Hi,

In my previous car, if there is car in the blind spot and I activate the turn signal, it will beep to warn. Is there a way to make Lexus do the same?

Thanks

 

I've found no sound setting, only alert timing. Seems this does not ever beep. i thought this odd at first as well but I like it better now and its made me more aware as Im looking for the light vs just turning and listening. Set it for EARLIER and you'll always be aware

 

Did you get an answer this? I have the same question and I think the answer is no it doesn't make the audibke beep in addition to the visual alert on the mirror when changing lanes.
