Tachometer
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.
S 55 AMG
The tachometer of the S 55 AMG does not
have a red marking denoting excessive en-
gine 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 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-

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.

Indicated temperatures just above the freez-

face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
