Lost keys
Go to 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 look up 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.
No remote control can 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 compartment by the
emergency services more difficult in an emergency.
As a safety precaution, never leave children alone in the vehicle, except for a very short
period.
In all cases, it is essential to remove the key from the ignition switch when leaving the vehicle.
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.Do not throw the remote control
batteries away, they contain metals
which are harmful to the environment.
Take them to an approved collection
point.

In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
F
T
o 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.
F

D
o not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the air conditioning system.
F

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

E
nsure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly.
W

e 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).
F

T
o 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.
F

I
f 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.
Recommendations for ventilation and air conditioning
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 & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section. The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.
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 compartment.
Contains fluorinated greenhouse gas R134A.
From 1st October 2016, depending on version and country of sale, contains fluorinated
greenhouse gas R134A (gas capacity 0.525 kg +/- 0.025 kg, GWP index 1 430, 0.751 t
equivalent CO
2). The air conditioning system does not
contain chlorine and does not present
any danger to the ozone layer.

are fitted with a 3rd fixing located in
the pedal area to avoid any risk of
inter ference with the pedals.
