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.

an authorized Kia dealer to
be recycled.
Never attempt to recharge the bat-
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.

Maintenance
✽ ✽NOTICE
If you connect unauthorized elec-
tronic devices to the battery, the bat-
tery may be discharged. Never use
unauthorized devices.
Recharging the battery
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged
in a short time (because, for exam-
ple, the headlamps or interior
lamps were left on while the vehi-
cle was not in use), recharge it by
slow charging (trickle) for 10 hours.
If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.WARNING- Risk of elec-
trocution
Never touch the electrical igni-
tion system while the vehicle is
running. This system works
with high voltage which can
shock you.
WARNING- Recharging Battery
Never attempt to recharge the
battery when the battery cables
are connected.
WARNING- Battery lead
compound
Battery posts, terminals, and
related accessories contain
lead and lead compounds.
Wash hands after handling.

The battery must be removed from
the vehicle and placed in an area
with good ventilation.
Do not allow cigarettes, sparks, or flame near the battery.
Watch the battery during charging, and stop or reduce the charging
rate if the battery cells begin
gassing (boiling) violently or if the
temperature of the electrolyte of
any cell exceeds 49°C (120°F).
Wear eye protection when check- ing the battery during charging.
Disconnect the battery charger in the following order.
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal. Before performing maintenance or
recharging the battery, turn off all

Maintenance
High-pressure washing
When using high-pressure wash-ers, make sure to maintain suffi-
cient distance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
Do not spray the camera, sensors or its surrounding area directly with
a high pressure washer. Shock
applied from high pressure water
may cause the device to not oper-
ate normally.
Do not bring the nozzle tip close to boots (rubber or plastic covers) or
connectors as they may be dam-
aged if they come into contact with
high pressure water.
OJB037800
CAUTION - Wet engine
Water washing in the engine compartment, including highpressure water washing, maycause the failure of electricalcircuits located in the enginecompartment.
Never allow water or other liq- uids to come in contact withelectrical/electronic compo-nents inside the vehicle asthis may damage them.
(Continued)
(Continued) To prevent damage to the charging door, make sure toclose and lock the vehicledoors when washing (highpressure washing, automaticcar washing, etc.) the vehicle.
