Roadside Emergencies

The usage of a dissimilar spare tire/wheel can lead to impairment of the
following:
•Handling, stability and braking performance
•Comfort and noise
•Ground clearance and parking at curbs
•Winter weather driving capability
•Wet weather driving capability
•All-Wheel Driving Capability (if applicable)
•Load Leveling Adjustment (if applicable)
When driving with the dissimilar spare tire/wheel additional caution
should be given to:
•Towing a trailer
•Driving vehicles equipped with a camper body
•Driving vehicles with a load on the cargo rack
Drive cautiously when using a dissimilar spare tire/wheel and seek
service as soon as possible.
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.
Replace the spare tire with a road tire as soon as possible.
If your vehicle is equipped with AWD, a spare tire of a different
size than the road tires should not be used. Such a tire could
make the vehicle difficult to control as well as result in damage to
driveline components.

Never spin the tires in excess of the 35 mph (55 km/h) point
indicated on the speedometer.
Highway hazards
No matter how carefully you drive there’s always the possibility that you
may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
If you feel a sudden vibration or ride disturbance while driving, or you
suspect your tire or vehicle has been damaged, immediately reduce your
speed. Drive with caution until you can safely pull off the road. Stop and
inspect the tires for damage. If a tire is under-inflated or damaged,
deflate it, remove wheel and replace it with your spare tire and wheel. If
you cannot detect a cause, have the vehicle towed to the nearest repair
facility or tire dealer to have the vehicle inspected.
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 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 as specified on the vehicle placard
(label) and in the owner’s manual.
Note: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 tire 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 tires
are flat, repair of fix as necessary. If all tires appear to be inflated,
carefully drive the vehicle to the nearest location where air can be added
to the tires. Turn the ignition to the “off” position. Inflate all the tires to
the recommended cold pressure.
The system uses radio-frequency to monitor the tire pressure on all tires
excluding the spare tire. The sensors transmit the tire pressure readings
to the receiver module located in the vehicle. The receiver module then
electronically transmits the status to the message center. For more tire
warning information, refer to theMessage Centerin theDriver controls
chapter.
This device complies with part 15 of the FCC rules and with RS-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.
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, seeTire
inflation pressurein 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
when any tire is changed to minimize air leaks.
The tire pressure should be checked periodically (at least monthly) using
a tire gauge, refer toTire inflation pressurein this chapter.
USING SNOW TIRES AND TRACTION DEVICES
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all-weather treads to provide traction in
rain and snow. However, in some climates, using snow tires or traction
devices may be necessary. Ford offers tire cables as a Ford approved
accessory and recommends use of these or SAE class “S” tire cables. See
your dealer or qualified service technician for more information on tire
cables for your vehicle.
Follow these guidelines when using snow tires and traction devices:
•Cables or chains should only be used on the rear wheels.
•Install cables or chains securely, verifying that the cables or chains do
not touch any wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the cables or chains rub or bang against
the vehicle, stop and retighten them. If this does not work, remove the
cables or chains to prevent vehicle damage.
•Avoid overloading your vehicle.
•Remove the cables or chains when they are no longer needed.
•Do not use cables or chains on dry roads.
