2011.5 Citroen DS4 RHD fuel pump

Fuel tank Capacity of the tank: approximately 60 litres.
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 the display of an aler t message. When it first comes on, around 6 litres of fuel remain
in the tank.
Until sufficient fuel has been added, every time
the ignition is switched on, this warning lampappears, accompanied by an audible signal and an aler t message. When driving, this audiblesignal and the display of this aler t message are repeated with increasing frequency, as the level
drops towards 0 .
You must refuel as soon as possible to avoid
running out.
If you run out of fuel (Diesel), refer also to
"Checks".


Refuelling
)Press control A
until the automatic openingof the fuel flap is heard.
This control 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.
With Stop & Star t, never refuel with the system in STOP mode; you must switch off the ignition with the key. 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.

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 cer tain Dieselengines; however, this use is subject to strictapplication of the special ser vicing 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).


















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

It remains possible to use a fuel can tofill the tank.In order to ensure a good flow of fuel, do not place the nozzle of the fuel canin direct contact with the flap of themisfuel prevention device and pour slowly.

The misfuel prevention device will beactivated the next time a standard nozzle is used.
This tool will become available durin
g the year.



Tr a v e l l i ng abroad
As Diesel fuel pump nozzles may be different in other countries, the presence of the misfuel prevention device maymake refuelling impossible.
Before travelling abroad, we recommend that you check with the CITROËN dealer network, whether your vehicle is suitablefor the fuel pumps in the country in which you want to travel.
