- Houses the primary fuses and relays controlling essential systems such as the dashboard, audio system, and internal electronics.
Engine Compartment Fuse Box
- Situated in the engine bay, often near the battery or along the firewall.
- Contains fuses and relays for engine management, cooling fans, headlights, and other critical engine components.
Additional Fuse Boxes (if applicable)
- Some models or trims may include additional fuse boxes for specific systems like towing or hybrid components.
- Always refer to your vehicle’s owner manual for exact locations.

Understanding the Fuse Box Diagram
A fuse box diagram is a schematic that displays the layout of fuses and relays within the fuse box. It indicates:
- The position of each fuse (numbered or labeled).
- The amperage rating of each fuse.
- The function or protected system of each fuse.
- The location of relays and their functions.
Reading the diagram correctly helps identify which fuse protects a specific component, making troubleshooting more efficient.
How to Read a Fuse Diagram
- Identify the layout: Many diagrams are numbered or lettered, with corresponding labels.
- Match labels to components: Fuses are labeled with abbreviations or system names (e.g., IG1 for interior lights, ECU for engine control unit).
- Check fuse ratings: Fuses are rated in amperes (A). Replacing a fuse with one of a different rating can cause damage.
- Locate the fuse physically: Use the diagram as a reference to find the actual fuse in the box.
