I believe the A/M button allows you to choose between automatic and manual mode on the transmission. In M mode you have to do the shifting by yourself and while in that mode the transmission tends to stay in gear a little bit longer than normal.
quick question i would only use manual if i was towing or maby winter conditions
You can use manual for the both mentioned above but it also acts as a "sport" mode and allows you to choose the gear. It's supposed to give you the feeling of a manual but it's more useful in winter conditions than anything else.
