2007 KIA Optima engine

In case of an emergency66ELECTRICAL CIRCUIT PROTECTIONFuses A vehicle’s electrical system is protected
from electrical overload damage by
fuses.This vehicle has two 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, 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.
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 Kia dealer.
Two kinds of fuses are used: standard for
lower amperage rating and main for high-er amperage ratings.
Fuse replacement ✽ ✽ NOTICEDo not use a screwdriver or any other
metal object to remove fuses because it
may cause a short circuit and damage
the system.
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 through overheat-
ing and possibly a fire.
 Never install a wire instead of the proper fuse - even as a temporary
repair. It may cause extensive
wiring damage and possibly a
fire.
