LUE HD I D IESEL


ENGINES
To assure respect for the environment
and conformity with the new Euro 6
emissions standard, without adversely
affecting the performance 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. 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 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.

Range indicators
When switching on the ignition, an
indicator gives an estimate of the
distance that can be travelled with
your vehicle before engine starting
is automatically prevented, once the
vehicle starts using the reserve of
AdBlue
® or after a fault is detected with
the SCR system.
In the event of simultaneous system
fault and low AdBlue
® level, the
shortest range is the one displayed.
In the event of the risk of
non-starting related to a lack of
AdBlue
®
The engine start prevention
system required by regulations is
activated automatically once the
AdBlue
® tank is empty.
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.
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 150 miles (300 km)
until the additive tank has been
topped-up.
Go to a CITROËN dealer or a qualified
workshop to have the AdBlue
® tank
topped-up.
You can also top-up the tank yourself.
Refer to the "Topping-up" section. Remaining range between 350 and
1500 miles (600 and 2 400 km)
Pressing this button
displays the driving range
temporarily.
Above 3 000 miles
(5 000 km), the value is
not specified.

The AdBlue
® tank is empty: the system
required by regulations prevents
engine starting. 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 tank.
Remaining range between 0 and
350 miles (0 and 600 km)

In the event of a fault with the SCR
emissions control systemWhen switching on the ignition, the
UREA, SERVICE and diagnostic
warning lamps comes on, accompanied
by an audible signal and the display of
a message "Emissions fault" to signal a
fault with the emissions control system.If it is a temporary fault, the alert
disappears once the exhaust gas
emissions return to normal.During an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)
A system that prevents engine
starting is activated automatically
from 650 miles (1 100 km) after
confirmation of a fault with the SCR
emissions control system. Have the
system checked by a CITROËN dealer
or a qualified workshop as soon as
possible. In the event of the detection
of a fault
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), when
switching on the ignition, 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

- 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 -
which 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). -

After emptying the bottle, wipe
away any spilla

ge 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.
-
Refit the blue cap to the tank and
turn it a 6th of a turn clockwise, to its
stop.
-

Close the filler flap. Never dispose of

bottles in the household waste.
Place them in a special container
provided this purpose or take them to
your dealer. Important: in the event of a top-
up after a breakdown because
of a lack of additive, signalled
by the message "Top up emissions
additive: Starting prevented", you must
wait around 5 minutes before switching
on the ignition, without opening the
driver's door, locking the vehicle or
introducing the key into the ignition
switch.
Switch on the ignition, then, after
10 seconds, start the engine.

ECONOMY MODE
After the engine has stopped, with
the key in the ignition position, certain
functions (windscreen wiper, electric
windows, courtesy lamps, audio
equipment, etc.) can only be used for a
cumulative duration of thirty minutes, to
prevent discharging of the battery.
Once the thirty minutes are over, the
active functions are put on standby
and the battery warning lamp flashes
accompanied by a message in the
screen.
To resume the use of these functions
immediately, start the engine and let it
run for a few minutes.
The time available will then be double
the time for which the engine was left
running. However, this time will always
be between five and thirty minutes.A flat battery will prevent the
engine from starting.
