Proper diesel starting procedure?

[86560SEL]

Did a search - no luck on this question.

What is the proper starting procedure when starting a older (1980s) Mercedes diesel as far as the accelerator goes? I know that you have to let the glow plug indicator lamp on the dash board go out before you crank it, but what about the accelerator? They lady I bought my 190D from said you are supposed to depress the pedal down 1/2 way when cranking, but I was assuming since it was fuel injected that it would be like a gasoline engine car and you did not have to touch the pedal at all. Also, my glow plug light goes out after about 4-5 seconds when its in the 80s outside... is that normal? I am assuming that colder temperatures require longer intervals? My car starts very quickly though if I start it as soon as the light goes out, but wow, she likes to smoke until she warms up. Maybe its a diesel thing?

I did not see anything in the owners manual about it, unless I overlooked it. Please bear with me... this is my first running diesel car I have ever owned and still learning. My last Mercedes diesel (74' 240D) was a pile of crap and never really did anything with it. Thanks for any insight.
