Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in ashort time (because, for example, the
headlights or interior lights were left on
while the vehicle 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.(Continued)
When lifting a plastic-cased bat-tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
Never attempt to recharge the battery when the battery cables
are connected.
The electrical ignition system works with high voltage. Never
touch these components with the
engine running or the ignition
switched on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.CAUTION
When you don’t use the vehicle for a long time in the low temper-ature area, separate the batteryand keep it indoors.
Always charge the battery fully to prevent battery case damage inlow temperature area.
If you connect unauthorized elec- tronic devices to the battery, thebattery may be discharged. Never use unauthorized devices.
WARNING
Separating the battery from the
vehicle should be done in an
authorized Kia dealer.

When recharging the battery,
observe the following precautions:
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 charg- ing, and stop or reduce the charg-
ing 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.

FUSES
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 fuse panels, one locat-
ed in the driver’s side panel bolster, the
other in the engine compartment near
the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check the
appropriate circuit fuse. If a fuse has
blown, the element inside the fuse will
melt.
If the electrical system does not work,
first check the driver’s side fuse panel.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid using
the system involved and immediately
consult an authorized Kia dealer.
Three kinds of fuses are used: blade typefor lower amperage rating, cartridge type,and multi fuse for higher amperage rat-ings.
WARNING - Fuse replace- ment
Never replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse could cause damage and possibly a
fire.
Never install a wire or aluminum foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage
and a possible fire.
CAUTION
Do not use a screwdriver or anyother metal object to remove fuses because it may cause a short circuitand damage the system.

Instrument panel fuse replace-
ment
1. Turn the ignition switch and all other
switches off.
2. Open the fuse panel cover. 3. Pull the suspected fuse straight out.
Use the removal tool provided in the
engine compartment fuse panel.
4. Check the removed fuse; replace it if it is blown.
5. Push in a new fuse of the same rating, and make sure it fits tightly in the clips.
If it fits loosely, consult an authorized Kia
dealer.
If you do not have a spare, use a fuse of the same rating from a circuit you maynot need for operating the vehicle, such as the cigarette lighter fuse.
If the headlights or other electrical com-
ponents do not work and the fuses are
OK, check the fuse panel in the engine
compartment. If a fuse is blown, it must
be replaced.
