BATTERY
For best battery service
Keep the battery securely mount-ed.
Keep the battery top clean and dry.
Keep the terminals and connec- tions 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, discon-
nect the battery cables. Always read the following
instructions carefully when
handling a battery.
If any electrolyte gets into your eyes, flush your eyes
with clean water for at least
15 minutes and get immedi-
ate medical attention.
If electrolyte gets on your
skin, thoroughly wash the
contacted area. If you feel
pain or burning sensation,
get medical attention imme-
diately.
An inappropriately disposed battery can be harmful to the
environment and human
health. Dispose the battery
according to your local law(s)
or regulation.
The battery contains lead. Do
not dispose of it after use.

tery when the battery cables are con-
nected.
WARNING- Risk of explosion
Keep lit cigarettes and
all other flames or
sparks away from the
battery.
The battery contains hydrogen -- a highly
combustible gas which
will explode if it comes
in contact with a flame or
spark.
Keep batteries out of the reach of children
because batteries con-
tain highly corrosive
SULFURIC ACID and
electrolytes. Do not
allow battery acid to
contact your skin, eyes,
clothing or paint finish.

✽ ✽
NOTICE
The electronic system may not func-
tion correctly even when the engine
compartment and internal fuse
box’s individual fuses are not dis-
connected. In such case the cause of
the problem may be disconnection
of the main fuse (BFT type), which is
located inside the positive battery
terminal (+) cap.
Since the main fuse is designed more
intricately than other parts, have the
vehicle checked by an authorized
Kia dealer.CAUTION
Visually inspect the battery cap
to ensure it is securely closed.If the battery cap is not securelyclosed, moisture may enter thesystem and damage the electri-cal components.
