Mirrors: Service Precautions






Interior Rearview Mirror Safety Precautions


The glass in the interior rearview mirror consists of several layers and contains an electrolyte that controls the dimming. Be careful of the electrolyte, which can leak out if the mirror glass is broken.

The liquid electrolyte can cause irritation to the skin, eyes and respiratory system.

If liquid electrolyte comes in contact with eyes or skin, flush or rinse immediately with plenty of water. If irritation continues, see a doctor.


Liquid electrolyte leaking from a broken mirror will damage all plastic surfaces that come into contact with it. Clean spilled electrolyte immediately using water and a sponge.
