Fuse Box Diagram
Engine Compartment Fuse Box
- WARNING: Always disconnect the battery before servicing high current fuses.
- WARNING: To reduce the risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.
Note
- If your vehicle has dual batteries, disconnecting the primary under hood battery does not remove power from all circuits.
- The engine compartment fuse box is in the engine compartment. It has high-current fuses that protect your vehicle’s main electrical systems from overloads.
- If you disconnect and reconnect the battery, you need to reset some features. See Changing the 12V Battery (page 174).
- Replace fuses with the same type and rating. See Changing a Fuse (page 160).
Note: Spare fuse amperage may vary.

Passenger Compartment Fuse Box
WARNING: Always disconnect the battery before servicing high current fuses.
Note: If your vehicle has dual batteries, disconnecting the primary under hood battery does not remove power from all circuits. The fuse panel is to the left-hand side of the brake pedal and mounted onto the lower left-hand cowl panel. Remove the fuse panel cover to access the fuses.
To remove a fuse, use the fuse puller tool provided on the inside of the fuse panel cover.
Replace fuses with the same type and rating. See Changing a Fuse (page 160).
