Ice warning
If the outside temperature drops to
about 37.5 7 (+3 6), then the
computer will automatically switch to a
display of the outside temperature. In
addition, a signal sounds as a warning
and the display flashes for a brief
period.
The ice warning does not alter the
fact that surface ice can form at
temperatures above 37.5 7 (+3 6), on
bridges or shaded road surfaces, for
