F53 Power Distribution Box
 WARNING: Always disconnect the battery before servicing high current fuses. WARNING: To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs. |
Locate the power distribution box in the engine compartment. It has high-current fuses that protect your vehicle’s main electrical systems from overloads.If the battery has been disconnected and reconnected, you will need to reset some features.
