What type of fuse does a Subaru Outback use?
The Subaru Outback uses standard automotive blade fuses (ATO/ATC) for most circuits, with larger Maxi fuses in the under-hood power distribution center for high-current loads. The exact fuse types and amperage ratings can vary by model year and trim, so always check the owner's manual or fuse box diagram when replacing a fuse.
Fuse types you'll encounter
Here's a quick breakdown of the fuse families you’ll see in a Subaru Outback.
- Blade fuses (ATO/ATC) for the majority of interior circuits
- Mini blade fuses used in some supplemental or tighter-spaced circuits
- Maxi fuses (high-current) in the under-hood fuse/relay box
Most everyday circuits use blade or mini fuses, while Maxi fuses protect higher-current components such as power distribution and major accessories.
Where the fuses are located
Two main fuse boxes are standard on most Outback models: an interior panel and an under-hood box. The exact layout and numbering are shown on the cover of each fuse box and in the owner's manual.
- Interior fuse box location: typically under the dash on the driver's side (kick panel) with a removable cover
- Under-hood fuse/relay box: located in the engine bay near the firewall or components like the battery area, depending on year
Always refer to the fuse box diagram for circuit-by-circuit mapping and the correct amperage ratings.
How to read and replace fuses
Following a careful, methodical approach helps ensure you don’t damage circuits or miss a problem.
- Turn off the vehicle and locate the fuse box covers and diagrams.
- Identify the fuse corresponding to the circuit you’re servicing using the diagram.
- Carefully remove the fuse with the fuse puller (often built into the box) and inspect for a blown element.
- Replace with the same type (blade, mini, or Maxi) and the same amperage rating as the removed fuse.
- If the new fuse blows again, or if multiple fuses are affected, stop and inspect the circuit for a short or faulty component; seek professional help.
Using the correct fuse type and rating is essential for safety and reliability. Do not improvise with mismatched fuses or ratings.
Tips for safe fuse replacement
Before you reach for a fuse, keep these safety and best-practice tips in mind.
- Always replace with the exact fuse type (blade, mini, Maxi) and the same amperage rating
- A blown fuse can signal an underlying electrical fault—don’t ignore the warning
- Check for short circuits or malfunctioning devices in the affected system
- Keep a small assortment of common fuse ratings in your glove box
- Use the fuse puller tool and handle fuses gently to avoid damage to surrounding fuses
By following these guidelines, you’ll maintain the Outback’s electrical system with fewer surprises on the road.
Summary
In brief, the Subaru Outback relies on standard automotive blade fuses (ATO/ATC) for most circuits, plus Maxi fuses for high-current needs, with some mini fuses used in limited areas. Fuse locations typically include an interior panel and an under-hood box, and replacements should use the exact type and amperage indicated in the fuse diagram. For model-year-specific details, always consult the owner's manual or the fuse box cover diagram.
How do I know what type of fuse my car uses?
Your car most likely uses blade-type fuses, with common sizes including Micro2, Mini, Low-profile Mini, and standard ATO/ATC blade fuses. To know for sure, check the fuse diagram or cover of your car's fuse box, consult your owner's manual, or inspect the fuse itself for its amperage rating.
How to identify the correct fuse
- Check the fuse box lid or diagram: The most reliable method is to look at the diagram on the inside of the fuse box cover or in your owner's manual. This will show you which fuse type and amperage is needed for each slot.
- Inspect the fuse itself: If you can access the fuse, the amperage rating is printed on top of it. The color also indicates the amperage, but this can vary by fuse size, so it's best to check the number as well.
- Identify the fuse type: Fuses are visually different. You can tell if you have a Micro2, Mini, or other type by its physical appearance.
- Use a fuse puller: Your car's fuse box usually includes a plastic tool for pulling out fuses easily without damaging them.
Common types of automotive fuses
- Blade fuses: This is the most common type, where a plastic body protects metal prongs that plug into the fuse box. They come in different sizes:
- Micro2 and Micro3: Smaller than Mini fuses.
