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.
If electrolyte gets on your skin, thoroughly wash the
contacted area. If you feel a
pain or a burning sensa-
tion, get medical attention
immediately.

battery. Always provide
ventilation when working in
an enclosed space.
An inappropriately disposed battery can be harmful to
the environment and human
health. Dispose the battery
according to your local
law(s) or regulation.
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

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.
G130300AUN
Reset items
Items should be reset after the battery
has been discharged or the battery has
been disconnected.

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 120°F (49°C).
(Continued)
(Continued)
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.

FUSES
G210000AFD
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 be
melted.
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 HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type, and fusible link 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
Do not use a screwdriver or anyother metal object to remove fuses because it may cause a short circuitand damage the system.

Inner 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 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 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.
