prevent the vehicle from starting. If the
12V battery is over discharged to a point
that the reset does not work, try to jump-
start the vehicle.

A vehicle’s electrical system is protected
from electrical overload damage by fuses.
This vehicle has 2 (or 3) fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment
near the battery.
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 and
immediately consult an authorized
HYUNDAI dealer.
WARNING
NEVER replace a fuse with anything but
another fuse of the same rating.
