7FUSESA 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.
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 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 any
other metal object to remove fuses because it may cause a short circuitand damage the system.

Maintenance
APPEARANCE CAREExterior careExterior general caution It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.Finish maintenanceWashing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are kept
clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
CAUTION
 Do not use strong soap, chemical
detergents or hot water, and donot wash the vehicle in directsunlight or when the body of the vehicle is warm.
 Be careful when washing the side windows of your vehicle.Especially, with high-pressure water, water may leak through thewindows and wet the interior.
 To prevent damage to the plastic parts and lamps, do not cleanwith chemical solvents or strong detergents.
WARNING -
Wet brakes
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.
CAUTION
 Water washing in the engine com- partment including high pressurewater washing may cause the fail-ure of electrical circuits or engineand related components locatedin the engine compartment.
 Never allow water or other liquids to come in contact with electri-cal/electronic components andair duct inside the vehicle as this may damage them.
