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.

In order not to overfill the AdBlue® tank:
– Add between 10 and 13 litres using AdBlue® containers.
– Stop after the nozzle’ s first automatic cut-out, if you are refilling at a service station.
The system only registers AdBlue® top-ups of 5 litres or more.
If the AdBlue® tank is completely empty
– which is confirmed by the message
"Top up AdBlue: Starting impossible" – it is essential to add at least 5 litres.
After refilling
► Perform the same sequence of operations in reverse order.
Do not dispose of AdBlue® containers in
the household waste.
Place them in a container reserved for this
purpose or take them back to where you
purchased them.
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).

In the event of a breakdown
8Running out of fuel
(Diesel)
With Diesel engines, the fuel system must be
primed if you run out of fuel.
Before starting to prime the system, it is
essential to put at least 5 litres of Diesel into the
fuel tank.
For more information on Refuelling and
on Misfuel prevention (Diesel), please
refer to the corresponding section.
For non-BlueHDi versions, the fuel system
components are located in the engine
compartment, possibly under the removable
cover.
For more information on the Engine
compartment, in particular the location
of these components under the bonnet,
please refer to the corresponding section.
BlueHDi engines
► Switch on the ignition (without starting the engine).► Wait around 1 minute and switch off the ignition.► Operate the starter motor to start the engine.If the engine does not start at the first attempt,
do not keep trying, but restart the procedure.
Non-BlueHDi engines
► Open the bonnet and then, if necessary , unclip the cover to access the priming pump.► Operate the priming pump repeatedly until resistance is felt (resistance may be
felt at the first press).
► Operate the starter motor to start the engine (if the engine does not start at the first attempt,
wait around 15 seconds before trying again).
► If the engine does not start after a few attempts, operate the priming pump again, then
the starter motor.
► Put the cover back in place and clip it in, then close the bonnet.
Tool kit

Bluetooth® audio system
Bluetooth® audio system

The different functions and settings described vary according to the version
and configuration of your vehicle.
As a safety measure and because it requires sustained attention by the driver,
the pairing of a Bluetooth mobile telephone
with the Bluetooth hands-free system of your
audio system must be done with the vehicle
stationary and the ignition on.
Your audio system is coded in such a way that it will only operate in your
vehicle.
All work on the system must be carried out
exclusively by a dealer or qualified workshop,
to avoid any risk of electrocution, fire or
mechanical faults.
To avoid discharging the battery, the audio system may switch off after a few
minutes if the engine is not running.
