Tachometer
! Do not drive in the overrevving range, as
this could damage the engine.

engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached.
Outside temperature display
G WARNING
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
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.
The outside temperature display is in the
multifunction display (
Y
page 207).
Changes in the outside temperature are
displayed after a short delay.
