Citroen C4: Refuelling

Fuel tank capacity: approximately 50 litres.

Reserve level: approximately 6 litres.

Low fuel level

When the low fuel level is reached, this warning lamp lights up on the instrument panel, accompanied by the display of a message and an audible signal. When it first comes on, about 6 litres of fuel remain.

Until sufficient fuel is added, this warning lamp appears every time the ignition is switched on, accompanied by the message and the audible signal. When driving, this message and audible signal are repeated with increasing frequency as the fuel level drops towards 0.

You must refuel as soon as possible to avoid running out of fuel.

For more information on Running out of fuel (Diesel), refer to the corresponding section.

A small arrow by the warning lamp indicates which side of the vehicle the fuel filler flap is located on.

Stop & Start / e-Auto mode

Never refuel with the engine in STOP mode or in stand-by; you must switch off the ignition.

Refuelling

When refuelling, at least 5 litres must be added in order to be registered by the fuel gauge.

Opening the filler cap may create a noise caused by an inrush of air. This vacuum is normal, caused by the sealing of the fuel system.

To refuel in complete safety:

► Always switch off the engine.

► With the vehicle unlocked, press the rearcentral part of the filler flap to open it.

► Take care to select the pump that delivers the correct fuel type for your vehicle's engine (see a reminder label on the inside of the filler flap).

► Turn the filler cap to the left, remove it and place it on its support (on the filler flap).

► Insert the filler nozzle and push it in as far as possible before starting to refuel (to minimise the risk of splashing).

Do not continue after the nozzle's third cutout.

Doing so may cause malfunctions.

► Put the filler cap back in place and turn it to the right.

► Close the fuel filler flap.

If you have put in the wrong fuel for the vehicle, you must have the fuel tank drained and filled with the correct fuel before starting the engine.

The vehicle is fitted with a catalytic converter, which helps to reduce the level of harmful emissions in the exhaust gases.

For petrol engines, you must use unleaded fuel.

The filler neck is narrower, admitting unleaded petrol nozzles only.

Misfuel prevention (Diesel)

(Depending on country of sale.)

This mechanical device prevents filling the tank of a Diesel vehicle with petrol.

Located in the filler neck, the misfuel prevention device is visible when the filler cap is removed.

Operation

When a petrol filler nozzle is introduced into the fuel filler neck of a 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.

The misfuel prevention device does not prevent filling with a jerrycan, regardless of the fuel type.

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, it is advisable to check with a CITROËN dealer if the vehicle is suitable for the distribution equipment of the countries visited.
