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.
If the headlamps or other electrical
components do not work and the
fuses are undamaged, check the
fuse panel in the engine compart-
ment. If a fuse is blown, it must be
replaced with the same rating.
Engine Compartment Panel Fuse Replacement
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.
