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 miles 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 the 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 " Diagnostic" button
in the
touch screen’s Driving
/ Vehicle menu.
Actions required related to a lack of AdBlue®
The following warning lamps light up when the
quantity of AdBlue® is lower than the reserve
level corresponding to a 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.

Malfunction detection


If a malfunction is detected,
these warning lamps come on,
accompanied by an audible
signal and an "Emissions 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, while 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 an
"Emissions fault: Starting prevented in X
miles" or "NO START IN X miles" message is
displayed, 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 immobiliser
system is triggered.
Have the system checked by a
CITROËN dealer or a qualified workshop
as soon as possible.
