What is the recommended maintenance schedule for the 1990 Audi 80's timing belt?

I recently purchased a 1990 Audi 80 and was wondering about the proper maintenance schedule for the timing belt. I want to ensure that I am taking care of my car properly to avoid any potential issues in the future.

The timing belt on the 1990 Audi 80 should be replaced every 60,000 miles or 6 years, whichever comes first. It is important to stick to this schedule to avoid potential engine damage.
