the Mercedes-Benz Limited Warranty.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.

Outside temperature indicator
Warning!
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.
The outside temperature is indicated in the
multifunction display ( page 144).
The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
G
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.
