AdBlue® (BlueHDi
engines)
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment. The AdBlue
® is contained in a
special tank holding about
17 litres.
An alert system is triggered automatically once
the reser ve level is reached: you can then drive
for a further 1,500 miles (2,400 km) before the
tank is empty.
If the estimated distance travelled by your
vehicle between two ser vices is greater than
12,500 miles (20,000 km), it will be necessary
to top up the AdBlue. Once the AdBlue
® tank is empty, a system
r
equired by regulations prevents starting
of the engine.
If the SCR

system 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 travelling the distance of
685 miles (1,100 km), a system preventing
the engine starting will be triggered
automatically.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised. For more information on the Warning
and indicator lamps
and the associated
alerts, refer to the corresponding section.
Freezing of the AdBlue
®
AdBlue® 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.
Supply of AdBlue®
It is recommended that the AdBlue® be
topped up as soon as the first alert is
issued indicating that the reser ve level has
been reached.
In order to ensure that the SCR system
operates correctly:
-

U

se only AdBlue
® liquid that meets the
ISO 22241 standard.
-

N

ever transfer AdBlue
® to another
container: it would lose its purity.
-

N

ever dilute AdBlue
® with water.
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the per formance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that combines SCR (Selective
Catalytic Reduction) with a Diesel particle filter
(DPF) for the treatment of exhaust gases.

Practical information

150
You can obtain AdBlue® from a CITROËN
dealer or a qualified workshop.
You can also visit a ser vice station
equipped with AdBlue
® pumps specially
designed for private vehicles (for those
versions with access to the AdBlue
® tank
via the fuel filler flap).
Never top up from an AdBlue
® dispenser
reserved for heavy goods vehicles.
Recommendations on
storage
AdBlue® freezes at about -11°C and
deteriorates above 25°C. It should be stored in
a cool place and protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a year.
If the additive has frozen, it can be used once it
has completely thawed out.
Never keep containers or bottles of
AdBlue
® in your vehicle.
Precautions in use
AdBlue® is a 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 running water. In
the event of contact with the eyes, immediately
rinse 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 rinse the mouth with
clean water and then drink plenty of water.
In certain conditions (high temperature, for
example), the risk of releasing ammonia cannot
be discounted: do not inhale the fluid. Ammonia
vapour has an irritant effect on mucous
membranes (eyes, nose and throat).
Keep AdBlue
® out of reach of children, in
its original container or bottle.
Procedure
Before starting the top up procedure, ensure
that the vehicle is parked on a flat and level
sur face. In winter, check that the temperature of the
vehicle is above -11°C. If not, in freezing
weather, the AdBlue
® cannot be poured into the
tank. Park your vehicle somewhere warmer for
a few hours before topping up.
In the event of an AdBlue
® breakdown,
confirmed by the message "Add AdBlue:
Starting impossible", you must top up with
at least 5 litres.
Never pour AdBlue
® into the Diesel fuel
tank.
For the specifics associated with the
access configuration for the AdBlue
® tank
(via the boot or via the fuel filler flap), refer
to the descriptions given in detail further
on.
If any AdBlue
® is splashed, or if there are
any spillages on the side of the body, rinse
immediately with cold water or wipe with a
damp cloth.
If the fluid has crystallised, clean it off
using a sponge and hot water.
Practical information

151
Important: in the event of a top-up after
a breakdown because of a lack of
AdBlue, you must wait around 5 minutes
before switching on the ignition, without
opening the driver's door, locking
the vehicle, introducing the key into
the ignition switch, or introducing
the key of the

K
eyless Entr y and
Star ting system into the passenger
compartment .
Switch on the ignition, then wait for 10
seconds before starting the engine.
Access to the AdBlue® tank
via the boot
Filling the AdBlue® tank is an operation
included in every routine ser vice 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 fluid between
ser vices, as soon as an alert (warning lamps
and a message) indicates it.
You are recommended to go to a CITROËN
dealer or a qualified workshop.
If you intend to do the topping-up yourself,
read the following procedure carefully.

topping-up. F

maintenance
Recommendations on the care and
maintenance of your vehicle are given in the
Maintenance and Warranty Guide.
Leather
Leather is a natural product. Appropriate
regular care and cleaning is essential for its
durability.
Refer to your vehicle's Maintenance and
Warranty Guide for information on all the
special precautions to observe.
Care of the stickers
These styling stickers are treated to give good
resistance to ageing and tearing.
They have been designed to allow you to
customise your vehicle's bodywork.
When using a high pressure jet wash, keep the
end of the lance at least 30 centimetres from
the stickers. For the care of the stickers in the rear door
windows, we recommend the following:
-

U
se a wide jet at a temperature of
between 25°C and 40°C.
-
W
here possible, direct the jet at right
angles to the stickers.

The triangle may be stowed under the boot
carpet (in the storage box) or, depending on
version, under the front passenger seat. Before leaving your vehicle to set up and
install the triangle, switch on the hazard
warning lamps and put on your high
visibility vest.
Refer to the manufacturer's instructions on
using the triangle.
Placing the triangle
on the road
F Place the triangle behind the vehicle, as
required by the legislation in force in your
c o u nt r y.
The triangle is available as an accessory;
contact a CITROËN dealer or a qualified
workshop.
Temporary puncture
repair kit
Scan the QR code on page 3 to view
explanatory videos.
Comprising a compressor and a sealant
cartridge, it allows the temporary repair of
a tyre so that you can drive to the nearest
garage.
It is designed to repair most punctures which
could affect the tyre, located on the tyre tread
or shoulder.
Only the 12 V socket at the front of
the vehicle allows the compressor to be
connected for long enough to repair or
inflate the vehicle tyre.
The other 12 V sockets of the vehicle
are not designed to be used with the
compressor.
