WARNING: This page is about a different car, the 2021 Audi S4 and 2021 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

Health risk due to electrolyte.

To produce its unique properties, the interior rearview mirror glass is composed of several layers and contains an electrolyte. Be careful of electrolyte fluid leaking from a broken mirror.
The electrolyte fluid can cause irritation to the skin, eyes and respiratory system.
If electrolyte fluid comes into contact with the eyes or skin, flush thoroughly with plenty of water. If irritation persists, seek medical attention immediately.

CAUTION:

Electrolyte fluid leaking from a broken mirror will damage all plastic surfaces it comes in contact with. Remove spilled electrolyte immediately using clean water and a sponge.
