Low tire pressure
warning lightPossible cause Customer action required
Flashing warning
lightSpare tire in use Your temporary spare tire is in
use. Repair the damaged road
wheel and re-mount it on the
vehicle to restore system
functionality. For a description
of how the system functions
under these conditions, refer to
When your temporary spare
tire is installedin this section.
TPMS
malfunctionIf your tires are properly
inflated and your spare tire is
not in use and the TPMS
warning light still flashes,
contact your authorized dealer
as soon as possible.
When inflating your tires
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 (TPMS) monitors tire pressure in
each pneumatic tire. While driving in a normal manner, a typical
passenger tire inflation pressure may increase approximately 2 to 4 psi
(14 to 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 approximately 3 psi
(21 kPa) for a drop of 30°F (17°C) in ambient temperature. This lower
pressure value may be detected by the TPMS as being significantly lower
than the recommended inflation pressure and activate the TPMS 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 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 THE TIRES
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.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare tire is in use. To restore the full functionality
of the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat serviced by an authorized dealer in order to prevent damage
to the TPMS sensors, refer toTire pressure monitoring system
(TPMS)in theTires, Wheels and Loadingchapter. 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 TPMS sensor for
damage.
WARNING:The use of tire sealants may damage your tire
pressure monitoring system (TPMS) and should not be used.
However, if you must use a sealant, the TPMS sensor and valve stem
on the wheel must be replaced by an authorized Ford dealer.
WARNING:Refer toTire pressure monitoring system (TPMS)
in theTires, Wheels and Loadingchapter for important
information. If the tire pressure monitor sensor becomes damaged, it
will no longer function.
Dissimilar spare tire/wheel 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 tire/wheel, 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 tire/wheel 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.
