Question regarding the beeps in the new Sirion


Hello all

I have a "tricky" question regarding the new Sirion 2007 1.3 automatic.
When I insert the key into the switch with my door open or when I put into reverse gear, I hear those annoying beep sounds...Is there any way of disable those sounds without disconnecting the small speaker?
I know that in some cars it is possible to get a certain access to the cars computer if I press a certain sequence on the "Mile reset knob" is it possible in this car? if so, how can I disable those annoying beeps?

Thanks a lot!
