Practical information
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 53 litres
(Petrol or Diesel) or 43 litres (Rechargeable
hybrid).
Reserve level: approximately 6 litres.
Low fuel level
/2
1 1When 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 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.
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.
The filler cap is built into the filler
flap or must be
unscrewed (depending on version).
To refuel in complete safety:
►

Y
ou must switch off the engine.

Practical information
7Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is essential to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road-holding and braking performance.
For your safety and driving comfort, it is
important to have them regularly checked by a
CITROËN dealer or a qualified workshop.
Timing and accessory kits
Timing and accessory kits are used from
the time the engine is started until it is
switched off. It is normal for them to wear over
time.
A
faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
AdBlue® (BlueHDi)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles with
a system that combines SCR (Selective Catalytic
Reduction) with a Diesel Particle Filter (DPF) for
the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue® is contained in a special
tank holding about 17 litres.
Its capacity allows a driving range of
approximately 4,000
miles (6,500 km),
which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
further 1,500 miles (2,400

km) before the tank is
empty and the vehicle is immobilised.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators, please refer to the
corresponding sections.
Once the AdBlue® tank is empty, a device
required by law prevents the engine from
being restarted.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard and the vehicle starts
polluting the environment.
In the event of a confirmed SCR system
malfunction, it is essential to visit a CITROËN
dealer or a qualified workshop. After 685
miles (1,100 km), a device is automatically
activated to prevent the engine from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is stopped.
Freezing of the AdBlue®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater for the
AdBlue
® tank, allowing you to continue driving
in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reserve level has been reached.
