You can deal with some problems yourself, such as a
door open or the start of saturation of the particle filter
(as soon as the traffic conditions allow, regenerate
the filter by driving at a speed of at least 40 mph
(60
km/h), until the warning lamp goes off).
For any other problems, such as a fault with the tyre
under inflation detection system, contact a CITROËN
dealer or a qualified workshop.

The petrol or Diesel engine of your vehicle is
fitted with a catalytic converter, a device which
helps to reduce the level of harmful emissions
in the exhaust gases.
For petrol engines, the use of unleaded fuel
is compulsory.
The filler neck is narrower, admitting unleaded
petrol nozzles only.

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.
AdBlue® 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 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
®.
