Fuel Tank; Low Fuel Level; Refuelling; Misfuel Prevention (Diesel) - CITROEN C5 AIRCROSS Handbook

Practical information

Fuel tank

Capacity of the tank: Approximately
53 litres.

Low fuel level

When the level in the tank becomes
low, this warning lamp comes on in
the instrument panel, accompanied
by the display of a message and an
1
audible signal. When it first comes
1 /2
on, there remains about 6 litres of
fuel in the tank.
Until sufficient fuel is added, this warning lamp
reappears 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.

Refuelling

Fuel top-ups must be of at least 5 litres 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
180
entirely normal and results from the sealing of
the fuel system.
To refuel in complete safety:
F You must switch off the engine.
F With the vehicle unlocked, press the rear-
central part of the filler flap to open it.
F 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).
F Turn the filler cap to the left.
F Remove the filler cap and hang it on its
carrier (on the filler flap).
F Introduce the filler nozzle and push it in as
far as possible before starting to refuel (risk
of blowback).
F Fill the tank. Do not continue past the
third cut-off of the nozzle, as this may
cause malfunctions.
F Refit the filler cap.
F Turn it to the right.
F Push the filler flap to close it.
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, you must use unleaded
fuel.
The filler neck is narrower, admitting unleaded
petrol nozzles only.
If your vehicle is fitted with Stop & Start,
never refuel with the engine in STOP
mode; you must switch off the ignition.
