Recommendations for ventilation and air conditioning


If after an extended stop in sunshine, the interior temperature is veryhigh, 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.
The air conditioning system does notcontain 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 wellas 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 monthto keep it in per fect working order. )
Ensure that the passenger compar tment 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 theoccupants 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 haveit checked regularly as recommended in the ser vicing booklet.
)
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 theair conditioning increases the available engine power and so improves the towing ability.


The condensation created by the air conditioning results in a dischargeof water under the vehicle which is perfectly normal.




Stop & Start
The heating and air conditioning systems only work when the engine is running. To maintaina comfor table temperature in the passenger compartment, you can temporarily deactivatethe Stop & Start system (see "Driving").

Do not throw the remote controlbatteries away, they contain metals which are harmful to the environment.
Take them to an approved collectionpoint.
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 toorder 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 haveto 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 theemergency services more difficult in an emergency. As a safety precaution (with children on board), remove the key from the ignition switchwhen 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 couldcause 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 star t the vehicle.

When immobilising the vehicle, withthe engine running, you must place thegear lever in neutral N
. Before carrying out any work in the engine compar tment, ensure that thegear lever is in neutral N
and that the parking brake is applied. Whatever the circumstances, you mustmanually apply the parking brake whenparking, unless the parking brake is programmed in automatic mode. Be
fore switching off the engine, you can:

In this case, the gearbox switches to back-up
mode and is locked in 3rd
gear. You may feel
a substantial knock when changing from Pto R
and from N
to R
. This will not cause any
damage to the gearbox.
Do not exceed 60 mph (10 0 km/h), local speed restrictions permitting.

is opened.
You risk damaging the gearbox:


- if you press the accelerator and brake pedals at the same time,

- if you force the lever from position Pto another position when the batteryis flat.
