Practical information -> AdBlue? additive and SCR system for Your Citroen C3 SUV Second Generation (2009-2016)

Practical information  
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  
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.  
The adblue® additive is held in a special  
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  
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.  
(1 100 km), a system will be triggered  
automatically to prevent engine starting.  
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.  
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.

Practical information  
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.  
The engine start prevention system  
required by regulations is activated  
automatically once the adblue® tank is  
empty.  
depending on your vehicle's equipment, the  
range indicator will appear either:  
-
in the instrument panel screen (versions  
without audio system), or  
-
in the multifunction screen.

Practical information  
Topping-up the AdBlue® additive  
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.  
Precautions in use  
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.  
Use only adblue® additive that meets  
the ISO 22241 standard.  
Never dilute the additive with water.  
never pour the additive into the diesel  
fuel tank.  
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).  
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.  
11  
keep adblue® out of the reach of  
children, in its original bottle.  
never transfer adblue® to another  
container: it would lose its purity.  
never top-up from an adblue®  
dispenser reserved for heavy goods  
vehicles.  
163  
Practical information  
Recommendations on storage  
Procedure  
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.  
before topping-up, ensure that the vehicle is  
parked on a flat and level surface.  
In wintry conditions, ensure that the  
temperature of the vehicle is above -11°C.  
Otherwise, by freezing, the AdBlue® 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.  
If the additive has frozen, it can be used once it  
has completely thawed out.  
never store bottles of adblue® in your  
vehicle.  
F
F
For access to the adblue® tank, raise the  
boot carpet then, depending on equipment,  
lift out the spare wheel and/or the storage  
box.  
Without pressing, turn the black cap a  
quarter turn anti-clockwise and lift it off.  
F
F
Turn the blue cap a 6th of a turn anti-  
clockwise.  
Lift off the cap.

Practical information  
F
After emptying the bottle, wipe away any  
spillage around the tank filler using a damp  
cloth.  
Important: in the event of a top-  
up after a breakdown because of  
a lack of additive, 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.  
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.  
F
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.  
Switch on the ignition, then, after  
10 seconds, start the engine.  
F
F
Refit the blue cap to the tank and turn it a  
6th of a turn clockwise, to its stop.  
Refit the black cap and turn it a quarter of  
a turn clockwise without pressing. Ensure  
that the indicator on the cap lines up with  
the indicator on the support.  
never dispose of adblue® additive  
bottles in the household waste. Place  
them in a special container provided  
this purpose or take them to your dealer.  
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).
