Ice
This function warns the rider when there might be ice
on the road, due to the low external temperature.
This warning turns on when temperature drops to
4°C (39°F) and turns off when temperature raises to
6°C (43°F).
Warning
This warning does not eliminate the possibility
of icy road areas even with temperatures above 4°C
(39°F); when ambient temperature is "low", ride
responsibly, especially on road areas not exposed to
sunlight and/or on bridges.
