How do I adjust the height of my Audi A1's rear seat headrests?

I can't seem to find any levers or buttons to change the height of the headrests in the back seat of my Audi A1. Is there a specific mechanism I should use or do I need to take it to the dealership?

The rear seat headrests in the Audi A1 can be adjusted manually by pulling them up or pushing them down. Simply grasp the headrest and move it to the desired height.

In some models of the Audi A1, the rear seat headrests can only be adjusted by the dealership. Check your owner's manual or contact your local dealership for more information.

If your Audi A1 has the optional Comfort package, the rear seat headrests can be electronically adjusted using the buttons on the side of the seat. Be sure to check for this feature before trying to adjust the headrests manually.
