This operation can also be carried out
by a CITROËN dealer or a qualified
workshop.
These bottles and containers are available
from CITROËN dealers. Filling the AdBlue tank
Filling of the AdBlue
® tank can be done
using:
-

5 or 10 litres containers equipped with a

10 centimetre filler tube or the filling kit
available from CITROËN dealers,
-

1.89 litre bottles that are screwed onto

the filler neck, available from CITROËN
dealers,
-

or when at a fuel filling station equipped

with a special AdBlue
® delivery pump for
heavy or light vehicles. Good practice
Once the AdBlue level drops to the reserve
level, you are warned by different temporary
signals (warning lamp, message, audible
signal).
When the AdBlue
® tank is empty,
restarting becomes impossible.
It is strongly recommended that you do not
wait for the successive alerts, but top-up the
AdBlue
® as soon as possible.
To facilitate filling, an adaptor is also
available from CITROËN dealers.

Once the 350 miles (600 km) threshold
is reached, this warning lamp flashes,
accompanied by a message on the
remaining driving range.
The alert is repeated with an update of the
remaining driving range in steps of 30 miles
(50 km) travelled.
Every time the ignition is switched on, the alert is
given together with an audible signal.0 miles operating range reached: the system
installed in the vehicle to meet the emissions
standard will prevent engine starting.
Your vehicle's exhaust emissions no longer
meet the "Euro 6" standard and the engine will
not start.
Unless the AdBlue
® is topped-up in the
special additive tank, the vehicle will remain
immobilised.
To be able to restart the vehicle, you must:
-

top-up the
AdBlue® with at least
3.8 litres.
-

or

go to a CITROËN dealer or a qualified
workshop.

Fault with the Scr system
The diagnostic warning lamp
comes on.
Every time the ignition is
switched on, the emissions fault
is confirmed by an audible signal and a
message.
If it is a temporary fault, the alert disappears
as soon as the exhaust emissions return to
the levels required by the standard. Fault confirmed
In addition to the previous signals, the
remaining range allowed will be displayed in
miles (kilometres) in the instrument panel.
The alert will be repeated every 30 seconds
with an update of the driving range.
Go to a CITROËN dealer or a qualified
workshop as soon as possible.
You risk not being able to start the engine.

etection
At each attempt at starting,
the alert is activated and the
message on starting prevention is
displayed.
On the other hand, if the warning lamp


is still on after 30 miles (50 km) of
driving, the fault is confirmed.
An engine start prevention system
will be activated automatically after
250

miles (400 km) travelled following this
confirmation.

Obtain a bottle of
AdBlue
®. After first
checking the use-by date, read carefully
the instructions on use on the label
before pouring the contents of the bottle
into your vehicle's AdBlue
® tank.
Important: if your vehicle's
AdBlue
® tank is completely empty -
which is confirmed by the alert messages
and the impossibility of starting the engine,
you must add at least 3.8 litres
(so two 1.89 litre bottles).
-

After emptying the bottle, wipe away any

spillage around the tank filler using a
damp cloth.
If any fluid is split or splashed, wash


immediately with cold water or wipe
with a damp cloth.
If the fluid has crystallised, clean it off using
a sponge and hot water.
Use only AdBlue
® that meets

the ISO 22241 standard.
Please check the use-by date.
Read the instructions on the label.
Ensure that you have a suitable filler pipe,

Keep AdBlue
® out of the reach of
children, in its original container.
Never transfer AdBlue
® to another container:
it would loose its purity.
Never dilute the fluid with water.
Never pour the fluid into the Diesel fuel tank.
recommendations on storage
Never store containers or bottles of
AdBlue® in your vehicle.
Freezing of the AdBlue
®
The SCR system includes an AdBlue®
tank heater that ensures operation of
the vehicle in normal conditions.
In exceptional situations, such as when the
vehicle is kept at temperatures below -15°C
(5°F) for a long period, there may be an
emission fault alert related to freezing of the
AdBlue
® additive.
Park the vehicle in an area at a more
moderate temperature for a few hours until
the AdBlue
® becomes a fluid again.
The emissions warning lamp does not go off
immediately, but does so after a few miles
of driving.
Never dispose of AdBlue® fluid bottles
in the household waste.
Place them in a special container provided
this purpose or take them to your dealer.
AdBlue® freezes at about -11°C
(12.2° F) and deteriorates above 25°C
(77°F).
It is recommended that containers and
bottles be stored in a cool area and
protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a year.
Additive that has been frozen can be used
once it has thawed out in ambient air.

Access to the battery
Unscrew the 6 access cover retaining
screws.
Lift off or remove completely the access
cover.
Press lever 1 downwards to spread the
clamp.
Remove the terminal 2 from the negative (-)
post. The batteries contain harmful
substances such as sulphuric acid and
lead. They must be discarded in accordance
with the provisions of the law and must not,
in any circumstances, be discarded with
household waste.
Take used batteries to a special collection
point.
The charging operation must be carried
out in a ventilated area away from
naked flames or any possible sources of
sparks to eliminate the risk of explosion
and

fire.
Do not attempt to charge a frozen battery: it
must first be thawed to eliminate the risks of
explosion. If the battery has frozen, before
charging it have it checked by a specialist
who will check that the internal components
have not been damaged and that the
container is not cracked, which could mean
that there is a risk of a leak of toxic and
corrosive acid.
Proceed with a slow charge charge at low
current for a maximum pf about 24 hours to
avoid damaging the battery. Before disconnecting the battery, you must
wait for 2 minutes after switching off the
ignition.
Never disconnect a terminal when the
engine is running.
Never charge a battery without first
disconnecting the terminals.
Close the windows and doors before
disconnecting the battery.
After every reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to allow the electronic
systems to be initialised. If slight difficulties
are experienced after this, please contact a
CITROËN dealer or a qualified workshop.

The presence of this label, in particular
with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification;
the involvement of a CITROËN dealer or
a qualified workshop is essential when
replacing or disconnecting the battery.
After refitting the battery by a
CITROËN dealer or a qualified
workshop, the Stop & Start system will
only be active after a continuous period of
immobilisation of the vehicle, a period which
depends on the climatic conditions and the
state of charge of the battery (up to about
8 hours).
It is advisable to disconnect the
negative (-) terminal of the battery
if the vehicle is not to be used for a
period of more than one month.
The description of the battery charging
procedure is given as an indication only.
If the battery has been disconnected
for some time, it may be necessary to
reinitialise the following functions:
-

the display parameters (date,


time, language, distance unit and
temperature

unit),
-

the radio stations,
-


the central locking.
Some settings are cleared and must be


reprogrammed, consult a CITROËN.
If your vehicle is fitted with a tachograph or
an alarm, disconnection of the negative (-)
terminal of the battery (located under the
floor on the left-hand side, in the cab) is
recommended if the vehicle is not to be used
for a period of more than 5 days.
