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.
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.
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 equipped with the
SCR
(selective catalytic reduction).
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 the reagent fluid that complies with the standard ISO 22241 and in accordance with the marking on the tank cap.
Topping up
Useful capacity of tank: approximately 4.62 gal (21 l) or 6.16 gal (28 l) (depending on the vehicle).
With the ignition off, open the front passenger 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
To fill up with reagent, the engine must be stopped (not just on standby in the case
of vehicles equipped with the
Stop and Start
). You must switch off the ignition STARTING, STOPPING THE ENGINE, STOP AND START FUNCTION.
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.
In extreme cold weather conditions
In freezing conditions, fill the reagent tank as soon as the 
warning light and the "Fill AdBlue before 932 miles (1,500 km)" or, depending on the vehicle, the "Fill AdBlue before 745 miles (1,200 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 "Fill AdBlue before 745 miles (1,200 km)" message is displayed on the instrument panel.
Special cases
The reagent fluid freezes below approximately -10°C.
In these conditions, do not attempt filling when the fluid is frozen. If it is necessary
to top up or fill the reagent ( on), park the vehicle in a warmer area so that the reagent returns to its liquid
state. Otherwise, have a qualified professional top up or fill up with reagent fluid.

state. Otherwise, have a qualified professional top up or fill up with reagent fluid.
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, 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.
