FUSES
A 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, accessories,
or controls do not work, check the appro-
priate 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 multi fuse for higher amperage ratings.
✽ ✽
NOTICE
The actual fuse/relay panel label may
differ from equipped items.
WARNING - Fuse
replacement
Never replace a fuse with anything
but another fuse of the same rat-
ing.
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.
CAUTION
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 sys-
tems 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 driv-
er or wiring. It may cause contact
failure and system malfunction.
