DS 3: AdBlue® (BlueHDi) / Supply of AdBlue®

DS 3 2016-2023 Owners Manual

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.

DS 3. Supply of AdBlue® For the correct operation of the SCR system:

  • Use only AdBlue® fluid that meets the ISO 22241 standard.
  • Never transfer AdBlue® to another container as it would lose its purity.
  • Never dilute AdBlue® with water.

You can obtain AdBlue® from a dealer or a qualified workshop, as well as service stations equipped with AdBlue® pumps specially designed for passenger vehicles.

Recommendations on storage

AdBlue® freezes at about -11°C and deteriorates above +25°C. Containers should be stored in a cool area and protected from direct sunlight. Under these conditions, the fluid can be kept for at least a year.

If the fluid has frozen, it can be used once it has completely thawed out at room temperature.

DS 3. Supply of AdBlue® Never store AdBlue® containers in your vehicle.

Precautions for use

AdBlue® is a urea-based solution. This fluid is nonflammable, colourless and odourless (when kept in a cool place).

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. Seek medical attention if you feel a persistent burning sensation or irritation.

If swallowed, immediately wash out the mouth with clean water and then drink plenty of water.

In certain conditions (high temperature, for example), the risk of release of ammonia cannot be excluded: do not inhale the fluid. Ammonia vapours have an irritant effect on mucous membranes (eyes, nose and throat).

DS 3. Supply of AdBlue® Store AdBlue® out of the reach of children, in its original container.


Before starting the top-up procedure, 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 the AdBlue® may be frozen and so cannot be poured into the tank. Park the vehicle in a warmer area for a few hours to allow the top-up to be carried out.

DS 3. Supply of AdBlue® Never pour the AdBlue® into the Diesel fuel tank.

DS 3. Supply of AdBlue® 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.

DS 3. Supply of AdBlue® Important: in the event of a top-up after an AdBlue breakdown, you must wait about 5 minutes before switching on the ignition, without opening the driver's door, unlocking the vehicle or bringing the electronic key into the passenger compartment.

Switch on the ignition, then wait for 10 seconds before starting the engine.

  • Press the "START/STOP" button to switch off the engine.

DS 3. Supply of AdBlue®

  • Turn the blue cap of the AdBlue® tank anticlockwise and remove it.
  • With a container of AdBlue®: after checking the expiry date, read the instructions on the label carefully before pouring the contents of the container into the vehicle's AdBlue tank.
  • With an AdBlue® pump: insert the nozzle and fill the tank until the nozzle automatically cuts out.

DS 3. Supply of AdBlue® In order not to overfill the AdBlue® tank:

Add between 10 and 13 litres using AdBlue® containers.

Stop after the nozzle’s first automatic cutout, if you are refilling at a service station.

The system only registers AdBlue® top-ups of 5 litres or more.

DS 3. Supply of AdBlue® If the AdBlue® tank is completely empty – which is confirmed by the message “Top up AdBlue: Starting impossible” – it is essential to add at least 5 litres.

DS 3. Supply of AdBlue® Do not dispose of AdBlue® containers in the household waste.

Place them in a container reserved for this purpose or take them back to where you bought them.
