Coolant temperature indicatorDuring severe operating conditions, e.g.
stop-and-go traffic, the coolant tempera-
ture may rise close to 120°C.
The engine should not be operated with
the coolant temperature above 120°C. Do-
ing so may cause serious engine damage
which is not covered by the
Mercedes-Benz Limited Warranty.
Trip odometer
Make sure you are viewing the trip odome-
ter display (
page 129).

page 126) until

notes excessive engine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
CLK 55 AMG

not have a red marking denoting excessive
engine speed
To help protect the engine, the fuel supply
is interrupted if the engine is operated at
an excessive engine speed.
Warning!
G


Driving when your engine is overheated
can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously
burned.


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.iExcessive coolant temperature triggers
a warning in the multifunction display
(page 329) and the red coolant warn-
ing lamp in the instrument cluster
comes on (
page 315).
!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.

128 Controls in detailInstrument clusterOutside temperature indicator
The outside temperature is displayed in
the multifunction display (
page 22). For
information on how to select the unit of the
displayed temperature, i.e. degrees Cel-
sius (°C) or degrees Fahrenheit (°F), see
“Selecting temperature display mode”
(
page 142)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.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.

A driver’s attention to the road and traffic
must always be his /her primary focus when
driving.
For your safety and the safety of others, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 13.5 m) every second.
