Charge Indicator
When the symbol and message appear
while the engine is running, this
indicates a fault which must be repaired
at an authorized Mercedes-Benz dealer
immediately.
It may indicate that the poly-V-belt has
broken. Should this condition occur,
the poly-V-belt must be replaced before
continuing to operate the vehicle.
Otherwise, the engine will 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 symbol
displayed. Doing so could result in
serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Engine Oil Consumption
Engine oil consumption checks should
only be made after the break-in period.
During the break-in period, higher oil
consumption may be noticed and is
normal. Frequent driving at high engine
speeds results in increased
consumption.
Low Engine Oil Level Warning
When the symbol and message appear
while the engine is running and at
operating temperature, the engine oil
level has dropped to approximately the
minimum mark on the dipstick.
When this occurs, the warning will first
come on intermittently and then stay on
if the oil level drops further.
If no oil 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
should not be ignored. Extended
driving with the symbol displayed
could result in serious engine damage
that is not covered by the Mercedes-
Benz Limited Warranty.
In addition to the warning symbol, the
engine oil level should be periodically
checked with the dipstick or via the
multifunction indicator, for example
during a fuel stop, or before a long trip
(see Index).
Fuel Reserve and Fuel Cap
Placement Warning
When the warning lamp comes on and
the symbol appears after starting the
engine, or if they come on while
driving, it indicates that the fuel level is
down to the reserve quantity of
approximately: 2.1 gal (8 liters).
The warning lamp blinks when the fuel
cap is not closed, or a fuel system leak
has been detected. Retighten cap and
see if lamp goes out.
If the warning lamp continues to blink
after closing the fuel cap correctly,
have the fuel system checked at your
authorized Mercedes-Benz dealer as
soon as possible.
Leaving the engine running and the fuel
cap open can cause the "Check
Engine" lamp to illuminate.
