For some reason Volvo decided to leave off the switch on 99 00 XC's and R's but you are correct, it IS hot and it WILL work if you install the switch.
A few of us just did with our R's.
When pushed it will DISconnect the tracs from the AWD system
You would turn it OFF if you were stuck in the snow and the other time would be if you're "drifting", something you probably don't have enough power to do in an XC

Thanks, seems worth it to get one if it could help get unstuck. I see some today on Ebay for $1. But I really don't understand how turning TRACS off could help getting unstuck in snow since that is what the TRACS system is designed to do when it is ON. Confused.
2000 V70XC SE - 174k miles Total repairs over past 7 years: $1,060 ($151/year) but needs a new angle gear. 28-31mpg highway; 17-21 mpg city - accurately measured
TRACS was a promise, not an actual functional feature. In my opinion. I believe the brakes were not programmed to be strong enough upon trigger of the TRACS system.
I've always been able to spin the tires on wet pavement or snow with application of throttle. I can hear the ABS system trying to slow the wheels, but it's simply a matter of the brakes not being applied strongly enough by the system.
