Fuel tank
Capacity of the tank: Approximately
53
litres.
Low fuel level
When the level in the tank becomes
low, this warning lamp comes on in
the instrument panel, accompanied
by the display of a
message and an
audible signal. When it first comes
on, there remains about 6


litres of
fuel in the tank.
Refuelling
Fuel top-ups must be of at least 5 litres in order
t o be registered by the fuel gauge.

For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, admitting unleaded
petrol nozzles only.
If your vehicle is fitted with Stop & Start,
never refuel with the engine in STOP
mode; you must switch off the ignition.
Misfuel prevention (Diesel)
(Depending on country of sale.)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol.
Operation
Until sufficient fuel is added, this warning lamp
reappears 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. entirely normal and results from the sealing of
the fuel system.
Practical information

181
It remains possible to use a fuel can to fill
t he tank.
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 a
CITROËN dealer whether your
vehicle is suitable for the fuel pumps in the
country in which you intend to travel.
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.
Compatibility of fuels
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 fuel additives authorised for use
are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
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 respectively
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.
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
Cer tain fuels could damage your vehicle's
engine.
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 all additional information, consult a


dealer.

Towing device
Load distribution
F Distribute the load in the trailer so that the
heaviest items are as close as possible to
the axle and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10% for every
1,000
metres of altitude. Use towing devices and their genuine
harnesses approved by CITROËN. It
is recommended that the installation
be per formed by a
CITROËN dealer or
a

qualified workshop.
If the towing device is not fitted by
a CITROËN dealer, it must still be
fitted in accordance with the vehicle
manufacturer's instructions.
Important: for versions equipped with
the motorised tailgate with Hands-Free
Tailgate Access function, if a
towing
device other than a
genuine CITROËN
one is installed, it is essential to visit
a
CITROËN dealer or a qualified
workshop to recalibrate the detection
system: risk of "Hands-Free Tailgate
Access" function failure.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing system is used.
