Performing the System Reset Procedure
(Dual Rear Wheel)

For further information see
Understanding Your Tire Pressure
Monitoring System and refer to Dual
Rear Wheel, earlier in this section.

Read the entire procedure before
attempting.

1.

Drive the vehicle above 20 mph
(32 km/h) for at least two minutes,
then park in a safe location where you
can easily get to all four tires and have
access to an air pump.

2. Place the ignition in the off position and

keep the key in the ignition.

3. Cycle the ignition to the on position

with the engine off.

4. Turn the hazard flashers on then off

three times. You must accomplish this
within 10 seconds. If the reset mode
has been entered successfully, the horn
will sound once, the system indicator
will flash and a message is shown in
the information display. If this does not
occur, please try again starting at Step
2. If after repeated attempts to enter
the reset mode, the horn does not
sound, the system indicator does not
flash and no message is shown in the
information display, seek service from
your authorized dealer.

5. Train the tire pressure monitoring

system sensors in the tires using the
following system reset sequence
starting with the left front tire in the
following order: Left front (driver's side
front tire), Right front (passenger's side
front tire), Right outer rear (passenger's
side rear outer tire), Right inner rear
(passenger's side rear inner tire), Left
outer rear (driver's side rear outer tire),
Left inner rear (driver's side rear inner
tire).

6. Remove the valve cap from the valve

stem on the left front tire. Decrease the
air pressure until the horn sounds.

Note: The single horn chirp confirms that
the sensor identification code has been
learned by the module for this position. If a
double horn is heard, the reset procedure
was unsuccessful, and you must repeat it.

7.

Remove the valve cap from the valve
stem on the right front tire. Decrease
the air pressure until the horn sounds.

8. Remove the valve cap from the valve

stem on the right outer rear tire.
Decrease the air pressure until the horn
sounds.

9. Remove the valve cap from the valve

stem on the right inner rear tire.
Decrease the air pressure until the horn
sounds.

10.

Remove the valve cap from the valve
stem on the left outer rear tire.
Decrease the air pressure until the
horn sounds.

11.

Remove the valve cap from the valve
stem on the left inner rear tire.
Decrease the air pressure until the
horn sounds. Training is complete
after the horn sounds for the last tire
trained, the system indicator stops
flashing, and a message is shown in
the information display.

12.

Turn the ignition off. If two short horn
beeps are heard, the reset procedure
was unsuccessful and you must
repeat it. If after repeating the
procedure and two short beeps are
heard when the ignition is turned to
off, seek assistance from your
authorized dealer.

13.

Set all four tires to the recommended
air pressure as indicated on the
Safety Compliance Certification
Label (affixed to either the door hinge
pillar, door-latch post, or the door
edge that meets the door-latch post,
next to the driver's seating position)
or Tire Label located on the B-Pillar
or the edge of the driver's door.

Trailer Tire Pressure Monitoring
System

(If Equipped)

Note: Additional equipment may be
required for your vehicle to support trailer
tire pressure monitoring. See your authorized
dealer for more information.

Note: The trailer tire pressure monitoring
system is not a substitute for proper tire
maintenance. It is your responsibility to
maintain correct tire pressures at all times.

Note: If a trailer tire is repaired, replaced or
broken down for service, the screw and valve
on the trailer tire pressure sensor should be
replaced. See your authorized dealer for
details.

E235807

The trailer tire pressure monitoring system
is an added safety feature that allows you
to view your trailer tire pressures through
the information display. See General
Information (page 111). Tire pressure
sensors are mounted into each tire on your
trailer. The sensors send a message to your
vehicle indicating the current trailer tire
pressure.

If the trailer tire pressure monitoring
system detects that a tire is low, a warning
message appears in the information
display. The trailer tire pressure status
screen in the information display highlights
the tire with a low pressure.

The main function of the trailer tire
pressure monitoring system is to warn you
when your trailer tires need air. It can also
warn you in the event the system is no
longer capable of functioning as intended.
See Information Messages (page 128).

When a Temporary Spare or New Tire
is Installed

If you have replaced a trailer tire with a new
or spare tire, a warning message appears
and pressure readings are no longer
displayed for that tire.

To restore the full function of the trailer
tire pressure monitoring system:
•

Have the damaged wheel and tire
assembly repaired and remounted to
your trailer.

•

Install the trailer tire pressure
monitoring sensor into the new wheel
and tire assembly.

•

Perform the trailer tire pressure
monitoring system reset procedure.

Trailer Tire Pressure Monitoring
System Reset Procedure

Note: You need to perform the tire pressure
monitoring system reset procedure after
each tire rotation, or when a new trailer tire
pressure sensor is installed into a trailer tire.

The trailer tire pressure monitoring system
can be reset through the menu in the
information display. See General
Information (page 111). Performing the
trailer setup process also resets the trailer
tire pressure monitoring system.

CHANGING A ROAD WHEEL

WARNINGS

The use of tire sealant may damage
your tire pressure monitoring system
and should only be used in roadside

emergencies. If you must use a sealant, the
Ford Tire Mobility Kit sealant should be
used. The tire pressure monitoring system
sensor and valve stem on the wheel must
be replaced by an authorized dealer after
use of the sealant.

If the tire pressure monitor sensor
becomes damaged, it will no longer
function. See Tire Pressure

Monitoring System (page 390).

Note: If your vehicle is equipped with the
tire pressure monitoring system, the
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.

If your vehicle is equipped with the tire
pressure monitoring system, have a flat
serviced by an authorized dealer in order
to prevent damage to the system sensors.
See Tire Pressure Monitoring System
(page 390). 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 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
