ming mirrors if the glass is broken. Electro­
lyte fluid can irritate skin, eyes and respirato­
ry system.
- Repeated or prolonged exposure to electro­
lyte can cause irritation to the respiratory
system, especially among people with asth­
ma or other respiratory conditions. Get
fresh air immediately by leaving the vehicle
or, if that is not possible, open windows and
doors all the way.
- If electrolyte gets into the eyes, flush them
thoroughly with large amounts of clean wa­
ter for at least 15 minutes; medical atten­
tion is recommended.

- If electro lyte contacts skin, flush affected
area with clean water for at least 15 mi­
nutes and then wash affected area with
soap and water; medical attention is recom­ mended . Thoroughly wash affected clothing
and shoes before reuse.
- If swallowed and person is conscious, rinse mouth with water for at least 15 minutes.
Do not induce vomiting unless instructed to
do so by medical professional. Get medical
attention immediately.

If the glass on an automatic dimming mirror
breaks, electrolyte can leak out. This liquid
damages plastic surfaces. Clean this liquid as
quickly as possible, for example with a wet
sponge.
