Mercedes Benz 2008 cls-class User Manual

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.

The outside temperature is displayed in 
the instrument cluster (

page 26).

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. This 
means that the accuracy of the displayed 
temperature can only be verified by com-
parison 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.

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 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.
