I was reading on the apr site that switching the programs isdon "on the fly", ie performance to valet. everything i've read on this site says that you ha to turn the car off and then back (cycle the ignition) for the change to take effect. i would like not to turn the car off then on before i hand the keys to the valet guy, or to my wife, j/k. can anyone clarify this? or can anyone with firsthand experience elaborate?
