When topping off AUS/DEF a nozzle with a built-in
shut-off function should be used in accordance with
ISO standard 18611 and ISO standard 22241. These
nozzles are designed not to fit any other filling
equipment.
The tank cover is blue and marked with the text 'AUS/
DEF only' to avoid confusion when filling.
The ratio between the consumption of AUS/DEF and
diesel is dimensioned as at least 1:1 to avoid the
solution's running out before the diesel.
Never fill with AUS/DEF other than ISO 18611 and
ISO 22241 as specified by Volvo.
If this instruction is not followed the aftertreatment
system may be permanently damaged. Engine power
may also be affected negatively and engine
components risk damage. Damage and costs arising
from a failure to meet these requirements are not
covered by Volvo Penta warranty obligations.
If AUS/DEF is filled from a can or pump that lacks a
stop function, it is important to make sure the tank is
not overfilled as the solution may leak out of the
breather tube. If the tank is overfilled and the solution
in it freezes at temperatures below -1 °C (12.2 °F), the
tank and the hoses may be permanently damaged.
Take great care not to spill the solution as it is
extremely corrosive toward many materials. If a spill
should occur the solution must be absorbed using dry
sand or other non-flammable material and handled
according to local and national regulations. Avoid spills
onto soil and into waterways.
