To restore the full functionality of the Tire Pressure Monitoring System,
have the damaged road wheel/tire repaired and remounted on your
vehicle. For additional information, refer toChanging tires with TPMS
in this section.
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. Please refer to the following
chart for information concerning your Tire Pressure Monitoring System:

When inflating your tires
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 (TPMS) monitors tire pressure in
each pneumatic tire. While driving in a normal manner, a typical
passenger tire inflation pressure may increase approximately 2 to 4 psi
(14 to 28 kPa) from a cold start situation. If the vehicle is stationary
over night with the outside temperature significantly lower than the
daytime temperature, the tire pressure may decrease approximately 3 psi
(21 kPa) for a drop of 30°F (17°C) in ambient temperature. This lower
pressure value may be detected by the TPMS as being significantly lower
than the recommended inflation pressure and activate the TPMS warning
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 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.

SNOW TIRES AND CABLES
WARNING:Snow tires must be the same size, load index, speed
rating as those originally provided by Ford. Use of any tire or
wheel not recommended by Ford can affect the safety and
performance of your vehicle, which could result in an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
Additionally, the use of non-recommended tires and wheels could
cause steering, suspension, axle or transfer case/power transfer unit
failure.
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 cables. If you need to use cables, it is recommended that steel
wheels (of the same size and specifications) be used, as cables may chip
aluminum wheels.
Follow these guidelines when using snow tires and traction devices:
•SAE class “S” cables or chains should ONLY be used on the front axle
for either P235/70R16 or P225/65R17 tires.
•Install cables securely, verifying that the cables do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the cables rub or bang against the
vehicle, stop and retighten them. If this does not work, remove the
cables to prevent vehicle damage.
•Avoid overloading your vehicle.
•Remove the cables when they are no longer needed.
•Do not use cables on dry roads.
•Do not exceed 30 mph (48 km/h) with tire cables on your vehicle.
Consult your authorized dealer for information on other Ford Motor
Company approved methods of traction control.

The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned on) until the
parking brake is released.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
WARNING:Always set the parking brake fully and make sure
that the gearshift is securely latched in P (Park).
The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.

The AdvanceTrac
with RSC
system provides the following stability
enhancement features for certain driving situations:
•Traction Control (TCS), which functions to help avoid drive-wheel
spin and loss of traction
•Electronic Stability Control (ESC), which functions to help avoid skids
or lateral slides
•Roll Stability Control™ (RSC
), which functions to help avoid a
vehicle roll-over
The AdvanceTrac
with RSC
system automatically enables each time
the engine is started. All features of the AdvanceTrac
with RSC
system
(TCS, ESC, and RSC
) are active and monitor the vehicle from start-up.
However, the system will only intervene if the driving situation requires
it.
The AdvanceTrac
with RSC

system includes an AdvanceTrac

with RSC
“Off” button on the
instrument panel below the climate
control, and a “sliding car” icon
in the instrument cluster. The
“sliding car” icon
in the instrument cluster will illuminate temporarily
during start-up as part of a normal system self-check, or during driving if
a driving situation causes the AdvanceTrac
with RSC
system to
operate. If the “sliding car” icon
illuminates steadily, verify that the
AdvanceTrac
with RSC
system is not manually disabled by pressing
the AdvanceTrac
with RSC
“Off” button located on the instrument
panel. If the “sliding car” icon
remains steadily illuminated, have the
system serviced by an authorized dealer immediately.
Note:If the system cannot be turned off, refer toMyKey™in theLocks
and Securitychapter for more information.
When AdvanceTrac
with RSC
performs a normal system self-check,
some drivers may notice a slight movement of the brake, and/or a
rumble, grunting, or grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTrac
with RSC
you may
experience the following:
•A slight deceleration of the vehicle
•The “sliding car”
indicator light will flash.
•A vibration in the pedal when your foot is on the brake pedal

AUTOMATIC TRANSMISSION OPERATION
Automatic transmission adaptive learning
Your transmission is equipped with an adaptive learning strategy found in
the vehicle computer. This feature is designed to increase durability and
provide consistent shift feel over the life of the vehicle. A new vehicle or
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation. Additionally, whenever the battery is
disconnected or a new battery installed, the strategy must be relearned.
Understanding the gearshift positions of the 6–speed automatic
transmission
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.
P (Park)
This position locks the transmission
and prevents the front wheels from
turning.
To put your vehicle in gear:
1. Press the brake pedal.
2. Move the gearshift lever into the
desired gear.
To put your vehicle in P (Park):
1. Come to a complete stop.
2. Move the gearshift lever and
securely latch it in P (Park).

Note:If the system cannot be turned off, refer toMyKey™in theLocks
and Securitychapter for more information.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
REARVIEW CAMERA SYSTEM (IF EQUIPPED)
The rearview camera system located
on the liftgate provides a video
image, which appears in the
rearview mirror or on the navigation
screen (if equipped), of the area
behind the vehicle. It adds
assistance to the driver while
reversing or reverse parking the
vehicle.
To use the camera, place the transmission in R (Reverse); an image will
display on the left portion of the rearview mirror or on the navigation
screen (if equipped). The area displayed on the screen may vary
according to the vehicle orientation and/or road condition.
•(1) Rear bumper
•(2) Red zone
•(3) Yellow zone
•(4) Green zone
•(5) Centerline of vehicle
Always use caution while backing.
Objects in the red zone are closest
to your vehicle and objects in the
green zone are further away. Objects
are getting closer to your vehicle as they move from the green zone to
the yellow or red zones.
Use the side mirrors and rearview mirror to get better coverage on both
sides and rear of the vehicle.

Troubleshooting
Why isn’t APA searching for a parking space?
•You may have deactivated the AdvanceTrac
system.
•One of the doors (except the driver’s door) may not be securely
closed.
Why doesn’t APA offer a particular parking space?
•Something may be contacting the front bumper or side sensors. Clear
any material stuck to the sensors.
•There may not be enough room to maneuver the vehicle into the
space. Remember, there needs to be enough space on the opposite
side of the vehicle to allow the front of the vehicle to swing out as you
back into the space.
•The vehicle is not driven close enough to the parking space, less than
60 inches [1.5 m] from neighboring parked vehicles.
•The vehicle is driven too close to the side objects (e.g. less than
16 inches [41 cm] from neighboring parked vehicles).
•You may be driving in R (Reverse). APA can only look for a parking
space while moving forward.
Why doesn’t APA position the vehicle where I want in the space?
•The driver allows the vehicle to roll in the opposite direction of the
transmission (such as rolling forward when R (Reverse) gear is
selected.
•You may be driving in R (Reverse). APA can only look for a parking
space while moving forward.
•There may be an irregular curb along the parking space. APA might
not be able to align the vehicle to curbs that are damaged, very
shallow or covered with material such as debris, leaves, snow, or tarps.
•The vehicles or objects bordering the space may not be positioned
appropriately.
•The vehicle was steered more that usual while driving by the space.
APA performs best when you drive the same distance from the
parking space the entire length of the space.
•The tires may not be installed and maintained correctly. For example,
one or more tires may not be inflated correctly, may not be of the
same size, or may not be authorized for use on this vehicle.
•The vehicle had a repair or alteration that is not authorized by the
manufacturer.
