Fuel tank Capacity of the tank: approximately 60 litres.
Additions of fuel must be of at least 5 litres to be registered by the fuel gauge. Opening the filler cap may result in an inrush of air. This vacuum is entirely normal and results from the sealing of the fuel system.  Take care to select the pump that delivers the correct fuel type for your vehicle's engine (reminder on a label on the inside of the filler flap).  Open the filler cap by turning it a 1/4 turn to the left.  Remove the filler cap and hang it on its carrier (on the filler flap).
Opening
If you have put in the wrong fuel for your vehicle, you must have have the tank drained and refilled with the correct fuel before you star t
the engine.
With Stop & Start, never refuel with the system in STOP mode; you must switch off the ignition with the START/STOP button.
Refuelling
 Introduce the nozzle and push it in fully (pushing open the metal non-return valve A ). A ). A

Your vehicle is fitted with a catalytic converter that reduces the levels of harmful substances in the exhaust gas.
 Press the switch . This switch remains active for a few minutes after switching off the ignition. If necessary, switch the ignition on again to reactivate it.

Low fuel level
When the low fuel level in the tank is reached, this warning lamp comes on in the instrument panel, accompanied by an audible warning and a message in the instrument panel screen.
Fuel supply cut-off
Your vehicle is equipped with a safety device which cuts off the fuel supply in the event of a
collision.
It remains possible to use a fuel can to fill the tank. In order to ensure a good flow of fuel, do not place the nozzle of the fuel can in direct contact with the flap of the misfuel prevention device and pour
s l ow l y.
Misfuel prevention (Diesel) *
Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of engine damage that can result from filling with the wrong fuel. Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
When a petrol filler nozzle is introduced into the fuel filler neck of your Diesel vehicle, it comes into contact with the flap. The system remains closed and prevents filling. Do not persist but introduce a Diesel type filler nozzle.
Operation
Travelling abroad
As Diesel fuel pump nozzles may be different in other countries, the presence of the misfuel prevention device may make refuelling impossible. Before travelling abroad, we recommend that you check with the CITROËN dealer network, whether your vehicle is suitable for the fuel pumps in the country in which you want to travel.
* According to country of sale.
When it first comes on, around 6 litres of fuel remain in the tank. Until sufficient fuel has been added, this warning lamp comes on every time the ignition is switched on, accompanied by an audible signal and a message. This audible signal and message are repeated with increasing frequency as the fuel levels drops and approaches "0". You must refuel as soon as possible to avoid running out.

Quality of the fuel used for
Diesel engines
The Diesel engines are per fectly compatible with biofuels which conform to current and future European standards (Diesel fuel which complies with standard EN 590 mixed with a biofuel which complies with standard EN 14214) available at the pumps (containing up to 7 % Fatty Acid Methyl Ester). The B30 biofuel can be used in certain Diesel engines; however, this use is subject to strict application of the special servicing conditions.
Contact a CITROËN dealer or a qualified workshop. The use of any other type of (bio)fuel (vegetable or animal oils, pure or diluted, domestic fuel...) is strictly prohibited (risk of damage to the engine and fuel system).

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. You can switch off the air conditioning (AC button) and stay in Automatic mode in order to limit fuel consumption. If misting appears while in this mode, you can switch the air conditioning back on temporarily to improve the situation. 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
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. The air conditioning system does not contain chlorine and does not present any danger to the ozone layer.
The condensation created by the air conditioning results in a discharge of water under the vehicle which is per fectly normal.

Dual-zone digital air conditioning
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 control the system, according to the desired setting, while also maintaining the desired comfort value.
 Press the "AUTO" button repeatedly: - a first indicator lamp comes on; the "low" setting mode is selected, - a second indicator lamp comes on; the "medium" setting mode is selected, - a third indicator lamp comes on; the "high" mode setting is selected. Use the "medium" and "high" settings in preference to maintain the comfort level at the r e a r.
When the engine is cold, the air flow will reach its optimum level progressively, taking account of the weather and the desired comfort level so as to avoid too great a distribution of cold air. On entering the vehicle, if the interior temperature is much colder or warmer than the comfort value, there is no need to change the value displayed in order to obtain the comfort required. In all seasons, with the windows closed the system corrects the difference in temperature automatically and as quickly as possible.
This system is designed to operate effectively
in all seasons, with the windows closed.
Automatic operation
The air conditioning can only operate when the hybrid system is active (Ready lamp on). Its effectiveness will be reduced when in electric mode (see the ECO OFF section).
