G
In the case of an accident, liquid electrolyte
may escape the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or the respiratory sys-
tem. In case it does, immediately flush af-
fected area with water, and seek medical
help if necessary.!Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their liq-
uid state and by applying plenty of wa-
ter.
Warning!
G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
terior rear view mirror or glance over your
shoulder before changing lanes.
