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 respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
Warning!

Exercise care when using the passenger
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.!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.

height, seat position fore and aft, and
seat backrest angle if necessary, to en-
sure adequate control, reach and com-
fort. The head restraint should also be
adjusted for proper height. See also the

tioning.

ensure adequate control, reach, opera-
tion and comfort. Both the interior and
outside rear view mirrors should be ad-
justed for adequate rear vision.
