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
passenger's floor (Minibus).
On other versions, the second button is
replaced by a fuse; contact a CITROËN
dealer or a qualified workshop.

BLuEHdI
A nd AdB L u E® AddItIVE
AdBlue® is the brand name of the solution
needed for operation of the SCR system.
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 objective of BlueHDi is to reduce by
up to 90% the emissions of NOx (nitrous
oxides) in the air, 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
®
fluid into the exhaust system. This operation can also be carried out
by a CITROËN dealer or a qualified
workshop.
Scr technology
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 botles 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
While the quantity of AdBlue® in the additive
tank
is sufficient, no information is displayed.
On the other hand, once the additive level
drops to the quantity needed for a range
of 1 500 miles (2 400 km) driving, you
are warned by different temporary signals
(warning lamp, message, audible signal).
As more miles are covered, these signals
intensify and the message becomes
permanent.
Filling the additive tank
For light vehicles, 5 or 10 litre containers
and 1.89 litre (1/2 US gallon) bottles are
available from CITROËN dealers.
If you want to fill the AdBlue
® tank yourself,
ensure that you have a suitable filler pipe,
which may or may not be supplied with the
additive container. When the AdBlue® tank is empty,
restarting becomes impossible.
It is strongly recommended that you do
not wait for the successive alerts before
topping-up the AdBlue
® tank, but do this as
soon as possible.

range indicators
Different levels of alert are triggered
according to the remaining driving range
threshold.
You will be informed as each mileage
threshold is reached and the alerts will
change from temporary to permanent.
-
The 1st alert is triggered at a remaining
driving range of 1 500 miles (2 400 km).
-

The 2nd alert is triggered at a remaining
driving range of 375 miles (600 km).
Up to 0 miles, at which point it will be
impossible to restart the engine after a stop.
r

(2 400 km)
No information displayed.
Once the 1 500 miles (2

400 km)
threshold is reached, this
warning
lamp comes on
temporarily and the remaining
range message is displayed.
Every time the ignition is switched on, the
alert is given, together with an audible
signal.
r

emaining range less than 1 500 miles
(2

400 km) and greater than 375 miles
(600 km) 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.
At 0 miles the system installed in the
vehicle to meet the emissions standard
will prevent engine starting. The 0 level of AdBlue
® additive has been
reached.
Your vehicle's exhaust emissions no longer
meet the "Euro 6" standard and the engine
will not start.
To be able to restart the vehicle, you must
add at least 3.8 litres of AdBlue
®.

Pour the additive into the tank (by the

filler with the blue cap).

Switch on the ignition without starting.

Avoid waiting until the remaining
range is 0 miles!
The alert is repeated when driving until the
AdBlue additive tank has been topped-up
with sufficient additive.
Unless the additive in the special additive
tank is topped-up, you risk immobilisation of
the vehicle. Following this, make a further fill to the
special additive tank, the capacity of
which is 15 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.
Starting prevented, having covered the
250 miles (400 km)
d

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.
Go to a CITROËN dealer or a qualified
workshop.

Obtain a bottle of

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 additive is split or splashed,
wash immediately with cold water or
wipe with a damp cloth.
If the additive has crystallised, clean it off
using a sponge and hot water.

refit the filler cap
-
Refit the blue cap to the tank and turn it

a 6
th of a turn clockwise, to its stop.
-

Close the filler flap.
Never dispose of

AdBlue

bottles in the household waste. Place
them in a special container provided this
purpose or take them to your dealer.
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 additive with water.
Never pour the additive into the Diesel fuel
tank.
recommendations on storage
Never store containers or bottles of
AdBlue® in your vehicle. Freezing of the AdBlue
® additive
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 additive can be
kept for at least a year.
Additive that has been frozen can be used
once it has thawed out in ambient air. 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 additive becomes a liquid again.
The emissions warning lamp does not go off
immediately, but does so after a few miles
of driving.
