The outside temperature is measured by the front SAM control unit with fuse and relay module (N10/1) through the outside temperature sensor (B14) and shown on the instrument cluster (A1).

If the front SAM control unit receives the displayed outside temperature of T < 5 °C from the instrument cluster, then the spray nozzle heater (R2/1) and spray nozzle hose heater (R2/11) are switched on by the front SAM control unit.
If the outside temperature shown on the instrument cluster rises to T > 8 °C, the spray nozzle heater and spray nozzle hose heater are switched off by the front SAM control unit.

When the outside temperature value sent by the instrument cluster malfunctions, the front SAM control unit refers to its own temperature value.
