Hidden switch on 2000 Ls430

[Caractacus]

I have 'found' a rotary switch, ( very similar to a on/off volume switch for a radio ) under the drivers favia; roughly above where my right knee is when driving.    No idea what it does so advice please.

 

Also anyone got a  instruction manual for a Ls400 and/or Ls430 please, willing to pay reasonable amount.  NOT repair manual and not SatNav manual, but vehicle manual.

On earlier models it adjusted the bleep noise level when the car is locked/unlocked using the remote key fob, if it clicks at one end this should turn off the bleep completely.

Thanks indeed.   Had car almost 12 months and just found it.  It does indeed click, so i will give it a try tomorrow,  it was 'switched' off so i never heard anything.  Amazing what Lexus has fitted?

Have sourced a Ls400 manual, so just seeking a Ls430 now.

Doesn't that dim the dashboard at night?
