For best battery service
Keep the battery securely mounted.
Keep the battery top clean and dry.
Keep the terminals and connections
clean, tight, and coated with petroleum
jelly or terminal grease.
Rinse any spilled electrolyte from the battery immediately with a solution of
water and baking soda.
If the vehicle is not going to be used for an extended time, disconnect the bat-
tery cables.
✽✽ NOTICE
Basically equipped battery is mainte-
nance free type. If your vehicle is
equipped with the battery marked with
LOWER and UPPER on the side, you
can check the electrolyte level. The elec-
trolyte level should be between LOWER
and UPPER. If the electrolyte level is
low, it needs to add distilled (demineral-
ized) water (Never add sulfuric acid or
other electrolyte). When refill, be careful
not to splash the battery and adjacent
components. And do not overfill the bat-
tery cells. It can cause corrosion on other
parts. After then ensure that tighten the
cell caps. We recommend that you con-
tact an authorized HYUNDAI dealer.WARNING - Battery
dangers
Always read the following
instructions carefully when
handling a battery.
Keep lighted cigarettes and all other flames or sparks
away from the battery.
Hydrogen, a highly com- bustible gas, is always
present in battery cells and
may explode if ignited.
Keep batteries out of the
reach of children because
batteries contain highly
corrosive SULFURIC ACID.
Do not allow battery acid to
contact your skin, eyes,
clothing or paint finish.
If any electrolyte gets into your eyes, flush your eyes
with clean water for at least
15 minutes and get immedi-ate medical attention.
