The button to disable VSA is on the dash next to the sunroof switch. When VSA is disabled, the /!\ light glows on the instrument panel. If you enjoy driving at the limit, you will find that the car handles very predictably and comfortably with VSA disabled. It neither oversteers nor understeers excessively; it's pretty neutral.

I was always a little hesitant to do it before because I didn't know how it would exactly change the handling. I'll test it out though. Well, at least other owners have found the A pillar blind spot to be troublesome. Glad to hear you didn't drive over the guy though!

On the TSX, the traction-control system is called "Vehicle Stability Assist" (VSA). So, TCS and VSA are just two different acronyms for the same thing. VSA employs both braking and throttle control to maintain traction and stability. If the system is on, you cannot spin the tires. VSA will reduce throttle and apply brakes as necessary. Of course, in hard cornering, it will also brake the appropriate wheels to prevent oversteer. |

Replying to: xplorx4 (Jun 01, 2005 7:47 am) Well, not exactly. Stability control adds inputs from the yaw and steering angle sensors to selectively brake one wheel to correct an oversteer or understeer condition. TCS just looks at wheel slip and brakes the slipping wheel or reduces throttle input until traction is regained. The reason one switch disables them both is that they share solenoids in the ABS modulator. |

Replying to: lmacmil (Jun 01, 2005 6:23 pm) Here's another thing, but correct me if I'm wrong... the VSA on the TSX is the same setup as on the RL and I would assume the TL has the same also. The VSA on the RL allots 60% of power to the front wheels and 40% to the back, but when cornering, the VSA can transfer up to 100% of power to the outside wheels. I was always under the impression that since its the same system on all the cars, that this is what it did. Similar to a limited-slip diff.

Thanks for clarifying the differences between the features. I was aware that technically there is a difference between TCS and VSA, I just didn't provide the details. Though the two systems do different things (as you mentioned above) I believe flicmod was under the impression (previously) that TCS cannot be disabled, but VSA can. I guess my main point was that on the TSX, both VSA and TCS are disabled/enabled when you press the "VSA OFF" button. So that's why I called them "the same thing."
