Subaru Forester 2023 Fuses Base
Fuses
CAUTION
Never replace a fuse with one having a higher rating or with material other than a fuse because serious damage or a fire could result.
NOTE
Fuse rating and using circuit are described on each behind the fuse box cover. The fuses are designed to melt during an overload to prevent damage to the wiring harness and electrical equipment. The fuses are located in two fuse boxes.
One is located under the instrument panel behind the fuse box cover on the driver’s seat side. To remove the cover, pull it out. One is located under the instrument panel behind the fuse box cover on the driver’s seat side. To remove the cover, pull it out.
Spare fuses
The other one (the main fuse box) is housed in the engine compartment. Also, the spare fuses are stored in the fuse box cover.
The fuse puller is stored in the main fuse box in the engine compartment. Pinch the upper part of the fuse puller when removing it from the main fuse box.
- Good
- Blown
If any lights, accessories, or other electrical controls do not operate, inspect the corresponding fuse. If a fuse has blown, replace it.
- Turn the ignition switch to the “LOCK”/ “OFF” position and turn off all electrical accessories.
- Remove the cover.
- Determine which fuse may be blown.
Look at the back side of each fuse box cover.
- Pull out the fuse with the fuse puller
- Inspect the fuse. If it has blown, replace it with a spare fuse of the same rating.
- If the same fuse blows again, this indicates that its system has a problem. Contact your SUBARU dealer for repairs.
Installation of accessories
Always consult your SUBARU dealer before installing fog lights or any other electrical equipment in your vehicle. Such accessories may cause the electronic system to malfunction if they are incorrectly installed or if they are not suited for the vehicle.
Replacing bulbs
Bulbs may become very hot while illuminated. Before replacing bulbs, turn off the lights and wait until the bulbs cool down. Otherwise, there is a risk of sustaining a burn injury.
CAUTION
Replace any bulb only with a new bulb of the specified wattage. Using a bulb of different wattage could result in a fire.
NOTE
For models with type B combination meter, if SRH is malfunctioning, the SRH OFF indicator light appears on the combination meter when the ignition switch is in the “ON” position. It indicates that SRH has been deactivated. Contact a SUBARU dealer for an inspection.

FAQ
The fuse box is typically located in the engine compartment or the interior cabin of the Forester.
Fuses in the fuse box protect the vehicle’s electrical systems and components by interrupting the circuit in case of overcurrent or a short circuit.
Visually inspect the fuses for any visible damage, such as a broken filament, or use a fuse tester to check for continuity.
Replace the blown fuse with one of the same amperage rating to restore the electrical circuit’s functionality.
You can find this information in the owner’s manual or on the fuse box cover, which typically has a diagram detailing the fuse locations and their purposes.
No, it’s crucial to replace a blown fuse with one of the same amperage rating specified for that circuit. Using a higher-rated fuse can lead to electrical system damage or fires.
Some vehicles may come with spare fuses stored inside the fuse box or in a designated location nearby. Check the owner’s manual for details.
Yes, accessing the interior fuse box usually does not require special tools. A fuse puller may be included for easier removal of fuses.
Fuses protect various systems, including lighting, audio, power windows, power seats, and other electrical components.
Replacing fuses is a straightforward task and can often be done by the vehicle owner. However, if you’re unsure or uncomfortable with the process, consulting a professional is a good option.
Regularly check and replace any blown fuses, and ensure that the fuse box cover is securely in place to protect the fuses.
Yes, you can disconnect the vehicle’s battery as a safety precaution when working on the fuse box. Be sure to follow proper procedures for disconnecting and reconnecting the battery.
