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

performance 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.

The AdBlue^®additive is held in a special

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.

During each scheduled service of your vehicle

by a CITROËN dealer or a qualified workshop,

the AdBlue^®additive tank is refilled in order to

allow normal operation of the SCR system.

Presentation of the ScR system

Using an additive called AdBlue^®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.

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.

Range indicators

Once the AdBlue^®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.

Breakdown related to a lack of AdBlue^®additive

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 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

350 miles") indicating the remaining range

expressed in miles or kilometres.

When switching on the ignition, the SERVICE

warning lamp comes on and the UREA warning

lamp flashes, accompanied by an audible

The AdBlue^®tank is empty: the system required

by regulations prevents engine starting.

When driving, the message is displayed every

200 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.

You can also top-up the tank yourself.

For more information on topping-up the

AdBlue^®additive, refer to the corresponding

section.

Otherwise you will not be able to restart your

engine.

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.

AdBlue^®additive, refer to the corresponding

section.

In the event of a fault with the ScR emissions control system

In the event of the detection of a fault

during an authorised driving phase (between

650 miles and 0 miles) (1 100 km and 0 km)

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.

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.

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.

If it is a temporary fault, the alert

disappears during the next journey,

after self-diagnosis of the SCR system.

You should go to a CITROËN dealer or a

qualified workshop as soon as possible.

Otherwise, you will not be able to restart your

engine.

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.

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".

You have exceeded the authorised

driving limit: the starting prevention

system inhibits engine starting.

To be able to start the engine, you must call on

a CITROËN dealer or a qualified workshop.

Topping-up the AdBlue^®additive

Filling the AdBlue^®tank is an operation

Use only AdBlue^®additive that meets the

ISO 22241 standard.

Precautions in use

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.

The AdBlue^®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.

Never dilute the additive with water.

Never pour the additive into the Diesel

fuel tank.

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).

The supply in a non-drip bottle simplifies

toping-up. You can obtain 1.89 litre (half a US

gallon) bottles from a CITROËN dealer or a

qualified workshop.

Keep AdBlue^®out of the reach of

children, in its original bottle.

Never transfer AdBlue^®to another

container: it would lose its purity.

Never top-up from an AdBlue^®

dispenser reserved for heavy goods

vehicles.

Recommendations on storage

Procedure

AdBlue^®freezes at about -11°C and

deteriorates above 25°C. It is recommended

that bottles be stored in a cool area and

protected from direct sunlight.

Under these conditions, the additive can be

kept for at least a year.

Before topping-up, ensure that the vehicle is

parked on a flat and level surface.

In wintry conditions, ensure that the

temperature of the vehicle is above -11°C.

Otherwise the AdBlue^®may be frozen and

so cannot be poured into its tank. Park your

vehicle in a warmer area for a few hours to

allow the top-up to be carried out.

If the additive has frozen, it can be used once it

has completely thawed out.

F

Press the START/STOP button to switch

off the engine.

Never store bottles of AdBlue^®in your
