.&_ WARNING
-
-Never rely exclusively on the outside
temperature display to determine if a road surface is icy or not. Keep in mind
that road surfaces, especially bridges and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F (+5 °().
- Always reduce your speed and drive with
special care in cold weather conditions
when the chance of encountering icy
road surfaces increases.
(D Tips
-You can select the un its used for temper·
ature, speed and other measurements in
the
MMI.
- If the vehicle is stat ionary, or if you are
driving at a
very low speed, the tempera
ture shown in the display might be
slightly higher than the actual outside temperature.
This is caused by the heat
being radiated from the engine.
- At temperatures below 41 °F
(+ 5 °C) a
snowf lake symbol appears ahead of the
temperature display
