FUSES

■ Blade type

A vehicle’s electrical system is pro-

tected from electrical overload dam-

age by fuses.

i

Information

Four kinds of fuses are used : blade

type For lower amperage rating, car-

tridge type/Multi fuse/Battery fuse

terminal for higher amperage ratings.

This vehicle has 2 (or 3) fuse panels,

one located in the driver’s side panel

bolster, the other in the engine com-

partment near the battery.

Normal

Blown

■ Cartridge type

WARNING

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 or broken.

NEVER replace a fuse with any-

thing but another fuse of the

same rating.

Normal

Blown

• A higher capacity fuse could

cause damage and possibly

cause a fire.

• Do not install a wire or alu-

minum foil instead of the

proper fuse - even as a tem-

porary repair. It may cause

extensive wiring damage and

possibly a fire.

■ Multi fuse

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 rat-

ing.

If the replacement fuse blows, this

indicates an electrical problem. Avoid

using the system involved and imme-

diately consult an authorized

HYUNDAI dealer.

NOTICE

Do not use a screwdriver or any

other metal object to remove

fuses because it may cause a

short circuit and damage the sys-

tem.

Maintenance

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.

Instrument Panel Fuse

Replacement

If the headlamps or other electrical

components do not work and the

fuses are OK, check the fuse panel

in the engine compartment. If a fuse

is blown, it must be replaced with the

same rating.

5. Pull the suspected fuse straight

out. Use the removal tool provided

in the engine compartment fuses

panel.

OTLE078023

1. Turn the engine off.

2. Turn all other switches OFF.

3. Open the fuse panel cover.

4. Refer to the label on the inside of

the fuse panel cover to locate the

suspected fuse location.

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 com-

partment 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.

1. Turn the engine off.

2. Turn all other switches OFF.

3. Remove the fuse panel cover by

pressing the tap and pulling up.

4. Check the removed fuse; replace

it if it is blown. To remove or insert

the fuse, use the fuse puller in the

engine compartment fuse panel.

5. 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.
