1. Debra T Says: i just don't understand what that means. is that an option to have it the 4x4 off? cause i know jeeps are all 4x4 which sucks to have it on all the time

2. GordonFlash Says: It means that you have the choice of driving it in:

2WD: Normal driving

4 high or 4Hi:
You would select 4WD high on snow and for easy to moderate off-road (dirt roads, easy trails). You would select it to have better use of traction (better than 2WD) to get going and to maintain forward movement with a reduced risk of slipping and spinning wheels.The added lateral stability of 4WD makes it less likely to slip sideways.

Four wheel drive low (4 low or 4Lo).
When "4-low" is selected the wheels create substantially more torque (on a Grand Cherokee its 2.72 times more) than in "4-high" - at the same time the vehicle moves at substantially slower speeds (2.72 times slower than in 4Hi on a Jeep Grand Cherokee).
Important: "4-low" does not create more traction - it creates more torque and that can be detrimental when traction is marginal. Slipping tires are more likely in "4 low" than in "4 high"!
For that reason 4 low is not a good choice for snow or ice - and not a good choice for mud either!

4. Jin Says: Mode selection is a term used when you are able to choose your transmissions formation.

4x4 vehicles are made so that you are able to switch from 4x4 to 4x2 in instances where you are driving on normal conditions and would like to save on fuel consumption. You may also have the option where you are choose from 4x4 low or 4x4 high, these two differentiate with the amount of torque provided to your wheels.

I hope I helped...Jin
