How to change a flat tire on an Audi A3?

I recently had a flat tire on my Audi A3 and I need to know the best way to change it. I'm on the side of the highway and don't have any professional help available. Can someone walk me through the steps?

First, make sure your car is parked on a flat surface and turn on your hazard lights. Next, locate your spare tire, jack, and lug wrench. Remove the hubcap and loosen the lug nuts before raising the car with the jack. Once the car is off the ground, remove the lug nuts completely, swap the tires, and tighten the lug nuts in a star pattern. Lower the car and voila!

Don't try to change the tire on your own if you don't feel comfortable. Instead, call for roadside assistance or a friend who has experience changing tires. It's better to be safe than sorry!
