Tachometer
The red marking on the tachometer
(
page 28) denotes excessive engine
speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Clock
In vehicles with Audio 20, the clock can be
set via the control system (
page 160).
Outside temperature indicator
The outside temperature is indicated in the
multifunction display (
page 141).The outside temperature sensor is located
in the front bumper area. Due to its loca-
tion, the sensor can be affected by road or
engine heat during idling or slow driving.
This means that the accuracy of the dis-
played temperature can only be verified by
comparison to a thermometer placed next
to the sensor, not by comparison to exter-
nal 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 engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
iVehicles with COMAND*:
For information on setting the time in COMAND,
refer to the separate COMAND operating
instructions.
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.

driver when traffic and road conditions
permit it to be done safely.

(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approxi-
mately 14 m) every second.
