    ok, so we're in winter now and we could get some real snow anytime soon. i thought i'd read up my manual on how to use that darn "car with a squiggly line behind it" button (TRAC).

    vsc, trac, auto-lsd...i'm so confused.

    1) what does each one really do?
    2) what is on and what is off when no lights are on?
    3) what is on and what is off when i push the magic button?
    4) what is on and what is off when i hold the button?

    yes i have read the manual, but i just don't get it. :mad:

    thanks for any dumbed down version you can give me

    LSD- the Limited slip differential uses the vsc sensors to monitor when one wheel spins faster than the other. EX when the left wheel spins faster than the right the vsc will apply brakes to the left wheel, transfering power to the right.

    TRAC is LSD on front and rear. Its a term for the LSD combined with the vsc.

    Vsc is the traction control

    no

    When you initially start the engine in 2wd the lsd is off and vsc is on. press the vsc button squigle car and the lsd is on vsc is off.

    4hi TRAC is activated. press and hold the button and lsd and vsc turns off

    4lo TRAC is off truck is open-open unless you have a locker. If you have a 4x4 with TRAC or TRD Sport with trac. 4lo trac is disabled (unless you mod it)

    VSC is more than just traction control, it's also stabilty control as well.

    The best way to learn is to just test the modes out. Learn how to engage each feature and wait for some snow!

    Thanks guys! It was bigger, but I shortened it so it could be my signature... and is... for now.

    Yes, play time... use your truck and have fun! TRAC in H4 and A-TRAC in L4 does it all. The RR Locker perhaps to get you out if you do get stuck. It worked for me... I didn't bury the truck a second time to see if just A-TRAC would get me out.

    Snow? Not just snow, but SAND... desert or beach sand, the truck rocked in Baja last weekend! No air deflation of tires needed with TRAC in H4. Normal open differentials in 4WD (my 2005 and 2001 Tacomas) would require lowering the pressure to 15 psi to drive on the soft sand. That is how I stuck my new truck, by de-activating TRAC (pushing the VSC off button for 5 seconds while stopped).

    You are welcome! I got my Tacoma with all these choices last month, and I needed to put it down 'on paper' to understand all the choices clearly. H4 in normal (TRAC on) mode will impress you compared to the previous Tacomas with open differentials. L4 with A-TRAC will also impress you if you need to crawl up a cliff! Yoytoda, Isthatahemi and others here were helpful when I began asking about the systems, because the owners manual sure didn't answer my questions.

    Have fun with your truck!

    yes, i'm having fun already. i haven't tested out 4L very much, but when i have, it beeps at me constantly while it's selected. is this normal? or is the beeping mean that there is something wrong?

    It means you're not in 4 Lo. You have to stop the truck, put it in neutral, switch to 4 Lo, and then put it back in Drive.

    No problem. I had to read the manual to get mine in 4Lo, but after I did, it stopped beeping at me.

    Exactly... On your sun visor are the instructions for L4, as well!

    don't forget ...if you have a manual transmission you have to push the clutch in while you turn the knob to get it to go into 4lo
