Starting and Turning off the Engine
Engage parking brake and move the
gear selector lever in either “ P” or
“ N” position before starting the
engine.
Cold Engine
Turn key to steering lock position 2.
Charge indicator and preglow indica­
tor lamp should come on. The pre­
glow process starts. When the pre­
glow indicator goes out, the engine is
ready for starting.
Ambient Temperature
above 0° C (+ 3 2 ° F):
Turn key in steering lock clockwise to
the stop. Do not depress accelerator.
Release key only when the engine is
firing regularly.
Ambient Temperature
below 0° C ( + 32° F):
Depress accelerator to the floor. Turn
key in steering lock clockwise to the
stop. Release key only when the
engine is firing regularly and back off
accelerator slowly.
Do not interrupt the starting process.
If the engine is very cold it is possible
that it will fail to start on subsequent
attempts.
Hot Engine
Turn key in steering lock clockwise to
the stop and start engine immediately
without depressing the accelerator.
Turning off
Turn the key to steering lock posi­
tion 0 and remove only when the vehi­
cle has stopped.
Should the engine continue to oper­
ate with the key in steering lock posi­
tion 0, refer to page 68.
If the coolant temperature is very high
(e.g. after hard driving on mountain
roads), do not shut off the engine
immediately, allow it to run for
1 —2 minutes at increased idle speed.
Important!
Due to the installed starter non­
repeat unit, the key must be returned
to steering lock position 0 before a
new starting attempt is made.
Observe the oil pressure gauge
immediately after starting the engine.
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
registered on the pressure gauge.
The battery charge indicator lamp
should go out as soon as the engine
has started.
If the preglow indicator lamp fails to
light up, the preglow system is defec­
tive and should be repaired at your
authorized MERCEDES-BENZ dealer
at the earliest possible date.
The engine is equipped with a block
heater to provide reliable starting at
temperatures below —18° C (0° F).
