Compatibility of fuels
Petrol fuels conforming to the EN228 standard
containing up to 5% and 10% ethanol respectively.
Diesel fuels conforming to the EN590, EN16734
and EN16709 standards and containing up to
7%, 10%, 20% and 30% fatty acid methyl ester
respectively. The use of B20 or B30 fuels, even
occasionally, imposes special maintenance
conditions referred to as "Arduous conditions".
Paraffinic Diesel fuel conforming to the EN15940
standard.
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 system).
The only fuel additives authorised for use
are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
Diesel at low temperature
At temperatures below 0 °C (+32 °F), the
formation of paraffins in summer-type Diesel
fuels could prevent the engine from operating correctly. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50 % full.
At temperatures below -15 °C (+5 °F) to avoid
problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Certain fuels could damage your vehicle’s engine.
In certain countries, the use of a particular fuel
may be required (specific octane rating, specific
trade name, etc.) to ensure correct operation of
the engine.
For all additional information, consult a dealer.
Refuelling
Fuel tank capacity: approximately 44 litres
(petrol) or 41 litres (Diesel).
Reserve level: approximately 6 litres.
Low fuel level
When the low fuel level is reached, this
warning lamp comes on on the instrument
panel, accompanied by an onscreen message and
an audible signal. When it first comes on, about 6
litres of fuel remain in the tank.
Until sufficient fuel is added, this warning lamp
appears every time the ignition is switched on,
accompanied by an onscreen message and an
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.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
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:
► You must switch off the engine.
►With the vehicle unlocked, press the rear-
central part of the filler flap to open it.
