Turn the key to on but DON'T START THE CAR, then just wait and do NOTHING for about 10 seconds until you see the odometer mileage disappear and an oil pictogram and a little clock appear on the display. When this appears push the button on the left in twice and it will display your oil level. If it reads OK then you're fine, if it doesn't display a reading then the car is not level or all the oil hasn't drained down into the pan yet after driving in which case you'll have to wait about 10 minutes or so then try again. It's real simple.
