed below 5 mph (8 km/h),
when you press the brake pedal or put the
gear lever into position N
.
If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP
mode during a journey. It resets
itself to zero every time the ignition
is switched on with the key. STOP mode is not invoked when:


- the driver's door is open,

- the driver's seat belt is not fastened,

- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine star t
using the key,

- the electric parking brake is applied or
being applied,

- the engine is needed to maintain a
comfor table temperature in the passenger
compartment,

- demisting is active,

- some special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.


Special cases: STOP mode
unavailable
In this case, the "ECO"
warning lamp
flashes for a few seconds, then goes
off.

This operation is per fectly normal.
