Two ways to look at lousy manuals:
@JoeMario, as a lifetime technical writer, the manuals in most new cars nowadays are “generic”. In other words, if you go look at the Nissan Maxima, Altima, etc. manuals - they have gotten so lazy that the difference between the expensive car manual and the lower cost car manual are hard to tell apart.
First of all, the answer is directly related to their perception of taking away liability from them - read ond.d
I still have some of my old manuals from the 70’s. They were detailed, you had most of the information you needed in the manual provided by the manufacturer there was no need to purchase a Haynes or something like that.
They are trying so hard to say nothing - thinking it won’t bring liability on them, by saying so little, they are actually shooting themselves in the foot. But that is corporate bureauacry for you
If you go look at a 2009, 2010, 2011 2012 model years of a Honda Accord, Nissan Maxima, cars like that - their manuals from year to year are virtually the same. They are doing a “save as” and think I didn’t notice? Wrong!
I have many friends in technical writing associations and we laugh, and then we don’t, because when you are under contract to write the manual, you have to do what the contract says - in other words, if I want to make the manual actually useable, the manufacturer won’t let me.
