cover.
6. Check the removed fuse; replace it if
it is blown. Spare fuses are provided in
the instrument panel fuse panels (or in
the engine compartment fuse panel).
7. 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 retailer of Genesis Branded
products.
In an emergency, if you do not have
a spare fuse, use a fuse of the same
rating from a circuit you may not need
for operating the vehicle, such as the
cigarette lighter fuse.
If the headlights or other electrical
components do not work and the fuses
are undamaged, check the fuse panel
in the engine compartment. If a fuse is
blown, it must be replaced with the same
rating.
