The installation of replacement tires with steel cord body plies in the tire
sidewall may cause malfunction of the Tire Pressure Monitoring System
(TPMS), and is not recommended (cord material information is molded
on the tire sidewall). Additionally, if your vehicle was originally equipped
with run-flat tires, replacing them with tires that are not identical to
those originally fitted may cause malfunction of the TPMS, and is not
recommended. Run-flat tires should not be used to replace regular tires.
Always check your TPMS indicator immediately after replacing one or
more tires on your vehicle. If the TPMS indicator is on, your TPMS is
malfunctioning. Your replacement tire might be incompatible with your
TPMS system, or some component of the TPMS system may be damaged.
Important:Ford recommends you replace your tires every 6 years
regardless of the condition of the tire tread wear. As tires age, the
rubber weakens, potentially increasing the risk of a tire failure during
use, causing loss of vehicle control and personal injury.
Important:Remember to replace the spare tire when you replace the
road tires on your vehicle. Even if it has never been used, the spare tire
should be replaced because tires degrade over time.
Important:Remember to replace the wheel air valves when the road
tires are replaced on your vehicle.
CHANGING THE TIRES
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
Note:If your vehicle is equipped with the tire pressure monitoring
system (TPMS), the system indicator light will illuminate when the spare
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.
If your vehicle is equipped with TPMS, have a flat serviced by a dealer or
a qualified technician in order to prevent damage to the TPMS sensor,
refer toChanging tires with TPMSin theTires, Wheels and Loading
chapter. Replace the spare tire with a road tire as soon as possible.

TIRE PRESSURE MONITORING SYSTEM (TPMS)(IF EQUIPPED)
When the Tire Pressure Monitoring
System warning light is lit, one or
more of your tires is significantly
under-inflated. You should stop and
check your tires as soon as possible,
and inflate them to the proper pressure as indicated on the vehicle’s tire
information placard (label). Driving on a significantly under-inflated tire
causes the tire to overheat and can eventually lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability. Even if your vehicle is
equipped with a Tire Pressure Monitoring System, it is still important
that you manually check the inflation pressure of your tires regularly.
Each tire, including the spare, should be checked monthly when cold and
set to the recommended inflation pressure which can be found on either
the Safety Compliance Certification Label which is located on the B-Pillar
or the edge of the driver’s door.
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, see
Inspecting and inflating 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.
Changing tires with TPMS
It is recommended that you always
have your tires serviced by a dealer
or qualified technician.Each road
tire is equipped with a tire
pressure sensor mounted on the
wheel inside the tire connected
to the valve stem. The tire
pressure sensor must be
unbolted from the wheel prior to
tire removal. The sensor can be
removed by loosening the nut at the valve stem. Failure to
remove the sensor may damage it.The rubber grommet (washer)
between the wheel and the tire pressure sensor needs to be replaced
whenever the sensor is removed to minimize air leaks.

The tire pressure should be checked periodically (at least monthly) using
an accurate tire gauge, refer toInspecting and inflating your tiresin
this chapter.
Understanding your Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System measures pressure in your four
road tires and sends the tire pressure readings to your vehicle every
minute while you are driving and once an hour when your vehicle is
parked. The Low Tire Warning Lamp will turn ON if the tire pressure is
25% below the pressure listed on the Safety Compliance Certification
Label (approximately 6 to 9 psi below the manufacturer’s recommend
tire pressure). If the tire pressure increases 2 psi above the “Light ON”
threshold, then the TPMS light will turn OFF. 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.
In short, once the light has turned ON, at least one tire may be under
inflated.
When your temporary spare tire is installed
When one of your road tires needs to be replaced with the temporary
spare, the TPMS system will continue to identify an issue to remind you
that the damaged road wheel/tire needs to be repaired and put back on
your vehicle. During this time, the low tire warning light can periodically
return or stay on, depending on the state of the damaged road
wheel/tire. This will include the message center messages (if equipped).
To restore the full functionality of the Tire Pressure Monitoring System,
have the damaged road wheel/tire repaired and remounted on your
vehicle. For additional information, refer toChanging tires with TPMS
in this section.

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. Here are the details:
•The tire pressure monitor sensors mounted in your wheels updates
your vehicle with tire pressure information only once every minute,
therefore it may take up to a minute for the light to turn off after you
have filled your tires to the recommended tire pressure.
•If your vehicle has been parked for over 15 minutes, the sensors go
into a low power mode to conserve battery life and therefore only
transmit about once an hour. If you inflate your tires under these
conditions, the light could take up to an hour to turn off after you
have filled your tires to the recommended tire pressure.
For these reasons, the low tire warning light is NOT a substitute for
using an accurate tire gauge when checking and filling your tires. The
best way to turn off the low tire warning light is to fill your tires to the
recommended tire pressure and drive your vehicle — the tire pressure
sensors in your wheels will update your vehicle with the updated tire
pressure when your vehicle reaches a speed of 20 mph (32 km/h) for at
least a minute.
How temperature affects your tire pressure
The Tire Pressure Monitoring System (TPMS) monitors tire pressure in
each pneumatic tire. The pressure in each tire is dependent upon several
factors, one of them being the contained air temperature (temperature of
the air inside the tire). As the contained air temperature increases, the
tire pressure also increases. 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. This increase in tire pressure
is due to an increase in the contained air temperature. Contained air
temperature is dependent upon several factors such as rate of tire
rotation, tire deflection, amount of braking, etc. In similar manner, the
tire pressure will decrease if the contained air temperature decreases.
For example, if the vehicle is stationary over night with the outside
temperature significantly lower than the daytime temperature, the tire
pressure may decrease approximately 3 psi (20.7 kPa) for a drop of 30°
F (16.6° C) in ambient temperature. This lower pressure value may be
detected by the TPMS as being significantly lower than the cold pressure
indicated on your vehicles Safety Compliance Certification Label, and
activate the TPMS warning for low tire pressure. If the low warning light
is on, visually check each tire to verify that no tire is flat. If one or more

Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles arenot
designed for cornering at speeds as high as passenger cars any more
than low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
•If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
AWD Systems (if equipped)
AWD uses all four wheels to power
the vehicle. This increases traction,
enabling you to drive over terrain
and road conditions that a
conventional two-wheel drive vehicle
cannot.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
If you must reduce the tire pressure for whatever reason in sand, make
sure you re-inflate the tires as soon as possible.
Note:If your vehicle is equipped with the Tire Pressure Monitoring
System (TPMS), the system indicator light may illuminate depending on
how much air is released from your tires and/or how long you drive the
vehicle under these conditions.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
