Freezing of the AdBlue® additive
The AdBlue
® additive freezes at 
temperatures below around -11°C.
The SCR system includes a heater 
for the AdBlue
® tank, allowing you to 
continue driving in very cold conditions.
If a fault with the SCR system is confirmed  
(after 30 miles (50 km) covered with the 
permanent display of the message signalling 
a fault), the SERVICE and engine diagnostic 
warning lamps come on and the UREA 
warning lamp flashes, accompanied by an 
audible signal and the display of a message 
(e.g.: "Emissions fault: Starting prevented in 
150
 
miles") indicating the remaining range 
express in miles or kilometres.
While driving, the message is displayed every 
30 seconds while the fault with the SCR system 
persists.
The alert is repeated when switching on the 
ignition.
You should go to a CITROËN dealer or a 
qualified workshop as soon as possible.
Other wise, you will not be able to restart your 
engine.
