Recommended Tire Pressures
and Inflating Your Tires
Safe operation of your vehicle
requires that your tires are
properly inflated. Remember that
a tire can lose up to half of its air
pressure without appearing flat.
Every day before you drive, check
your tires. If one looks lower than
the others, use a tire gauge to
check the pressure of all tires and
adjust if required.
At least once a month and before
long trips, inspect each tire and
check the tire pressure with a tire
gauge (including spare, if
equipped). Inflate all tires to the
inflation pressure recommended
by the manufacturer. WARNING: Under-inflation
is the most common cause of
tire failures and may result in
severe tire cracking, tread
separation or blowout, with
unexpected loss of vehicle control and increased risk of
injury. Under-inflation increases
sidewall flexing and rolling
resistance, resulting in heat
buildup and internal damage to
the tire. It also may result in
unnecessary tire stress, irregular
wear, loss of vehicle control and
accidents. A tire can lose up to
half of its air pressure and not
appear to be flat!
You are strongly urged to buy a
reliable tire pressure gauge, as
automatic service station gauges
may be inaccurate. We
recommend the use of a digital or
dial-type tire pressure gauge
rather than a stick-type tire
pressure gauge. Use the
recommended cold inflation
pressure for optimum tire
performance and wear.
Under-inflation or over-inflation
may cause uneven treadwear
patterns.
Always inflate your tires to the
recommended inflation pressure
even if it is less than the maximum
inflation pressure information
found on the tire. You will find a
Tire Label containing the
manufactures recommended tire
inflation pressure by the tire size
and other important information
located on the B-Pillar or the edge
of the driver ’s door).

WARNING: Only use
replacement tires and wheels
that are the same size, load
index, speed rating and type
(such as P-metric versus
LT-metric or all-season versus
all-terrain) as those originally
provided by Ford. The
recommended tire and wheel
size may be found on either 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 the
Tire Label which is located on
the B-Pillar or edge of the
driver's door. If this information
is not found on these labels, then
you should contact your
authorized dealer as soon as
possible. Use of any tire or wheel
not recommended by Ford can
affect the safety and
performance of your vehicle,
which could result in an
increased risk of loss of vehicle
control, vehicle rollover, personal
injury and death. WARNING: To reduce the
risk of serious injury, when
mounting replacement tires and
wheels, you should not exceed
the maximum pressure indicated
on the sidewall of the tire to set
the beads without additional
precautions listed below. If the
beads do not seat at the
maximum pressure indicated,
re-lubricate and try again. WARNING: For a mounting
pressure more than
20 psi
(1.38 bar) greater than the
maximum pressure, a Ford
dealer or other tire service
professional should do the
mounting. WARNING:
Always inflate
steel carcass tires with a remote
air fill with the person inflating
standing at a minimum of
12 ft
(3.66 m) away from the wheel
and tire assembly. WARNING:
When inflating
the tire for mounting pressures
up to
20 psi (1.38 bar) greater
than the maximum pressure on
the tire sidewall, the following
precautions must be taken to
protect the person mounting the
tire:
• Make sure that you have the
correct tire and wheel size.
• Lubricate the tire bead and
wheel bead seat area again.

Please note that the TPMS 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 TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS 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. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS 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 TPMS to continue to function
properly.

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.

•
To reduce the chances of interference
from another vehicle, perform the
system reset procedure at least 3 ft
(1 m) 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 can time-out and you have
to repeat the entire procedure on all
four wheels.
• A double horn sounds 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 you successfully
enter the reset mode, the horn sounds
once, the system indicator flashes and
a message shows 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 shows 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 side front tire, Right front -
passenger side front tire, Right rear -
passenger side rear tire, Left rear -
driver 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 tone 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
side rear tire, the system indicator
stops flashing, and a message shows
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.

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 the 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
tire pressure monitoring 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 tire
pressure monitoring system sensor for
damage. Dissimilar Spare Wheel and Tire
