AdBlue® additive and SCR system
for BlueHDi Diesel engines
To assure respect for the environment and
conformity with the new Euro 6 emissions
standard, without adversely affecting the
per formance or fuel consumption of Diesel
engines, CITROËN has taken the decision to
equip its vehicles with an effective system that
associates SCR (Selective Catalytic Reduction)
with a particle filter (FAP) for the treatment of
exhaust gases.
SCR system
Using a fluid called AdBlue® containing
urea, a

catalytic converter turns up to 85%
of nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment. The AdBlue
® is held in a special tank with a
capacity of about 17 litres: this provides a driving
range of about 12 500 miles (20 000 km). An
alert is triggered automatically to warn you when
the reserve level is reached: you can then drive
about 1 500 miles (2 400 km) before the tank is
e m pt y.
During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue
® tank is refilled in order to allow
normal operation of the SCR system.
If the estimated mileage of your vehicle
between two services is greater than
12 500 miles (20 000 km), it will be necessary
to top-up the AdBlue
®. Once the AdBlue
® tank is empty, a
s
ystem required by regulations prevents
starting of the engine.
If the SCR

system is faulty, the level
of emissions from your vehicle will no
longer meet the Euro 6 standard: your
vehicle becomes polluting.
In the event of a confirmed fault
with the SCR system, you must go
to a CITROËN dealer or a qualified
workshop as soon as possible: after
a running distance of 650 miles
(1

100 km), a system will be triggered
automatically to prevent engine starting.
In either case, a range indicator gives
you the distance you can travel before
the vehicle is immobilised.

Practical information

280
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 all weather
conditions.
Topping-up the AdBlue®
Filling the AdBlue® tank is an operation
included in every routine service on your
vehicle by a CITROËN dealer or a qualified
workshop.
Nevertheless, given the capacity of the tank, it
may be necessary to top-up the fluid between
services, more particularly if an alert (warning
lamps and a message) signals the requirement.
You can go to a CITROËN dealer or a qualified
workshop.
If you envisage topping-up yourself, please
read the following warnings carefully.Precautions in use
Use only AdBlue® fluid that meets the
ISO

22241 standard.
AdBlue® is a urea-based solution. This liquid is
non-flammable, colourless and odourless (kept
in a cool area).
In the event of contact with the skin, wash
the affected area with soap and water. In the
event of contact with the eyes, wash (irrigate)
the eyes with large amounts of water or with
an eye wash solution for at least 15 minutes.
If a burning sensation or irritation persists, get
medical attention.
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 vapour has an irritant effect on
mucous membranes (eyes, nose and throat). The supply in a non-drip container or bottle
simplifies topping-up. You can obtain 1.89 litre
(half a US gallon) bottles or 5 litre containers
from a CITROËN
dealer or a qualified
workshop. Never dilute AdBlue
® with water.
Never pour AdBlue® into the Diesel fuel
tank.
Never top-up from an AdBlue
®
dispenser reserved for heavy goods
vehicles.
Keep AdBlue
® out of the reach of
children, in its original container or
bottle.
Never transfer AdBlue
® to another
container: it would lose its purity.
Practical information

317
Never try to charge a frozen battery.
If the battery has been frozen, have
it checked by a CITROËN dealer or a
qualified workshop, who will check that
the internal components have not been
damaged and the casing is not cracked,
which could cause a leak of toxic and
corrosive acid.

F

A

t the end of the charging operation, switch
off the charger B before disconnecting the
cables from the battery A .
It is not necessary to disconnect the
battery.
If you envisage charging your vehicle's
battery yourself, use only a charger
compatible with lead-acid batteries of a
nominal voltage of 12 V. Follow the instructions for use provided
by the manufacturer of the charger.
Never reverse polarities.
Charging the battery using a battery charger
If this label is present, it is essential
to use only a 12 V charger, to avoid
causing irreversible damage to the
electrical components related to the
Stop & Start system.
For optimum service life of the battery, it is
essential to maintain an adequate state of
charge.
In some circumstances it may be necessary to
charge the battery:
-

i

f you use your vehicle essentially for short
journeys,
-

i

f the vehicle is to be taken off the road for
several weeks.
Contact a CITROËN dealer or a qualified
workshop.

In the event of a breakdown

318
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 ambient
temperature and the state of charge of
the battery (up to about 8 hours).
Do not force the lever as locking will
not be possible if the clamp is not
positioned correctly; start the procedure
again.

Disconnecting the battery
In order to maintain an adequate state
of charge for starting the engine, it is
recommended that the battery be disconnected
if the vehicle is taken out of service for a long
period.
Before disconnecting the battery:
F

c
lose all openings (doors, boot, windows,
roof),
F

s

system, wipers, lighting,
...),
F

s

At the battery, detach just the (+) terminal.Following reconnection of the battery
Following reconnection of the battery, switch on
the ignition and wait 1 minute before starting to
permit initialisation of the electronic systems.
However, if problems remain following this
operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the corresponding section, you
must yourself reinitialise (depending on
version):
