Cross traffic alert (CTA) system operation
The CTA system warns the driver of approaching vehicles when R
(Reverse) is selected and the vehicle is backing out of a front-in parking
spot. It sounds a series of tones and flashes the BLIS
indicator found on
the exterior mirror on the side of the approaching vehicle. Additionally,
the message center will display either, VEHICLE COMING FROM RIGHT
or VEHICLE COMING FROM LEFT to warn the driver from which
direction vehicles are approaching.
The system is not designed to prevent contact with other vehicles or
objects. The system is designed to provide a warning to assist the driver
in detecting vehicles in the blind zones. The system will not detect
infrastructure, pedestrians, or bicyclists.
WARNING:To help avoid personal injury, NEVER use the CTA
system as a replacement for using the side and rear view mirrors
and looking over your shoulder before backing out of a parking space.
CTA is not a replacement for careful driving and only an assist.
The CTA system detects vehicles approaching up to 45 feet (14 meters)
away (approximately the width of five parking spaces). Coverage
decreases when vehicles and objects in close proximity block the CTA
sensors (refer to figure for approximate zone coverage areas[sensor
obstructed for vehicle on left]). Backing slowly from the parking spot
in these situations helps to increase the sensor coverage and
effectiveness.

CTA coverage also decreases when parking at shallow angles (refer to
figure for approximate zone coverage areas[sensor obstructed for
vehicle on left]).
CTA detection limitations:Due to the nature of radar technology,
there may be certain instances where vehicles entering and exiting the
blind spot zones may not be detected. Below is a list of circumstances
that may cause non-detection:
•Debris build up on the rear quarter panel fascias
•The rear quarter panel radar beams are obstructed or partially
obstructed by an adjacently parked vehicle or object.
•Approaching vehicles passing at speeds greater than 15 mph
(24 km/h)
•Severe weather conditions
•Driving in reverse faster than 3 mph (5 km/h)
•Backing out of an angled parking spot
CTA False Alerts
Due to the nature of radar technology, there may be certain instances
when the BLIS
will alert with no object present when backing up. This
is known as a false alert. Some level of false alerts are normal.
Circumstances that may cause a false alert when backing up are backing
out of a garage, backing in to a parking space, and objects very close to
the sensor. False alerts are temporary and self correct.

CTA and Reverse Sensing System (RSS) interaction
CTA works along with the Reverse Sensing System (RSS) (if equipped).
Become familiar with the warning tones of both systems.
BLIS
and/or CTA on/off and disable operation
The BLIS
and/or the CTA can be turned off via the message center. If
either the BLIS
and/or the CTA is turned off, the systems will
automatically turn back on at the next ignition key cycle. When either
the BLIS
and/or the CTA is turned off, the message center displays
BLIND SPOT SYS OFF and/or CTA SYSTEM OFF. When the BLIS

and/or the CTA system is off, the driver will not receive alerts. Refer to
Message centerin theInstrument Clusterchapter.
Note:If the system cannot be turned off, refer toMyKey™in theLocks
and Securitychapter for more information.
The BLIS
and/or the CTA can be disabled permanently even after an
ignition key cycle. This must be done by your authorized dealer.Note:
Once either of the systems are disabled, enabling must also be performed
at the dealership. When disabled, the message center will display BLIND
SPOT DISABLED and/or CTA DISABLED.
BLIS
and/or CTA fault operation
If the BLIS
and/or CTA senses a fault on either the left or right sensor,
the BLIS
alert indicator will go on and remain on and the message
center will display BLIND SPOT SYSTEM FAULT or CROSS TRAFFIC
SYSTEM FAULT. For faults that may cause the associated left or right
alert indicator not to illuminate, only the message center faults will
occur.
Blocked sensor
An extreme build-up of materials on
the quarter panel fascias such as
mud or snow can cause degraded
performance of the BLIS
. Also,
heavy rain can cause the same
effect. The BLIS
can detect this
degraded performance and issue a
blocked warning to the driver via
the message center. If a condition is determined by the system, the
message center displays BLIND SPOT NOT AVAILABLE or CROSS
TRAFFIC NOT AVAILABLE warning and the appropriate left and/or right
exterior mirror alert indicator will illuminate. The message center
warning may be cleared by the driver but the exterior mirror alert
indicator will remain illuminated.

Trailer tow false alerts
When towing a trailer, the sensors may detect the trailer thus causing a
false alert. It may be desirable to turn the BLIS
off if the false alerts
become annoying.
Day and night brightness
The BLIS
and/or CTA alert will automatically dim when the headlamp
switch is in PARK, ON, or AUTO ON and night time darkness has been
detected by the sun sensor.
ALL WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with a full-time All Wheel Drive (AWD)
system. The AWD system is an active system, meaning it not only
responds to wheel slip between the front and rear axles but also has the
ability to anticipate wheel slip and transfer torque to the rear wheels
before slip occurs. The AWD system is active all the time and requires no
input from the operator.
All components of the AWD system are sealed for life and require no
maintenance.
Note:When an AWD system fault is present, the warningCHECK AWD
will display in the message center. The AWD system is not functioning
correctly and defaulted to front wheel drive. When this warning is
displayed, have your vehicle serviced at an authorized dealer
If your vehicle is equipped with AWD, a spare tire of a different size
other than the tire provided should never be used. If the spare tire is
installed, the AWD system may disable automatically and enter front
wheel drive only mode to protect driveline components. This condition
may be indicated by anAWD OFFmessage in the message center (see
Message centersection in theInstrument Clusterchapter for more
information). If there is anAWD OFFmessage in the message center
from using the spare tire, this indicator should turn off after reinstalling
the repaired or replaced normal road tire and driving a short distance. It
is recommended to reinstall the repaired or replaced road tire as soon as
possible. Major dissimilar tire sizes between the front and rear axles
could cause the AWD system to stop functioning and default to front
wheel drive or damage the AWD system.
Note:TheAWD OFFmessage may also be displayed in the message
center if the AWD system has overheated and defaulted to front wheel
drive. This condition may occur if the vehicle was operated in extreme
conditions with excessive wheel slip, such as deep sand. To resume
normal AWD function as soon as possible, stop the vehicle in a safe

CHANGING THE TIRES
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.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare tire is in use. To restore the full functionality
of the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat serviced by an authorized dealer in order to prevent damage
to the TPMS sensors, refer toTire pressure monitoring system
(TPMS)in theTires, Wheels and Loadingchapter. 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 TPMS sensor for
damage.
WARNING:The use of tire sealants may damage your Tire
Pressure Monitoring System and should only be used if it is
supplied with your vehicle as part of the original temporary mobility
kit.
WARNING:Refer toTire pressure monitoring system (TPMS)
in theTires, Wheels and Loadingchapter for important
information. If the tire pressure monitor sensor becomes damaged, it
will no longer function.
Dissimilar spare tire/wheel 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 tire/wheel, 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 tire/wheel 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.
