AdBlue® additive and SCR system
for BlueHDi Diesel engines
to assure respect for the environment and
conformity with the new
eu ro 6 emissions
standard, without adversely affecting the
per formance or fuel consumption of Diesel
engines, P
e

uge
Ot
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.
th
e 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 P
e

uge
Ot
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 P
e

uge
Ot
dealer
or a qualified workshop to have the necessary
top-up carried out. Once the AdBlue
® 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
e
u
ro 6 standard: your
vehicle becomes polluting.
In the event of a confirmed fault
with the SCR system, you must go
to a P
e

uge
Ot

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.

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.
und

er 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 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.

F Obtain a bottle of AdBlue®. After first
checking the use-by date, read carefully
the instructions on use on the label before
pouring the contents of the bottle into your
vehicle's AdBlue
® tank.
Important : if your vehicle's
AdBlue
® tank is completely empty -
w
hich is confirmed by the alert
messages and the impossibility of
starting the engine, you must add at
least 3.8 litres (so two 1.89 litre bottles). F

A
fter emptying the bottle, wipe away any
spillage around the tank filler using a damp
cloth.
If any additive is split or splashed, wash
immediately with cold water or wipe with
a damp cloth.
If the additive has crystallised, clean it
off using a sponge and hot water.

efit the boot carpet and close the tailgate. Important: when topping-up after
running out of additive
, signalled
by the message "
to
p up emissions
additive: Starting prevented", you
must wait for about 5 minutes before
switching the ignition on again, without
opening the driver's door, unlocking
the vehicle, introducing the remote
control key into the ignition switch,
or placing the electronic key of the
"Keyless Entr y and Star ting" system
inside the vehicle.
Switch on the ignition, then wait for
10 seconds before starting the engine.
Never dispose of AdBlue
® additive
bottles in the household waste. Place
them in a special container provided
this purpose or take them to your dealer.
