Running out of fuel (Diesel)
On vehicles fitted with Diesel engines, the fuel
system must be primed if you run out of fuel.
For all versions other than BlueHDi, refer to the
corresponding engine compartment view.Other Hdi engines
(except BlueHdi version)
For more information on the Diesel
misfuel prevention device, refer to the
corresponding section.
If the engine does not start first

Checks

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

The engine start prevention system
required by regulations is activated
automatically once the AdBlue
® tank
is empty.
Range indicators
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.
In the event of the risk of non-starting related to a lack of AdBlue®
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.
With the type 2 instrument panel,
pressing this button temporarily
displays the driving range.
Above 3 000 miles (5 000 km), the value is not
specified.
Type 1 instrument panel
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 temporary display in
the instrument panel of "NO START IN" and
a distance, indicating the remaining range
expressed in miles or kilometres before engine
starting is prevented - (For example "NO
START IN 900 miles" means that "Starting will
be prevented in 900 miles).
When driving, this display appears every
150
miles (300 km) until the additive tank has
been topped-up.
Go to a dealer CITROËN or a qualified
workshop to have the AdBlue
® tank topped-up.
You can also top-up the tank yourself.

Breakdown related to a lack of AdBlue® additive
To be able to start the engine,
we recommend that you call on
a CITROËN 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 additive tank.

the AdBlue
® additive, refer to the
corresponding section.

Checks

Freezing of the AdBlue® additive
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.
If a fault with the SCR system is confirmed
(after 30 miles (50 km) covered with the
permanent display of the message signalling
a fault), the SERVICE and engine diagnostic
warning lamps come on and the UREA
warning lamp flashes, accompanied by an
audible signal and the display of a message
(e.g.: "Emissions fault: Starting prevented in
150

miles") indicating the remaining range
express in miles or kilometres.
While driving, the message is displayed every
30 seconds while the fault with the SCR system
persists.
The alert is repeated when switching on the
ignition.
You should go to a CITROËN dealer or a
qualified workshop as soon as possible.
Other wise, you will not be able to restart your
engine.

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. Never dilute the additive with water.
Never pour the additive into the Diesel
fuel tank.
Never top-up from an AdBlue®
dispenser reserved for heavy goods
vehicles.
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).
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 additive
between services, more particularly if an alert
(warning lamps and a message) signals the
requirement.
You can got to a CITROËN dealer or a qualified
workshop.
If you envisage topping-up yourself, please
read the following warnings carefully. Use only AdBlue
® additive that meets the
ISO

22241 standard.
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.
Checks

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. 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.
