Low Engine Coolant Level W arning
Lamp
The warning 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
required level. If no leaks are notice­
able and the engine tem perature does
not increase, continue to drive to the
nearest service station and have
coolant added to the coolant system
(see page 73).
Low W indshield and Headlamp
W asher Fluid Level W arning Lamp
The warning lamp comes on with the
key in steering lock position 2 and
should go out when the engine is
running.
If the warning lamp comes on with the
engine running, the level of the
reservoir has dropped to 1A of the total
volume. The reservoir should be
refilled with MB W indshield W asher
Concentrate “S” and water (or com ­
mercially available premixed w ind­
shield washer solvent/antifreeze,
depending on ambient tem perature) at
the next opportunity. The reservoir for
the windshield and headlamp washer
systems is located in the engine
com partm ent (see page 116).
Outside Tem perature Indicator
The tem perature 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 therm om eter 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.
W arning!
The outside tem perature indicator
is not designed to serve as an
Ice-W arning-Device and is there­
fore unsuitable for that purpose.
Indicated tem peratures just above
freezing point do not guarantee
that the road surface is free of ice.
