CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
Your vehicle may be equipped with a conventional spare tire that is
different in one or more of the following: type, brand, size, speed rating
and tread design. If this is the case, this dissimilar spare tire is still rated
for your vehicle loads (GAWR and GVWR). This temporary spare tire is
not equipped with a Tire Pressure Monitor System (TPMS) sensor.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare is in use. To restore the full functionality of
the TPMS system, all road wheels equipped with the tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat tire serviced by an authorized dealer in order to prevent
damage to the TPMS sensor, 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.
The use of tire sealants may damage your Tire Pressure
Monitoring System and should not be used.

Refer toTire Pressure Monitoring System (TPMS)in theTire,
Wheels and Loadingchapter for important information. If the
tire pressure monitor sensor becomes damaged, it will no longer
function.
Dissimilar spare tire/wheel information
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 one of the dissimilar spare tires listed above,do not:
•Exceed 50 mph (80 km/h)
•Load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
•Tow a trailer
•Use snow chains on the end of the vehicle with the dissimilar spare
tire
•Use more than one dissimilar spare tire at a time
•Use commercial car washing equipment
•Try to repair the dissimilar spare tire
Use of one of the dissimilar spare tires listed above at any one wheel
location can lead to impairment of the following:
•Handling, stability and braking performance

•Comfort and noise
•Ground clearance and parking at curbs
•Winter weather driving capability
•Wet weather driving capability
For vehicles equipped with 4WD, it is not recommended that the vehicle
be operated in 4WD modes with a temporary emergency spare tire. If
4WD operation is necessary, do not operate above speeds of 10 mph
(16 km/h) or for distances above 50 miles (80 km).
3.Full-size dissimilar spare without label on wheel
When driving with the full-size dissimilar spare tire/wheel,do not:
•Exceed 70 mph (113 km/h)
•Use more than one dissimilar spare tire/wheel at a time
•Use commercial car washing equipment
•Use snow chains on the end of the vehicle with the dissimilar spare
tire/wheel
The usage of a full-size dissimilar spare tire/wheel can lead to
impairment of the following:
•Handling, stability and braking performance
•Comfort and noise
•Ground clearance and parking at curbs
•Winter weather driving capability
•Wet weather driving capability
•All-Wheel driving capability (if applicable)
•Load leveling adjustment (if applicable)
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.
Full-size Matching Spare Tire/Wheel Information
This spare tire/wheel will match the road tire/wheel. When driving with
the full size matching spare tire/wheel, do not exceed 70 mph

2. Remove the lug wrench from the
jack. Rotate the lug wrench socket
out from the handle.
Tire change procedure
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).
To help 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.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
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.

ornament from the aluminum wheel
with the tapered end of the wheel
nut wrench that came with your
vehicle. Insert and twist the handle,
then pry against the wheel.
3. If equipped with a full
wheelcover, remove the wheelcover
center ornament then loosen the five black plastic nuts which retain the
wheelcover using the lug wrench.
4. Loosen each wheel metal lug nut one-half turn counterclockwise but
do not remove them until the wheel is raised off the ground.
Before placing the jack under the vehicle, NOTE the jack location
markings:

To lessen 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.
•Never use the rear differential
as a jacking point.
5. Remove the metal lug nuts with the lug wrench.
6. Replace the flat tire/wheel assembly with the spare tire/wheel
assembly, making sure the valve stem is facing outward. Reinstall lug
nuts until the wheel is snug against the hub. Do not fully tighten the lug
nuts until the wheel has been lowered.
7. Lower the vehicle by turning the jack handle counterclockwise.
8. 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.
9. For full size spare aluminum
wheel, firmly install the center
ornament. If equipped with a full
size spare tire/wheel assembly and
lug nut retained full wheelcover, install the wheelcover by tightening the
five black plastic nuts in the order shown on the wheelcover using the
lug wrench with about 80 lb. in. (9 N•m) torque. Then firmly install the
wheelcover center ornament.
10. Put flat tire, jack and lug wrench away.
11. Turn on the air suspension switch (if equipped).

* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
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
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.
