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 the battery has been disconnected and reconnected, refer to the
Batterysection of theMaintenance and Specificationschapter.
The high-current fuses are coded as follows:

RUNNING OUT OF FUEL
If you have run out of fuel and need to refill the vehicle with a portable
fuel container, seeRunning out of fuelin theMaintenance and
Specificationschapter for proper fuel filling method using a portable
fuel container and the included fuel filler funnel.Do notinsert the
nozzle of portable fuel containers or any type of aftermarket funnels into
the Easy Fuel™no capfuel system as it can be damaged. You must use
the included funnel in such circumstances.
WARNING:Do not insert the nozzle of portable fuel containers
or aftermarket funnels into the Easy Fuel™ system. This could
damage the fuel system and its seal, and may cause fuel to run onto
the ground instead of filling the tank, all of which could result in
serious personal injury.
JUMP STARTING
WARNING:The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING:Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission
vehicle. Automatic transmissions do not have push-start
capability. Attempting to push-start a vehicle with an automatic
transmission may cause transmission damage.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation.

damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.

bottle.Do notuse fuel lines, engine rocker covers or the intake manifold
asgroundingpoints.
WARNING:Do not connect the end of the second cable to the
negative (-) terminal of the battery to be jumped. A spark may
cause an explosion of the gases that surround the battery.
5. Ensure that the cables are clear of fan blades, belts, moving parts of
both engines, or any fuel delivery system parts.
Jump starting
1. Start the engine of the booster vehicle and run the engine at
moderately increased speed.
2. Start the engine of the disabled vehicle.
3. Once the disabled vehicle has been started, run both engines for an
additional three minutes before disconnecting the jumper cables.
