The coolant temperature gauge is on the
left side in the instrument cluster
(page 24).During severe operating conditions, e.g.
stop-and-go traffic, the coolant tempera-
ture 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.
Driving when your engine is badly
overheated can cause some fluids which
may have leaked into the engine
compartment to catch fire. You could be
Steam from an overheated engine can
cause serious burns and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.

Outside temperature indicator
!Avoid driving at excessive engine
speeds, as it may result in serious
engine damage that is not covered by
the Mercedes-Benz Limited Warranty.
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.

122 Controls in detailInstrument clusterThe outside temperature is indicated in the
multifunction display (
page 123). For
information on how to select the unit of the
indicated temperature, i.e. degrees
Celsius (°C) or degrees Fahrenheit (°F),
see “Selecting temperature display mode”
page 137).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

For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
