Practical Information -> AdBlue for your Citroen C5 Aircross 2017-2025
Practical information
AdBlue® (BlueHDi)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel particle filter
(DPF) for the treatment of exhaust gases.
Headlamps and lamps
Driving with under-inflated tyres increases
fuel consumption. Non-compliant tyre
pressure causes premature wear on tyres
and has an adverse effect on the vehicle's
road holding – risk of an accident!
The headlamps have polycarbonate
lenses with a protective coating.
Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
Use a sponge and soapy water.
The use of a high pressure jet wash for
cleaning the headlamps, lamps and their
surrounds may damage the lacquer and
seals.
Driving with worn or damaged tyres reduces
the braking and road holding performance of
the vehicle. It is recommended to regularly
check the condition of the tyres (tread and
sidewalls) and wheel rims as well as the
presence of the valves.
Using different size wheels and tyres from
those specified can affect the lifetime of
tyres, wheel rotation, ground clearance, the
speedometer reading and have an adverse
effect on road holding.
SCR system
Observe the recommendations on
pressure and distance for jet washing.
First clean persistent stains with a sponge
and warm soapy water.
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.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
The AdBlue® is contained in
a special tank holding about
17 litres.

Advice on care and maintenance
Recommendations on the care and
maintenance of your vehicle are given in the
Maintenance and Warranty Guide.
Leather is a natural product. Appropriate
regular care and cleaning is essential for its
durability.
Its capacity allows a driving range of
approximately 5,600 miles (9,000 km), highly
dependent on your driving style.
An alert system is triggered automatically once
the reserve level is reached: you can then drive
for a further 1,500 miles (2,400 km) before the
tank is empty.
Refer to your vehicle's Maintenance and
Warranty guide for information on all the
special precautions to observe.

Practical information
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reserve level has been reached.
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators, refer to the
corresponding sections.
Never keep bottles or containers of
AdBlue® in your vehicle.
Once the AdBlue® tank is empty, a system
required 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 a distance
of 685 miles (1,100 km), a system will be
triggered automatically to prevent engine
starting.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised.
In order to ensure that the SCR system
operates correctly:
Precautions for use
AdBlue® is a urea-based solution. This liquid
is non-flammable, colourless and odourless
(when kept in a cool place).
-
-
-
Use only AdBlue® fluid that meets the
ISO 22241 standard.
Never transfer AdBlue® to another
container: it would lose its purity.
Never dilute AdBlue® with water.
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 you feel
a persistent burning sensation or irritation, get
medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (at high temperature,
for example), the risk of release of ammonia
cannot be excluded: do not inhale the vapour.
Ammonia has an irritant effect on mucous
membranes (eyes, nose and throat).
You can obtain AdBlue® from a CITROËN
dealer or a qualified workshop.
You can also visit a service station equipped
with AdBlue® pumps specially designed for
passenger vehicles.

Recommendations on
storage
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.
AdBlue® freezes below 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.

Practical information
Access to the AdBlue® tank
A blue cap under the fuel filler flap indicates
access to the AdBlue® tank.
Keep AdBlue® out of the reach of children,
in its original container or bottle.
Important:
To avoid overflowing the AdBlue® tank, it
is recommended:
F To top up between 10 and 13 litres
using AdBlue® containers.
Or
F When filling at a service station, to stop
after the third automatic cut-off of the
nozzle.
Procedure
Before starting the top-up procedure, ensure
that the vehicle is parked on a flat and level
surface.
Do not pour AdBlue® if the temperature of the
vehicle is less than -11°C. Park your vehicle in
a warmer area for a few hours to allow the top-
up to be carried out.
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, unlocking
the vehicle, introducing the key into
the ignition switch, or introducing
the key of the Keyless Entry and
Starting system into the passenger
compartment.
F Switch off the ignition and remove the key.
Or
In the event of an AdBlue® breakdown,
confirmed by the message "Add AdBlue:
Starting impossible", you must top up with
at least 5 litres.
F With Keyless Entry and Starting, press the
"START/STOP" button to switch off the
engine.
F Turn the AdBlue® blue filler cap anti-
clockwise.
F Obtain an AdBlue® container (check the
use-by date) and pour the contents of the
container into your vehicle's AdBlue® tank.
Or
Never pour AdBlue® into the Diesel fuel
tank.
Switch on the ignition, then wait for
10 seconds before starting the engine.
F Insert the AdBlue® pump nozzle and refill
the tank until the nozzle stops automatically.
If any AdBlue® is splashed, or if there
are any spillages on the bodywork, 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.
