ICE
This warning means that there might be ice on the
road, due to a low temperature.
Warning is activated when the instrument panel
detects a temperature of 4°C (39°F) or lower than
that. Warning will be disabled as soon as
temperature rises up to 6°C (43°F).
Attention
This warning does not exclude the fact that
there may be some ice on the road also if
temperature is higher than 4 °C (39 °F). When the
temperature is low, it is recommended to always ride
with great care, especially on path sections not under
the sun and/or bridges.
