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.
Presentation of the SCR system
Using an additive called AdBlue® containing
urea, a catalytic converter turns up to 85%
of nitrous oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment. Once the AdBlue
® tank is empty, a
s
ystem required by regulations prevents
starting of the engine.
If the SCR 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.
The AdBlue® additive is held in a special
tank located under the boot at the rear of
the vehicle. It has a capacity of 17 litres: this
provides a driving range of about 12 500 miles
(20 000 km), after which an alert is triggered
warning you when the reserve remaining is
enough for just 1 500 miles (2 400 km).
During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue
® additive tank is refilled in order to
allow normal operation of the SCR system.
If the estimated mileage between two services
is greater than 12 500 miles (20 000 km), we
recommend that you go to a CITROËN dealer
or a qualified workshop to have the necessary
top-up carried out.

Remaining range between 350 and 1500 miles (600 and 2 400 km)
When switching on the ignition, the
UREA warning lamp comes on, accompanied
by an audible signal and the display of a
message (e.g.: "Top up emissions additive:
Starting prevented in 900 miles") indicating
the remaining range expressed in miles or
kilometres.
When driving, the message is displayed every
200 miles (300 km) until the additive tank has
been topped-up.
Go to a CITROËN dealer or a qualified
workshop to have the AdBlue
® tank topped-up.
You can also top-up the tank yourself.
For more information on topping-up the
AdBlue
® additive, refer to the corresponding
section.
Remaining range between 0 and 350 miles (0 and 600 km)
When switching on the ignition, the SERVICE
warning lamp comes on and the UREA warning
lamp flashes, accompanied by an audible
signal and the display of a message (e.g.
"Top up emissions additive: Starting prevented
in 350 miles") indicating the remaining range
expressed in miles or kilometres.
When driving, the message is displayed every
30 seconds until the additive tank has been
topped-up.
Go to a CITROËN dealer or a qualified
workshop to have the AdBlue
® tank topped-up.
You can also top-up the tank yourself.
Other wise you will not be able to restart your
engine. When switching on the ignition, the SERVICE
warning lamp comes on and the UREA warning
lamp flashes, accompanied by an audible
signal and the display of the message "Top up
emissions additive: Starting prevented".
The AdBlue
® tank is empty: the system required
by regulations prevents engine starting.
Breakdown related to a lack of AdBlue® additive
To be able to start the engine,
we recommend that you call on
a CITROËN dealer or a qualified
workshop for the top-up required.
If you carry out the top-up yourself, it
is essential to add at least 3.8 litres of
AdBlue
® to the tank.

In the event of a fault with the the SCR emissions control system
A system that prevents engine starting is activated automatically from 650 miles (1 100 km) after confirmation of a fault with the SCR emissions control
system. Have the system checked by a CITROËN dealer or a qualified workshop as soon as possible.You have exceeded the authorised
driving limit: the starting prevention
system inhibits engine starting.
If it is a temporary fault, the alert
disappears during the next journey,
after self-diagnosis of the SCR system.
The UREA, SERVICE and diagnostic warning
lamps comes on, accompanied by an audible
signal and the display of the message
"Emissions fault".
The alert is triggered when driving when the
fault is detected for the first time, then when
switching on the ignition for subsequent
journeys, while the fault persists. In the event of the detection of a fault
If a fault with the SCR system is confirmed (after
30
miles (50 km) covered with the permanent display
of the message signalling a fault), the SERVICE and
engine diagnostic warning lamps come on and the
UREA warning lamp flashes, accompanied by an
audible signal and the display of a message (e.g.:
"Emissions fault: Starting prevented in 150 miles")
indicating the remaining range express in miles or
kilometres.
While driving, the message is displayed every
30
seconds while the fault with the SCR system
persists.
The alert is repeated when switching on the ignition.
You should go to a CITROËN dealer or a qualified
workshop as soon as possible.
Other wise, you will not be able to restart your engine.
During an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)
Every time the ignition is switched on, the
SERVICE and engine diagnostic warning
lamps come on and the UREA warning lamp
flashes, accompanied by an audible signal and
the display of the message "Emissions fault:
Starting prevented". Starting prevented
To be able to start the engine, you must call on
a CITROËN dealer or a qualified workshop.

Freezing of the AdBlue® additive
The AdBlue
® additive 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.
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 additive
between services, more particularly if an alert
(warning lamps and a message) signals the
requirement.
You can got to a CITROËN dealer or a qualified
workshop.
If you envisage topping-up yourself, please
read the following warnings carefully.
Topping-up the AdBlue®
additive
The AdBlue® additive is an 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 ambient
temperature, for example), the risk of release
of ammonia cannot be excluded: do not inhale
the product. Ammonia vapour has en irritant
effect on mucous membranes (eyes, nose and
throat).
Precautions in use
Keep AdBlue® out of the reach of
children, in its original bottle.
Never transfer AdBlue
® to another
container: it would lose its purity. Use only AdBlue
® additive that meets the
ISO 22241 standard.
Never dilute the additive with water.
Never pour the additive into the Diesel
fuel tank.
Never top-up from an AdBlue
®
dispenser reserved for heavy goods
vehicles.
The supply in a non-drip bottle simplifies
toping-up. You can obtain 1.89 litre (half a US
gallon) bottles from a CITROËN

dealer or a
qualified workshop.
