Pardon my ignorance if I'm completely out to lunch, but this is the first 4x4 vehicle I've owned and it has the part-time and full-time option and I'm just curious as to what they mean and what should I keep it on to obtain best traction while driving on slippery/icy roads. I would also like to know what the 4Lo means and if keeping it in 4x4 mode will affect my fuel efficiency. Thank you.

I'm not totally familiar with your Jeep but Heres my thought.
Normal highway dry .. part-time
Slippy highway....full-time
Slippy in your driveway going slow...4lo
Best deal is read your owner manuel but if like me I bought a used 2010 and it still didn't have one in it ! Took me forever to set the darn clock !

 

acutally part-time locks front and rear axles while fulltime maintains a open center diff.

so normal condition 4x4 full time . when you think your going to get stuck then its 4x4 partime and if you need serious pulling power at slow speed then 4x4 low

 

Darn...I guess I got that **** backwards ! LOL

 

Its all good i dont know what kind of jeep the op has but here is a few transfercases and how they operate
