Practical information  
correctly. In these temperature conditions, use  
winter-type Diesel fuel and keep the fuel tank  
more than 50 % full.  
signal are repeated with increasing frequency as  
the fuel level drops towards 0.  
Compatibility of fuels  
You must refuel as soon as possible to avoid  
running out of fuel.  
At temperatures below -15 °C (+5 °F) to avoid  
problems starting, it is best to park the vehicle  
under shelter (heated garage).  
Petrol fuels conforming to the EN228 standard  
containing up to 5% and 10% ethanol respectively.  
For more information on Running out of fuel  
(Diesel), refer to the corresponding section.  
A small arrow by the warning lamp  
indicates which side of the vehicle the  
fuel filler flap is located on.  
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.  
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".  
Stop & Start  
Never refuel with the engine in STOP  
mode; you must switch off the ignition.  
For all additional information, consult a dealer.  
Refuelling  
Any addition of fuel must be in quantities of at  
least 10 litres, in order to be registered by the fuel  
gauge.  
Refuelling  
Fuel tank capacity: approximately 55  
litres (Diesel), 62 litres (Petrol) or 43 litres  
(Rechargeable hybrid).  
Paraffinic Diesel fuel conforming to the EN15940  
standard.  
The use of any other type of (bio)fuel  
(e.g. pure or diluted vegetable or animal  
oils, domestic fuel) is strictly prohibited - risk  
of damaging the engine and fuel system!  
Opening the filler flap 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:  
Reserve level: approximately 6 litres.  
Low fuel level  
When the low fuel level is reached, this  
warning lamp lights up on the instrument  
panel, accompanied by the display of a message  
and an audible signal. When it first comes on,  
about 6 litres of fuel remain.  
►ꢀ Always switch off the engine.  
The only fuel additives authorised for use  
are those that meet the B715001 (petrol)  
or B715000 (Diesel) standards.  
Until sufficient fuel is added, this warning lamp  
appears every time the ignition is switched on,  
accompanied by the message and the audible  
signal. When driving, this message and audible  
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

Practical information  
►ꢀ To open the filler flap, press the flap opening  
button for more than 2 seconds or, with the  
vehicle unlocked, press the rear of the filler flap  
(depending on version).

If the filler flap is accidentally closed  
before refuelling, it cannot be opened  
manually. Restart the engine and move the  
vehicle a few metres before pressing the  
filler flap opening button again.  
Rechargeable hybrid vehicles  
After pressing the button on the  
dashboard, the filler flap may not open for  
several minutes. A sound is emitted when the  
filler flap opens.  
Misfuel prevention (Diesel)  
(Depending on country of sale.)  
If the flap becomes stuck, press and hold  
the button on the dashboard for more than  
3 seconds.  
This mechanical device prevents filling the tank of  
a Diesel vehicle with petrol.  
Located in the filler neck, the misfuel prevention  
device is visible when the filler cap is removed.  
►ꢀ Insert the filler nozzle and push it in as far as  
possible before starting to refuel (to minimise the  
risk of splashing).  
Operation  
►ꢀ Fill the tank.  
Do not continue after the nozzle’s third cut-out.  
Doing so may cause malfunctions.  
►ꢀ Push the fuel filler flap to close it.  
The vehicle is fitted with a catalytic converter,  
which helps to reduce the level of harmful  
emissions in the exhaust gases.  
The filler cap is built into the flap.  
►ꢀ Select a pump that delivers the correct fuel  
type for the vehicle's engine (see a reminder label  
on the inside of the filler flap).  
When a petrol filler nozzle is introduced into the  
fuel filler neck of a Diesel vehicle, it comes into  
contact with the flap. The system remains closed  
and prevents filling.  
For petrol engines, you must use unleaded fuel.  
The filler neck is narrower, allowing only unleaded  
petrol nozzles to be inserted.  
Do not persist but introduce a Diesel type filler  
nozzle.  
If you have put in the wrong fuel for the  
vehicle, you must have the fuel tank  
drained and filled with the correct fuel before  
starting the engine.  
The misfuel prevention device does not  
prevent filling with a jerrycan, regardless  
of the fuel type.
