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 114). 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:

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
could 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
could decrease about
3 psi (21 kPa) for a
drop of 30°F (17°C) in ambient
temperature. This lower pressure value
could 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 WARNING:
If the tire pressure
monitor sensor becomes damaged it
may not function.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
Note: The tire pressure monitoring system
indicator light illuminates 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 this vehicle. If you get a flat tire when 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
system sensors.
See Tire Pressure
Monitoring System (page 368). 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.
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.

App Permissions
App permissions are organized by groups.
You can grant these group permissions
individually. You can change a permission
group status any time when not driving, by
using the settings menu.
When you launch an app using SYNC, the
system may ask you to grant certain
permissions, for example:
•
To allow your vehicle to provide vehicle
information to the app such as, but not
limited to: Fuel level, fuel economy, fuel
consumption, engine speed, rain
sensor, odometer, VIN, external
temperature, gear position, tire
pressure, and head lamp status.
• To allow your vehicle to provide driving
characteristic information such as, but
not limited to: MyKey, seat belt status,
engine revolutions per minute, gear
position, braking events, steering wheel
angle, and accelerator pedal position.
• To allow your vehicle to provide
location information, including: GPS
and speed.
• To allow the app to send push
notifications using the vehicle display
and voice capabilities while running in
a background state. Push notifications
may be particularly useful for news or
location based apps.
Note: You only need to grant permissions
the first time you use an app with SYNC.
Note: Ford is not responsible or liable for
any damages or loss of privacy relating to
usage of an app, or dissemination of any
vehicle data that you approve Ford to
provide to an app. Enabling SYNC Mobile Apps

through the connected device. The
information is encrypted and includes your
VIN, SYNC module number, anonymous
usage statistics and debugging
information. Updates may take place.
Note:
You must enable mobile apps for
