outside temperature

speedometer or the outside temperature
appears in the multifunction display

G Warning!
The outside temperature indicator is not
designed to serve as an ice-warning device

freezing point do not guarantee that the
road surface is free of ice. The road may still
be icy, especially in wooded areas or on
bridges.
