In this article, you will find information about the fuses of the Toyota iQ (models 2012 and 2013), including diagrams of the fuse boxes, a list of fuses, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Toyota iQ
If any of the electrical components do not operate, a fuse may have blown. If this happens, check and replace the fuses as necessary. Replace it with one of an appropriate amperage rating. The amperage rating can be found on the fuse box lid.
Caution!
- Never use a fuse of a higher amperage rating than indicated, or use any other object in place of a fuse.
- Always use a genuine Scion fuse or equivalent. Never replace a fuse with a wire, even as a temporary fix. This can cause extensive damage or even fire.
- Do not modify the fuse or the fuse box.
Location of Fuse Boxes
Passenger Compartment Fuses:
Left-hand drive vehicles
Right-hand drive vehicles
- Remove the cover. Use a flathead screwdriver which is wrapped with a cloth.
- Remove the lid.
