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 vehicle 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
vehicle 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. Consult an
authorized HYUNDAI dealer.
WARNING NEVER replace a fuse with anything but
another fuse of the same rating.
• A higher capacity fuse may 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.
