This strap cannot apply the parking brake. To re-engage the electronic parking brake (after resolution of the malfunction or the fl at battery), make a long pull on the control lever A until the parking brake warning lamp (!) fl ashes on the instrument panel then make a second long pull until this warning lamp remains lit permanently. The time for applying the brake subsequent to the emergency unlocking will be longer.
2. Fetch the vehicle block located in the boot.3. Immobilise the vehicle by placing the block in front of or behind one of the rear wheels.4. Open the lower compartment of the central armrest by pulling upwards.5. Ensure that the cup-holder B is Bfolded back.6. Remove the rubber mat covering the base of the armrest.7.

The ESP system offers increased driving safety but is not in place to encourage the driver to take addi-tional risks or to drive at excessive speeds.
The functioning of this system is subject to compliance with the manufacturer’s recommendations on wheels (tyres and rims), brake parts and electronic components, as well as with the assembly and repair procedures approved by CITROËN.repair procedures repair procedures
After any collision, contact a CITROËN dealer.
Electronic Stability Programme (ESP) and Traction Control (ASR)
These systems are closely associated with ABS and additional to it. In the event of a loss of control of the vehicle by the driver, the ESP system acts automatically on one or more wheels and also on the engine to bring the vehicle back on trajectory. The ASR system optimises traction and prevents wheel spin by acting on the brakes of the driving wheels as well as on the engine. It also improves steering stability during acceleration.
Operation
If either of the ESP or ASR systems is active, the warning lamp fl ashes.
Deactivation
In exceptional conditions (vehicle stuck in snow, soft ground, e tc.) it may prove useful to deactivate the ESP/ASR systems to allow the wheels to spin and thus regain traction.
Press on control A, the warning lamp and the light on control A light up. The ESP/ASR systems are no longer active.
The ERSP/ASR systems will activate again:Automatically after the ignition has been switched off.
Automatically when you drive at above approx. 50 km/h (approx. 30 mph).
Manually with another press on button A.
Operational anomaly
If there is a system fault, the warning lamp lights up, accompa nied by a message on the instrument panel screen, the lighting of the SERVICEwarning lamp and a beep.
Contact a CITROËN dealer to have the system checked.

You are advised to use the automatic air conditioning regulation. This automatically regulates the following functions for maximum comfort : air fl ow, passenger compartment temperature, and air distribution, using different sensors (external temperature, sunlight). This avoids the need to alter any of the settings, with the exception of the temperature displayed.
Take care not to obstruct the sunlight sensor A.
Provided you retain automatic mode (by pressing button “AUTO”) and all the air vents are open, you will main-tain an optimum comfort level, also removing humidity and misting, whatever the ambient climatic conditions.
The temperature inside the cabin cannot be lower than the temperature outside if the air conditioning is not operating.
To be effective, the air conditioning should only be used with the windows closed. If after a lengthy stop in bright sunlight the interior temperature is excessive, air the passenger compartment by opening the windows for a few moments, then close them again.
To ensure the correct operation of the air conditioning system, it is essential to operate the air conditioning at least once a month.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel con-sumption.
In certain extreme operating conditions (e.g. carrying a full load up a steep gradient in high temperatures), the switching off of the air conditioning allows more power to be transferred to the engine, thereby increasing the towing capacity.
Air inlet
Check that the exterior grille for the air inlet, at the bot-tom of the windscreen, is clean and free of dead leaves, snow, etc.
If washing the vehicle with a high pressure jet, avoid targeting the air inlet zone.
Air circulation
For your comfort we advise you to maintain a proper distribution of air within the cabin, both at the front and at the rear.
To obtain an even distribution of air, ensure that you do obstruct the external air inlet grille located at the base of the windscreen, the air vents, the air outlets on the fl oor underneath the front seats, and the air extractor located behind the fl aps in the boot.
The front and rear air vents are fi tted with control knobs which allow you to control and direct the air fl ow. It is recommended to keep all the air vents open.
Dust/pollen fi lter
There is a fi lter for excluding pollen and dust.
This fi lter has to be changed according to the vehicle maintenance schedule. See “Maintenance Guide”.

If the battery is discharged, it is possible to use either a separate emergency battery or a battery on another vehicle.A. Dischargedbattery (Under the bonnet).B. Assisting battery.
Check that the assisting battery has suffi cient voltage (12 V).
If you use the battery on another vehicle, stop the engine on the latter. The two vehicles must not come into direct contact with each other.
Connect the cables according to the order indicated in the diagram. Check orderthat the leads are well secured (risk of sparks).
Start the engine of the assisting vehicle. Let the engine run for around 1 minute at a slightly accelerated idle.
