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 of the SCR emissions

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.
Starting prevented
Whenever the ignition is switched on, the 
"Emissions fault: Starting prevented" or "NO 
START IN" message is displayed.
To be able to restart the engine, contact  a CITROËN dealer or a qualified 
workshop.

Range
(miles or km)The distance which can still be travelled  with the fuel remaining in the tank (related 
to the average fuel consumption over the last 
few miles (kilometres) travelled).
This value may fluctuate if a change of  driving style or terrain results in a 
significant change in the current fuel 
consumption.
Dashes are displayed when the range falls below 
20 miles (30km).
After filling with at least 5 litres of fuel, the range 
is recalculated and is displayed if it exceeds 60 
miles (100 km).
If dashes instead of figures continue to 
be displayed when driving, contact a 
CITROËN dealer or a qualified workshop.
Current fuel consumption
(mpg or km/l or l/100 km)Calculated over the last few seconds.
