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
Batterysection of theMaintenance and carechapter.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Spare tire information
Your vehicle may be equipped with a spare tire that can be used as
either a spare or a regular tire. The spare tire is not equipped with wheel
trim. The wheel trim from the original wheel/tire may be used on the
spare.
If your vehicle is equipped with 4WD, a spare tire of a different
size than the road tires should not be used. Such a tire could
result in damage to driveline components and make the vehicle
difficult to control.
Location of the spare tire and tools
The spare tire and tools for your vehicle are stowed in the following
locations:
Tool Location
Spare tire
(pick-up trucks only)Under the vehicle, just forward of the rear
bumper
Jack Regular cab, crew cab and SuperCab
without rear bench seat: Fastened to floor
pan behind rearmost seat on passenger side
SuperCab with rear bench seat: Under rear
bench on passenger side
Jack handle and lug
wrenchOn top of the radiator support at the front
of the engine compartment
Key, spare tire lock
(if equipped)In the glove box
Removing the spare tire (with spare tire carrier only)
1. The following tools are required to remove the spare tire:
•one handle extension and one
typical extension. To assemble,
align button with hole and slide
parts together. To disconnect,
depress button and pull apart.

To prevent the vehicle from
moving when you change a
tire, be sure the parking brake is
set, then block (in both
directions) the wheel that is
diagonally opposite (other side
and end of the vehicle) to the tire
being changed.
2. Turn engine OFF and block the diagonally opposite wheel (block not
provided).
3. Remove the jack, jack handle, lug wrench and spare tire from the
stowage locations.
4. Use the tip of the lug wrench to remove any wheel trim.
5. Loosen each wheel lug nut
one-half turn counterclockwise but
do not remove them until the wheel
is raised off the ground.
When one of the rear wheels is off the ground, the transmission
alone will not prevent the vehicle from moving or slipping off the
jack, even if the transmission is in P (Park) (automatic transmission)
or R (Reverse) (manual transmission). To prevent the vehicle from
moving when you change the tire, be sure that the parking brake is set
and the diagonally opposite wheel is blocked.
If the vehicle slips off the jack, you or someone else could be
seriously injured.

Never use the front or rear
differential as a jacking point.
To lessen the risk of
personal injury, do not put
any part of your body under the
vehicle while changing a tire. Do
not start the engine when your
vehicle is on the jack. The jack is
only meant for changing the tire.
8. Turn the jack handle clockwise
until the wheel is completely off the
ground and high enough to install
the spare tire.
9. Remove the lug nuts with the lug
wrench.
10. On single rear wheel vehicles,
replace the flat tire with the spare
tire, making sure the valve stem is
facing outward for all front tires and
vehicles equipped with single rear
wheels. If replacing an inboard rear
tire on a dual rear wheel vehicle,
the valve stem must be facing outward. If replacing the outboard wheel,
the valve stem must be facing inward. Reinstall the lug nuts until the
wheel is snug against the hub. Do not fully tighten the lug nuts until the
wheel has been lowered.
11. Lower the wheel by turning the jack handle counterclockwise.
Go to step 19.

JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes, and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic conveter may become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. 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 to its
optimum shift feel.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
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 any electrical
surges. Turn all other accessories off.

3. Connect the negative (-) cable to the negative (-) terminal of the
assisting battery.
4. Make the final connection of the negative (-) cable to an exposed
metal part of the stalled vehicle’s engine, away from the battery and the
carburetor/fuel injection system.Do notuse fuel lines, engine rocker
covers or the intake manifold asgroundingpoints.
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.
Removing the jumper cables
Remove the jumper cables in the reverse order that they were
connected.
1. Remove the jumper cable from thegroundmetal surface.
Note:In the illustrations,lightning boltsare used to designate the
assisting (boosting) battery.
2. Remove the jumper cable on the negative (-) connection of the
booster vehicle’s battery.

3. Remove the jumper cable from the positive (+) terminal of the booster
vehicle’s battery.
4. Remove the jumper cable from the positive (+) terminal of the
disabled vehicle’s battery.
After the disabled vehicle has been started and the jumper cables
removed, allow it to idle for several minutes so the engine computer can
relearnits idle conditions.
When the battery is disconnected or a new battery is installed, the

transmission may shift firmly. This operation is considered normal and
will not effect function or durability of the transmission. Over time, the
