Power Distribution Box

WARNING   WARNING:  Always disconnect the battery before servicing high current fuses.
WARNING   WARNING:  To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.

The power distribution box is in the engine compartment. It has high-current fuses that protect the vehicle’s main electrical systems from overloads.If you disconnect and reconnect the battery, you will need to reset some features.
