Engine Oil Pressure Gauge
The oil pressure at idle speed may drop
if the engine is at operating
temperature. This will not jeopardize
the engine's operational reliability.
Pressure must, however, rise
immediately upon acceleration.
Note:
If the oil pressure gauge needle drops
to "0" with the engine running, then
damage to the engine may occur with
continued operation. Turn off engine
immediately and contact an authorized
Mercedes-Benz dealer. Do not operate
the car until the condition is repaired.
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 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 and there is no
loss in engine oil pressure, 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 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 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.
Fuel Consumption Gauge
While driving, current fuel
consumption is indicated in miles per
gallon (mpg), or in Canada liters per
100 kilometers (1/100 km).
With the engine switched off, the
needle reads "0".
Due to system design, minimum
consumption is indicated at engine
idle speed.
Fuel Reserve Warning Lamps
With the key in steering lock position
2, the fuel reserve warning lamps
come on and should go out when the
engine is running.
If the warning lamps do not go out
after starting the engine or if they
come on while driving, it indicates
that the fuel level is down to the
reserve quantity of approx. 3.3 gal
(12.5 liters).
