manufacturer’s recommended pressure
as shown on the Tire Label (located on
the edge of driver ’s door or the B-Pillar),
the vehicle must be driven for at least
two minutes over 20 mph (32 km/h)
before the light turns off.

When Inflating Your Tires WARNING:
Do not use the tire
pressure displayed in the information
display as a tire pressure gauge. Failure to
follow this instruction could result in
personal injury or death. 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.
It may take up to two minutes of driving
over 20 mph (32 km/h) for the light to turn
off after you have filled your tires to the
recommended inflation pressure.

How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase about 2
–4 psi (14– 28 kPa)
from a cold start situation. If the vehicle is
stationary overnight with the outside
temperature significantly lower than the
daytime temperature, the tire pressure may
decrease about 3 psi (21 kPa) for a drop of
30°F (17°C) in ambient temperature. This
lower pressure value may be detected by
the tire pressure monitoring system as
being significantly lower than the
recommended inflation pressure and
activate the system warning light for low
tire pressure. If the low tire pressure
warning light is on, visually check each tire
to verify that no tire is flat. If one or more
tires are flat, repair as necessary. Check
the air pressure in the road tires. If any tire
is under-inflated, carefully drive the vehicle
to the nearest location where air can be
added to the tires. Inflate all the tires to
the recommended inflation pressure.
CHANGING A ROAD WHEEL WARNING:
If the tire pressure
monitor sensor becomes damaged it may
not function.
Note: You should only use tire sealants in
roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.
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 the vehicle. If you get a flat tire when driving, do not
heavily apply the brake. 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 in order to prevent damage to the
tire pressure monitoring system sensors.
See
Tire Pressure Monitoring System
(page 333). Replace the spare tire with a
road tire as soon as possible. During
repairing or replacing of the flat tire, have
the authorized dealer inspect the tire
pressure monitoring 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
and can be one of three types:
1. T-type mini-spare:
This spare tire
begins with the letter T for tire size and
may have Temporary Use Only molded in
the sidewall.

GENERAL INFORMATION
WARNING: Driving while distracted
can result in loss of vehicle control, crash
and injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the safe
operation of your vehicle. We recommend
against the use of any hand-held device
while driving and encourage the use of
voice-operated systems when possible.
Make sure you are aware of all applicable
local laws that may affect the use of
electronic devices while driving. Radio Frequencies and Reception
Factors
AM and FM frequencies are established by
the Federal Communications Commission
(FCC) and the Canadian Radio and
Telecommunications Commission (CRTC).
Those frequencies are:
•
AM: 530-1710 kHz
• FM: 87.9-107.9 MHz
Note: Listening to loud audio for long
periods of time could damage your hearing. Radio Reception Factors
The further you travel from an AM or FM station, the
weaker the signal and the weaker the reception.
Distance and strength
Hills, mountains, tall buildings, bridges, tunnels, freeway
overpasses, parking garages, dense tree foliage and
thunderstorms can interfere with the reception.
Terrain
When you pass a ground-based broadcast repeating
tower, a stronger signal may overtake a weaker one and
result in the audio system muting.
Station overload
CD and CD Player Information
Note: CD units play commercially pressed
4.7 in (12 cm) audio compact discs only. Due
to technical incompatibility, certain
recordable and re-recordable compact discs
may not function correctly when used in the
vehicle ’s CD player.
Note: Do not insert CDs with homemade
paper (adhesive) labels into the CD player
as the label may peel and cause the CD to
become jammed. You should use a
permanent felt tip marker rather than
adhesive labels on your homemade CDs.
Ballpoint pens may damage CDs. Ask an
authorized dealer for more information. Note:
Do not use any irregularly shaped
discs or discs with a scratch protection film
attached.
Always handle discs by their edges only.
Clean the disc with an approved CD
cleaner only. Wipe it from the center of
the disc toward the edge. Do not clean in
a circular motion.
Do not expose discs to direct sunlight or
heat sources for extended periods.

broadcasts provide a better sound quality
than analog broadcasts with free,
crystal-clear audio and no static or
distortion. For more information, and a
guide to available stations and
programming, please visit
www.hdradio.com.
When HD Radio is on and you tune to a
station broadcasting HD Radio technology,
you may notice the HD Radio logo on your
screen. When this logo is available, you
may also see Title and Artist fields
on-screen.
The multicast indicator appears in FM
mode (only) if the current station is
broadcasting multiple digital broadcasts.
The highlighted numbers signify available
digital channels where new or different
content is available. HD1 signifies the main
programming status and is available in
analog and digital broadcasts. Other
multicast stations (HD2 through HD7) are
only available digitally.
When HD Radio broadcasts are active, you
can access the following functions:
•
Scan allows you to hear a brief
sampling of all available stations. This
feature still works when HD Radio
reception is on, although it does not
scan for HD2-HD7 channels. You may
see the HD logo appear if the station
has a digital broadcast.
• Memory presets
allow you to save an
active channel as a memory preset.
Touch and hold a memory preset slot
until the sound returns. There is a brief
mute while the radio saves the station.
Sound returns when finished. When
switching to an HD2 or HD3 memory
preset, the sound mutes before the
digital audio plays, because the system
has to reacquire the digital signal.
Note: As with any saved radio station, you
cannot access a station you save if your
vehicle is outside the station ’s reception
area.
HD Radio Reception and Station Troubleshooting Potential Reception Issues
If you are listening to a multicast station and you are on
the fringe of the reception area, the station may mute due
to weak signal strength.
Reception area
If you are listening to HD1, the system switches back to
the analog broadcast until the digital broadcast is available
again. However, if you are listening to any of the possible
HD2-HD7 multicast channels, the station mutes and stays
muted unless it is able to connect to the digital signal
again.
When the system first receives a station (aside from HD2-
HD7 multicast stations), it first plays the station in the
analog version. Once the receiver verifies the station is an
HD Radio station, it shifts to the digital version. Depending
on the station quality, you may hear a slight sound change
when the station changes from analog to digital. Blending
is the shift from analog to digital sound or digital back to
analog sound.

HD Radio technology is the digital
evolution of analog AM/FM radio. Your
system has a special receiver that allows
it to receive digital broadcasts (where
available) in addition to the analog
broadcasts, it already receives. Digital
broadcasts provide a better sound quality
than analog broadcasts with free,
crystal-clear audio and no static or
distortion. For more information, and a

When HD Radio is on and you tune to a
station broadcasting HD Radio technology,
you may notice the following indicators on
your screen: The HD logo is grey when acquiring a digital
station, and then changes to orange when
digital audio is playing. When this logo is
available, you may also see Title and Artist
fields on-screen.
The multicast indicator appears in FM
mode (only) if the current station is
broadcasting multiple digital broadcasts.
The highlighted numbers signify available
digital channels where new or different
content is available. HD1 signifies the main
programming status and is available in
analog and digital broadcasts. Other
multicast stations (HD2 through HD7) are
only available digitally.
