Okay guys,
I just did a track day at 'Seca today and I think I'm noticing something different when I turn the ignition on...4 beeps, precisely. I uploaded a clip on youtube. Please watch and advise!!!!
Is it the multi-function computer cycling through? I'm clueless!

is tire press low?

 

I don't think it is low, and I thought the low tp warning was visual only?

Tire pressuures went up at the track, up to 48psi, but return to normal.

 

tp can make a sound on start-up, and over pressure will set it off as well, does it beep every time you start it up? if so, I would drop the air in all tires to 35 to 38, than shut off the car and restart to see if the beep goes away.

 

Ahh I see, thanks for the tip! I will try that tonight. Yes, it's been doing that everytime now since yesterday. But I've never added/taken away pressure from the tires

 

Well, I let some air out, and it is still doing the 4-beep thing. I let enough out so that pressure cold was 35 all around....it increased to 38/38 at 85mph on the freeway so I know that the TPS is functioning properly.

 

It was a seatbelt beep. Put my belt on before turning the ignition on an voila...no 4 beeps.
Mods feel free to delete.

 

Oh, must be a new feature in the '06 models. No wonder the rest of us didn't really know.
