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 battery connector. 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.

[A higher capacity fuse could 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.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.

5. Pull the suspected fuse straight out. Use the removal tool provided in the
engine compartment fuse panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are provided 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 HYUNDAI dealer.
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.
If the 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.
If the headlight, turn signal lamp, tail
lamp, interior lamp doesn’t work and
the fuses are undamaged, consult an
authorized HYUNDAI dealer.

3. Exhaust Emission Control System
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
When the engine starts or fails to start,
excessive attempts to restart the engine
may cause damage to the emission
system.
Engine exhaust (carbon monoxide)
precautions

[ Carbon monoxide can be present
with other exhaust fumes. If you smell
exhaust fumes of any kind in your
vehicle, drive with all the windows
fully open. Have your vehicle checked
and repaired immediately.
WARNING
Engine exhaust gases contain carbon
monoxide (CO). Though colorless and
odorless, it is dangerous and could be
lethal if inhaled. Follow the instructions
on this page to avoid CO poisoning.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the
interior furnishings in a vehicle, contain
or emit chemicals known to the State
of California to cause cancer and
birth defects and reproductive harm.
In addition, certain fluids contained
in vehicles and certain products of
component wear contain or emit
chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
[
Do not operate the engine in confined
or closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area.

[ When the vehicle is stopped in an
open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.

[ Never sit in a parked or stopped
vehicle for any extended time with the
engine running.

[ When the engine stalls or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission control system.
