Sorry, another question, I would like to know that how can I turn on the police car siren?

Please try to post a bit more information. Are you using ELS or just the default police cars?

In GTA IV, the default key to turn on the lights and siren is G.

If you dont have ELS, just press 'g.' If you are using ELS, hit 'g' for the siren, and 'j' and 'k' for the lights.

Thanks!

But how about version 0.91, when I press G, only singal 'ngat' sound, it looks like a normal horn instead of siren!

Okay ima ask a dumb question: Are you in a police car?

Tap the button.

Don't hold it down

Since were on the subject of ELS lights not working correctly I thought Id ask this in this topic. Is ELS supposed to be this complicated:

I have to make sure the GTA 4 siren is on, get out of the car, press J, then get back in and ELS will finally turn on. Once Im in the car and I turn the GTA IV siren off and press J, ELS stays on. I have to repeat the process to turn them off. Its pretty annoying. Im on 1070 and I can make a video if that explanation wasnt clear enough.
