Before topping up, make sure the vehicle is on a flat, level surface.

In winter, make sure the vehicle temperature is above -11°C.

Otherwise, frozen AdBlue cannot be poured into the tank. Park the vehicle in a warmer area for several hours to allow topping up.

  • Switch the ignition off and remove the key.
Procedura

  • To access the AdBlue tank, lift the boot floor covering, then, depending on equipment, remove the spare wheel and/or the container.
  • Turn the black cap one quarter turn anticlockwise without pressing it, then pull it up and remove it.
  • Turn the blue cap one sixth of a turn anticlockwise.
  • Pull the cap up and remove it.
Procedura

  • Obtain an AdBlue container.

    Before using the sealant, check the expiry date. Before pouring the contents of the container into the tyre repair kit's tank, carefully read the instructions on the label.

Important: if the AdBlue tank in the vehicle has been completely emptied - as confirmed by warning messages and the engine being unable to restart - be sure to add at least 3.8 litres (i.e. two 1.89-litre containers).
  • After removing the container, if there are any leaks, wipe the area around the filler opening with a damp cloth.
In case of splashes, rinse immediately with cold water or wipe with a damp cloth. If the additive has crystallised, remove it using a sponge and hot water.
  • Place the blue cap on the tank outlet and turn it 1/6 of a turn clockwise, until it stops.
  • Fit the black cap and turn it a quarter turn clockwise, without pressing down on it.

    Check that the cap indicator is aligned with the indicator on the housing.

  • Depending on equipment, put the spare wheel and/or the container back in its place in the boot floor.
  • Put the boot mat back in place and close the tailgate.
Important: when topping up after the additive has run out, indicated by the message "Refill exhaust treatment additive: Starting prohibited", be sure to wait about 5 minutes before switching the ignition back on, without opening the driver's door, unlocking the vehicle or inserting the key into the ignition. Switch on the ignition, then start the engine after 10 seconds. Do not dispose of empty AdBlue containers with household waste. Place them in a designated container or return them to a point of sale.
