be repeated every time the ignition is switched
on, with increasing frequency as the fuel level
decreases and approaches zero.
Refuel without delay to avoid running out of fuel.
Never drive until completely empty, as this
could damage the fuel pump, the emissions
control and injection systems.

Practical information
7Refuelling
Fuel tank capacity: 30 litres.
Reserve level: approximately 5 litres.
Low fuel level
When the low fuel level is reached, this
warning lamp comes on on the instrument
panel, accompanied by an audible signal. When
it first comes on, about 5 litres of fuel remain.
Until sufficient fuel is added, this warning lamp
appears every time the ignition is switched on,
accompanied by an audible signal. When driving,
the 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.
Refuelling
Additions of fuel 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 entirely
normal, resulting from the sealing of the fuel
system.
To refuel in complete safety:
►

Y
ou must switch off the engine.


► Lift the fuel filler flap lever , located on the
floor beside the driver's seat, to open the flap.
►

T
ake care to select the pump that delivers the
correct fuel type for the vehicle's engine (see a
reminder label on the inside of the filler flap).


► Turn the filler cap to the left and remove it.
► Introduce the filler nozzle and push it in as
far as possible before starting to refuel (risk of
blowback).
►

Fill the tank.
Do not continue past the first cut-off of the
nozzle, as this may cause malfunctions.
► Refit the filler cap.
► T urn it to the right.
►

Push the filler flap to close it.
If you have put in wrong/dirty/
contaminated fuel or H2O mixed fuel in
the vehicle, you must have the fuel tank
drained and filled with the correct fuel before
starting the engine.
Contact a CITROËN dealer for the fuel
system cleaning.
The vehicle is fitted with a catalytic converter, a
device which helps to reduce the level of harmful
emissions in the exhaust gases.
You must use unleaded fuel.
The filler neck is narrower, admitting unleaded
petrol nozzles only.
Fuel cut-off
Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of a
collision.
Bonnet
When the engine is hot, handle the
exterior safety catch and the bonnet stay
with care (risk of burns), using the protected
area.
When the bonnet is open, take care not to
damage the safety catch.
