Warning!
G
In the case of an accident liquid electrolyte
may escape from the mirror housing if the
mirror glass breaks.
Electrolyte has an irritating effect. Do not
allow the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.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
interior rear view mirror or glance over your
shoulder before changing lanes.
!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state by applying plenty of water.
