If you take a look inside the fuse box of your Kia or Hyundai vehicle, you may have noticed the OFF/ON switch. You may be wondering what this switch does.

When the fuse switch is turned OFF, multiple accessories on your car will not work.

If you have problems with accessories not working, such as no radio, cigarette outlet, power windows, etc., make sure the switch is turned on.

Here is a list that will stop working with the fuse switch in OFF position:

  • radio
  • clock
  • power seats
  • windows
  • smart key

You will need to set the clock if you turn the switch OFF and then back ON.

If you plan on operating your Kia/Hyundai, always have the FUSE SWITCH in the ON position.

When should you use the ON / OFF switch?

Use the fuse box ON/OFF switch if you plan on parking your vehicle for a period of time or if your vehicle is being transported.

By turning the fuse in the OFF position, your car battery is less likely to drain by unnecessary accessories, or parasitic current draws.
