Hello,
I am considering purchase of a new IS250. My only reluctance is the presence of electronic "Driver Aids".
I detest Stability Control and Traction Control and am forever skeptical of the "Off" button - they often do not completely defeat the systems. The Porsche Cayman for example, will activate the Stability Control System if ABS is engaged, even when in the "Off" position. Does anyone know (for certain) if the Stability Control and Traction Control systems are COMPLETELY defeated when the button is in the "Off" position? If not, do you know the criteria under which those systems will activate when the button is in the "Off" position (i.e. higher threshold, when ABS is activated, etc.)?
Similarly, I do not ever want the Brake Assist system to function. In all honesty, I have never felt such a system in action, but it's presence concerns me nonetheless. My braking inputs are always deliberate; the last thing I want is interference from a computer designed to assist untrained drivers. Does anyone know (for certain) if it's possible to defeat this system?
Finally, if aftermarket mods would be required to defeat these systems, where can I get them? Would they void my warranty?
Thanks much,
