Power distribution box
The power distribution box, trailer tow and electronic shift on the fly
relay blocks are located in the engine compartment near the brake
master cylinder.
The power distribution box contains high-current fuses that protect your
vehicle’s main electrical systems from overloads.
Always disconnect the battery before servicing high current
fuses.
Always replace the cover to the Power Distribution Box before
reconnecting the battery or refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Battery
section of the
Maintenance and Care
chapter.
