TIRE PRESSURE MONITORING SYSTEM
WARNING:The tire pressure monitoring system is not a
substitute for manually checking tire pressure. The tire pressure
should be checked periodically (at least monthly) using a tire gauge.
SeeInflating Your Tiresin this chapter. Failure to properly maintain
your tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire
inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-inflated. When the
low tire pressure telltale illuminates, you should stop and check your
tires as soon as possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and stopping ability.
The tire pressure monitoring system is not a substitute for proper tire
maintenance, and 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 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 system 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 system
malfunction telltale after replacing one or more tires or wheels on your

vehicle to ensure that the replacement or alternate tires and wheels
allow the system to continue to function properly.
The tire pressure monitoring system complies with part 15 of the FCC
rules and with RSS-210 of Industry Canada. Operation is subject to the
following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
Changing Tires with a Tire Pressure Monitoring System
Note:Each road tire is equipped
with a tire pressure sensor located
inside the tire and wheel 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. SeeInflating Your Tiresin 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.
When your temporary spare tire is installed
When one of your road tires needs to be replaced with the temporary
spare, the tire pressure monitoring system will continue to identify an
issue to remind you that the damaged road wheel or tire 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 or tire 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

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 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 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 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.

Tire Pressure Monitoring System Reset Procedure
WARNING:To determine the required pressure(s) for your
vehicle, see 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. SeeLoad
Carryingfor more information.
Note:The tire pressure monitoring system reset procedure needs to be
performed after each tire rotation on vehicles that require different
recommended tire pressures in the front tires as compared to the rear
tires.
Overview
To provide the vehicle’s load carrying capability, some vehicles require
different recommended tire pressures in the front tires as compared to
the rear tires. The tire pressure monitoring system equipped on these
vehicles is designed to illuminate the low tire pressure warning light at
two different pressures; one for the front tires and one for the rear tires.
Since tires need to be rotated to provide consistent performance and
maximum tire life, the tire pressure monitoring system needs to know
when the tires are rotated to determine which set of tires are on the
front and which are on the rear. With this information, the system can
detect and properly warn of low tire pressures.
System reset tips:
•To reduce the chances of interference from another vehicle, the
system reset procedure should be performed at least three feet (one
meter) away from another Ford Motor Company vehicle undergoing
the system reset procedure at the same time.
•Do not wait more than two minutes between resetting each tire sensor
or the system will time-out and the entire procedure will have to be
repeated on all four wheels.
•A double horn chirp indicates the need to repeat the procedure.

Performing the System Reset Procedure
Read the entire procedure before attempting.
1. Drive the vehicle above 20 mph (32 km/h) for at least two minutes
and 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. This must be
accomplished 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 equipped). If this does not occur, please try again
startingatStep2.
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 (if equipped), seek service from your authorized dealer.
5.Note: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 clockwise order:
•Left front (Driver’s side front tire)
•Right front (Passenger’s side front tire)
•Right rear (Passenger’s side rear tire)
•Left rear (Driver’s side rear 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 must be repeated.
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 rear tire;
decrease the air pressure until the horn sounds.
9. Remove the valve cap from the valve stem on the left rear tire;
decrease the air pressure until the horn sounds.
Training is complete after the horn sounds for the last tire trained
(driver’s side rear tire), the system indicator stops flashing, and a
message is shown in the information display (if equipped).

10. Turn the ignition off. If two short horn beeps are heard, the reset
procedure was unsuccessful and must be repeated.
If after repeating the procedure and two short beeps are heard when the
ignition is turned to off, seek assistance from your authorized dealer.
11. 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. SeeLoad Carryingfor more
information.
CHANGING A ROAD WHEEL
WARNING:The use of tire sealants may damage your tire
pressure monitoring system and should not be used. However, if
you must use a sealant, the tire pressure monitoring system sensor and
valve stem on the wheel must be replaced by an authorized Ford
dealer.
WARNING:SeeTire Pressure Monitoring Systemin this
chapter for important information. If the tire pressure monitor
sensor becomes damaged, it will no longer 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.
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. SeeTire Pressure Monitoring Systemin this
chapter. 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.
