Which do you drive in more often and why?

I've been in Auto since Saturday - it's been snowy and crappy here on the East Coast. But, I can't help but wonder if I *really* need to be in Auto, and will I get better gas mileage from 2WD?

i've always kept it in auto. I've switched back and forth and actually get better gas mileage in auto than 2wd

Auto is normally in 2WD until slip is detected on the rear wheels, then an electronic clutch engages on the transaxle locking it into 4HI.

This isn't the normal AWD but an auto 4WD as Honda also uses.

Page 5-20 of 2005 Nissan Armada Owner's Manual:

With the switch set to the AUTO position,
distribution of torque to the front and rear
wheels changes automatically, depending
on road conditions encountered [ratio; 0 :
100 (2WD) → 50 : 50 (4WD)]. This results
in improved driving stability.


It's not recommended to drive over 62 mph in 4HI. Since there is no warning in the manual when in the AUTO mode, it must automatically lock out 4HI when over 62 mph.

Have a good one.

I leave mine in Auto. Not sure what a difference it makes on gas mileage.
