Automatic operation
1. Automatic comfort programme
We recommend the use of one of
the three AUTO modes available:
they provide optimised regulation of
the temperature in the passenger compartment according to the comfort value
that you have chosen.
These three modes automatically adjust the
air flow, according to the desired setting, while also maintaining the desired comfort value.
) Press the "AUTO"
button repeatedly:


- a first indicator lamp comes on; the
"li
ght" setting mode is selected,

- a second indicator lamp comes on; the"medium" setting mode is selected,

- a third indicator lamp comes on; the
"intense" mode setting is selected.

When the engine is cold, the air flow will reach its optimum level
progressively, taking account of the weather and the desired comfort levelso as to avoid too great a distributionof cold air. On entering the vehicle, if the interior temperature is much colder or warmer than the comfort value, there is noneed to change the value displayed in order to obtain the comfor t required.The system corrects the differencein temperature automatically and asquickly as possible.
This s
ystem is designed to operate effectivelyin all seasons, with the windows closed.

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.
