To help protect the engine, the fuel supply
is interrupted if the engine is operated at
an excessive speed.
Outside temperature indicator
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
slow driving.
!Avoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
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.
