A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 5 fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment.
If any of your vehicle’s lights,
accessories, 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
disconnect the negative battery cable.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this
indicates an electrical problem.
Avoid using the system involved. We
recommend that you immediately
consult an authorized HYUNDAI dealer.
WARNING
NEVER replace a fuse with anything 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.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.

NOTICE
ONX4090036
• Water washing in the engine
compartment 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/
electronic components inside the
vehicle as this may damage them.
NOTICE
Matte paint finish vehicle (if equipped)
Automatic car wash which uses rotating
brushes should not be used as this can
damage the surface of your vehicle. A
steam cleaner which washes the vehicle
surface at high temperature may result
the oil to adhere and leave stains that is
difficult to remove.
Use a soft cloth (e.g. microfiber towel
or sponge) when washing your vehicle
and dry with a microfiber towel. When
you hand wash your vehicle, you should
not use a cleaner that finishes with wax.
If the vehicle surface is too dirty (sand,
dirt, dust, contaminant, etc.), clean the
surface with water before washing the
car.
Waxing
A good coat of wax is a barrier between
your paint and contaminate. Keeping
a good coat of wax on your vehicle 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.
NOTICE
• 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
containing 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.
NOTICE
Matte paint finish vehicle (if equipped)
Do not use any polish protector such as
a detergent, an abrasive and a polish.
In case wax is applied, remove the wax
immediately using a silicon remover
and if any tar or tar contaminant is on
the surface use a tar remover to clean.
However, be careful not to apply too
much pressure on the painted area.
