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

surface is convex (outwardly curved surface 
for a wider field of view). Objects in mirror 
are closer than they appear. Check your
