Changing Tires With a Tire
Pressure Monitoring System

Note: Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem. The
pressure sensor is covered by the tire and is
not visible unless the tire is removed. Take
care when changing the tire to avoid
damaging the sensor.

You should always have your tires serviced
by an authorized dealer.

Check the tire pressure periodically (at
least monthly) using an accurate tire
gauge. See When Inflating Your Tires in
this chapter.

Understanding Your Tire Pressure
Monitoring System

The tire pressure monitoring system
measures pressure in your road tires and
sends the tire pressure readings to your
vehicle. You can view the tire pressure
readings through the information display.
See General Information (page 104). The
low tire pressure warning light will turn on
if the tire pressure is significantly low. Once
the light is illuminated, your tires are
under-inflated and need to be inflated to
the manufacturer’s recommended tire
pressure. Even if the light turns on and a
short time later turns off, your tire pressure
still needs to be checked.

When Your Temporary Spare Tire is
Installed

When one of your road tires needs to be
replaced with the temporary spare, the
system will continue to identify an issue to
remind you that the damaged road wheel
and tire assembly needs to be repaired and
put back on your vehicle.

To restore the full function of the tire
pressure monitoring system, have the
damaged road wheel and tire assembly
repaired and remounted on your vehicle.

When You Believe Your System is Not
Operating Properly

The main function of the tire pressure
monitoring system is to warn you when
your tires need air. It can also warn you in
the event the system is no longer capable
of functioning as intended. See the
following chart for information concerning
your tire pressure monitoring system:

Make sure tires are at the proper pres-
sure. See Inflating your tires in this
chapter. After inflating your tires to the
manufacturer’s recommended pressure
as shown on the Tire Label (located on
the edge of driver’s door or the B-Pillar),
the vehicle must be driven for at least
two minutes over 20 mph (32 km/h)
before the light turns off.

If the tires are properly inflated and the
spare tire is not in use but the light
remains on, contact your authorized
dealer as soon as possible.

When Inflating Your Tires

WARNING

Do not use the tire pressure
displayed in the information display
as a tire pressure gauge. Failure to

follow this instruction could result in
personal injury or death.

When putting air into your tires (such as at
a gas station or in your garage), the tire
pressure monitoring system may not
respond immediately to the air added to
your tires.

It may take up to two minutes of driving
over 20 mph (32 km/h) for the light to turn
off after you have filled your tires to the
recommended inflation pressure.

How Temperature Affects Your Tire
Pressure

The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase about 2–4 psi (14–28 kPa)
from a cold start situation. If the vehicle is
stationary overnight with the outside
temperature significantly lower than the
daytime temperature, the tire pressure may
decrease about 3 psi (21 kPa) for a drop of
30°F (17°C) in ambient temperature. This
lower pressure value may be detected by
the tire pressure monitoring system as
being significantly lower than the
recommended inflation pressure and
activate the system warning light for low
tire pressure. If the low tire pressure
warning light is on, visually check each tire
to verify that no tire is flat. If one or more
tires are flat, repair as necessary. Check
the air pressure in the road tires. If any tire
is under-inflated, carefully drive the vehicle
to the nearest location where air can be
added to the tires. Inflate all the tires to
the recommended inflation pressure.

CHANGING A ROAD WHEEL

WARNINGS

Do not use tire sealants as they may
damage the tire pressure monitoring
system.

If the tire pressure monitor sensor
becomes damaged it may not
function.

Note: The tire pressure monitoring system
indicator light will illuminate when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.

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.

Have a flat serviced by an authorized
dealer in order to prevent damage to the
tire pressure monitoring system sensors.
See Tire Pressure Monitoring System
(page 326).  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 tire
pressure monitoring system sensor for
damage.

Dissimilar Spare Wheel and Tire
Assembly 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 wheel and
tire, 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 wheel and tire assembly 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 wheel and tire assembly
is defined as a spare wheel and tire
assembly 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 WHEEL AND
TIRE ASSEMBLY 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.

•

All-wheel driving capability.

3. Full-size dissimilar spare without
label on wheel

When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
•

Exceed 70 mph (113 km/h).

•

Use more than one dissimilar spare
wheel and tire assembly at a time.

•

Use commercial car washing
equipment.

•

Use snow chains on the end of the
vehicle with the dissimilar spare wheel
and tire assembly.

The usage of a full-size dissimilar spare
wheel and tire assembly 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.

When driving with the full-size dissimilar
spare wheel and tire assembly 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.
