I own Suzuki Cultus efi and Suzuki Baleno both ff cng.
Cultus does start directly on CNG by pressing the conversion switch once and then pressing again and holding it.
Baleno cannot be started directly on CNG. Pressing the switch once and then pressing again and holding it does not start the car directly on CNG. What it does is it starts on petrol and immediately converts on CNG but DOES NOT COMPLETELY START ON CNG. If any one knows how to start Baleno FF CNG directly on CNG please lemme know.
