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.

– 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
8At the battery, it is only necessary to disconnect
the (+) terminal.
Quick-release terminal clamp
Disconnecting the (+) terminal

► Raise the lever A fully to release the clamp
B.
► Remove the clamp B by lifting it off.
Reconnecting the (+) terminal


► Raise the lever A fully.► Refit the open clamp B on the (+) terminal.► Push the clamp B fully down.► Lower the lever A to lock the clamp B.
Do not force the lever as locking will not
be possible if the clamp is not positioned
correctly; start the procedure again.
Following reconnection of the battery
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, in order to enable the electronic systems
to initialise.
For right-hand drive vehicles, when the
total distance recorder has reached 37
miles (60 km), it is necessary to wait approx.
15 minutes before starting the engine.
However, if minor problems persist following
this operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the corresponding section, you must
yourself reinitialise or reset certain systems,
such as:
– the key with remote control or electronic key (depending on version),– the sunroof and its electric blind,– the electric windows,– the date and time,– the preset radio stations.
The Stop & Start system may not be
operational during the trip following the
first engine start.
In this case, the system will only be
available again after a continuous period of
immobilisation of the vehicle, a period which
depends on the exterior temperature and the
state of charge of the battery (up to about 8
hours).

The following information groups together the answers to the most frequently asked questions
concerning your audio system. With the engine off, the audio system
switches off after a few minutes of use.
When the engine is switched off, the audio
system operating time depends on the state of
charge of the battery.
The switch-off is normal: the audio system
switches to economy mode and switches off to
avoid discharging the vehicle's battery.
► Start the vehicle’
s engine to increase the charge of the battery.
The message "the audio system is
overheated" is displayed onscreen.
To protect the installation if the ambient
