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.
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 range is greater than 1,500 miles
( 2,400 km), it is not displayed automatically.
F

P
ress this button to temporarily display the
driving range.
Actions required related to a lack
of AdBlue®
The following warning lamps light up when the
quantity of AdBlue® is lower than the reser ve
level corresponding to a range of 1,500 miles
(2, 4 0 0


k m).
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 of the SCR
emissions control system
Malfunction detection
If a malfunction is detected,
t hese warning lamps come on,
accompanied by an audible signal
and the display of an "Emissions
fault" message.
The alert is triggered while driving as soon
as the fault is detected for the first time, then
when switching on the ignition for subsequent
journeys, while the fault persists. If it is a
temporary fault, 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 warning lamp is still on after 31 miles
( 50 km) of driving, the fault in the SCR system
is confirmed. Have the system checked by a
CITROËN
dealer or a qualified workshop as soon as
possible.
Starting prevented
Every time the ignition is switched on, the
message "Emissions fault: Starting prevented"
is displayed.
To be able to restart the engine, call
on a
CITROËN dealer or a qualified
workshop.
The AdBlue warning lamp flashes,
accompanied by the display of a
message
("Emissions fault: Starting prevented in x
miles") indicating the remaining 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 star ting
prevention system is triggered.
