FuEL SYS t EM cut- OFF
After the collision and before restore
these supplies, check that there is no
fuel leak or sparks, to avoid the risk of fire. In the event of a collision, a device
automatically cuts off the fuel supply
from the engine and cuts off the vehicle's
electrical supply
It triggers operation of the hazard warning
lamps and courtesy lamps, and unlocking of
the doors. To restore the fuel supply, press the first
button, located below the steering wheel.
Then to restore the electrical power
supply, press the second button, located
in the battery compartment under the front

BLuEHdI And AdBLuE®
AdBlue® is the brand name of the solution
needed for operation of the SCR system.
This solution is a urea-based fluid.
This fluid is non-flammable, colourless and
odourless. BlueHDI vehicles have a specific AdBlue
®
additive tank with a capacity of 15 litres.
It has an exterior filler located behind the
fuel filler flap below the fuel filler cap and
closed with a blue filler cap.
The aim of BlueHDi is to reduce the
emissions of NOx (nitrous oxides) in the
air by up to 90%, using a system that
converts NOx into water vapour and nitrogen
in a dedicated catalytic converter: SCR
(Selective Catalytic Reduction).
This objective meets the "Euro 6" emissions
standard adopted by the European Union
aimed at limiting the emissions of pollutants
from internal combustion engines.
The SCR technology used on BlueHDi
engines involves the injection of AdBlue®
into the exhaust system.

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.

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:
-

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.

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.

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.

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.
