Coolant Temperature Gauge - Mercedes-Benz 190 E 2.3 1991 Owner's Manual

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).
During severe operating conditions
and stop-and-go city traffic, the cool­
ant temperature may rise close to the
red marking.
The engine should not be operated
with the coolant temperature in the red
zone.

Warning!
• Driving when your engine is
badly overheated can cause
some fluids which may have
leaked into the engine compart­
ment 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.
Low Engine Coolant Level Warning
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 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 77).
