Sorry for the newbie question but I just purchased an 08' 4x4 tahoe but I've never owned a 4x4 vehicle before. I just wanted to know when am I supposed to use the 4x4 feature other than for snow. When do I use 4x4 Auto, hi, or lo? Is there a speed limit to 4x4 hi? I tried using the 4x4 hi going to Reno this weekend going uphill but didn't notice any differences to 2wd. Someone teach me something new.

Thanks in advance!

First read the Owner's Manual. It has some good info on this. Generally you stay in 2WD on dry, solid surfaces. Use Auto in most slippery surfaces like snow and ice. I only use 4WD Hi if the snow is deep. Otherwise 4WD Hi & Lo are pretty much for offroad.

Search this forum as ZX had a good explanation of this awhile back.

Wilco.

Was the explanation close?

Does this "Autotrac transfer case" feature allow me to drive 4wd on dry pavement?
