System Lights and Messages
The Blind Spot Information and Cross
Traffic Alert systems illuminate an amber
alert indicator in the outside mirror on the
side of your vehicle the approaching
vehicle is coming from.
The alert indicator dims when the system
detects nighttime darkness.
Cross Traffic Alert sounds also sounds an
audible alarm and a message appears in
the information display indicating a vehicle
is coming from the right or left. Cross
Traffic Alert works with the reverse sensing
system which sounds its own audible
alarm. See Rear Parking Aid (page 182).
System Sensor Blockage
WARNING
Never use the Blind Spot
Information System as a
replacement for using the interior
and exterior mirrors or looking over your
shoulder before changing lanes. The Blind
Spot Information System is not a
replacement for careful driving. Note:
It is possible to get a blockage
warning with no blockage present; this is
rare and known as a false blockage warning.
A false blocked condition either
self-corrects or clears after a key cycle. The system uses radar sensors which are
located behind the bumper fascia on each
side of your vehicle. Do not allow these
areas to become obstructed by mud, snow
or bumper stickers, as this can cause
degraded system performance.
If the system detects a degraded
performance condition, a blocked sensor
warning or low visibility warning will appear
in the information display and the alert
indicator illuminates in the appropriate
mirror(s). The information display warning
can be cleared but the alert indicator
remains illuminated.

When the blockage is removed, the system
can be reset in two ways: 1) when at least
two objects are detected while driving, or
2) turn the ignition key from on to off, then
back on. If the blockage is still present after
the key cycle, the system senses again that
it is blocked after driving in traffic.Reasons for messages being displayed
Clean the fascia area in front of the radaror remove the obstruction.
The radar surface is dirty or obstructed
Drive normally in traffic for a few minutesto allow the radar to detect passing
vehicles so it can clear the blocked state.
The radar surface is not dirty or obstructed
No action required. The system automatic-ally resets to an unblocked state once the rainfall/snowfall rate decreases or stops. Do not use the Blind Spot InformationSystem or Cross Traffic Alert in these conditions.
Heavy rainfall/snowfall interferes with the
radar signals
System Limitations
The Blind Spot Information and Cross
Traffic Alert systems do have their
limitations; situations such as severe
weather conditions or debris build-up on
the sensor area may limit vehicle detection.
The following are other situations that may
limit the Blind Spot Information System:
• Certain maneuvering of vehicles
entering and exiting the blind zone.
• Vehicles passing through the blind zone
at very fast rates.
• When several vehicles forming a
convoy pass through the blind zone.
The following are other situations that may
limit the Cross Traffic Alert:
• Adjacently parked vehicles or objects
obstructing the sensors.
• Approaching vehicles passing at
speeds greater than 15 mph (24 km/h).
• Driving in reverse faster than
3 mph
(5 km/h).
• Backing out of an angled parking spot. False Alerts
Note:
If you connected a trailer to your
vehicle, the Blind Spot Information System
may detect the trailer causing a false alert.
To avoid false alerts you may want to turn
the system off manually.
There may be certain instances when
either the Blind Spot Information or Cross
Traffic Alert systems illuminate the alert
indicator with no vehicle in the coverage
zone; this is known as a false alert. Some
amount of false alerts are normal; they are
temporary and self-correct.
System Errors
If the system senses a problem with the
left or right sensor, the telltale will
illuminate and a message will appear in
the information display. See Information
Messages
(page 102).

CHANGING THE ENGINE AIR
FILTER
WARNING
To reduce the risk of vehicle damage
and personal burn injuries, do not
start your engine with the air cleaner
removed and do not remove it while the
engine is running. Note:
Failure to use the correct air filter
element may result in severe engine
damage. Resulting component damage
may not be covered by the vehicle Warranty.
When changing the air filter element, use
only the air filter element listed. See
Motorcraft Parts (page 304).
Change the air filter element at the correct
interval. See
Scheduled Maintenance
(page 443). 1. Locate the mass air flow sensor
electrical connector on the air outlet
tube. Disconnect the mass air flow
sensor electrical connector. 2. Reposition the locking clip on the
connector (connector shown from
below for clarity), squeeze the
connector and pull it off of the air
outlet tube. 3.
Clean the area from around the air tube
to the air cover connection to prevent
debris from entering the system. Next,
loosen the bolt on the air tube clamp
so the clamp is no longer snug to the
air tube. It is not necessary to
completely remove the clamp.
4. Pull the air tube off from the air cleaner
housing.

WARNINGS
To reduce the risk of serious
injury, when mounting
replacement tires and wheels, you
should not exceed the maximum
pressure indicated on the sidewall
of the tire to set the beads without
additional precautions listed
below. If the beads do not seat at
the maximum pressure indicated,
re-lubricate and try again. 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 ft
(3.66 m)
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. WARNINGS
Always inflate steel carcass
tires with a remote air fill with
the person inflating standing at a
minimum of
12 ft (3.66 m) away
from the wheel and tire assembly. Important: Remember to replace
the wheel valve stems when the
road tires are replaced on your
vehicle.
The two front tires or two rear tires
should generally be replaced as a
pair.
The tire pressure sensors mounted
in the wheels 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, the
system is malfunctioning. Your
replacement tire might be
incompatible with your tire
pressure monitoring system, or
some component of the system
may be damaged.

Tire Rotation
WARNING
If the tire label shows
different tire pressures for the
front and rear tires and the vehicle
has a tire pressure monitoring
system, then you need to update
the settings for the system
sensors. Always perform the
system reset procedure after tire
rotation. If you do not reset the
system, it may not provide a low
tire pressure warning when
necessary. Note:
If your tires show uneven
wear ask an authorized dealer to
check for and correct any wheel
misalignment, tire imbalance or
mechanical problem involved
before tire rotation.
Note: Your vehicle may be
equipped with a dissimilar spare
wheel and tire assembly. 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. If you have a dissimilar
spare wheel and tire assembly it is
intended for temporary use only
and should not be used in a tire
rotation.
Note: After having your tires
rotated, inflation pressure must be
checked and adjusted to the
vehicle requirements. Rotating your tires at the
recommended interval (as
indicated in the Scheduled
Maintenance chapter) will help
your tires wear more evenly,
providing better tire performance
and longer tire life.
Rear-wheel drive vehicles and
four-wheel drive vehicles (front
tires at left of diagram)
Sometimes irregular tire wear can
be corrected by rotating the tires.

This device complies with part 15 of the
FCC Rules and with Licence exempt RSS
Standards of Industry Canada. Operation
is subject to the following two conditions:
•
This device may not cause harmful
interference.
• This device must accept any
interference received, including
interference that may cause undesired
operation.
Changing Tires With a Tire
Pressure Monitoring System 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:
