AdBlue ® additive and SCR system
for BlueHDi Diesel engines
To assure respect for the environment and conformity with the new Euro 6 emissions standard, without adversely affecting the per formance or fuel consumption of Diesel engines, CITROËN has taken the decision to equip its vehicles with an effective system that associates SCR (Selective Catalytic Reduction) with a particle filter (FAP) for the treatment of exhaust gases.
Presentation of the SCR system
Using an additive called AdBlue ® containing ® containing ®
urea, a catalytic converter turns up to 85% of nitrous oxides (NOx) into nitrogen and water, which are harmless to health and the environment.
The AdBlue ® additive is held in a special ® additive is held in a special ®
tank located under the boot at the rear of the vehicle. It has a capacity of 17 litres: this provides a driving range of about 12 500 miles (20 000 km), after which an alert is triggered warning you when the reserve remaining is enough for just 1 500 miles (2 400 km).
During each scheduled service of your vehicle by a CITROËN dealer or a qualified workshop, the AdBlue ® additive tank is refilled in order to ® additive tank is refilled in order to ®
allow normal operation of the SCR system.
If the estimated mileage between two services is greater than 12 500 miles (20 000 km), we recommend that you go to a CITROËN dealer or a qualified workshop to have the necessary top-up carried out.
Once the AdBlue ® tank is empty, a ® tank is empty, a ®
system required by regulations prevents starting of the engine. If the SCR is faulty, the level of emissions from your vehicle will no longer meet the Euro 6 standard: you vehicle becomes polluting. In the event of a confirmed fault with the SCR system, you must go to a CITROËN dealer or a qualified workshop as soon as possible: after a running distance of 650 miles (1 100 km), a system will be triggered automatically to prevent engine starting.
