Note!
The system stops functioning if the battery voltage falls below 12.5 Volts. This is to prevent the battery from discharging.
To activate the system, the ambient temperature must be at least 16°C. The system activation is dependant upon ambient temperature and not air
conditioning usage.
The fan runs at full speed for 10 seconds, starting 30 seconds after the ignition is turned off.
After 10 minutes the fan starts again and runs for 10 seconds.
Note!
This cycle is repeated for approximately two hours.
During this time, the fan motor will run at full speed for a maximum of two minutes in total.
If the engine is started during this time, the start system is always reset.
