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.
Tachometer
Red marking on tachometer:
Excessive engine speed.
Avoid this engine speed, as it may
result in engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
For engine protection, the fuel supply
is interrupted if the engine is operated
within the red marking.
Coolant Temperature Gauge
If the antifreeze mixture is effective to
- 30°C (- 22°F), the boiling point of the
coolant in the pressurized cooling
system of your vehicle is approx.
130°C (266 °F).
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.
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.
Turn off the engine and get out of
the car until it cools down.
• 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 and do
not stand near the car until it
cools down.
