Crash Course in 4WD
 

Hi all,

I recently got my Blazer, a 2002 LS 4WD. It's the first time I have ever owned a 4WD. So far, it's been confined to sealed roads, but next week I'm off camping with mates, and this will involve a little bit (40km or so) of dodgy dirt/sand tracks.

This leads me to a few quick (hopefully) questions:

When I leave a sealed road for a track, should I change from 2WD to Auto, or 2WD to 4WD-Hi?

When would I use 4wd-Lo?

On this particular trip I am fairly certain that I won't encounter anything that I wouldn't of taken my old '91 Toyota Corolla thru (granted, I did thrash that car a bit!), but I thought it was a good time to ask these questions!

If its just like a dirt road you can probably just leave it in 2wd. When stuff starts to look hairy you can put it into 4wd. 4low on a stock truck really isn't needed unless you're climbing or going down steep hills.

If you run into trouble, which you shouldn't cuz I have no trouble in 2wd in snow and ice put it in 3rd gear and 4hi. Doubt you'll need it even once though. My grandpa's camp is loose gravel and dirt and I got through in 2wd even spinning my tires on purpose
