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: If your vehicle is equipped with the tire pressure monitoring
system (TPMS), the 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.

If your vehicle is equipped with TPMS, have a flat serviced by an
authorized dealer in order to prevent damage to the TPMS sensors, refer
to Tire pressure monitoring system (TPMS) in the Tires, Wheels and
Loading chapter. 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.

Roadside Emergencies

225

WARNING: The use of tire sealants may damage your tire
pressure monitoring system (TPMS) and should not be used.

However, if you must use a sealant, the TPMS sensor and valve stem
on the wheel must be replaced by an authorized Ford dealer.

WARNING: Refer to Tire pressure monitoring system (TPMS)
in the Tires, Wheels and Loading chapter 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 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

Roadside Emergencies

226

• 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
• All-wheel driving capability (if applicable)
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
(113 km/h). It is intended for temporary use only. This means if you
need to use it, you should replace it as soon as possible.

Stopping and securing your vehicle

1. Park on a level surface.

2. Activate the warning flashers.

3. Place the gearshift in P (Park).

4. Apply the parking brake and turn
the engine off.

Spare tire information

The spare tire for your vehicle is stowed under the rear of your vehicle
(except cutaway and stripped chassis models).

To remove the spare tire:

1. Open the rear doors and remove
the thumb screw and anti-theft
bracket. If finger pressure will not
remove the thumb screw, use the
lug wrench to loosen the screw.

2. Remove the access plug under
the left door.
