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.

Range indicators
Once the AdBlue ® tank is on reserve or after ® tank is on reserve or after ®
detection of a fault with the SCR emissions control system, when the ignition is switched on, an indicator displays an estimate of the distance that can be covered, the range, before engine starting is prevented. In the event of simultaneous system fault and low AdBlue ® level, the shortest range figure is ® level, the shortest range figure is ®

When switching on the ignition, the UREA warning lamp comes on, accompanied by an audible signal and the temporary display in the instrument panel of "NO START IN" and a distance, indicating the remaining range expressed in miles or kilometres before engine starting is prevented - (For example "NO START IN 900 miles" means that "Starting will be prevented in 900 miles).

Starting prevented
Every time the ignition is switched on, the SERVICE and engine diagnostic warning lamps come on and the UREA warning lamp flashes, accompanied by the temporary display of "NO START IN" and 0 miles or kilometres - ("NO START IN 0 miles" means "Starting prevented").
To be able to start the engine, you must call on a CITROËN dealer or a qualified workshop.
You have exceeded the authorised driving limit: the starting prevention system inhibits engine starting.
In the event of a fault with the the SCR emissions control system
In the event of the detection of a fault
The UREA, SERVICE and diagnostic warning lamps comes on, accompanied by an audible signal and the display of the message "Emissions fault". The alert is triggered when driving, when the fault is detected for the first time, then when switching on the ignition for subsequent journeys, while the fault persists.
During an authorised driving phase (between 650 miles and 0 miles) (1 100 km and 0 km)
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 temporary display in the instrument panel of "NO START IN" and a distance, indicating the remaining range express in miles or kilometres before engine starting is prevented - (e.g.: "NO START IN 350 miles" means "Starting will be prevented in 350 miles").
A system that prevents engine starting is activated automatically from 650 miles (1 100 km) after confirmation of a fault with the SCR emissions control system. Have the system checked by a CITROËN dealer or a qualified workshop as soon as possible.
If it is a temporary fault, the alert disappears during the next journey, after a self diagnosis test of the SCR emissions control system.
While driving, this display appears 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.

Maintenance
In the event of a fault with the system, the "ECO OFF" switch warning lamp flashes then comes on continuously. Have it checked by a CITROËN dealer or a qualified workshop.
In the event of a fault in STOP mode, the vehicle may stall. All of the warning lamps in the instrument panel come on. It is then necessary to switch off the ignition and start the engine again using the key.
Operating fault
This system requires a battery with a special specification and technology (reference numbers available from a CITROËN dealer or a qualified workshop). Fitting a battery not listed by CITROËN introduces the risk of malfunction of the system.
Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of START mode.
The Stop & Start system makes use of advanced technology. All work on this type of battery must be done by a CITROËN dealer or a qualified workshop.
Reactivation
The system is reactivated automatically at every new start using the key.
Press the "ECO OFF" switch again. The system is active again; this is confirmed by the switch warning lamp going off, accompanied by a message in the screen.
