pawn Код:

GetVehicleModel(GetPlayerVehicleID(playerid)) == 596 || 597 || 598 || 599 || 601 || 427

This is wrong. It hurts my eyes.

Try this:

pawn Код:

public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if(newstate == PLAYER_STATE_DRIVER)
    {
        new vmid = GetVehicleModel(GetPlayerVehicleID(playerid));
        if(vmid == 596 || vmid == 597 || vmid == 598 || vmid == 599 || vmid == 601 || vmid == 427)
        {
            if(gTeam[playerid] == CIV)
            {
                SendClientMessage(playerid, COLOR_RED, "WARNING: You just stole a police car, your wanted level has been increased!");
                SetPlayerWantedLevel(playerid, GetPlayerWantedLevel(playerid)+3);
            }
        }
    }
    return 1;
}
