Engine Oil Pressure Gauge; Low Engine Oil Level Warning Lamp; Engine Oil Consumption; Fuel Consumption Gauge - Mercedes-Benz 320 SE Operator's Manual

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).
The warning lamp blinks when the fuel
cap is not closed, or the fuel system has
a leak.
