Fuel

The use of B20 or B30 fuel

meeting standard EN16709

is possible in your Diesel

engine. However, this use,

even occasional, requires

strict application of the special

servicing conditions referred to

as "Arduous conditions".

travelling abroad

certain fuels could damage the

engine of your vehicle. In certain

countries, the use of a particular fuel

may be required (specific octane rating,

specific sales name…) to ensure correct

operation of the engine.

Fuel used for diesel engines

The Diesel engines are compatible with

biofuels that conform to current and future

European standards and can be obtained

from filling stations:

Far any additional information, contact the

dealer.

-

Diesel fuel that meets

standard EN590 mixed

with a biofuel that meets

standard EN14214 (possibly

containing up to 7 % Fatty

Acid Methyl Ester),

For more information, contact a CITROËN

dealer or a qualified workshop.

The use of any other type of (bio)

fuel (vegetable or animal oils, pure or

diluted, domestic fuel...) is strictly prohibited

(risk of damage to the engine and fuel

system).

Diesel fuel that meets

standard EN16734 mixed

with a biofuel that meets

standard EN14214 (possibly

containing up to 10 % Fatty

Acid Methyl Ester),

The only Diesel additives authorised for

use are those that meet the B715000

standard.

-

Paraffinic Diesel fuel that

meets standard EN15940

mixed with a biofuel that

meets standard EN14214

(possibly containing up

to 7 % Fatty Acid Methyl

Ester).

Fuel

To restore the fuel supply, press the first

FuEL SYStEM cut-OFF

button located under the glove box.

In the event of a collision, a device

automatically cuts off the fuel supply to the

engine and the vehicle's electrical supply.

It switches on the hazard warning lamps and

the courtesy lamps, as well as unlocking the

doors.

Following an impact and before

restoring the supply, check that there is

no leak of fuel or sparks so as to avoid any

risk of fire.

Then, to restore the electrical power supply,

press the second button, located in the

battery compartment under the driver's floor

(Minibus).

On other versions the second button is

replaced by a fuse; contact a CITROËN

dealer or a qualified workshop.

AdBlue^®

BLuEHdI And AdBLuE^®

Scr technology

The aim of BlueHDi is to reduce the

emissions of NOx (nitrous oxides) in the

air by up to 90%, using a system that

converts NOx into water vapour and nitrogen

in a dedicated catalytic converter: SCR

(Selective Catalytic Reduction).

This objective meets the "Euro 6" emissions

standard adopted by the European Union

aimed at limiting the emissions of pollutants

from internal combustion engines.

AdBlue^®is the brand name of the solution

needed for operation of the SCR system.

The SCR technology used on BlueHDi

engines involves the injection of AdBlue^®

into the exhaust system.

This solution is a urea-based fluid.

BlueHDI vehicles have a specific AdBlue^®

additive tank with a capacity of 15 litres.

This fluid is non-flammable, colourless and

odourless.

It has an exterior filler located behind the

fuel filler flap below the fuel filler cap and

closed with a blue filler cap.

AdBlue^®

Filling the AdBlue tank

Good practice

Filling of the AdBlue^®tank can be done

using:

Once the AdBlue level drops to the reserve

level, you are warned by different temporary

signals (warning lamp, message, audible

signal).

When the AdBlue^®tank is empty, restarting

becomes impossible.

-

5 or 10 litres containers equipped with a

10 centimetre filler tube or the filling kit

available from CITROËN dealers,

1.89 litre bottles that are screwed onto

the filler neck, available from CITROËN

dealers,

It is strongly recommended that you do

not wait for the successive alerts, but

top-up the AdBlue^®as soon as possible.

or when at a fuel filling station equipped

with a special AdBlue^®delivery pump for

heavy or light vehicles.

This operation can also be carried out

by a CITROËN dealer or a qualified

workshop.

These bottles and containers are available

from CITROËN dealers.

To facilitate filling, an adaptor is also

available from CITROËN dealers.

range indicators

Different levels of alert are triggered

according to the remaining driving range

threshold.

remaining range less than 350 miles

(600 km) and more than 0 miles

Starting prevented - Breakdown related to

a lack of AdBlue^®in the special tank

Once the 350 miles (600 km) threshold

is reached, this warning lamp ﬂashes,

accompanied by a message on the

remaining driving range.

0 miles operating range reached: the system

installed in the vehicle to meet the emissions

standard will prevent engine starting.

You will be informed as each mileage

threshold is reached and the alerts will

change from temporary to permanent.

Your vehicle's exhaust emissions no longer

meet the "Euro 6" standard and the engine will

not start.

Unless the AdBlue^®is topped-up in the

special additive tank, the vehicle will remain

immobilised.

driving range of 1 500 miles (2 400 km).

-

The 2^ndalert is triggered at a remaining

driving range of 375 miles (600 km).

Every time the ignition is switched on, the alert is

given together with an audible signal.

Up to 0 miles, at which point it will be

impossible to restart the engine after a stop.

To be able to restart the vehicle, you must:

top-up the AdBlue^®with at least

range greater than 1 500 miles (2 400 km)

-

workshop.

remaining range less than 1 500 miles

(2 400 km) and greater than 375 miles

(600 km)

Following this, make a further fill to the

special additive tank, the capacity of

which is 15 litres.

Once the 1 500 miles (2 400 km)

threshold is reached, this warning

lamp comes on temporarily and the

remaining range message is displayed.

Every time the ignition is switched on, the

alert is given, together with an audible

signal.

Fault with the Scr system

detection

Fault confirmed

Starting prevented, having covered the

250 miles (400 km)

In addition to the previous signals, the

remaining range allowed will be displayed in

miles (kilometres) in the instrument panel.

The diagnostic warning lamp

comes on.

At each attempt at starting,

the alert is activated and the

message on starting prevention is

displayed.

Every time the ignition is

switched on, the emissions fault

is confirmed by an audible signal and a

message.

The alert will be repeated every 30 seconds

with an update of the driving range.

Go to a CITROËN dealer or a qualified

workshop as soon as possible.

If it is a temporary fault, the alert disappears

as soon as the exhaust emissions return to

the levels required by the standard.

You risk not being able to start the engine.

On the other hand, if the warning lamp

is still on after 30 miles (50 km) of

driving, the fault is confirmed.

An engine start prevention system

will be activated automatically after

250 miles (400 km) travelled following this

confirmation.

Go to a CITROËN dealer or a qualified

workshop.
