Roadside Emergencies
Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle's main electrical systems from overloads.
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.
If your vehicle is equipped with an auxiliary battery,
disconnecting the primary under-hood battery DOES NOT remove
power from all circuits.
If the battery has been disconnected and reconnected, refer to the
Battery section of the Maintenance and Specifications chapter.
The high-current fuses are coded as follows.
