Fuel used for petrol engines
The petrol engines are compatible with biofuels
that conform to current and future European
standards and which can be obtained from
filling stations:Petrol that meets standard EN228,
mixed with a biofuel that meets
standard EN15376.
The only petrol additives authorised for
use are those that meet the B715001
standard.
Fuel used for Diesel
engines
The Diesel engines are compatible with
biofuels that conform to current and future
European standards and which can be
obtained from filling stations: Diesel fuel that meets standard
EN16734
mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 10% Fatty Acid Methyl
Ester).
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 use of B20 or B30 fuel that meets
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".
For more information, 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, etc.) is strictly prohibited
(risk of damage to the engine and fuel
syste m). The only Diesel additives authorised for
use are those that meet the B715000
standard.
Diesel at low temperature
At temperatures below 0°C (+32°F), the
formation of paraffins in summer-type Diesel
fuels could entail an abnormal operation
of the fuel supply circuit. To avoid this, we
recommend using winter-type Diesel fuel and
keeping the fuel tank more than 50% full.
If, despite this, at temperatures below -15°C
(+5°F) the engine has problems starting,
just leave the vehicle in a garage or heated
workshop for a little while.
Travelling abroad
Cer tain fuels could damage the engine of
your vehicle.
In cer tain countries, the use of a par ticular
fuel may be required (specific octane
rating, specific trade name, etc.) to ensure
correct operation of the engine.
For any additional information, contact a dealer.
Compatibility of fuels
Diesel fuel that meets standard
EN590
mixed with a biofuel that meets
standard EN14214 (possibly containing
up to 7% Fatty Acid Methyl Ester).

Fuel tank
Tank capacity: approximately 45 litres.
I f you have put the wrong fuel in your
vehicle, you must have the fuel tank
drained and filled with the correct fuel
before star ting the engine.
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 a message.
When it first comes on, about 5


litres of fuel
remain in the tank.
This warning lamp will come on every time
the ignition is switched on, accompanied
by a message and an audible signal, until
a sufficient addition of fuel is made. This
audible signal and message are repeated with
increasing frequency as the fuel level drops
and approaches " 0".
Refuel as soon as possible to avoid running
out.
For more information on Running out of
fuel (Diesel) , refer to the corresponding
section.
Refilling
A self-adhesive label on the inner face of the
filler flap reminds you of the type of fuel to use,
depending on your engine.
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:
F

Y
ou must switch off the engine.
F

Fuel cut- of f
Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of a
collision.
Misfuel prevention
(Diesel)
(Depending on country of sale)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol. It helps
avoid the risk of engine damage that can result
from filling with the wrong fuel.
Operation
When a petrol filler nozzle is introduced into the
Diesel tank, it comes into contact with the flap.
The system remains closed and prevents filling.It remains possible to use a fuel can to fill
the tank.
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.
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.
Do not persist but introduce a Diesel type
filler nozzle.
Snow chains
In wintry conditions, snow chains
improve traction as well as the
behaviour of the vehicle when
braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Take account of the legislation in force in
your country on the use of snow chains
and the maximum authorised speed.
Installation tips
F If you have to fit the chains during a journey, stop the vehicle on a flat sur face on the side
of the road.
F
