SCR system
Using a liquid called AdBlue
®
that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue
®
is contained in a special
tank holding about 17 litres.
Its capacity allows a driving range of
approximately 5,500
miles (9,000 km), which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
further 1,500 miles (2,400
km) before the tank is
empty and the vehicle is immobilised.
During each scheduled service of your vehicle by
a CITROËN dealer or a qualied workshop, the
AdBlue
®
tank is relled in order to allow normal
operation of the SCR system.
If the estimated distance travelled by the
vehicle between two services is greater than
12,500 miles (20,000 km), it will be necessary to
top up the AdBlue.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators, please refer to the
corresponding sections.
Once the AdBlue
®
tank is empty, a device
required by law prevents the engine from
being restarted.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard and the vehicle starts
polluting the environment.
In the event of a conrmed SCR system
malfunction, it is essential to visit a CITROËN
dealer or a qualied workshop as soon as
possible. After 685 miles (1,100 km), a device
is automatically activated to prevent the
engine from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is immobilised.
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 very cold conditions.
Supply of AdBlue
®
It is recommended that the AdBlue
®
be topped
up as soon as the rst alert is issued indicating
that the reserve level has been reached.
For the correct operation of the SCR
system:
– Use only AdBlue
®
uid that meets the ISO
22241 standard.
– Never transfer AdBlue
®
to another container
as it would lose its purity.
– Never dilute AdBlue
®
with water.
You can obtain AdBlue
®
from a CITROËN dealer
or a qualied workshop.
You can also visit a service station
equipped with AdBlue
®
pumps specially
designed for passenger vehicles.
Never top up from an AdBlue
®
dispenser
reserved for heavy goods vehicles.
Recommendations on storage
AdBlue
®
freezes at about -11°C and deteriorates
above +25°C. Containers should be stored in a
cool area and protected from direct sunlight.
Under these conditions, the uid can be kept for
at least a year.
If the uid has frozen, it can be used once it has
completely thawed out at room temperature.
Never store AdBlue
®
containers in your
vehicle.
