Maintenance
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. When recharging the battery, observe
the following precautions:
The battery must be removed from the
vehicle and placed in an area with
good ventilation.
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 checking 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
accessories and stop the engine.
The negative battery cable must be removed first and installed last when
the battery is disconnected.
Reset items
Items should be reset after the battery
has been discharged or the battery has
been disconnected.

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.
✽ ✽ NOTICE
The actual fuse/relay panel label may
differ from equipped items.
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 - Fuse
replacement
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 replacement
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, suchas the cigar lighter fuse.
If the headlights or other electrical com-
ponents do not work and the fuses are
OK, check the fuse block in the engine
compartment. If a fuse is blown, it must
be replaced.
Memory fuse
Your vehicle is equipped with a memory
fuse to prevent battery discharge if your
vehicle is parked without being operated
for prolonged periods. Use the following
procedures before parking the vehicle for
prolonged periods.
1. Turn off the engine.
2. Turn off the headlights and tail lights.
3. Open the driver’s side panel cover and pull up the memory fuse.

• Even when the memory fuse is pulled up, the battery can still be discharged
by operation of the headlights or other
electrical devices.
Engine compartment panel fuse
replacement
1. Turn the ignition switch and all other switches off.
2. Remove the fuse box cover by press- ing the tap and pulling up the cover.

If it fits loosely, consult an authorized
Kia dealer.