- Mini and Low-profile Mini: A very common type.
- ATO/ATC: The standard-sized blade fuse.
- Maxi: Larger fuses for high-current applications.
- Glass tube and ceramic fuses: While less common in modern vehicles, some older cars may use these types.
- Bosch and Lucas: Other historical or brand-specific types that may be found.
How do I know what type of fuse to use?
To identify the correct fuse, locate your vehicle's fuse box and check the fuse box diagram, which shows the amperage and location for each fuse. You can also inspect the blown fuse itself for an amperage rating or use the color-coding system for replacement. For specific applications, you may need to calculate the required current based on the device's wattage and the system voltage, adding a 25% safety margin to the calculation.

Steps to identify the correct fuse
- Locate the fuse box: This is typically found under the dashboard on the driver's side, though it could also be in the trunk or under the hood.
- Consult the fuse diagram: Open the fuse box and find the diagram or label, which is usually on the inside of the cover or on the box itself. This diagram shows which fuse corresponds to which component and its correct amperage rating.
- Inspect the fuse: If you have the blown fuse, look at the top of the plastic body for the amperage rating (e.g., "10A"). You can also compare its physical characteristics (e.g., size, shape, color) to common fuse types to narrow down the correct one.
- Use the color-coding system: If the amperage isn't visible, rely on the color of the fuse. Different colors correspond to different amperage ratings, though some colors are reused for different fuse types. For example, a red fuse is typically a 10A fuse, a blue fuse is 15A, and a yellow fuse is 20A.
- Calculate the fuse size (for new installations):
- Use the formula Current=WattageVoltagecap C u r r e n t equals the fraction with numerator cap W a t t a g e and denominator cap V o l t a g e end-fraction𝐶𝑢𝑟𝑟𝑒𝑛𝑡=𝑊𝑎𝑡𝑡𝑎𝑔𝑒𝑉𝑜𝑙𝑡𝑎𝑔𝑒 to find the component's normal operating current.
- Multiply the result by 1.251.251.25 to add a 25% safety margin.
- Choose the next standard fuse size that is equal to or greater than this value, but always lower than the wiring's capacity.
Factors to consider for any fuse
- Voltage rating: The fuse's voltage rating must be higher than the circuit's operating voltage to prevent premature failure.
- Current rating: The amperage rating indicates how much current a fuse can handle before it blows. Choosing a fuse with a higher rating than what is needed can lead to electrical damage or fires.
- Type and size: Ensure the fuse physically fits in the slot. There are various types of fuses, including blade fuses and others that are less common.
- Response time: Some applications may require a "fast-acting" fuse, while others need a "time-delay" fuse.
Where are the fuses in a Subaru Outback?
So right next to the steering wheel. There's a little panel that you just pull to open like that and then on the inside of the panel. There's a list of what all of these interior fuses do.
What is the most common problem with a Subaru Outback?

Engine and powertrain
- Excessive oil consumption: Many models, particularly older 2.5L engines, may burn oil between oil changes due to leaks from seals.
- Cooling system failures: Overheating can lead to blown head gaskets, and the cooling system itself is a common point of failure.
- CVT transmission problems: Some model years are more susceptible to issues like rough shifting or failure.
- Vibration during acceleration: Some owners report a shudder or vibration when accelerating.
- Older head gasket issues: The EJ-series engines (roughly 1997–2012) had an inherent head gasket failure problem, though this was mostly resolved in later models.
Body and electrical
- Weak windshields: The glass is prone to cracking from stress or minor impacts.
- Airbag defects: Some models have a history of airbag problems, leading to recalls.
- Electrical issues: Problems can include unexpected battery drain and issues with the ABS control module.
Other common issues
- Oxygen sensor failure: The front O2 sensor can fail, sometimes leading to a recall.
- Premature brake wear: Some models experience faster-than-average brake wear.
- Suspension wear and tear: Like many vehicles, suspension components will eventually wear out.
