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 may damage your tires. The use of tire
sealants may also damage your tire pressure monitoring system
(if equipped).
Your vehicle may be equipped with a conventional spare tire that is
different in one or more of the following: type, brand, size, speed rating
and tread design. If this is the case, this dissimilar spare tire is still rated
for your vehicle loads (GAWR and GVWR). Your vehicle is equipped with
a spare wheel that does not match the road wheels and is not equipped
with a Tire Pressure Monitor System (TPMS) sensor.
Spare tire information
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 tire serviced by a
dealer or qualified technician in order to prevent damage to the TPMS
sensor. Replace the spare tire with a road tire as soon as possible.
Location of the spare tire and tools
The spare tire and tools for your vehicle are stowed in the following
locations:
Item Location
Spare tire Under the vehicle, just forward of
the rear bumper
Jack tools and jacking instructions Under the access panel located in
the floor compartment behind the
rear seat
Removing the jack and tools
1. Open the liftgate, then locate the access panel on the floor behind the
3rd row seat. Unlatch and remove the panel.
2. Remove the jack and tools assembly tray from the compartment by
turning the wing-nut counterclockwise to relieve tension against the jack
assembly tray.

Note:This vehicle is equipped with a Tire Pressure Monitoring System
(TPMS) which 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 14 to 28 kPa (2 to 4 psi)
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 20.7 kPa (3 psi) for a drop of 16.6°C (30°F) in
ambient temperature. This lower pressure value may be detected by the
TPMS as being significantly lower than the cold placard pressure, 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, see
Checking the tire 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 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.
