Practical information
7Compatibility 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 45 litres.
Reserve level: approximately 5 litres.
Low fuel level
/2
1 1When the low fuel level is reached, one of these warning lamps comes
on on the instrument panel, accompanied by an
onscreen message and 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 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.

RDS
The external environment (hills, buildings, tunnels, basement car parks,
etc.) may block reception, including in RDS
mode. This is a normal effect of the way in
which radio waves are transmitted and does
not indicate any failure of the audio
equipment.
If RDS is not available, the RDS symbol
appears struck out in the screen.
The RDS, if activated, enables you to continue listening to the same station by
automatic retuning to alternative frequencies.
However, in certain conditions, coverage of
an RDS station may not be assured
throughout the entire country as radio stations
do not cover 100% of the territory. This
explains the loss of reception of the station
during a journey.

or deactivate RDS directly.
Long procedure
Press the MENU button.
Select "Audio functions ".
Press OK.
Select the "FM waveband preferences"

the current audio source (Radio, CD, etc.) is
interrupted automatically to play the TA
message. Normal play of the media
previously playing is resumed at the end of
the message.

interrupted automatically to receive the INFO
message. Normal play of the media
previously playing is resumed at the end of
the message.
