Tank level
The solution consumption varies during operations.
The level in the tank is shown on the gauge as a
percentage of the total tank volume.
When the level in the tank falls below the set limit, the
level sensor in the tank transmits a signal that stops
AUS/DEF dosing. A fault code is set in the engine
control unit, a warning lamp lights up and a fault
message is shown on the control panel.
There is a temperature sensor in the tank that transmits
a signal to the control unit so that the pump cannot start
until the AUS/DEF is fluid. AUS40 freezes at 0°C
(32°F) and AUS32 at –11°C (12°F). The system is
emptied at shut down in order to prevent expansion
damage due to freezing.
IMPORTANT:
Hoses must be handled carefully and not twisted or
bent excessively in order to avoid damaging the
heating system.
Storage
IMPORTANT:
To prevent breakdown and evaporation during
longterm storage, AUS/DEF may not be stored at
temperatures higher than 25 °C (77 °F) or in direct
sunlight. Remember that the solution expands upon
freezing and leave room expansion in the tank when
storing in spaces where there is a risk of freezing.
