At the least, I would fully charge the car, drive it until the REx kicks in, note the miles, and keep driving it on REx for a while.
Before depleting the battery to where the REx should start (about 6%) I would first make sure the REx starts and runs. You can do that any time the charge is under 75% and the fuel tank is not empty:
BMW i3 REx test mode
Get into the car and close the door.
Press the trunk release button
Press the Start/Stop button (BRAKE NOT PRESSED)
Press and hold the accelerator pedal.
Press and release the brake pedal.
Press and release the brake pedal again.
Press and hold the brake pedal.
Release the accelerator pedal.
Press the Start/Stop button.
The REx should start and run at low-idle.
If you press the accelerator pedal the REx switches to high idle.
The REx will stop in 20 minutes or when you press the Start/Stop button.
Be sure to get out of the car and re-close the trunk when you are done.
