Operations prior to refilling
Park the vehicle on a flat surface and turn off
the ignition. If the vehicle is on a slope or on a
curb, the level indicator may not detect the
refill properly.
If a warning message about AdBlue
appears on the dash panel display, fill at
least the minimum amount required (ap-
prox. 5 litres) Only after adding this amount
will the system detect that AdBlue
added and you will be able to start the en-
gine again. The maximum amount that can
be refilled is 11 litres.
