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.

- 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.

- 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.
- After removing the container, if there are any leaks, wipe the area around the filler opening with a damp cloth.
- 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.
