The warning system sensitivity can be
adjusted to one of three possible
settings by using the information
display control. See General
Information (page 101).
Note:If the system cannot be turned
off in a vehicle equipped with MyKey®,
Note: If collision warnings are
perceived as being too frequent or
disturbing then the warning sensitivity
can be reduced, though the
manufacturer recommends using the
highest sensitivity setting where
possible. Setting lower sensitivity
would lead to fewer and later system
warnings. See General Information
(page 101). Blocked Sensors
E145632
If a message regarding a blocked
sensor appears in the information
display, the radar signals from the
sensor have been obstructed. The
sensors are located behind a fascia
cover near the driver side of the lower
grille. When the sensors are
obstructed, a vehicle ahead cannot
be detected and the collision warning
system does not function. The
following table lists possible causes
and actions for this message being
displayed.

Wait a short time. It may take several
minutes for the radar to detect that it is no longer obstructed
The surface of the radar in the grille is
clean but the message remains in the display
The collision warning system is
temporarily disabled. Collision warning should automatically reactivate a
short time after the weather conditions improve
Heavy rain, spray, snow, or fog is inter-
fering with the radar signals
The collision warning system is
temporarily disabled. Collision warning should automatically reactivate a
short time after the weather conditions improve
Swirling water, or snow or ice on the
surface of the road may interfere with the radar signals
System Limitations
WARNING
The collision warning system’s
brake support can only help
reduce the speed at which a collision
occurs if the driver applies the
vehicle’s brakes. The brake pedal
must be pressed just like any typical
braking situation.
Due to the nature of radar technology,
there may be certain instances where
vehicles do not provide a collision
warning. These include: • Stationary vehicles or vehicles
moving below 6 mph (10 km/h).
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lane.
• Severe weather conditions (see blocked sensor section).
• Debris build-up on the grille near the headlamps (see blocked
sensor section).
• Small distance to vehicle ahead.
• Steering wheel and pedal movements are large (very active
driving style).

If the fluid level is below the MIN range
of the dipstick, add fluid to reach the
hash mark level.
Note:
If the fluid level is below the MIN
level, do not drive the vehicle. An
underfill condition may cause shift or
engagement concerns or possible
damage.
Correct fluid level
E158843
The transmission fluid should be
checked at normal operating
temperature 180°F-200°F
(82°C-93°C) on a level surface. The
normal operating temperature can be
reached after approximately 20 miles
(30 kilometers) of driving.
The transmission fluid level should be
targeted within the cross-hatch area
if at normal operating temperature
180°F-200°F (82°C-93°C).

Maintenance

High fluid level
E158844
If the fluid level is above the MAX
range of the dipstick, remove fluid to
reach the hashmark level.
Note:Fluid level above the MAX level
may cause shift or engagement
concerns or possible damage. High
fluid levels can be caused by an
overheating condition. If your vehicle
has been operated for an extended
period at high speeds, in city traffic
during hot weather or pulling a trailer,
the vehicle should be turned off until
normal operating temperatures are
reached. Depending on vehicle use,
cooling times could take up to 30
minutes or longer.

Maintenance

• Only use the sealing compoundbefore the use by date. The use by
date is on the lower right hand
corner of the label located on the
sealant canister (bottle). Check
the use by date regularly and
replace the canister after four
years.
• Do not store the kit unsecured inside the passenger compartment
of the vehicle as it may cause injury
during a sudden stop or crash.
Always store the kit in its original
location.
• After sealant use, the tire pressure monitoring system sensor and
valve stem on the wheel must be
replaced by an authorized Ford
dealer.
• When inflating a tire or other objects, use the black air hose only.
Do not use the transparent hose
which is designed for sealant
application only.
• Operating the kit could cause an electrical disturbance in radio, CD,
and DVD player operation.
What to do when a Tire Is
Punctured
A tire puncture within the tire's tread
area can be repaired in two stages
with the kit. • In the first stage, the tire will be
reinflated with a sealing
compound and air. After the tire
has been reinflated, you will need
to drive the vehicle a short
distance (about 4 miles [6
kilometers]) to distribute the
sealant in the tire.
• In the second stage, you will need to check the tire pressure and
adjust, if necessary, to the vehicle's
tire inflation pressure.
First Stage: Reinflating the Tire
with Sealing Compound and Air
WARNINGS
Do not stand directly over the kit
while inflating the tire. If you
notice any unusual bulges or
deformations in the tire's sidewall
during inflation, stop and call roadside
assistance.
If the tire doesn't inflate to the
recommended tire pressure
within 15 minutes, stop and call
roadside assistance.
Preparation: Park the vehicle in a safe,
level and secure area, away from
moving traffic. Turn the hazard lights
on. Apply the parking brake and turn
the engine off. Inspect the flat tire for
visible damage.
Sealant compound contains latex. To
avoid any allergic reactions, use the
non-latex gloves located in the
accessory box on the underside of the
kit housing.

