Maintenance

FUSES

A vehicle’s electrical system is protected

from electrical overload damage by

fuses.

Ŷ

Blade type

This vehicle has 5 fuse panels, one

located in the driver’s side panel bolster,

the other in the vehicle compartment.

If any of your vehicle’s lights,

Normal

Blown

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.

Ŷ

Cartridge type

If the electrical system does not work,

first check the driver’s side fuse panel.

Before replacing a blown fuse, turn the

vehicle and all switches off, and then

disconnect the negative battery cable.

Always replace a blown fuse with one of

the same rating.

Normal

Blown

If the replacement fuse blows, this

indicates an electrical problem.

Avoid using the system involved. We

recommend that you immediately

consult an authorised HYUNDAI dealer.

Ŷ

Multi type

WARNING

NEVER replace a fuse with anything but

another fuse of the same rating.

śꢀ A higher capacity fuse could cause

Normal

Blown

damage and possibly cause a fire.

OTM078035

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.

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 (1) provided in

the motor compartment fuses panel

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 motor 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 an authorised

HYUNDAI dealer.

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 fuse location.

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 headlamps or other electrical

components do not work and the fuses

are undamaged, check the fuse panel

in the motor compartment. If a fuse is

blown, it must be replaced with the same

rating.

Maintenance

NOTICE

Motor compartment panel fuse

After checking the fuse panel in the

motor compartment, securely install
