Reagent tank
Reagent tank
Filling the tank with reagent
Please ensure that you comply with the legislation of your country.
It is important to remember that failure to respect regulations in force could lead
to legal action being taken against the vehicle owner.
Operating principle
The reagent is intended for Diesel engines fitted with the SCR (selective catalytic reduction) system.
Using the reagent reduces the quantity of nitrogen oxides in exhaust gases.
Reagent consumption in real time depends on vehicle usage conditions, the equipment
fitted, and driving style.
Reagent quality
Use only reagents which conform to standard ISO 22241 and in accordance with the mark on the tank filler cap.
Topping up
Useful capacity of fuel tank: approximately 4.84 gal (22 litres).
With the ignition off, open the driver's door to open the flap 2. Loosen the cap 1.
Note: ammonium hydroxide vapour may escape from the cap opening when the tank temperature
is high.
Tip
Fill the vehicle tank horizontally. It is recommended to fill up.
Tip
WARNING
if the "XXX miles (XXX km)" lockout refill AdBlue message appears, fill the reagent tank
and refer to the filling instructions.
Risk of immobilisation of the vehicle.
WARNING
Fuel filler cap: this is a specific type.
If you have to replace it, make sure it is identical to the original cap. Contact
an approved Dealer. Do not wash the filler area with a high pressure washer.
Precautions for use
The tank can be filled at the pump. In other cases, it is essential to read the information
shown on the reagent container (e.g. the can or bottle).
When filling, handle the reagent with care as it can damage clothes, shoes, the bodywork, etc.
If the reagent overflows, or contaminates any paintwork, clean the affected area quickly
with plenty of cold water and a soft cloth.
Note: if the reagent fluid crystallises, use a soft sponge.
WARNING
The reagent must not come into contact with eyes or skin. If it does, wash the affected
area with plenty of cold water. If necessary, consult a doctor.
In extreme cold weather conditions
In frosty weather conditions, the reagent tank should be refilled as soon as the 
warning light and the FILL ADBLUE BEFORE 932 miles (1,500 km) or, depending on the
vehicle, the "TOP UP AdBlue before 1200 km" message is displayed on the instrument panel.
warning light and the FILL ADBLUE BEFORE 932 miles (1,500 km) or, depending on the
vehicle, the "TOP UP AdBlue before 1200 km" message is displayed on the instrument panel.
Special cases
The reagent fluid freezes below approximately -10°C.
If it is necessary to top up or fill the reagent ( on):
on):- park the vehicle in a warmer area (temperature above approximately -10°C);
- do not attempt to fill while the fluid is frozen;
- wait for the reagent to return to its liquid state (approximately eight hours);
- top up or fill with reagent.
Note: if it is not possible to apply the procedure, have an accredited professional top
up or refill the reagent.
When the vehicle is travelling in temperatures below approximately -20°C, the 
and warning lights appear on the instrument panel accompanied by the "Check injection" message. This is not necessarily a fault but related to the freezing of the fluid.
and warning lights appear on the instrument panel accompanied by the "Check injection" message. This is not necessarily a fault but related to the freezing of the fluid.
Under these conditions, follow the instructions mentioned above. Do not top up the
fluid and restart the vehicle after the reagent has returned to its liquid state.
If the warning lights and message continue to appear, there is another cause. Contact
your approved Dealer as soon as possible.
Tip
After filling the reagent tank, check that the cap and cover are closed, start the
engine and WAIT 10 seconds with the vehicle stationary and the engine running before setting off again.
If this operation is not carried out, the filling of the tank will not be taken into
account automatically until after several dozens of minutes of driving.
The "Fill AdBlue" message and/or the warning lights will continue to appear until
the filling has been registered by the system.
WARNING
No work whatsoever is permitted on any part of the system. To prevent damage, only
qualified personnel from our network may work on the system.
Alert with message on the instrument panel on display
Depending on the vehicle, the warning lights and messages on the instrument panel
3 are displayed according to the estimated range of the remaining reagent.
