128 Controls in detailInstrument clusterTachometer
The red marking on the tachometer de-
notes excessive engine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
CL 55 AMG
The tachometer of the CL 55 AMG does
not have a red marking denoting excessive
engine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated at
an excessive engine speed.
Outside temperature indicator
The outside temperature is displayed in
the instrument cluster (
page 22). For in-
formation on how to select the unit of the
displayed temperature, i.e. degrees
Celsius (°C) or degrees Fahrenheit (°F),
see “Selecting temperature display mode”
(
page 148).The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. There-
fore, the accuracy of the displayed temper-
ature can only be verified by comparison to
a thermometer placed next to the sensor,
not by comparison to external 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
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.
