Low Engine Coolant Level
Warning Lamp
With the key in steering lock position
2, the warning lamp comes on and goes
out when the engine is running.
If the warning lamp does not go out
after starting the engine, or if it comes
on while driving, then the coolant level
has dropped below the required 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 Index.
The low engine coolant level warning
light should not be ignored. Extended
driving with the light illuminated may
cause serious engine damage not
covered by the Mercedes-Benz
Limited Warranty.
In cases of major or frequent minor
coolant loss, have the cooling system
checked at your authorized Mercedes-
Benz dealer as soon as possible.
Note:
Do not drive without coolant in the
cooling system. The engine will
overheat causing major engine damage.
Monitor the coolant temperature gauge
while driving.
Warning!
Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene
glycol which may burn if it comes
into contact with hot engine parts.
You can be seriously burned.
Low Windshield and Headlamp
Washer System Fluid Level
Warning Lamp
With the key in steering lock position
2, the warning lamp comes on and
goes out when the engine is running.
If the warning lamp comes on with the
engine running, the level of the
reservoir has dropped to approx. 1 /
4
of
the total volume. The reservoir should
be refilled with MB Windshield
Washer Concentrate "S" and water (or
commercially available premixed
windshield washer solvent/antifreeze,
depending on ambient temperature -
see Index) at the next opportunity. The
reservoir for the windshield and
headlamp washer system is located in
the engine compartment next to the
radiator.
The fluid level can be checked visually
at the sight glass located next to the
reservoir filler cap
