FORD 2013 Fusion Hybrid v.2 - Manual (Page 284)

Please note that the tire pressure
monitoring system is not a substitute for
proper tire maintenance. It is the driver’s
responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the tire pressure monitoring system low
tire pressure telltale.
Your vehicle has also been equipped with
a tire pressure monitoring system
malfunction indicator to indicate when the
system is not operating properly. The
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated. This
sequence will continue upon subsequent
vehicle start-ups as long as the
malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. System malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the system from functioning properly.
Always check the tire pressure monitoring
system malfunction telltale after replacing
one or more tires or wheels on your vehicle
to make sure that the replacement or
alternate tires and wheels allow the
system to continue to function properly.
Changing Tires with a Tire
Pressure Monitoring System
E142549
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. Care
must be taken when changing the tire to
avoid damaging the sensor
It is recommended that you always have
your tires serviced by an authorized dealer.
The tire pressure should be checked
periodically (at least monthly) using an
accurate tire gauge. See Inflating your tires
in this chapter.
Understanding Your Tire Pressure
Monitoring System
The tire pressure monitoring system
measures pressure in your four road tires
and sends the tire pressure readings to
your vehicle. 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.
