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

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.
Stopping and securing the vehicle
1. Park on a level surface, set the
parking brake and activate hazard
flashers.
2. Place gearshift lever in P (Park)
and turn engine off.

4. Remove the lug nuts with the lug nut wrench.
5. Replace the flat tire with the spare tire, 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.
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 jack and tools
•Make sure the jack is fully
lowered.
•Reclip the tools onto the jack
making sure that the tools are
fully contained by the clips as
shown.
•Reinstall the jack in the pocket
with the left side first, then snap
the right side down.
•Ensure that the hold-strap
contains the jack and tools before snapping the buckle.
•Ensure that the jack and tools are oriented as illustrated.
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 tire on end with valve stem
facing rearward, away from vehicle.
2. Place tether into bolt holes in
wheel and attach lug nut using lug
wrench.
3. Lay the tire on the ground with the valve stem facing down. If your
vehicle is equipped with aluminum wheels, remove the wheel ornament.
4. Slide the wheel partially under the vehicle and install the retainer
through the center of the wheel.
5. Turn the jack handle clockwise until the tire is raised to its original
position underneath the vehicle. The effort to turn the jack handle
increases significantly as the tire contacts the frame. The spare tire
carrier will ratchet when the tire is in the fully stowed position. The
spare tire carrier has a built-in ratchet feature that will not allow you to
overtighten. If the spare tire carrier ratchets with very little effort, take
the vehicle to your authorized dealer for assistance at your earliest
convenience.If your vehicle is equipped with a trailer hitch, guide
the tire with one hand; keep the rear of the tire tilted down until
the tire clears the bumper.
6. Check that the tire lies flat against the frame assembly. Push against
the tire to make sure it is tightly seated under the vehicle. Loosen and
retighten, if necessary. Failure to properly stow the spare tire may result
in failure of the winch cable and loss of the spare tire.(Make sure that
the tire does not contact the bumper.)
7. Repeat this tightness check procedure (every six months, per
scheduled maintenance information),when servicing the spare tire
pressure or at any time that the spare tire is disturbed through service of
other components.

WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
It is recommended that your vehicle be towed with a wheel lift and
dollies or flatbed equipment. Do not tow with a slingbelt. Ford Motor
Company has not approved a slingbelt towing procedure.
On FWD vehicles, if your vehicle is to be towed from the front, ensure
proper wheel lift equipment is used to raise the front wheels off the
ground. The rear wheels can be left on the ground when towed in this
fashion.
If your vehicle is to be towed from the rear using wheel lift equipment, it
isrequiredthat the front wheels (drive wheels) be placed on a dolly to
prevent damage to the automatic transaxle.
On 4WD vehicles, it isrequiredthat your vehicle be towed with a wheel
lift and dollies or flatbed equipment with all the wheels off the ground to
prevent damage to the automatic transaxle, 4WD system or vehicle.

Ford Motor Company produces a towing manual for all authorized tow
truck operators. Have your tow truck operator refer to this manual for
proper hook-up and towing procedures for your vehicle.
If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
Emergency Towing
In case of a roadside emergency with a disabled vehicle (without access
to wheel dollies, car hauling trailer, or flatbed transport vehicle) your
vehicle (regardless of transmission powertrain configuration) can be flat
towed (all wheels on the ground) under the following conditions:
•Vehicle is facing forward.
•Place the transmission in N (Neutral).
•Maximum speed is not to exceed 35 mph (56 km/h).
