Since you don't have the manual I'll give a real simple breakdown of each mode. You can stay in 4Hi for moderate offroad conditions and it'll pull you through. 4HiLock should be used when doing anything more complicated and you require more traction, like deep snow, mud, sand, etc. 4LowLock should be used when you're doing low speed and require more traction, BUT you shouldn't take it above 30mph for extended periods.

you should definititely order the manual/user-guide, it has more good info about your H3.... Also, in order to switch between 4HiLock and 4LowLock (center and right button), your vehicle should be shifted to neutral and be either stopped or moving very slow. I always fully stop and shift to N before switching 4HiLock/4LowLock; not 100% sure if not doing so will only prevent 4WD mode switch, or will switch but with possible resulting damage...

the 4hi is the one light that should always be on when driving in normal conditions in order to switch to the other ones you must be stopped and i bieleve in neutral between 4hilock and 4lowlock but whichever you ave on the light for that particular one will remain on.

It will automatically disengage 4low above 20mph.
