Fun things you learn from the manual
I believe that one issue many people (including myself) have is simply not following instructions. So to follow instructions I looked at the manual cover to cover now two weeks into buying the car. Here are two things that were fun to find out:
1. For the 1st 1k miles (for non AMG cars) shift gently and do not run tachometer above 2/3.
2. Do not wash in brushless car wash because of the harsh chemicals (I guess soft brush wash is the way to go)




Interesting one I found is that you have to place HVAC on re-circulate before using an automatic car wash. Problem is that if you use the conveyor type, you have to park your car and cut it off. This disengages the re-circulator. Then an attendant drives it to the conveyor. Even if you tell him and show him, will he do it? Will the same guy drive it that vacumed it?

There is much information in the manuals...and there is much information that isn't in the manuals
e.g. how do you see your instruments if you are driving at dusk? which is the correct tire pressure label to follow?




Apparently it has something to do with the force of water from overhead jets may force water to go into the cabin filter, even if A/C is off.
I guess recirc closes a door or something that keeps water out.
