Many Congrats brother,
is it with Dual headlights with HID ?
Passo or (all new/japanese cars doesnt give tucc sound) it just stay calm, a lil load is felt on engine,
if you feel some difference is engine sound, load , etc. then the compressor is turned on, and most probably the AC gas is not filled.
but if the compressor doesnt turned on, then first of all check the Fuses, its in the dashboard, under the glove box,
you can check my thread for exact location,