Wheels and Tires

What to do after the Tire has
been Sealed
After using the kit to seal your tire, you
will need to replace the sealant
canister and clear tube (hose).
Sealing compound and spare parts
can be obtained and replaced at an
authorized Ford Motor Company
dealership or tire dealer. Empty
sealant bottles may be disposed of at
home; however, liquid residue from
the sealing compound should be
disposed by your local Ford Motor
Company dealership or tire dealer, or
in accordance with local waste
disposal regulations.
Note:After the sealing compound has
been used, the maximum vehicle speed
is 50 mph (80 km/h) and the
maximum driving distance is 120 miles
(200 kilometers). The sealed tire
should be inspected immediately.
Note: After sealant use, the tire
pressure monitoring system sensor and
valve stem on the wheel must be
replaced by an authorized Ford dealer.
You can check the tire pressure any
time within the 120 miles (200
kilometers) by performing the
procedure from Second stage:
Checking tire pressure listed
previously. Removal of the sealant canister
from the kit

Changing Tires With a Tire
Pressure Monitoring System
E142549
Note:Each road tire is equipped with
a tire pressure sensor located inside the
wheel and tire assembly cavity. The
pressure sensor is attached to the valve
stem. The pressure sensor is covered
by the tire and is not visible unless the
tire is removed. Take care when
changing the tire to avoid damaging
the sensor
You should always have your tires
serviced by an authorized dealer.
Check the tire pressure periodically
(at least monthly) using an accurate
tire gauge. See Inflating Your Tires in
this chapter.
Understanding Your Tire
Pressure Monitoring System
The tire pressure monitoring system
measures pressure in your four road
tires and sends the tire pressure
readings to your vehicle. The low tire
pressure warning light will turn on if
the tire pressure is significantly low. Once the light is illuminated, your tires
are under-inflated and need to be
inflated to the manufacturer’s
recommended tire pressure. Even if
the light turns on and a short time
later turns off, your tire pressure still
needs to be checked.
When Your Temporary Spare Tire
is Installed
When one of your road tires needs to
be replaced with the temporary spare,
the system will continue to identify an
issue to remind you that the damaged
road wheel and tire assembly needs
to be repaired and put back on your
vehicle.
To restore the full function of the tire
pressure monitoring system, have the
damaged road wheel and tire
assembly repaired and remounted on
your vehicle.
When You Believe Your System is
Not Operating Properly
The main function of the tire pressure
monitoring system is to warn you
when your tires need air. It can also
warn you in the event the system is no
longer capable of functioning as
intended. See the following chart for
information concerning your tire
pressure monitoring system:
305
Wheels and Tires

WARNINGS
When inflating the tire for
mounting pressures up to 20 psi
(1.38 bar) greater than the
maximum pressure on the tire
sidewall, the following
precautions must be taken to
protect the person mounting the
tire:
1. Make sure that you have the
correct tire and wheel size.
2. Lubricate the tire bead and
wheel bead seat area again.
3. Stand at a minimum of 12 feet
(3.66 meters) away from the
wheel and tire assembly.
4. Use both eye and ear
protection.
For a mounting pressure more
than 20 psi (1.38 bar) greater than
the maximum pressure, a Ford
dealer or other tire service
professional should do the
mounting.
Always inflate steel carcass tires
with a remote air fill with the
person inflating standing at a
minimum of 12 feet (3.66 meters)
away from the wheel and tire
assemblyImportant: Remember to replace
the wheel valve stems when the
road tires are replaced on your
vehicle
It is recommended that the two
front tires or two rear tires
generally be replaced as a pair.
The tire pressure sensors mounted
in the wheels (originally installed
on your vehicle) are not designed
to be used in aftermarket wheels.
The use of wheels or tires not
recommended by Ford Motor
Company may affect the
operation of your tire pressure
monitoring system.
If the tire pressure monitoring
system indicator is flashing, your
system is malfunctioning. Your
replacement tire might be
incompatible with your tire
pressure monitoring system, or
some component of the system
may be damaged.
Safety Practices
WARNINGS
If your vehicle is stuck in
snow, mud or sand, do not
rapidly spin the tires; spinning the
tires can tear the tire and cause
an explosion. A tire can explode in
as little as three to five seconds.
Do not spin the wheels at
over 35 mph (56 km/h). The
tires may fail and injure a
passenger or bystander.

USING SNOW CHAINS
WARNINGS
If you choose to install snow tires
on your vehicle, they must be the
same size, construction, and load
range as the original tires listed on the
tire placard, and they must be
installed on all four wheels. Mixing
tires of different size or construction
on your vehicle can adversely affect
your vehicle's handling and braking,
and may lead to loss of vehicle
control.
Do not use snow chains or cables
on this vehicle as they may cause
damage to your vehicle which may
lead to loss of vehicle control.
Snow chains have not been approved
for use on your vehicle.
The original equipment tires on your
vehicle may have an all-weather tread
design to provide traction, handling,
and braking performance in
year-round driving. You may install
snow tires for improved traction when
driving in areas with sustained periods
of snow or icy driving conditions.
CHANGING A ROAD WHEEL
WARNINGS
The use of tire sealants may
damage your tire pressure
monitoring system and should not be
used. However, if you must use a
sealant, the tire pressure monitoring
system sensor and valve stem on the
wheel must be replaced by an
authorized dealer.
If the tire pressure monitor
sensor becomes damaged, it will
no longer function. See Tire Pressure
Monitoring System (page 303).
Note: The tire pressure monitoring
system indicator light will illuminate
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 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.
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 303).
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.
