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, PEUGEOT 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
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
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 PEUGEOT dealer or a qualified workshop,
the AdBlue
® 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 PEUGEOT dealer
or a qualified workshop to have the necessary
top-up carried out. Once the AdBlue
® 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 PEUGEOT 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
The engine start prevention system
required by regulations is activated
automatically once the AdBlue
® tank is
e m pt y.
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.
In the event of simultaneous system fault and
low AdBlue
® level, the shortest range figure is
the one displayed. Range greater than 1 500 miles (2 400 km)
When the ignition is switched on, no
information on range is displayed automatically
in the instrument panel.
Pressing this button displays the driving range
temporarily.
Above 3 000 miles (5 000 km), the value is not
specified.

Remaining range between 350 and 1500 miles (600 and 2 400 km)
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
200 miles (300 km) until the additive tank has
been topped-up.
Go to a PEUGEOT 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.
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 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 PEUGEOT dealer or a qualified
workshop to have the AdBlue
® tank topped-up.
You can also top-up the tank yourself.
Other wise you will not be able to restart your
engine.
Breakdown related to a lack of AdBlue® additive
For more information on topping-up
the AdBlue® additive, refer to the
corresponding section. To be able to start the engine,
we recommend that you call on a
PEUGEOT 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.
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
by regulations prevents engine starting.

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 an audible signal and
the display of the message "Emissions fault:
Starting prevented".
Freezing of the AdBlue
® additive
To be able to start the engine, you must call on
a PEUGEOT dealer or a qualified workshop. 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.

Topping-up the AdBlue® additive
Precautions in use
Keep AdBlue® out of the reach of
children, in its original bottle.
Never transfer AdBlue
® to another
container: it would lose its purity. Use only AdBlue
® additive that meets the
ISO

22241 standard.
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. Ammonia vapour has en irritant
effect on mucous membranes (eyes, nose and
throat). Never dilute the additive with water.
Never pour the additive into the Diesel
fuel tank.
The supply in a non-drip bottle simplifies
toping-up. You can obtain 1.89 litre (half a US
gallon) bottles from a PEUGEOT
dealer or a
qualified workshop.
Never top-up from an AdBlue
®
dispenser reserved for heavy goods
vehicles.
Filling the AdBlue
® tank is an operation
included in every routine service on your
vehicle by a PEUGEOT 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 PEUGEOT dealer or a
qualified workshop.
If you envisage topping-up yourself, please
read the following warnings carefully.

Never store bottles of AdBlue® in your
vehicle.
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 additive 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.
Otherwise, 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.

pressure of the spare wheel checked
by a PEUGEOT dealer or a qualified
workshop.
