FUSES
A vehicle’s electrical system is protected
from electrical overload damage by
fuses. This vehicle has 4 fuse panels, one locat-
ed in the driver’s side panel bolster,
another is in the front passenger’s side
panel bolster, the others are in the
engine compartment.
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 bemelted.
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.

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 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 any
other metal object to remove fuses because it may cause a short circuitand damage the system.

Instrument panel fuse replace- ment
1. Turn the engine start/stop button to the
OFF position.
2. Open the fuse panel cover. 3. Pull the suspected fuse straight out.
Use the removal tool provided on the
front passenger’s side panel.
4. Check the removed fuse; replace it if it is blown.
Spare fuses are provided in the pas-
senger compartment panel fuse panel(or in the engine compartment fuse panel).
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
HYUNDAI dealer.
If you do not have a spare, use a fuse of the same rating from a circuit you may not 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 mustbe replaced.

LIGHT BULBS
Use only the bulbs of the specified
wattage.
✽✽ NOTICE
After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between the
lamp inside and outside. This is similar
to the condensation on your windows
inside your vehicle during the rain and
doesn’t indicate a problem with your
vehicle. If the water leaks into the lamp
bulb circuitry, have the vehicle checked
by an authorized HYUNDAI dealer.

nal light, front fog light bulbreplacement

(5) Front fog light (if equipped)
WARNING - Working on
the lights
Prior to working on the light, firmly
apply the parking brake, ensure
that the ignition switch is turned tothe LOCK position and turn off the
lights to avoid sudden movement
of the vehicle and burning your fin-
gers or receiving an electric shock.
CAUTION
Be sure to replace the burned-out bulb with one of the same wattage
rating. Otherwise, it may causedamage to the fuse or electricwiring system.
CAUTION
If you don’t have necessary tools,the correct bulbs and the expertise,
consult an authorized HYUNDAIdealer. In many cases, it is difficultto replace vehicle light bulbs because other parts of the vehicle
must be removed before you canget to the bulb. This is especiallytrue if you have to remove the head-
light assembly to
get to the bulb(s).
Removing/installingthe headlight
assembly can result in damage to the vehicle.OVI079030
