Electronic stability control
(ESC)
The electronic stability control programme includes the following systems:
– Anti-lock braking system (ABS) and Electronic brake force distribution (EBFD).– Emergency braking assistance (EBA).– Anti-slip regulation (ASR).– Dynamic stability control (DSC).
Anti-lock braking system
(ABS) and Electronic brake
force distribution (EBFD)
These systems enhance the vehicle’s stability
and handling during braking, and enable greater
control while cornering, particularly on poor or
slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
EBFD manages the braking pressure wheel by
wheel.
This warning lamp comes on fixed in the event of an ABS malfunction.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Contact a CITROËN dealer or a qualified

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.

Practical information
7Engine coolant
It is normal to top up this fluid between two services.
The check and top-up must only be done with
the engine cold.
A low level presents a risk of serious damage to
the engine.
The level of this fluid should be close to the
"MAX" mark but should never exceed it.
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.
Cooling of the engine when stopped
The engine cooling fan may start after
the engine has been switched off.
Take care with objects or clothing that
could be caught in the blades of the fan!
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
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
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
7Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50 km/h), add 0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on 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.
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 imperative 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.
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.

136
Practical information
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.
Recommendations on storage
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 at room temperature.
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.
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.

► With the vehicle unlocked and the fuel filler flap open, turn the blue cap of the AdBlue® tank
a quarter turn anti-clockwise.
Filling up
► With a container of AdBlue®: after checking
the expiry date, read the instructions on the
label carefully before pouring the contents of the
container into the vehicle's AdBlue tank.► With an AdBlue® pump: introduce the nozzle
and fill the tank until the nozzle automatically
cuts out.
In order not to overfill the AdBlue® tank:
– Add between 10 and 13 litres using AdBlue® containers.

Advice on care and
maintenance
General recommendations
Observe the following recommendations to avoid
damaging your vehicle.
Exterior
Never use a high-pressure jet wash in
the engine compartment, due to the risk
of damaging electrical components.
Do not wash the vehicle in strong sunshine or
extremely cold conditions.
When washing the vehicle at an
automatic roller-brush car wash, be sure
to lock the doors and, depending on version,
remove the electronic key and deactivate the
“hands-free” function (“Hands-Free Tailgate
Access”).
When using a pressure washer, hold the
lance at least 30 cm from the vehicle
(particularly when cleaning areas containing
chipped paint, sensors or seals).
Promptly clean up any stains containing
chemicals liable to damage the vehicle's paint
(including tree resin, bird droppings, insect
secretions, pollen and tar).
If justified by the environment, clean the
vehicle more frequently to remove salty
deposits (in coastal areas), soot (in industrial
estates) and mud (in wet or cold areas).
These substances can be highly corrosive.
Contact a CITROËN dealer or a qualified
workshop if you require advice on removing
stubborn stains requiring special products
(such as tar or insect removers).
