If you start to slide as in turning a corner, you will see the dash light flash and a beeping sound. Basely it applies brake to the wheel which is spinning, excessively. I drive in slippery conditions often and the system diffidently does its job if your sliding sideways. Will assist if only one wheel starts to spin, also.
If your in conditions, as in stuck, which will cause the front wheels to spin, quickly turn the unit OFF. The wheel spinning will get some brake applied, when the other starts spinning again brake is applied. The application between the two wheels will lock up the wheels, the brakes don't release themselves quick enough to counter this condition.
My vehicle was relatively new I got stuck is some snow, because I didn't turn the unit off, I made my condition much worst. Especially if you need to rock the vehicle back and forth it will lock up wheels to where the engine wont even be able to turn them. Finally got out the manual and figured out what was going on.

Backwoods----what is the build date of your Sienna? Mine is April 2007---wondering if there was a programming change somewhere in the model year.

I wonder if you are confusing VSC, Stability Control, with TC..??
Tc is used to assure that the loss of traction on the front wheels will not be of extended duration, so much so that loss of directional control will result. If you inadvertently use/apply too much engine torque for roadbed conditions then TC will INSTANTLY react by dethrottling the engine and applying braking, HAMMERING the brakes on the pair of wheels wherein one is slipping.
VSC, on the other hand, might be delayed until you get up to some minimum speed wherein YAWING can be more of a threat and/or more easily detected.

Should I ever be able to smoke the tires on dry pavement with the TC on?

If your on dry pavement, it may not activate. I suspect there needs to be a large differential in wheel speed to activate, other wise in a sharp turn it would come on. Unless one wheel breaks free, as on very slippery conditions (ice snow) it may not activate.
Mine is a 2004, doubtful there is little difference in programing between all the years.
