Coolant Temperature Gauge
If the antifreeze mixture is effective to
- 3 0 °C ( - 2 2 °F), the boiling point of
the coolant in the pressurized cooling
system of your vehicle is approx.
130°C (266°F) (see also “ Fuels, Cool­
ants, Lubricants, etc.” ).
During severe operating conditions
and stop-and-go city traffic, the cool­
ant temperature may rise close to the
red marking.
Low Engine Coolant Level Indicator
Lamp
The indicator lamp comes on with the
key in steering lock position 2, and
should go out when the engine is
running.
If it comes on with the engine running,
the coolant has dropped below the re­
quired level. If no leaks are noticeable
and the engine temperature does
not increase, continue to drive to the
nearest service station and have
coolant added to the coolant system
(see page 73).
Fuel Reserve Warning Lamp
The fuel reserve warning lamp should
come on when the key is turned to
steering lock position 2, and should go
out after the engine is running.
If the warning lamp stays on after the
engine starts, or comes on while driv­
ing, it indicates that the fuel level is
down to the reserve quantity of 6.5 I
(1.6 US gal).
Low Windshield and Headlamp
Washer Fluid Level indicator Lamp
The indicator lamp comes on with the
key in steering lock position 2 and
should go out when the engine is
running.
If the indicator lamp comes on with the
engine running, the level of the reser­
voir has dropped 1/3 of the total vol­
ume. The reservoir should be refilled
with MB Windshield Washer Concen­
trate “ S” and water (or commercially
available premixed windshield washer
solvent/antifreeze, depending on am­
bient temperature) at the next opportu­
nity. The reservoir for the windshield
and headlamp washer system is lo­
cated in the engine compartment (see
page 112).
Outside Temperature Indicator
The temperature sensor is located in
the front bumper area. Due to its loca­
tion, the sensor can be affected by
road or engine heat during idling or
slow driving. This means that the ac­
curacy of the displayed temperature
can only be verified by comparison to
a thermometer placed next to the sen­
sor, not by comparison to external dis­
plays (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 there­
fore unsuitable for that purpose.
Indicated temperatures just above
freezing point do not guarantee
that the road surface is free of ice.
