You can't add car mods using Steam itself (that's what your thread title implies, anyways). You need to use a utility called SparkIV to open up GTA's data files (vehicles.img, specifically) and import car mods.

There are no mods can be installed with Steam. They all have to be done manually, opening up the GTA folder and then importing the data from the mod, based on what the mod readme file tells you to do. Same thing is true if you have the disc version.

I cannot place anything into my "vehicles.img"

Are you using SparkIV (found here, recommend using latest beta)? You need to use SparkIV to edit vehicles.img and then import the car mod. You'll need to make sure vehicles.img isn't marked as read-only. If it is, disable User Account Control (preferably, since it gets in the way a lot with mods) and mark vehicles.img as NOT read-only. Then try Spark again, making sure to run it as an administrator (right click, run as admin). Either do that every time, or right click spark iv --> properties --> compatibility --> always run as admin.

I seem to need "cryptographic keys" to start Spark IV?

Whatever that suppose to be? :P

It means you need to direct SparkIV to the correct installation folder where GTA is installed. This is the root GTA folder, so it should be steamsteamappscommongrandtheftautoivGTA IV since you have Steam.

Is it normal when you make a police veh mod, that the sirene's and lights arent modded at the same time? (sorry if it's hard to understand me im not american or english)

You probably installed an ELS-Enabled vehicle. You will need this mod to use the lights correctly. Alternatively, look for non-ELS vehicles.

I've downloaded the ELS V6.1, Do i need to use the "ELS.asi" file? or visualSettings.dat?

And wich directory do they need to be?

You will need to use ELS.ini and ELS.asi. I would recommend using the files from this mod rather than the visualsettings.dat from the ELS folder.

Both ELS.ini and ELS.asi should go in your main GTA folder, the same folder that contains gtaiv.exe (the readme file should explain it). Once installed, edit the .ini file so that the car you installed is set to active. So if you installed a car into the police2 slot, set active = 1. If it's in the Police slot, then set active = 1 under the [ POLICE ] heading.
