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 (depending on version):
approximately 47 or 50 litres (petrol) or
approximately 45 or 50 litres (Diesel).
Reserve level: approximately 5 litres.
Low fuel level
When the low fuel level is reached, this
warning lamp in the instrument panel
comes on, accompanied by an audible warning,
a message and the last bar of the fuel gauge
flashes in red.
When it first comes on, about 5 litres of fuel
remain in the tank.
This warning lamp will come on every time
the ignition is switched on, accompanied by a
message and an audible signal, until a sufficient
addition of fuel is made. This audible signal and
message are repeated with increasing frequency
as the fuel level drops and approaches " 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:
►

Y
ou must switch off the engine.

correct fuel type for the vehicle's engine (see a
reminder label on the inside of the filler flap).
►

Insert the key in the filler cap then turn it to
the left, or turn the filler cap manually to the left
(depending on version).


► Remove the filler cap and hang it on its
carrier (on the filler flap).
►

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

urn the key to the right then remove it from
the filler cap, or turn the filler cap manually to the
right (depending on version).
►

Push the filler flap to close it.
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 vehicle is fitted with a catalytic converter, a
device 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, admitting unleaded
petrol nozzles only.
Fuel cut-off
Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of a
collision.
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 inserted 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.
It remains possible to use a fuel jerrycan
to fill the 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.
Before travelling abroad, it is advisable to
check with a CITROËN dealer if the vehicle is
suitable for the distribution equipment of the
countries visited.

Practical information
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
► Grasp the dipstick by its coloured grip and
pull it out completely.
► Wipe the end of the dipstick using a clean,
lint-free cloth.


► Unclip the stay from its housing and place it
in the support slot to hold the bonnet open.
Closing
► Hold the bonnet and pull out the stay from the
support slot.
►

Clip the stay in its housing.
►


Lower the bonnet and release it near the end
of its travel.
►


Pull on the bonnet to check that it is locked
correctly

.
Because of the presence of electrical
equipment under the bonnet, it is strongly
recommended that exposure to water (rain,
washing, etc.) be limited.

Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop.
The fluids must comply with the manufacturer's requirements and with
the vehicle's engine.
Take care when working under the bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and the
cooling fan could start at any time (even with
the ignition off).

Practical information
city driving), change it twice as often, if
necessary.
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
The start of saturation of the particle filter
is signalled by the temporary illumination
of this warning lamp, accompanied by a
message warning of the risk of the filter clogging
up.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this
indicates a low Diesel additive level.
For more information on Checking levels,
refer to the corresponding section.
If the level is close to or below the " MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the
particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible warning and a message warning that the
additive level is too low.
Topping up
This additive must be topped up without delay by
a CITROËN dealer or a qualified workshop.
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the AdBlue range
indicators, refer to the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on the Supply of AdBlue,
refer to the corresponding section.
Checks

dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.

Practical information
Storage recommendations
AdBlue® freezes at about -11°C and deteriorates
above +25°C. Containers should be stored in a
cool area and protected from direct sunlight.
Under these conditions, the fluid can be kept for
at least a year.
If the fluid has frozen, it can be used once it has
completely thawed out in the ambient air.
Never store AdBlue® containers in your
vehicle.
Precautions for use
AdBlue® is a urea-based solution. This fluid is
non-flammable, colourless and odourless (when
kept in a cool place).
In the event of contact with the skin, wash the
affected area with soap and running water. In the
event of contact with the eyes, immediately rinse
the eyes with large amounts of water or with an
eye wash solution for at least 15 minutes. Seek
medical attention if you feel a persistent burning
sensation or irritation.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (high temperature, for
example), the risk of release of ammonia cannot
be excluded: do not inhale the fluid. Ammonia
vapours have an irritant effect on mucous
membranes (eyes, nose and throat).
Store AdBlue® out of the reach of
children, in its original container.
the vehicle's road holding - risk of an
accident! Driving 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.

Using different size wheels and tyres from those
specifi ed can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse e

ffect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
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 associates 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 5,600
miles (9,000 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 blocked.
If the estimated distance travelled by the vehicle
between two services is greater than 12,500
miles (20,000 km), it will be necessary to top up
the AdBlue.
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
system required by legislation prevents
starting of the engine.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard: the vehicle becomes
polluting.
In the event of a confirmed SCR system
malfunction, it is essential to visit a CITROËN
dealer or a qualified workshop. After 680
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.
For the correct operation of the SCR
system:
–
Use only AdBlue® fluid that meets the ISO
22241 standard.
–
Never transfer

AdBlue
® to another container
as it would lose its purity.
–
Never dilute AdBlue® with water.
It is possible to obtain AdBlue
® from a CITROËN
dealer or a qualified workshop.
You can also visit a service station equipped with AdBlue® pumps specially
designed for passenger vehicles.
Never top up from an AdBlue® dispenser
reserved for heavy goods vehicles.

Procedure
Before starting the top-up procedure, ensure that
the vehicle is parked on a flat and level surface.
In wintry conditions, ensure that the temperature
of the vehicle is above -11
°C. Otherwise, the
AdBlue
® may be frozen and therefore cannot
be poured into its tank. Park your vehicle in a
warmer area for a few hours to allow the top-up
to be carried out.
Never pour AdBlue® into the Diesel fuel
tank.
If any AdBlue® is splashed, or if there are
any spillages on the bodywork, rinse
immediately with cold water or wipe with a
damp cloth.
If the fluid has crystallised, clean it off using a
sponge and hot water.
Important: in the event of a top-up after
a breakdown because of a lack of
AdBlue, it is essential to wait around 5
minutes before switching on the ignition,
without opening the driver’s door,
unlocking the vehicle, introducing the key
into the ignition switch, or introducing the
key of the “Keyless Entry and Starting

”
system into the passenger compartment

.
Switch on the ignition, then wait for 10
seconds before starting the engine.
► Switch off the ignition and remove the key
from the switch to switch off the engine.
or
►

With Keyless Entry and Starting, press the
"

START/STOP" button to switch off the engine.
