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.

control system
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.
