Vehicle Stability Assist (VSA)
The TL is equipped with 4-channel VSA that helps the driver retain control of the car in the event the vehicle reaches its dynamic traction limits, for example through aggressive cornering, encountering ice or dirt on the road, or entering a decreasing-radius corner too fast.
In the event of understeer (where the front tires lose grip), the system applies the inside front and rear brakes to increase yaw (vehicle "rotation"), slowing the vehicle and enabling it to complete the turn. Engine torque may also be reduced by coordination of the Drive-by-Wire Throttle System and Engine Controller.
The 4-channel system controls all four brakes independently. In the event of oversteer (where the rear tires lose grip), the system applies the outside front and rear brakes to decrease yaw, slowing the vehicle and enabling it to stay on its intended path.
An indicator light on the instrument panel alerts the driver whenever the VSA system is actively enhancing the vehicle's stability.
The traction control component of VSA uses sensors that monitor each of the wheels and a computer-controlled modulation of engine power and front brakes to help prevent wheel spin when starting out or accelerating. If the sensors detect wheel spin, traction control reduces engine power and applies brake force to the affected wheels. This helps the TL maintain traction during acceleration and helps the driver retain steering control, even when accelerating on slippery surfaces.
A cockpit switch is provided to disable the vehicle stability and traction control aspects of the system while leaving the ABS system fully functional.

I've seen the VSA come on a few times. Get a little wild on a wet road and it will go off. However, it only comes on for the exact seconds it's being used, it doesn't stay on for any buffered time or anything... it might flash for 1/8 sec here and there and you would never notice.

Good idea. I may try that around here.
This has bee some damn good info. Thanks everybody for taking the sime to share.
