FYI, there is a large blind spot when driving this car and I found round stick-on mirrors at NAPA that I attached to the sideview mirrors and they seem to be working quite well.
I used to use the "little round mirrors". But then I discovered the method Ms. HEMEE described (via a Click-n-Clack article) and tried it. With the "mirror memory" feature of the 300, you can get the mirrors REALLY tweaked most supremely, so that as a car slowly passes you in the left lane, the left headlight disappears from the rearview mirror, and then appears instantly in the left outside mirror, aligned perfectly and seamlessly with the image in the rearview mirror.kcrnmale said:I use the little round mirror on the driver's side mirror too. Once you have one, you'll never drive without one again. It's too small to use on the passenger mirror. I use it to confirm what I already should know looking over my left shoulder behind me.
HEMEEE said:Adjust Mirrors To Eliminate Blind Spots
Most people make the mistake of adjusting the outside mirrors to look directly behind the car. The inside mirror should be adjusted to see directly behind you, but the outside mirrors should expand that field of vision to the left and right of what you can see with only the inside mirror. As a vehicle behind you approaches to pass, it should appear in one of your outside mirrors just before it disappears in your inside mirror. As that other vehicle overtakes you, it should be visible directly in your peripheral vision before it completely disappears from view in the side mirror.
I call this the "Outbound Mirror Setting". I adjust it as described above but I leave a litle overlap with the outside mirors and the rear-view mirror so that I get a little bit of overlap and pick up the vehicle a smidge in both mirrors. Once the vehicle is totally in the rear-view mirror, I know that the lane is clear.
