I currently park on a slope everyday at night and in the morning I just let it roll a bit and start it by putting it into the second gear. I started doing this when I had a weak battery. And now even with a new battery I sometimes do it out of habit.
Will this cause any kind of damage or faults to the car?
And I have noticed that I can even start my car even while keeping the key only at the unlock steering position and need not put it in the ignition on position. I started starting it this way because it doesn't give a sudden jerk feeling while putting into the second gear while moving, but starts up the car anyway and then I key to ignition position and continue driving.
Why doesn't the car jerk in this method compared to normal way with the key all the way turned in?
Note: My Car is an old 2005 Peugeot 206. Location Germany if that matters.
Edit: Let me rephrase the second question.
I have noticed that I need not keep the key in Position ON to kick start the engine. Even with position ACC, the engine starts up but with less lurching, while keeping the key in ON position turns the engine with a hard lurch.
Could anyone explain why there is a difference in behaviour during the kick start based on the ignition key position.
