Its 3.5l without filter change and 3.7l with filter change
Be sure to install new crush washer at every oil change and lubricate the filter o-ring with oil as well. @Xulfiqar suggests to fill a bit of oil inside filter as well but dealership never does that and service manual also only talks about lubricating the seal...
I suggest you pour in 3.5l. Then in the morning next say, check dipstick and fill a little more if required
