1. Turn the ignition switch and all other switches off.
2. Open the fuse panel cover.
3. Pull the suspected fuse straight out. Use the removal tool provided in the engine compartment fuse panel.
4. Check the removed fuse; replace it if it is blown.
5. 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 authorized Kia dealer.
If you do not have a spare, use a fuse of the same rating from a circuit you may not need for operating the vehicle, such as the cigar lighter fuse.
If the headlights, fog lights, turn signal lights, position lights or interior lights do not work and there is nothing wrong with the bulbs, we recommend that you consult with an authorized Kia dealer.
