Mercedes-Benz 300 SD-TURBO DIESEL 1983 Owner's Manual page 47

Hot Engine
Turn key in steering lock clockwise to
the stop and start engine immediately
without depressing the accelerator.
Release the key as soon as the
engine is firing regularly.
Turning off
Turn key in steering lock to position
" 0" and remove only when the vehicle
has stopped.
Should the engine continue to oper­
ate with the key in steering lock
position " 0", refer to page 63.
With very high coolant temperatures
(e.g. after driving on mountain
passes), do not shut down the engine
immediately but allow to run at slightly
increased idle speed foranother 1-2
minutes approximately.
Notes
Due to the installed starter non-re­
peat unit, the key in the steering lock
must be returned to " 0" position
before making a new starting attempt.
Observe the oil pressure gauge
immediately after starting. In a very
cold engine the oil pressure will only
rise slowly, some time after the
Starting and Turning off the Engine
engine has started. Do not speed up
the engine before pressure is regis­
tered on the pressure gauge.
The charge indicator lamp must go
out as soon as the engine has started.
If the preglow indicator fails to light
up, the preglow system is defective
and should be repaired at a
MERCEDES-BENZ service station at
the earliest possible date.
In areas where temperatures fre­
quently drop below - 1 8 ° C/0° F, we
recommend to have a blockheater
installed. Every MERCEDES-BENZ
service station will readily advise you
on this subject.
