[Centerfire]

OK I read the manual again.. I swear the more I read it the stupider I get. This is a 2 parter.

1. Ac/Heat controls.. Ok if I put it on auto the display indicates on my feet and body.. If I want it on defrost and etc. you can not use "Auto"??? Will auto work on defrost or do I put on defrost then later cahnge it back to auto?

2. ALL THE DAMN TRANSAXLE BUTTONS.
I don't do any heavy off road. this is really concerned with Snow.. in Indy we can get some snow.. My driveway to apprx 900 ft long and ends up with 3-4 ft drifts at times.

4Hi is for normal driving I got that one.
4Hi Lock. Is this for driving under say 60 -65 with snow on the road ?
4Lo and the other two buttons when or what the heck are they for?

Ok pros. Help me
