Tire pressure monitoring system

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 about 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 about 3 psi (21 kPa) for a drop of30°F (17°C) in ambient temperature. This
lower pressure value may 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.
Tire Pressure Monitoring System Reset
Procedure
WARNING
To determine the required pressure(s)
for your vehicle, see the Safety
Compliance Certification Label (on the door
hinge pillar, door-latch post or the door edge
that meets the door-latch post, next to the
driver seat) or the Tire Label on the B-Pillar
or the edge of the driver door. Note:
You need to perform the tire pressure
monitoring system reset procedure 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, perform the system
reset procedure 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 will sound indicating 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, 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. You must accomplish this 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 this does not occur, please try
again starting at Step 2. 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, seek
service from your authorized dealer.
5. 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 you must repeat it.
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.
10. Turn the ignition off. If two short horn beeps are heard, the reset procedure
was unsuccessful and you must repeat
it. 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.
CHANGING A ROAD WHEEL WARNINGS
The use of tire sealant may damage
your tire pressure monitoring system
and should only be used in roadside
emergencies. If you must use a sealant, the
Ford Tire Mobility Kit sealant should be used.
The tire pressure monitoring system sensor
and valve stem on the wheel must be
replaced by an authorized dealer after use
of the sealant. If the tire pressure monitor sensor
becomes damaged, it will no longer
function. See Tire Pressure Monitoring
System (page 313). 319

Note:
The tire pressure monitoring system
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 this 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.
Have a flat serviced by an authorized dealer
in order to prevent damage to the system
sensors See Tire Pressure Monitoring
System (page 313). 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.
