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 114). 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 131).

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 114). Performing the
trailer setup process also resets the trailer
tire pressure monitoring system.

CHANGING A ROAD WHEEL

WARNING

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

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.

Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.

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 400). 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.

Full-size dissimilar spare

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

When driving with the full-size dissimilar
spare wheel and tire assembly, it is
recommended that you do not:
•

Exceed 50 mph (80 km/h) in 4WD.

•

Engage 4WD unless the vehicle is
stationary.

•

Use 4WD on dry pavement.

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.

•

Four-wheel drive 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.

Drive cautiously when using a full-size
dissimilar spare wheel and tire assembly
and seek service as soon as possible.

Location of the Spare Tire and

E162800

4. Lift the spare tire on end to access the

6. If not replacing the spare or flat tire to

the underbody storage area, raise the
wheel retainer up into the installed
position.

7.

Use the attached fastener strap (on
the spare tire tether) to attach the
tether end to the winch retainer prior
to raising to the installed position.
