How to adjust the headrest in an Audi A8?

I have a problem adjusting the headrest in my Audi A8. It seems to be stuck and won't move up or down. How can I fix this issue?

To adjust the headrest in an Audi A8, first check to see if there is a button or lever located on the side of the headrest. If so, use this to adjust the height and angle of the headrest. If the headrest is still stuck, try using a lubricant spray on the joints to help loosen it.

In some Audi A8 models, there may be a hidden release button behind the headrest. Check your owner's manual for more specific instructions on locating and using this button. If the headrest is still stuck, it may be a mechanical issue and you should take your car to a certified mechanic.
