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 be
melted.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, discon-
nect 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.
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 any
other metal object to remove fuses
because it may cause a short circuit
and 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 in 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.

• When replacing a blown fuse or
relay with a new one, make sure
the new fuse or relay fits tightly
into the clips. The incomplete fas-
tening fuse or relay may cause
the vehicle wiring and electric
systems damage and a possible
fire.
• Do not remove fuses, relays and
terminals fastened with bolts or
nuts. The fuses, relays and termi-
nals may be fastened incomplete-
ly, and it may cause a possible
fire. If fuses, relays and terminals
fastened with bolts or nuts are
blown, consult with an authorized
HYUNDAI dealer.
• Do not input any other objects
except fuses or relays into
fuse/relay terminals such as a
driver or wiring. It may cause con-
tact failure and system malfunc-
tion.
