Warning / indicator lampStateCause Action / Observations
Engine fault Fixed orange. The engine has a minor fault. Contact a CITROËN dealer or a qualified workshop
without delay.
Low fuel level Fixed. When it first comes on, around
5
litres of fuel remain in the tank.You must top up as soon as possible to avoid running
out of fuel.
This warning lamp will come on every time the ignition
is switched on, until sufficient fuel is added.
Fuel tank capacity: approximately 50
litres.
Never continue to drive until you run out of fuel as
this could damage the emission control and injection
systems.
Engine auto
diagnosis
system Fixed.
The emission control system has a
fault.
The warning lamp should go off when the engine is started.
If it does not go off, contact a CITROËN dealer or a
qualified workshop without delay.
Flashing.The engine management system has
a fault.There is a risk that the catalytic converter will be destroyed.
Have the system checked by a CITROËN dealer or a
qualified workshop.
Diesel engine
pre-heatingFixed.
The key is at position 2 (ignition on)
in the ignition switch. Wait until the warning lamp goes off before starting.
The period of illumination of the warning lamp is
determined by the ambient conditions (up to about
thirty seconds in extreme conditions).
If the engine does not start, switch the ignition off and
then on, wait until the warning lamp goes off again,
then start the engine.

AdBlue® (BlueHDi
engines)
SCR System
Using a fluid called AdBlue® that contains
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 special tank

with a capacity of around 17 litres. This
capacity allows a driving range of around
12,000

miles (20,000 km). An alert system is
triggered automatically once the reser ve level
is reached: you can then drive for a further
1,500

miles (2,400 km) before the tank is
completely empty.
During each scheduled ser vice 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 distance travelled by your
vehicle between two ser vices is greater than
12,000

miles (20,000 km), it will be necessary
to top up the AdBlue.
To respect the environment and ensure
compliance with the new Euro 6

standard,
without adversely affecting the performance or
fuel consumption its diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a particle filter (DPF)
for the treatment of exhaust gases. 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 shows the
distance you can travel before the vehicle
is immobilised.
For more information on the Warning
lamps and the associated alerts, refer to
the corresponding section.
Filling the AdBlue
® tank is an operation
included in every routine ser vice on your
vehicle by a CITROËN dealer or a qualified
workshop.
