1) Here is the link to the SHIII Community Manual website:

It's a great resource but isn't being updated/maintained anymore and there is a copy available below:

Here is how I use Auto Mode:
I look through the attack scope (F3) then turn to where the target is. I then get the colored arrow (hovering on the target) with type of boat, heading and speed. IF the arrow is green (preferred) or yellow then I'll consider it a valid target - red isn't worth it and will waste fish.
I hit the "lock" button and instantly switch to the TDC screen (F6). At that moment, I normally get a couple lines running from my boat to the target. They tell you how long it would take for the fish to hit the target (You may need to zoom in or out to see all that detail), what the direction is visually on your chart and even show the angle and direction that the fish will need to use hit the target.
NOTE:
IF while on the TDC screen, those same lines disappear then it's either due to a too large of angle (turn the front end of your boat to face the target), or you have a yellow or red locking arrow on target.
The angle should look something like the 2nd image down on the TDC SH3 Community Manual website:

Finally, please understand you can be in full Auto Mode and still not be able to find targets. So, when you get a ship that pops up with course and speed you can use the following two images to help understand how to plot a successful intercept course:
Hope that helps,
