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.!
Electrolyte liquid coming into contact with
the vehicle paint finish can be completely
removed only while in the liquid state and by
applying plenty of water.

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.
