Practical information

Fuel

Capacity of the tank: approximately 60 litres.

Low fuel level

Refuelling

When the low fuel level in the

Additions of fuel must be of at least 5 litres to

tank is reached, this warning lamp

comes on in the instrument panel,

accompanied by an audible warning

and the display of an alert message.

When it first comes on, around

6 litres of fuel remain in the tank.

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.

Until sufficient fuel has been added, every time

the ignition is switched on, this warning lamp

appears, accompanied by an audible signal

and an alert message. When driving, this

audible signal and alert message are repeated

with increasing frequency, as the level drops

towards 0.

You must refuel as soon as possible to avoid

running out.

For more information on Running out of fuel

(Diesel), refer to the corresponding section.

F

Press this button until the automatic

opening of the fuel flap is heard.

This button remains active for a few

minutes after switching off the ignition. If

necessary, switch the ignition on again to

reactivate it.

Take care to select the pump that delivers

the correct fuel for your vehicle.

If your vehicle is fitted with Stop &

Start, never refuel with the engine in

STOP mode; you must switch off the

ignition using the key, or the START/

STOP button if your vehicle has

Keyless Entry and Starting.

Practical information

Fuel supply cut-off

Your vehicle is equipped with a safety device

which cuts off the fuel supply in the event of a

collision.

If you are filling your tank to the top, do not

persist after the third cut-off; this could

cause your vehicle to malfunction.

The petrol or Diesel engine of your vehicle is

fitted with a catalytic converter, a device which

helps to reduce the level of harmful emissions

in the exhaust gases.

For petrol engines, the use of unleaded fuel

is compulsory.

The filler neck is narrower, admitting unleaded

petrol nozzles only.

F

Introduce the nozzle so as to push in the

metal non-return flap.

Make sure that the nozzle is pushed in as

far as possible before starting to refuel (risk

of blowback).

Maintain this position while refuelling.

Push the fuel flap to close it.

If you have put in the wrong fuel for

your vehicle, you must have the tank

drained and refilled with the correct

fuel before you start the engine.

Practical information

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.

Operation

It remains possible to use a fuel can to

fill the tank.

Travelling abroad

As Diesel fuel pump nozzles may

be different in other countries, the

presence of the misfuel prevention

device may make refuelling impossible.

Not all Diesel vehicles are fitted with

misfuel protection, so 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

intend to travel.

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

slowly.

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.

engines

The Diesel engines are compatible with

biofuels that conform to current and future

European standards and can be obtained from

filling stations:

The use of B20 or B30 fuel

meeting standard EN16709

is possible in your Diesel

engine. However, this use,

even occasional, requires

strict application of the special

servicing conditions referred to as

"Arduous conditions".

-

Petrol that meets the EN228

standard, mixed with a bio-

fuel meeting the EN15376

standard.

-

Diesel fuel that meets

standard EN590 mixed

with a biofuel that meets

standard EN14214 (possibly

containing up to 7 % Fatty

Acid Methyl Ester),

For more information, contact a CITROËN

dealer or a qualified workshop.

Diesel fuel that meets

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).

standard EN16734 mixed

with a biofuel that meets

standard EN14214 (possibly

containing up to 10 % Fatty

Acid Methyl Ester),

The only petrol additives authorised

for use are those that meet

the B715001 standard.

Travelling abroad

Certain fuels could damage the

engine of your vehicle. In certain

countries, the use of a particular

fuel may be required (specific

octane rating, specific sales

name…) to ensure correct operation

of the engine.

-

Paraffinic Diesel fuel that

meets standard EN15940

mixed with a biofuel that

meets standard EN14214

(possibly containing up to 7 %

Fatty Acid Methyl Ester).

The only Diesel additives authorised

for use are those that meet

the B715000 standard.
