13. Insert the jack handle into the
pump linkage.
14. Use an up-and-down motion
with the jack handle to raise the
wheel completely off the ground.
Hydraulic jacks are equipped
with a pressure release valve
that prevents lifting loads which
exceed the jack’s rated capacity. Roadside Emergencies

15. Remove the lug nuts with the lug wrench.
16. Replace the flat tire with the spare tire, making sure the valve stem
is facing outward on all front an inboard rear wheels. 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.
17. Lower the wheel by slowly turning the release valve
counterclockwise. Opening the release valve slowly will provide a more
controlled rate of descent.
The following steps apply to all vehicles:
18. Remove the jack and fully
tighten the lug nuts in the order
shown. Refer to Wheel lug nut
torque specifications later in this
chapter for the proper lug nut
torque specification.

19. Stow the flat tire. Refer to Stowing the flat/spare tire if the vehicle
is equipped with a spare tire carrier.
20. Stow the jack, jack handle and lug wrench. Make sure the jack is
securely fastened so it does not rattle when driving.
21. Unblock the wheels.
The following step applies to F–250/F–350 Single Rear Wheel
(SRW) vehicles only:
22. When installing the wheel center
ornaments, ensure that the
ornament retention towers on the
back side of the ornament are
aligned with the studs/lug nuts. The
retention towers are designed to be
installed over the studs/nuts and
retain to the flange on the lug nut. Roadside Emergencies

If the ornament retention towers are
aligned between the studs/lug nuts,
the ornament is improperly
installed. This improper installation
may appear and sound correct, but
will not keep the ornament on the
vehicle. Ornaments improperly
installed in this manner will fall off
or become loose with minimal force
or impact.
Installing dual rear wheel ornaments
1. Align the ornament with the lug
nuts.
• (1) is the clip and (2) is the
flange.
2. Hold the ornament so that all of
the retention clips are sitting on the
flange of the lug nuts.
3. Use your hand or rubber mallet to
tap the ornament in a star pattern.
There should be an even gap
between the ornament and the
wheel. 1 2Roadside Emergencies

4. Be sure to install all the clips on the nuts over the flanges so that
there is an even gap all around and the retention clips are fully seated.
Stowing the flat/spare tire
Note: Failure to follow spare tire stowage instructions may result in
failure of cable or loss of spare tire.
If you are stowing a tire that requires reattaching it to the
vehicle with a tether, perform these steps first, then proceed with
the steps following.
1. Place the tire on end with the
valve stem facing toward the front
of the vehicle.
2. Place the tether into the bolt
holes in the wheel and attach the
lug nut using the lug winch.
3. Lay the tire on the ground with the valve stem facing in the direction
specified on the tire changing instructions located with the jack and
tools. Roadside Emergencies

4. Slide the wheel partially under the vehicle and install the retainer
through the wheel center. Pull on the cable to align the components at
the end of the cable.
5. Turn the jack handle clockwise until the tire is raised to its stowed
position underneath the vehicle. The effort to turn the jack handle
increases significantly and the spare tire carrier ratchets or slips when
the tire is raised to the maximum tightness. Tighten to the best of your
ability, to the point where the ratchet/slip occurs, if possible. The spare
tire carrier will not allow you to overtighten. If the spare tire carrier
ratchets or slips with little effort, take the vehicle to your authorized
dealer for assistance at your earliest convenience.
6. Check that the tire lies flat against the frame and is properly
tightened. Try to push or pull, then turn the tire to be sure it will not
move. Loosen and retighten, if necessary. Failure to properly stow the
spare tire may result in failure of the winch cable and loss of the tire.
7. Repeat this tightness check procedure when servicing the spare tire
pressure (every six months, per scheduled maintenance information),
or at any time that the spare tire is disturbed through service of other
components.
8. If removed, install the spare tire lock (if equipped) into the bumper
drive tube with the spare tire lock key (if equipped) and jack handle.
WHEEL LUG NUT TORQUE SPECIFICATIONS
On vehicles equipped with single rear wheels, retighten the lug nuts to
the specified torque at 500 miles (800 km) after any wheel disturbance
(tire rotation, changing a flat tire, wheel removal, etc.).
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts
to the specified torque at 100 miles (160 km), and again at 500 miles
(800 km) of new vehicle operation and after any wheel disturbance (tire
rotation, changing a flat tire, wheel removal, etc.).

On all two-piece flat wheel nuts,
apply one drop of motor oil between
the flat washer and the nut.
WARNING: When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake drum or
brake disc that contacts the wheel. Ensure that any fasteners that
attach the rotor to the hub are secured so they do not interfere with
the mounting surfaces of the wheel. Installing wheels without correct
metal-to-metal contact at the wheel mounting surfaces can cause the
wheel nuts to loosen and the wheel to come off while the vehicle is in
motion, resulting in loss of control.
Inspect the wheel pilot hole prior to
installation. If there is visible
corrosion in wheel pilot hole,
remove loose particles by wiping
with clean rag and apply grease.
Apply grease only to the wheel pilot
hole surface by smearing a “dime”
(1 square cm) sized glob of grease
around the wheel pilot surface (1)
with end of finger. DO NOT apply
grease to lug nut/stud holes or
wheel-to-brake surfaces.
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. Roadside Emergencies

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.
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 vehicles do not touch. 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.
