Charge Indicator Lamp - Mercedes-Benz Light Truck ML 320 Operator's Manual

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 fault which
must be repaired at an authorized
Mercedes-Benz light truck dealer
immediately.
If the charge indicator lamp comes on
while the engine is running, this 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 lamp
illuminated. Doing so could result in
serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Low Engine Oil Level Warning
Lamp
With the key in steering lock position
2, the oil level warning lamp comes on
and should go out 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 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
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 or via the oil level indicator
in the odometer display field, for
example during a fuel stop, or before
a long trip (see Index).
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.
