FUSES

ꢀBlade type

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 we

recommend that all inspect a HYUNDAI

authorised repairer.

WARNING

NEVER replace a fuse with anything but

another fuse of the same rating.

śꢀ A higher capacity fuse could cause

damage and possibly cause a fire.

OTA070039

A vehicle’s electrical system is protected

from electrical overload damage by

fuses.

śꢀ Do not install a wire or aluminium

foil instead of the proper fuse -

even as a temporary repair. It may

cause extensive wiring damage and

possibly a fire.

This vehicle has 2 (or 3) fuse panels, one

located in the driver’s side panel bolster,

the other in the engine compartment.

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.

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.

Instrument panel fuse

replacement

OBC3N091018AU

5. Pull the suspected fuse straight out.

Use the removal tool provided in the

engine compartment fuses panel.

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, we recommend

that you consult with a HYUNDAI

authorised repairer.

OBC3N091016AU

1. Turn the vehicle 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 broken fuse location.

In an emergency, if you do not have a

spare fuse, use a fuse of the same rating

from a circuit 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.

Maintenance

Multi fuse (Main fuse)

Engine compartment panel fuse

replacement

OBC3N091019AU

If the multi fuse is blown, it must be

removed as follows:

1. Turn the vehicle off.

2. Disconnect the negative battery cable.

3. Remove the fuse panel cover by

pressing the tab and pulling it up.

4. Remove the nuts shown in the picture

above.

5. Replace the fuse with a new one of

the same rating.

6. Reinstall in the reverse order of

removal.

OBC3N090020

1. Turn the vehicle off.

2. Turn all other switches OFF.

3. Remove the fuse panel cover by

pressing the tab 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 does not fit tightly,

we recommend that you consult a

HYUNDAI authorised repairer.

If the multi fuse is blown, we

recommend that you consult with a

HYUNDAI authorised repairer.

NOTICE

After checking the fuse panel in the

engine compartment, securely

install the fuse panel cover. You may

hear a clicking sound if the cover is

securely latched. If it is not securely

latched, electrical failure may occur

from water contact.
