At temperatures just above freezing point, the
street may be icy, especially in wooded areas
or on bridges. If you do not adapty our driving
style to the conditions, the vehicle could skid.
For this reason, adapt your driving style and
speed to the weather conditions.
Changes in the outside temperature are dis-
played after a short delay. Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
