Outside temperature indicator
The outside temperature is indicated in the
multifunction display (
page 141).The outside temperature sensor is located
in the front bumper area. Due to its loca-
tion, the sensor can be affected by road or
engine heat during idling or slow driving.
This means that the accuracy of the dis-
played temperature can only be verified by
comparison to a thermometer placed next
to the sensor, not by comparison to exter-
nal displays (e.g. bank signs etc.).
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or

The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
