Subaru Impreza 2023 Fuses Base Sedan

Fuse protection is how the 2023 Subaru Impreza guards against harm from electrical surges and malfunctions to its electrical components. Fuses are tiny, swappable parts positioned thoughtfully throughout the electrical system of the car. Every fuse is made to “blow” or break if it senses an electrical overload, protecting linked components from harm. Every fuse in the Impreza’s fuse box, which is usually found in the engine compartment and another within the car, is associated with a particular electrical circuit or part. The seamless functioning of the car’s electrical systems depends on proper maintenance and sporadic fuse inspections, underscoring Subaru’s dedication to dependability and safety.

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 (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.

1.  Good
2. Blown

If any lights, accessories, or other electrical controls do not operate, inspect the corresponding fuse. If a fuse has blown, replace it.

1. Turn the ignition switch to the “LOCK”/ “OFF” position and turn off all electrical accessories.
2. Remove the cover.
3. Determine which fuse may be blown.
   Look at the back side of each fuse box cover.
4. Pull out the fuse with the fuse puller.
5. Inspect the fuse. If it has blown, replace it with a spare fuse of the same rating.
6. 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

WARNING
Bulbs may become very hot while illuminated. Before replacing the 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.

Headlights (models with LED headlights)

LED headlight warning light (type B)
The LED headlight warning light illuminates if the LED headlights malfunction. Have your vehicle inspected at a SUBARU dealer as soon as possible.

Halogen headlight bulbs become very hot while in use. If you touch the bulb surface with bare hands or greasy gloves, fingerprints or grease on the bulb surface will develop into hot spots, causing the bulb to break. If there are fingerprints or grease on the bulb surface, wipe them away with a soft cloth moistened with alcohol.
