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.
For more information on AdBlue®
(BlueHDi) and in particular on topping
up, refer to the corresponding section.

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.
Power indicator (Electric)

CHARGE
Traction battery charging during deceleration
and braking.
ECO
Moderate energy consumption and optimised
driving range.
POWER

acceleration.
Charge level indicator
(Electric)


The traction battery's actual charge level and
the remaining range are displayed continuously
when the vehicle is started.
With the ignition off, opening the driver's
door activates the indicator.
Associated warning lamps
Two successive alert levels indicate that the
energy available has dropped to a low level:
1st level: Reserve
The state of charge of the traction battery is low.
Fixed, accompanied by an audible signal.
►

V

iew the remaining range on the instrument
panel.
►

Put the vehicle on charge as soon as
possible.
2nd level: Critical
The state of charge of the traction battery is critical.
Fixed, together with the reserve warning lamp,
accompanied by an audible signal.
►

Y

ou must put the vehicle on charge.

22
Instruments
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.
