adblue® additive and SCR system

esel 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
d
i
esel
engines, CITR
oËn

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 adbl ue® 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.
on
ce the a
dbl
ue
® tank is empty, a
s
ystem 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 CITR
oËn

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.
The
a
dblu
e® 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).
du

ring each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the
a
d

e
® 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 CITR
oËn

dealer
or a qualified workshop to have the necessary
top-up carried out.

163
Filling the adblue® tank is an operation
included in every routine service on your
vehicle by a CITR
oËn

dealer or a qualified
workshop.
ne

vertheless, 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 CITR
oËn

dealer or a qualified
workshop.
If you envisage topping-up yourself, please
read the following warnings carefully.
Topping-up the AdBlue® additive
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.
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.
a
m
monia vapour has en irritant
effect on mucous membranes (eyes, nose and
throat).
Precautions in use
keep a dblu e® out of the reach of
children, in its original bottle.
ne

ver transfer a d
blu
e
® to another
container: it would lose its purity. Use only
a d
blu
e
® additive that meets
the ISO 22241 standard.
Never dilute the additive with water.
ne

ver pour the additive into the d
i
esel
fuel tank.
ne

ver top-up from an a
dbl
ue
®
dispenser reserved for heavy goods
vehicles.
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.
