Outside Temperature Indicator
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 comparison to a
thermometer placed next to the sensor,
not by comparison to external displays
(e.g. bank signs etc.).
Adaptation to ambient temperature takes
place in steps and depends on the
prevailing driving conditions (stop-and-
go or moderate, constant driving) and
amount of temperature change.
Warning!
The outside temperature indicator is
not designed to serve as an Ice-
Warning Device and is therefore un-
suitable for that purpose. Indicated
temperatures just above the freezing
point do not guarantee that the road
surface is free of ice.
Coolant Temperature Gauge
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the
coolant in the pressurized cooling
system of your vehicle is approx.
266°F (130°C).
During severe operating conditions and
stop-and-go city traffic, the coolant
temperature may rise close to the red
marking.
The engine should not be operated with
the coolant temperature in the red zone.
Doing so may cause serious engine
damage which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
•
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 seriously 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 cools down.
