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.

Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare tire is in use. To restore the full functionality
of the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat serviced by an authorized dealer in order to prevent damage
to the TPMS sensors, refer toTire pressure monitoring system
(TPMS)in theTires, Wheels and Loadingchapter. Replace the spare
tire with a road tire as soon as possible. During repairing or replacing of
the flat tire, have the authorized dealer inspect the TPMS sensor for
damage.
WARNING:The use of tire sealants may damage your Tire
Pressure Monitoring System and should not be used.
WARNING:Refer toTire pressure monitoring system (TPMS)
in theTires, Wheels and Loadingchapter for important
information. If the tire pressure monitor sensor becomes damaged, it
will no longer function.
Dissimilar spare tire/wheel information
WARNING:Failure to follow these guidelines could result in an
increased risk of loss of vehicle control, injury or death.
If you have a dissimilar spare tire/wheel, then it is intended for
temporary use only. This means that if you need to use it, you should
replace it as soon as possible with a road tire/wheel that is the same size
and type as the road tires and wheels that were originally provided by
Ford. If the dissimilar spare tire or wheel is damaged, it should be
replaced rather than repaired.
A dissimilar spare tire/wheel is defined as a spare tire and/or wheel that
is different in brand, size or appearance from the road tires and wheels
and can be one of three types:
1.T-type mini-spare:This spare tire begins with the letter “T” for tire
size and may have “Temporary Use Only” molded in the sidewall
2.Full-size dissimilar spare with label on wheel:This spare tire has
a label on the wheel that states: “THIS TIRE AND WHEEL FOR
TEMPORARY USE ONLY”

When driving with the full-size dissimilar spare tire/wheel additional
caution should be given to:
•Towing a trailer
•Driving vehicles equipped with a camper body
•Driving vehicles with a load on the cargo rack
Drive cautiously when using a full-size dissimilar spare tire/wheel and
seek service as soon as possible.
Stopping and securing the vehicle
1. Park on a level surface, activate
hazard flashers and set the parking
brake.
2. Place the gearshift lever in P
(Park) and turn the engine off.
Removing the spare tire and jack
1. Lift the carpeted load floor panel
located in the rear of the vehicle.
2. Remove the spare tire cover (if
equipped).
3. Remove the wing nut securing
the spare tire by turning it
counterclockwise.
4. Remove the plastic washer.
5. Lift and remove the temporary
spare tire from the cargo area.
6. Remove the jack assembly from
the vehicle. Loosen the bag tabs and
remove the jack and lug wrench
from the bag.
7. Fold down the wrench socket
used to loosen the lug nuts and
operate the jack.

Tire change procedure
WARNING:When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the vehicle is in P (Park).
WARNING:To help prevent the vehicle from moving when you
change a tire, be sure to place the transmission in P (Park), set
the parking brake and block (in both directions) the wheel that is
diagonally opposite (other side and end of the vehicle) to the tire
being changed.
WARNING:If the vehicle slips off the jack, you or someone else
could be seriously injured.
WARNING:Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack or changing the
wheel.
1. Block the diagonally opposite
wheel.
2. Remove wheel cover (if
equipped) with the lug wrench tip
and loosen each wheel lug nut
one-half turn counterclockwise but
do not remove them until the wheel
is raised off the ground.

WARNING: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.
3. Align the slot on top of the jack
with the sheet metal flange
indicated by the jack locator triangle
next to the tire you are changing.
Turn the jack handle clockwise until
the wheel is completely off the
ground.
4. Remove the lug nuts with the lug
wrench.
5. Replace the flat tire with the
spare tire, making sure the valve
stem is facing outward. 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.
6. Lower the wheel by turning the
jack handle counterclockwise.
7. Remove the jack and fully tighten
the lug nuts in the order shown.
Refer toWheel lug nut torque
specificationslater in this chapter
for the proper lug nut torque
specification.
Stowing the flat/spare tire and jack
1. Fully collapse the jack, fold the wrench socket into the handle and
place them both into the bag making sure to secure the tabs.

2. Place the jack assembly in the spare tire well aligning it with the two
vertical studs.
3. Place the tire in the spare tire well over the jack assembly.
If you are stowing a flat 22 inch tire and wheel assembly,
temporarily remove the load floor, plastic stowage bins, and the foam
load floor supports to make space for the 22 inch tire and wheel
assembly. Place the 22 inch tire & wheel assembly in the spare tire well
with the valve stem facing down. Rotate the tire until the jack assembly
is able to protrude through a wheel opening. Replace the plastic stowage
bins and foam supports around the 22 inch tire and wheel assembly and
then replace the load floor.
If you are stowing a flat tire,place the tire in the spare tire well with
the valve stem facing down. Rotate the tire until the jack assembly is
able to protrude through a wheel opening.
If you are stowing the spare tire,place the spare in the spare tire
well in its original position.
4. Secure the wheel by replacing the washer and the wing nut and
turning the wing nut clockwise.
WHEEL LUG NUT TORQUE SPECIFICATIONS
Retighten the lug nuts to the specified torque within 100 miles (160 km)
after any wheel disturbance (rotation, flat tire, wheel removal, etc.).

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.

Note: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 lugnut/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.
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 vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
