AdBlue® and SCR system for BlueHDi Diesel engines
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 contained in a specific tank
of approximately 17 litres. Its capacity allows
a driving range of around 12,500 miles
(20,000

km). An alert system is triggered
automatically once the reserve level is reached:
you can then drive for a further 1,500 miles
(2,400 km) before the tank is empty.
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 system
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.
SCR system
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 the SCR system (Selective Catalytic
Reduction) with a particle filter (FAP) for the
treatment of exhaust gases.

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.
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.
Precautions in use
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 copiously under running 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
fluid. Ammonia vapour has an irritant effect on
mucous membranes (eyes, nose and throat).
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. Use only AdBlue
® fluid that meets the
ISO
22241 standard.
Never dilute AdBlue
® with water.
Never pour AdBlue® into the Diesel fuel
tank.
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 top-up from an AdBlue
® dispenser
reserved for heavy goods vehicles.
