WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
The tire pressure monitoring
system measures the vehicle's
tire pressures. A warning lamp
illuminates if one or more tires are
significantly underinflated or if there is a
system malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW WARNING: If the tire pressure
monitor sensor becomes damaged it
may not function. 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! WARNING:
To determine the
required pressure(s) for your vehicle, see
the Safety Compliance Certification
Label (on the door hinge pillar,
door-latch post or the door edge that
meets the door-latch post, next to the
driver seat) or the Tire Label on the
B-Pillar or the edge of the driver door. Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure
recommended by the vehicle manufacturer
on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on
the vehicle placard or tire inflation pressure
label, you should determine the proper tire
inflation pressure for those tires).
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. 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.
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.

CHANGING A FLAT TIRE
WARNING: If the tire pressure
monitor sensor becomes damaged it
may not function.
Note: The use of tire sealant may damage
your tire pressure monitoring system and
should only be used in roadside
emergencies.
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 this 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 to prevent damage to the system
sensors.
See Tire Pressure Monitoring
System Precautions (page 449). Replace
the spare tire with a road tire as soon as
possible. During repairing or replacing the
flat tire, have the authorized dealer inspect
the system sensor for damage.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death. If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires
and wheels that were originally provided
by Ford. If the dissimilar spare tire or wheel
is damaged, it should be replaced rather
than repaired.
A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and
wheels.
Full-size dissimilar spare
When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
•
Exceed
70 mph (113 km/h).
• Use more than one dissimilar spare
wheel and tire assembly at a time.
• Use snow chains on the end of the
vehicle with the dissimilar spare wheel
and tire assembly.
When driving with the full-size dissimilar
spare wheel and tire assembly, 4WD
functionality may be limited. You may
experience the following:
• Additional noise from the transfer case
or other drive components.
• Difficulty shifting out of a mechanically
locked 4WD mode.
When driving with the full-size dissimilar
spare wheel and tire assembly, it is
recommended that you do not:
• Exceed
50 mph (80 km/h) in 4WD.
• Engage 4WD unless the vehicle is
stationary.
• Use 4WD on dry pavement.

The usage of a full-size dissimilar spare
wheel and tire assembly 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.
• Four-wheel drive capability. When driving with the full-size dissimilar
spare wheel and tire assembly 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 full-size
dissimilar spare wheel and tire assembly
and seek service as soon as possible.

2. Slide the wheel partially under the
vehicle and install the retainer through
the wheel center. If equipped, you may
have to remove the wheel center cap
prior to pushing the retainer through
the center of the wheel. To remove the
center cap, press it off with the lug
wrench tip from the inner side of the
wheel. Pull on the cable to align the
components at the end of the cable.
3. Reinsert the lug wrench extension(s) through the rear bumper and guide
tube and turn the lug wrench clockwise
until the tire is raised to its stowed
position underneath the vehicle. The
wrench will become harder to turn and
the spare tire winch will ratchet or slip
when the tire is raised to maximum
tightness. You will hear a clicking sound
from the winch indicating that the tire
is properly stowed, tighten until a
minimum of three clicks are heard.
Check that the tire lies flat against the
frame and is secure.
4. Carefully place all tools back in the tool
kit bag.
5. Reinstall the tool kit bag and tighten the wing nut.
6. Properly reinstall the jack into the bracket and tighten the wing nut. WHEEL NUTS WARNING: When you install a
wheel, always remove any corrosion, dirt
or foreign materials present on the
mounting surfaces of the wheel or the
surface of the wheel hub, brake drum or
brake disc that contacts the wheel. Make
sure to secure any fasteners that attach
the rotor to the hub so they do not
interfere with the mounting surfaces of
the wheel. Installing wheels without
correct metal-to-metal contact at the
wheel mounting surfaces can cause the
wheel nuts to loosen and the wheel to
come off while your vehicle is in motion,
resulting in loss of vehicle control,
personal injury or death. lb.ft (Nm)

again at 500 mi (800 km) of new vehicle
operation and after any wheel disturbance,
such as tire rotation, changing a flat tire,
or wheel removal.
It is important to follow the proper wheel
mounting and lug nut torque procedures.
