Generally, it's good to at least check the manual. Things like bulb size, fluids, wiper blade sizes... are going to be in there somewhere. It may not always be in a location that is easily found, but it will be there.
Lots of users register just to ask a question to save themselves the 2 minutes it would take to look for the answer. It adds up fast. I find responses to be much more positive to posts that are along the lines of "I tried this and I looked for an answer but I still need some advice..."
To your point, I researched via google, searched the sight, but found no information. Thus, I posted a question. Next time I will be sure to use that as a qualifier to avoid the needless posts. Thanks for the pointer re: the manual. Learn something new every day
