Fuel tank
Capacity of the tank: approximately 71 litres*.
Low fuel level
When the minimum 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
multifunction screen. When it first comes on,
there remains around 5 litres of fuel in the tank.
You must refuel to avoid running out of fuel.

to malfunction.
While you are refuelling, the engine must be
stopped and the ignition switched off.
For a petrol engine with a catalytic
converter, unleaded fuel is compulsory.

* 55 litres for Slovakia. Additions of fuel must be of at least
5 litres to be taken into account by the
fuel gauge.
The filler neck is narrower to ensure
that only unleaded petrol nozzles can
be put in.
Opening the filler cap may create a
noise of an inrush of air. This vacuum,
which is entirely normal, is caused by
the sealing of the fuel system.
With Stop & Start, never refuel with the
system in STOP mode; you must switch
off the ignition with the key.

Misfuel prevention (Diesel)*
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.
* According to country of sale. 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.
Operation
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

Fuel used for petrol
engines
The petrol engines are compatible with
E10 bio-petrol (containing 10 % ethanol),
conforming to European standards EN 228
and EN 15376.
E85 type fuels (containing up to 85 % ethanol)
are reserved exclusively for vehicles marketed
for the use of this type of fuel (BioFlex
vehicles). The quality of the ethanol must
comply with European standard EN 15293.
Fuel used for Diesel
engines
The Diesel engines are 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).
B30 biofuel can be used in certain Diesel
engines. However, this use, even occasional,
requires 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).
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.

For any work on your vehicle, contact
a qualified workshop that has the
skills and equipment required, which a

If the engine fails to start at the first attempt,
wait fifteen seconds before trying again.
If the engine fails to start after a few attempts,
operate the priming pump again and then try to
start the engine.
When the engine is idling, accelerate slightly to
complete the bleeding of the circuit.

Temporary puncture repair kit
The kit is located in the boot under the floor.
Complete system consisting of a compressor
and a sealant cartridge which permits the
temporary repair
of the tyre so that you can
drive to the nearest garage. This repair kit is available from
CITROËN dealers or a qualified
workshop.
It is designed to repair holes of a
maximum diameter of 6 mm, located
exclusively on the tyre tread or
shoulder. Avoid removing any foreign
bodies which have penetrated the tyre.
The vehicle's electric system allows the
connection of a compressor for long
enough to inflate a tyre after a puncture
repair or for inflating a small inflatable
accessory.
