position1 or 2.

Call up the trip odometer and main
odometer by pressing button è
or ÿ on the multifunction steering
wheel (
page 110).

Press button j ork until the
coolant temperature display appears. During severe operating conditions e.g.
stop-and-go city traffic, the coolant tem-
perature may rise close to 248°F (120°C).
The engine should not be operated with
the coolant temperature above 248°F
(120°C). Doing so may cause serious en-
gine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G


Driving when your engine is badly over-
heated can cause some fluids which
may have leaked into the engine com-
partment to catch fire. You could be se-
riously burned.


Steam from an overheated engine can
cause serious burns and can occur just
by opening the engine hood. Stay away
from the engine if you see or hear steam
coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until it has
cooled down.
iExcessive coolant temperature trigger
a warning in the multifunction display.

Trip odometer
Make sure you are viewing the trip
odometer and main odometer
(page 109) in the multifunction dis-
play.

If it is not displayed, press button è
or ÿ on the multifunction steering
wheel (
page 110) repeatedly until
the trip odometer appears.

Press and hold the reset button on the
instrument cluster (
page 22) until
the trip odometer is reset.
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.
Outside temperature indicator
The outside temperature is displayed in
the instrument cluster (
page 22). For in-
formation how to select the unit of the dis-
played temperature, i.e. degrees Celsius
(°C) or degrees Fahrenheit (°F) see “Se-
lecting temperature display mode”
(
page 123).
!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.

108 Controls in detailInstrument clusterThe 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.
