What is the purpose of the switch on my 1989 Jeep cherokee 4x4 that says power/comfort for the transmission? ?

Q: When should I have it switched on comfort and when should I have it switched to power? I have left it off (not using either as I drive in the city mostly) Should I have it on comfort while daily driving or just on easy parts of the trail? Also this is my first 4x4 how do I get it into 4 wheel drive? While in neutral or while in park? Can I do it while driving? Thanks to all that can help so I dont drop my transmission :) Im a broke college guy and cant afford that!

A: The power/comfort switch changes the shift points in your transmission. It also changes how hard it shifts. Some people, very few, have noticed a slight increase in fuel economy with the power switch on, but that may be due to driver input more than anything else. My '91 had it as well and I kept it in power all the time. It drove better. Do it while stopped or gently rolling. You can do it in drive as long as you are creeping along. Sometimes though with age you'll find you have to do it either stopped and in neutral or rolling, just because of normal wear on dated vehicles.
