I just keep the PDF on my phone, with a direct link to it on one of the "home screens". That way it's always with you, is searchable, etc. Paper has been steadily moving out of the role of information carrier (but still holding its own pretty well in other fields, like packaging or personal hygiene ).
Thanks. Since I did not see the manual for SI coupe, I downloaded the one for the regular coupe.

I see only SI sedan, not SI coupe. I guess SI sedan is good enough.
