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.
Always disconnect the battery before servicing high current
fuses.
To reduce risk of electrical shock, 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
Batterysection of theMaintenance and Specificationschapter.
The high-current fuses are coded as follows:

Tire change procedure
To help prevent the vehicle from moving when you change a tire,
be sure the parking brake is set, then block the wheels (both
front or both rear) on the opposite end of the vehicle from the wheel
being changed. If on a grade, block both opposite wheels on the
downward side of the hill.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
On vehicles equipped with Air Suspension, turn OFF the Air
Suspension system prior to jacking, hoisting or towing your
vehicle.
If your vehicle is equipped with air suspension, refer toMessage center
in theDriver Controlschapter for instructions on turning the air
suspension system off.
Refer to the instruction sheet (located in the rear floor compartment
behind the 3rd row seat with the jack tray tools assembly kit) for
detailed tire change instructions.
1. Park on a level surface, activate
hazard flashers and set the parking
brake.
