I think all my manuals are about 2 inches thick. The dealer had to change to a larger black plastic thing because the older thinner ones were ripping. I'm losing that much weight to compensate their existence in the glove box. I realize though that reading through something isn't enough. You may have to read it several times. At least they seem to have good indexes. I don't like reading them... I like asking questions here.
In the liftback, it was just a cover for the battery, no tray. Maybe it's something used in other countries.
