A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 (or 3) fuse panels, one
located 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 or broken.
If the electrical system does not work,
first check the driver's side fuse panel.
Before replacing a blown fuse, turn the
engine and all switches off, and then dis-
connect the negative battery cable.
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.
Information
Four kinds of fuses are used : blade type
for lower amperage rating, cartridge type/
Multi fuse/Battery fuse terminal for high-
er amperage ratings. Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and dam-
age the system.
NOTICE
i
NEVER replace a fuse with any-
thing but another fuse of the same
rating.
A higher capacity fuse could
cause damage and possibly
cause a fire.
Do not install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage
and possibly a fire.

Maintenance
Instrument Panel Fuse
Replacement
1. Turn the engine off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside of thefuse panel cover to locate the sus-
pected fuse location. 5. Pull the suspected fuse straight out.
Use the removal tool provided in the
engine compartment fuse panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are provided in
the instrument panel fuse panels (or in
the engine compartment fuse panel).
7. 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
HYUNDAI dealer. In an emergency, if you do not have a
spare fuse, use a fuse of the same rating
from a circuit you may not need for oper-
ating the vehicle.
If the headlamps 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 with the same rating.

Maintenance
Blade type fuse
Before inspecting a fuse, you should turn
OFF the engine as well as the other elec-
tric system switches.
If a fuse is blown out, remove the blown-
out fuse and install a new fuse of the
same capacity by using the fuse puller,
which is prepared inside the fuse box in
the engine compartment. A new fuse
may be prepared along with the fuse
puller. However, if not, you may tem-
porarily select/use a fuse of the other
systems, which do not affect the vehicle
operation, such as the audio system.
Cartridge type fuse
Before inspecting a fuse, you should turn
OFF the engine as well as the other elec-
tric system switches.
If a fuse is blown out, remove the blown-
out fuse and install a new fuse of the
same capacity. Pay extreme caution not
to damage the blown-out fuse while
removing it.

Maintenance Water washing in the engine com-partment including high pressure
water washing may cause the failure
of electrical circuits located in the
engine compartment.
Never allow water or other liquids to come in contact with electrical/elec-
tronic components inside the vehi-
cle as this may damage them.
Waxing
A good coat of wax provides a barrier
between your paint and environmental
contamination.
Keeping a good coat of wax on your vehi-
cle will help protect it.
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle before
waxing. Use a good quality liquid or
paste wax, and follow the manufacturer’s
instructions. Wax all metal trim to protect
it and to maintain its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing. Wiping dust or dirt off the body with
a dry cloth will scratch the finish.
Do not use steel wool, abrasive cleaners, or strong detergents con-
taining highly alkaline or caustic
agents on chrome-plated or
anodized aluminum parts. This may
result in damage to the protective
coating and cause discoloration or
paint deterioration.
Repairing your vehicle’s finish
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly rust
and may develop into a major repair
expense.
If your vehicle is damaged and
requires any metal repair or replace-
ment, be sure the body shop applies
anti-corrosion materials to the parts
repaired or replaced.
