CHANGING THE TIRES
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.
The use of tire sealants is not recommended and may compromise the
integrity of your tires. The use of tire sealants may also affect your tire
pressure monitoring system (if equipped).
Spare tire information
Your vehicle is equipped with a spare tire that may be used as a spare or
a regular tire. The spare is identical to the other tires on your vehicle,
although the wheel may not match.
Roadside Emergencies
236

Make sure that all replacement tires are of the same size, type,
load-carrying capacity and tread design (e.g.,“All Terrain”,
“Touring”, etc.), as originally offered by Ford.
Do not replace your tires with“high performance”tires or larger
size tires.
Failure to follow these precautions may adversely affect the
handling of the vehicle and make it easier for the driver to lose
control and roll over.
Tires that are larger or smaller than your vehicle’s original tires may also
affect the accuracy of your speedometer.
Tire pressure monitoring system (TPMS) (if equipped)
The tire pressure monitoring system provides the driver with a warning
message indicating when tire pressure is severely low or high. This
system is a supplement to normal tire maintenance including regular
manual inspections. The device will inform the operator of severe low or
high inflation pressures, but may not illuminate for less severe
discrepancies in inflation pressure.
The system uses radio-frequency pressure sensors to monitor the tire
pressure on all tires including the spare. The sensors transmit the tire
pressure readings to the receiver module located in the vehicle. The
receiver module then transmits the status to the message center. For
more tire warning information, refer to theMessage Centerin the
Driver controlschapter.
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
checking tire pressure. The tire pressure should be checked
periodically (at least monthly) using a tire gauge, seeChecking the
tire pressurein this chapter. Failure to properly maintain your tire
pressure could increase the risk of tire failure and the potential for
personal injury.
Maintenance and Specifications
298

Changing tires with TPMS
It is recommended that you always
have your tires serviced by a dealer
or qualified technician.Each tire is
equipped with a tire pressure
sensor mounted on the wheel
inside the tire behind 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 toChecking the tire pressurein this chapter.
SNOW TIRES AND CHAINS
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, you may need to use snow
tires and chains.
Follow these guidelines when using snow tires and chains:
•Use only cable type chains or chains offered by Ford as an accessory
or equivalent. Other conventional link type chains may contact and
cause damage to the vehicle’s wheel house and/or body.
•Do not install chains on the front wheels. Chains on the front wheels
may interfere with suspension components.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
•If possible, avoid fully loading your vehicle.
•Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
•The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
Maintenance and Specifications
299

•Mobile communications systems may harm the operation of your
vehicle, particularly if they are not properly designed for automotive
use or are not properly installed. When operated, such systems may
cause the engine to stumble or stall or cause the transmission to be
damaged or operate improperly. In addition, such systems may be
damaged or their performance may be affected by operating your
vehicle. (Citizens band [CB] transceivers, garage door openers and
other transmitters with outputs of five watts or less will not ordinarily
affect your vehicle’s operation.)
•Ford cannot assume responsibility for any adverse effects or damage
that may result from the use of such equipment.
•Do not install equipment which modifies the vehicles suspension or
steering. Such modifications can cause adverse effects to the
AdvanceTrac system.
•Do not install a loudspeaker in the area of the front floor console or
under the front driver or passenger seats. The speaker vibrations can
adversely effect the AdvanceTrac sensors.
