AdBlue ® additive and SCR system
for Blue HDi 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 emissions filter (PEF) for the treatment of exhaust gases.
Presentation of the SCR system
Using an additive called AdBlue ® containing urea, ® 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 dealer to have the necessary top-up carried out.
Once the AdBlue ® tank is empty, ® 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 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.

5Practical information
When switching on the ignition, the UREA warning lamp comes on, accompanied by an audible signal and the display of a message (e.g.: "Top up emissions additive: Starting prevented in 900 miles") indicating the remaining range expressed in miles or
kilometres. When driving, the message is displayed every 150 miles (300 km) until the additive tank has been topped-up. Go to a CITROËN dealer or a qualified workshop to have the AdBlue ® tank topped-up. ® tank topped-up. ®
You can also top-up the tank yourself. Refer to the "Topping-up" section.
Remaining range between 350 and 1500 miles (600 and 2 400 km)
When switching on the ignition, the SERVICE warning lamp comes on and the UREA warning lamp flashes, accompanied by an audible signal and the display of a message (e.g. "Top up emissions additive: Starting prevented in 350 miles") indicating the remaining range
expressed in miles or kilometres. When driving, the message is displayed every 30 seconds until the additive tank has been topped-up. Go to a CITROËN dealer or a qualified workshop to have the AdBlue ® tank topped-up. ® tank topped-up. ®
You can also top-up the tank yourself. Refer to the "Topping-up" section. If you fail to do this, there is a risk that you will not be able to start your engine.
Remaining range between 0 and 350 miles (0 and 600 km)
When switching on the ignition, the SERVICE warning lamp comes on and the UREA warning lamp flashes, accompanied by an audible signal and the display of the message "Top up emissions additive: Starting prevented". The AdBlue ® tank is empty: the system required ® tank is empty: the system required ®
by regulations prevents engine starting.
Breakdown related to a lack of AdBlue ® additive
To be able to start the engine, we recommend that you call on a CITROËN dealer or a qualified workshop for the top-up required. If you carry out the top-up yourself, it is essential to add at least 3.8 litres of AdBlue ® to the tank. ® to the tank. ®
Refer to the "Topping-up" section.

If it is a temporary fault, the alert disappears once the exhaust gas emissions return to normal.
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.
When switching on the ignition, the UREA, SERVICE and diagnostic warning lamps comes on, accompanied by an audible signal and the display of a message "Emissions fault" to signal a fault with the emissions control system.
In the event of the detection of a fault
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), when switching on the ignition, 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. You should go to a CITROËN dealer or a qualified workshop as soon as possible. If you fail to do this, there is a risk that you will not be able to start your engine.
During an authorised driving phase (between 650 miles and 0 miles) (1 100 km and 0 km)

7Practical information
Every time the ignition is switched on, the SERVICE and engine diagnostic warning lamps come on and the UREA warning lamp flashes, accompanied by an audible signal and the display of the message "Emissions fault: Starting prevented".
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.
Freezing of the AdBlue ® Freezing of the AdBlue ® Freezing of the AdBlue additive

temperatures below around -11°C. The SCR system includes a heater for the AdBlue ® tank. ® tank. ®
In exceptional circumstances (vehicle kept for a long period at temperatures that are constantly below -15°C), an emissions control system fault alert may be related to freezing of the AdBlue ® in your vehicle. ® in your vehicle. ®
Park your vehicle in a warmer area for a few hours until the additive becomes liquid again. The emissions alert does not go off immediately, it will occur after several mile of running.

included in every routine service on your vehicle by a CITROËN dealer or a qualified workshop. Nevertheless, given the capacity of the tank, it may be necessary to top-up the additive between services, more particularly if an alert (warning lamps and a message) signals the requirement. You can got to a CITROËN dealer or a qualified workshop. If you envisage topping-up yourself, please read the following warnings carefully.
Precautions in use
The AdBlue ® additive is an urea-based ® additive is an urea-based ®
solution. This liquid is non-flammable, colourless and odourless (kept in a cool area). In the event of contact with the skin, wash the affected area with soap and water. In the event of contact with the eyes, wash (irrigate) the eyes with large amounts of water or with an eye wash solution for at least 15 minutes. If a burning sensation or irritation persists, get medical attention. If swallowed, immediately wash out the mouth with clean water and then drink plenty of water. In certain conditions (high ambient temperature, for example), the risk of release of ammonia cannot be excluded: do not inhale the product. Ammonia vapour has en irritant effect on mucous membranes (eyes, nose and throat).
Keep AdBlue ® out of the reach of ® out of the reach of ®
children, in its original bottle. Never transfer AdBlue ® to another ® to another ®
container: it would loose its purity.
Use only AdBlue ® additive that meets the ® additive that meets the ®
ISO 22241 standard.
Never dilute the additive with water. Never pour the additive into the Diesel fuel tank.
Never top-up from an AdBlue ®
dispenser reserved for heavy goods vehicles.
The supply in non-drip bottles simplifies toping-up. You can obtain 1.89 litre (half US gallon) bottles from a CITROËN dealer or a qualified workshop.
