Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol. It avoids
the risk of engine damage that can result from
filling with the wrong fuel.
Located in the filler neck, the misfuel
prevention device appears when the filler cap
is removed.
Misfuel prevention (Diesel)*
Operation
When a petrol filler nozzle is introduced into the
fuel filler neck of your di esel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.

cording to country of sale. It remains possible to use a fuel can to
fill the tank.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can
in direct contact with the flap of the
misfuel prevention device and pour
s l ow l y.
Travelling abroad
as
diesel fuel pump nozzles may
be different in other countries, the
presence of the misfuel prevention
device may make refuelling impossible.
Before travelling abroad, we
recommend that you check with the
CITROËN dealer network, whether your
vehicle is suitable for the fuel pumps in
the country in which you want to travel.

adblue® additive and SCR system
for

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
blu

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.

Range indicators
once the adbl ue® 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.
