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 (e.g. pure or diluted vegetable or animal
oils, domestic fuel) is strictly prohibited - risk
of damaging 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 52 litres
(Petrol or Diesel) or 40 litres (Rechargeable
hybrid).
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.
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
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.
A small arrow by the warning lamp indicates which side of the vehicle the
fuel filler flap is located on.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Refuelling
Any addition of fuel must be in quantities of at
least 10 litres, in order to be registered by the
fuel gauge.
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:
►

Always switch off the engine.

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).
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.
If the flap becomes stuck, press and hold
the button on the dashboard for more than
3

seconds.
►

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).


► Turn the filler cap to the left, remove it
and place it on its support on the filler flap
(depending on version).
►

Insert the filler nozzle and push it in as far as
possible before starting to refuel (to minimise the
risk of splashing).
►


Fill the tank.
Do not continue after the nozzle’

s third cut-
out. Doing so may cause malfunctions.
► Put the filler cap back in place and turn it to
the right (depending on version).
►

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.
For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, allowing only
unleaded petrol nozzles to be inserted.
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.
Misfuel prevention (Diesel)
(Depending on country of sale.)
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.
Operation

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.
Do not persist but introduce a Diesel type
filler nozzle.
The misfuel prevention device does not prevent filling with a jerrycan, regardless
of the fuel type.
Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Before travelling abroad, it is advisable to
check with a PEUGEOT dealer if the vehicle
is suitable for the distribution equipment of the
countries visited. CarM an uals 2 .c o m

restart if the traction battery charge level
is a low or very low, especially at negative
ambient temperatures. ALWAYS make sure
that the traction battery has a charge between
20% and 40% if you do not plan to use your
vehicle for several weeks.
Do not connect the charging cable.
Always park the vehicle in a place with
temperatures between -10°C and 30°C
(parking in a place with extreme temperatures
can damage the traction battery).
Refer to the Accessory battery
(Rechargeable hybrid) section for the
battery disconnection procedure.
Precautions
Rechargeable hybrid vehicles have
been developed in accordance with the
recommendations for maximum electromagnetic
field limits established by the ICNIRP
(International Commission on Non-Ionizing
Radiation Protection - 1998 Guidelines).
Wearers of pacemakers or equivalent
devices should consult a doctor to
enquire about any applicable precautionary
measures, or contact the manufacturer of their
implanted electronic medical device to check that
it is guaranteed to operate in an environment
compliant with the ICNIRP guidelines.

maximum permitted without exceeding it.
Air density decreases with altitude, thus reducing
engine performance.
The maximum towable load
must be reduced by 10% per 1,000
metres of
altitude.
Use genuine towing devices and wiring
harnesses approved by PEUGEOT. We
recommend having them fitted by a
PEUGEOT dealer or a qualified workshop.
If not fitted by a PEUGEOT dealer, they must
still be fitted in accordance with the vehicle
manufacturer's instructions.
Important: if the vehicle has a motorised
tailgate and Hands-Free Tailgate Access
function, and a towing device has been fitted
outside the PEUGEOT dealer network, it
is essential to visit a PEUGEOT dealer or
a qualified workshop to have the detection
system recalibrated
- risk of malfunction of the
Hands-Free Tailgate Access function.
Certain driving or manoeuvring aid functions
are automatically deactivated while an
approved towing system is in use.
For more information about driving with a
towing device fitted to a trailer and associated
with the Trailer stability assist, refer to the
corresponding section.
Comply with the maximum authorised
towable weight, as indicated on your
vehicle's registration certificate, on the
manufacturer's label and in the Technical
data section of this guide.
If using accessories attached to the
towing device (e.g. bicycle carriers, tow
boxes):
