How can I check the tire pressure in my Audi A1?

I recently purchased a used Audi A1 and want to make sure the tires are properly inflated. How can I check the tire pressure on my own without having to go to a mechanic?

To check the tire pressure in your Audi A1, you will need a tire pressure gauge. First, remove the valve cap from the tire and place the gauge over the valve stem. The gauge will show the current pressure reading. Compare this to the recommended pressure listed in your owner's manual. If the pressure is too low, add air using a tire pump until it reaches the recommended level. Do not overinflate as it can be dangerous while driving.
