cluster displayPractical hints Car care Index Low engine coolant level warning lamp
With the key in steering lock position 2, the
warning lamp comes on. It should go 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
page 198.
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 Center 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.Low windshield and headlamp washer system fluid
level warning lamp
With the key in steering lock position 2, the
warning lamp comes on. It should go 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, the level of the
reservoir has dropped to approximately 1/3 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 page 199) at the next opportunity. The reservoir for
the windshield and headlamp washer systems is located
in the engine compartment.
Wa r n i n g !
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 engine oil level warning lamp
With the key in steering lock position 2, the
oil level warning lamp comes on. It should
go out immediately when the engine is
running.
If the warning lamp does not go out after starting the
engine, or comes on with the engine running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning lamp will first come on
intermittently and then stay on if the oil level drops
further.
If no leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
The low engine oil level warning light should not be
ignored. Extended driving with the light illuminated
could result in serious engine damage that is not
covered by the Mercedes-Benz Limited Warranty.
In addition to the warning lamp, the engine oil level
should be periodically checked with the dipstick, for
example during a fuel stop, or before a long trip, see
page 197.Charge indicator lamp
Should the charge indicator lamp fail to
come on prior to starting when the key is in
steering lock position 2 or should it fail to go
out after starting or during operation, this indicates a
malfunction which must be repaired immediately at an
authorized Mercedes-Benz Center.
If the charge indicator lamp comes on, or a loss of power
steering assistance is noticeable while the engine is
running, this may indicate that one of the two poly-V-
belts has broken. Should this condition occur, the poly-
V-belt must be replaced before continuing to operate the
vehicle. Otherwise, the engine may overheat due to an
inoperative water pump which may result in damage to
the engine.
Do not continue to drive the vehicle with the charge
indicator lamp illuminated. Doing so could result in
serious engine damage that is not covered by the
Mercedes-Benz Limited Warranty.

With the key in steering lock position 2, an
indicator lamp comes on. It should go 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, this lamp
indicates a failure in the parking lamp, taillamp, stop
lamp, or low beam headlamp.
If an exterior lamp fails, the indicator lamp will come on
only when that lamp is switched on.
If a brake lamp fails, the lamp failure indicator will
come on when applying the brake and stays on until the
engine is turned off.
Note:
If additional lighting equipment is installed (e.g.
auxiliary headlamps etc.) be certain to connect into the
fuse before the failure indicator monitoring unit in
order to avoid damaging the system.Additional function indicator lamps
