Fuses — General Description (Hyundai Elantra XD)

Fuses are used to break the circuit when the current reaches a certain value, in order to protect components and wires that could be damaged by too much current. A sudden increase in current is usually caused by a fault in the circuit, most often a short circuit.

The designations of the circuits protected by the fuses are indicated on the fuse box cover.

Before removing a fuse, turn off the corresponding circuit (or ignition), then remove the fuse from the contacts. There should be a wire visible inside the fuse; if the fuse is blown, the wire will be broken or melted.



Always use fuses of the correct rating. Never use a fuse of a different rating or replace it with anything else.



Do not replace a fuse more than once without eliminating the source of the fault. The current protected by the fuse is indicated on the top of the fuse: note that fuses are colour coded for easy identification.





If a fuse blows immediately after replacement, do not replace it again until you have installed it and corrected the cause of the problem. In most cases, the cause of the malfunction is a short circuit caused by poor insulation. If the fuse protects multiple circuits, try to find the circuit that is causing the fuse to blow by turning on each circuit in turn (if possible). Always keep a set of spare fuses of different ratings in your vehicle. They should be secured to the base of the fuse box.
