I just dropped my car off today for this exact service (and annual CBS maintenance for low mileage vehicles). The in service date for the car was 5/30/17, so sliding it in under the wire! It's a lease and would normally be returned this weekend, but I went with the extension. On my own for scheduled maintenance, but shouldn't be an issue now.The 36 month brake fluid change starts counting when the car is made, not when it's bought. So, get that done during the initial lease period. Oil changes are 10k miles/12 months. So, you should get getting one those for free right near the end of the original 36-month lease period.
