Starting and Turning off the Engine
Ambient Temperature below
0°C / + 32° F:
Depress accelerator completely. Turn
key in steering lock clockwise to the
stop to start the engine. Release key
only when the engine fires regularly
and runs smoothly. Then release the
accelerator slowly.
Do not interrupt the starting process.
In the case of a very cold engine there
arises the danger of the engine failing
to start at another starting attempt.
At ambient temperatures of less than
- 1 8 ° C/0° F, depress accelerator
three times prior to starting.
Hot Engine
Turn key in steering lock clockwise to
the stop and start engine immediately
without depressing the accelerator.
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 fo r another 1-2
minutes approximately.
Notes
Observe the oil pressure gauge
immediately after starting. In a very
cold engine the oil pressure will only
rise slowly, some time after the
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 preglowing system is defec­
tive and should be repaired at a
MERCEDES-BENZ service station at
the earliest possible date.
In areas where temperatures fre­
quently drop below — 18° C/0° F, we
recommend to have a coolant prehea­
ter installed. Every MERCEDES-BENZ
service station will readily advise you
on this subject.
