Full Time 4 Wheel Drive?

Hello,

I just pulled up my Build Sheet from: How to Get Your Factory Jeep Build Sheet - Jeepsies
It says that my 2007 Commander Limited has Quadra-Trac II Full-Time,Active 4WD. :crying:
I thought when its not manually put into 4 wheel drive its in 2 wheel drive. Is this not the case or am I reading this wrong?
@BLEE8282 ;

4 x 4 Commanders - regardless of which 4WD system you have, are in 4-HI all the time - unless you manually drop down into 4-LOW, they are not capable of switching from 4WD to 2WD.

Quadra-Trac II and Quadra-Drive II both are equipped with the NV245 two-speed transfer case which gives you the capability to shift down into 4-LOW using the silver T-Handle jeep5253 was talking about - which you can see in the photo below circled in blue;

Do not use that lever unless you are on a slippery surface and going less than 20mph! Using it on dry pavement at regular driving speeds can damage the system.
Ideally, you want to be stopped - and in neutral, when switching into 4-LOW.

Being on a slippery surface is not as important as what I just mentioned - but it is recommended.

You can switch into 4-LOW on a hard surface without causing any damage to your 4WD system, as long as you are gentle & deliberate when you accelerate.
 
Mine will not go into 4L unless you are stopped. If you can move yours rolling, it's broke.
I've never tried.

I've always been stopped when shifting into 4-LOW.
