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.
SCR system
Using a fluid called AdBlue® containing
urea, a

catalytic converter turns up to 85%
of nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment. The AdBlue
® is held in a special tank with a
capacity of about 17 litres: this provides a driving
range of about 12 500 miles (20 000 km). An
alert is triggered automatically to warn you when
the reserve level is reached: you can then drive
about 1 500 miles (2 400 km) before the tank is
e m pt y.
During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue
® tank is refilled in order to allow
normal operation of the SCR system.
If the estimated mileage of your vehicle
between two services is greater than
12 500 miles (20 000 km), it will be necessary
to top-up the AdBlue
®. Once the AdBlue
® tank is empty, a
s
ystem required by regulations prevents
starting of the engine.
If the SCR

system is faulty, the level
of emissions from your vehicle will no
longer meet the Euro 6 standard: your
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.
In either case, a range indicator gives
you the distance you can travel before
the vehicle is immobilised.

Freezing of the AdBlue®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater
for the AdBlue
® tank, allowing you
to continue driving in all weather
conditions.
Topping-up the AdBlue®
Filling the AdBlue® tank is an operation
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 fluid between
services, more particularly if an alert (warning
lamps and a message) signals the requirement.
You can go to a CITROËN dealer or a qualified
workshop.
If you envisage topping-up yourself, please
read the following warnings carefully.Precautions in use
Use only AdBlue® fluid that meets the
ISO

22241 standard.
AdBlue® is a 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 temperature, for
example), the risk of release of ammonia
cannot be excluded: do not inhale the fluid.
Ammonia vapour has an irritant effect on
mucous membranes (eyes, nose and throat). The supply in a non-drip container or bottle
simplifies topping-up. You can obtain 1.89 litre
(half a US gallon) bottles or 5 litre containers
from a CITROËN
dealer or a qualified
workshop. Never dilute AdBlue
® with water.
Never pour AdBlue® into the Diesel fuel
tank.
Never top-up from an AdBlue
®
dispenser reserved for heavy goods
vehicles.
Keep AdBlue
® out of the reach of
children, in its original container or
bottle.
Never transfer AdBlue
® to another
container: it would lose its purity.

281
Recommendations on storage
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 fluid can be kept
for at least a year.
If the additive has frozen, it can be used once it
has completely thawed out.
Procedure
Before topping-up, ensure that the vehicle is
parked on a flat and level sur face.
In wintry conditions, ensure that the
temperature of the vehicle is above -11°C.
Other wise, by freezing, the AdBlue
® 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.

Practical information

282
Important: if your vehicle's AdBlue®
tank is completely empty - which is
confirmed by the alert messages and
the impossibility of starting the engine,
you must add at least 3.8 litres of fluid. Important:
when topping-up after
running out of AdBlue®, signalled
by the message "Top-up AdBlue:
Starting prevented", you must wait
for approximately 5 minutes before
switching on the ignition, without
opening the driver's door, unlocking
the vehicle, placing the key of the
"Keyless Entr y and Star ting" system
inside the vehicle or inser ting the
electronic key in the reader.
Switch on the ignition, wait for
10

seconds, then start the engine.
If any fluid is spilt or splashed, wash
immediately with cold water or wipe with
a damp cloth.
If the fluid has crystallised, clean it off
using a sponge and hot water.

This kit is installed in the storage box, under the
boot floor.This kit consists of a compressor and a sealant cartridge.
It allows the temporary repair
of a tyre.
You are then able to go to the nearest garage.
It is designed to repair most punctures which could affect the tyre, located on the tyre tread or
shoulder.
Its compressor can be used to check and adjust the pressure of the tyre.
