4 wheel drive

4 wheel drive is dangerous because it allows you to START rather quickly especially vs a rear wheel drive. The dangerous part is you cannot STOP any faster than any other vehicle.
Driving in snow is all about understanding limitations.
I once drove a Ford Pinto with no snow tires from Niagara Falls to New Hampshire with snow on the road from Syracuse. I had to go up a mountain east of Keene. On the way up I passed a couple of 4WD Jeeps off the road. At the top I had to stop and wait for the snow plow, but I made it all the way up without stopping. YMMV

DO not use 4wd on dry pavement. do not. its for
ice, snow,or dirt.
if you do that and make a turn , it winds up the driveline. damage.
put in the dirt, at side of road, and get it out of 4wd.
read the manual on part time 4wd, its not AWD and has no center diferental to drive on hard pavement.

RTM then RTM again......

Some vehicle have a spacefic routine you have to go threw to go from 4 to 2. Try it in neutral. or after you shift back into 2 drive in reverse for a bit till it pops back into 2.

Hi

Full time 4 wheel drive should be used on rugged and difficult to drive on terrain, this could include adverse weather such as deep snow, mudslides, sand dunes etc.

Part time would be used on terrain that is irregular where some parts of a track may be road and other parts rocky, mountainous regions combined with any of the above weather conditions. The 4 wheel drive should not be used for normal driving as it will only over time damage the gearbox, the 4 wheel system is not designed for speed but purely for grip and stability.

Hope this helps

With the Jeep in park, move the left shifter to 4 wheel drive. Proceed to put right shifter into drive, proceed to drive. Only use 4wheel drive when neccessary...ie...snow, mud, use 4 wheel lo in steep incline or when really bogged down.

Hope this helps

Correct

if it grinds then shut the truck off and then switch to two wheel drive

You can find information about this and other subjects in here:
- Jeep 4x4 Basic
- Jeep WJ Grand Cherokee (1999-2004) Owners Manual
- Jeep WJ Grand Cherokee (WJ Jeeps)

Also, in here you can read the WJ 2000 Service & Repair Manual

I hope help you whit this (rated this help) Good luck.

Congratualtions for wanting to get the facory recomended way to operate your car. It should be required reading for all car owners.

For the manual: I would first try a junk yard, if no luck, type factory owners manuals into google and you will have many choices

For the Key fob, I assume you mean a cherokee original type key. I would think these are available to lock smiths if you can convince them to order it. for you
Good luck

That is up to your preference in my opinion. 4 wheel may give you a little more traction, but it can also lead you into a false sense of security. If heavy snow, and you need to get through it, you can only go as fast as the guy ahead of you anyway right? Up here in Ontario Canada, I passed by many a 4 wheel drive in the ditch, because they assumed they would have a better chance on icy roads than me, with 2 wheel drive. Remember this, no matter what you decide, you may be able to go a little faster in 4 wheel, compared to 2 wheel, but when you have to hit the brakes, or go into a spin, 2 wheel or 4 wheel drive, your not going to be able to stop it any faster. Your going to use more gas in 4 wheel too. Yes there will be times when you need to use it, but like I said, when it goes sideways or you have to lock up the brakes, because you were pushing the envelope too much,? At least with 2 wheel, you feel the back end break loose, to warn you how slippery it is, and you may not feel that soon enough, with 4 wheel. Just my opinion, but maybe some 4 wheelers have a different opinion. It's just like the experts from the skid school said up here about mandatory snow tires being talked about. If putting snow tires on your car is going to make you drive a little faster, your defeating the purpose.
