Fuses

This Fuses manual  describes Subaru Legacy and Subaru Outback  vehicle types.

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.

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.

Instrument Fuse Box Location

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.

Engine Compartment Fuse Box

1) Spare fuses
2) Fuse puller

The other one (main fuse box) is housed in the engine compartment. Also, the spare fuses and fuse puller are stored in the fuse box cover. 

Pinch the upper part of the fuse puller when removing it from the main fuse box.

1) Good Fuse , 2) Blown Fuse

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 fuse box cover.
3. Determine which fuse may be blown.

Fuse Puller

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.
