AdBlue® range indicators
(BlueHDi)
The Diesel BlueHDi engines are equipped with
a system that associates the SCR (Selective
Catalytic Reduction) emissions control system
and the Diesel particle filter (DPF) for the
treatment of exhaust gases. They cannot
function without AdBlue
® fluid.
When the level of AdBlue® falls below the
reserve level (between 1,500 and 0 miles (2,400
and 0

km)), a warning lamp lights up when
the ignition is switched on and an estimate
of the distance that can be travelled before
engine starting is prevented is displayed in the
instrument panel.
The engine starting prevention system required by regulations is activated
automatically once the AdBlue
® tank is empty.
It is then no longer possible to start the
engine until the minimum level of AdBlue
® has
been topped up.
Manual display of driving range
While the driving range is greater than
1,500 miles (2,400 km), it is not displayed
automatically.
You can view the range information by pressing the " Check" button
in
the

Driving/Vehicle touch screen menu.
Actions required related to a lack of AdBlue®
The following warning lamps light up when the
quantity of AdBlue® is below the reserve level:
driving range of 1,500 miles (2,400 km).
Together with the warning lamps, messages
regularly remind you of the need to top up to
avoid engine starting being prevented. Refer to
the Warning and indicator lamps section for
details of the messages displayed.

1Malfunction of the SCR emissions
control system
Malfunction detection


If a malfunction is detected,
these warning lamps come
on, accompanied by an
audible signal and the
display of an "Emissions
control
fault" message.
The alert is triggered while driving when the
fault is detected for the first time, and thereafter
when switching on the ignition for subsequent
journeys, for as long as the cause of the fault
persists.
If the fault is temporary, the alert
disappears during the next journey, after
self-diagnostic checks of the SCR emissions
control system.
Malfunction confirmed during the
permitted driving phase (between 685
miles and 0
miles (1,100 km and 0 km))
If the fault indication is still displayed
permanently after 31 miles (50 km) of driving, the
fault in the SCR system is confirmed.
The AdBlue warning lamp flashes and
a message is displayed (" Emissions
control
fault: starting prevented in X miles
(kms)"), indicating the driving range in miles or
kilometres.
While driving, the message is displayed every 30
seconds. The alert is repeated when switching
on the ignition.
You can continue driving for up to 685 miles
(1,100
km) before the engine starting
prevention system is triggered.
Have it checked by a CITROËN dealer or
a qualified workshop.
Starting prevented
Every time the ignition is switched on, the
message "Emissions control fault: Starting
prevented" is displayed.
To restart the engine
Contact a CITROËN dealer or a qualified
workshop.

The remaining range is no longer calculated. The drive train power
gradually decreases.
The heating and air conditioning are switched
off (even if the thermal comfort consumption
indicator is not at the "ECO" level).
Flow indicator (Electric)
The flow indicator displays the energy flows in
the vehicle in real time.
It is available in the " Personal 1"/"Personal 2"
display modes of the instrument panel.
For more information on the Display modes,
refer to the corresponding section.


The indicator changes colour depending on how
energy from the traction battery is being used:
Blue: energy consumption
Green: energy recovery
This indicator does not represent the battery's actual level of charge.
Thermal comfort
consumption indicator
(Electric)
(Depending on version)
It is available in the " Personal 1"/"Personal 2"
display modes of the instrument panel.
For more information on the Display modes,
refer to the corresponding section.


The gauge shows the consumption of the
traction battery's electrical energy by the thermal
comfort devices in the passenger compartment.
The devices in question are the heating and air
conditioning systems.
This equipment can be used:
–

If the vehicle is not plugged in, when the
READY

lamp is lit.
–

If the vehicle is plugged in, when the ignition is
switched on ("Lounge" mode).
Selecting ECO

mode limits the performance of
some of this equipment. The thermal comfort
consumption indicator then moves into the
"ECO" zone.
To quickly heat or cool the passenger compartment, feel free to temporarily
select the maximum heating or cooling
setting.
When the heating is on maximum, the gauge
on the thermal comfort consumption indicator
is in the MAX zone. When the air conditioning
is on maximum, it stays in the ECO zone.
Excessive use of thermal comfort equipment,
particularly at low speed, can significantly
decrease the vehicle's range.
Remember to optimise equipment settings
upon achieving the desired level of comfort,
and adjust them if necessary whenever you
start the vehicle.
After an extended period without using the
heating, you may notice a slight odour during
the first few minutes of use.
Manual test
This function allows you to check certain
indicators and display the alerts log.
It can be accessed via the "Check" button
in the Driving/Vehicle touch screen
menu.

Practical information
AdBlue® (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
Check regularly that the terminals are correctly
tightened (versions without quick-release
terminals) and that the connections are clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Passenger compartment
filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
The start of clogging of the particle filter is
indicated by the temporary lighting of this
warning lamp, accompanied by an alert
message.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37
mph (60 km/h) until the warning lamp
goes off.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice
water vapour coming from the exhaust while
accelerating. These emissions have no
impact on the vehicle’s behaviour and the
environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.

Practical information
Timing and accessory kits
The timing and accessory kits are used
from the time the engine is started until it
is switched off. It is normal for them to wear over
time.
A
faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
AdBlue® (BlueHDi)
To respect the environment and ensure compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles with
a system that combines SCR (Selective Catalytic
Reduction) with a Diesel Particle Filter (DPF) for
the treatment of exhaust gases.
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 15 litres.
Its capacity allows a driving range of
approximately 4,000
miles (6,500 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.
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 confirmed SCR system
malfunction, it is essential to visit a CITROËN
dealer or a qualified workshop. 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 stopped.
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 first alert is issued indicating
that the reserve level has been reached.
For the correct operation of the SCR
system:
–

Use
only AdBlue
® fluid 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 qualified workshop, as well as service
stations equipped with AdBlue
® pumps specially
designed for passenger 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 fluid can be kept for
at least a year.
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
Never store AdBlue® containers in your
vehicle.
