There are 3 settings to the siren....When I hit the G key it goes to the one, and you have to hold down G to get to the other and hold it longer to get to the last.....How can you change the siren to different tones without holding the G button??? I also tried just tapping the G and it still wont change to the other tones

You have to hold it AFAIK. Otherwise people who use ELS can just tap a button to switch each tone of the siren but it won't make cars pull over.

as he said ^ go in the els ini file and change the siren key and then you can get the 3rd siren and not have to hold it. but the cars will not pull over.
