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 BLISindicator 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 to 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 to
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 BLISwill 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-CTA on/off and disable operation
The BLISand/or the CTA can be turned off via the message center.
Turning the BLISoff does not turn off the CTA and vice-versa. If either
the BLISor CTA is turned off, the systems will automatically turn back
on at the next ignition key cycle. When either the BLISor CTA is
turned off, the message center displays BLIND SPOT SYS OFF and/or
CTA SYSTEM OFF. When the BLISor CTA system is off, the driver will
not receive alerts. Refer toMessage centerin theInstrument Cluster
chapter.
The BLIS-CTA can be disabled permanently even after an ignition key
cycle. This must be done by your dealership service technician.
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-CTA fault operation
If the BLIS-CTA senses a fault on either the left or right sensor, the
BLISalert 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 left and/or right quarter panel
fascias such as mud or snow can
cause degraded performance of the
BLIS. Also, heavy rain can cause
the same effect. The BLIScan
detect this degraded performance
and issue a blocked warning to the
driver via the message center. If 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.

WARNING:Just prior to the system recognizing a blocked
condition and alerting the driver, the number of missed objects
will increase. To help avoid injuries, NEVER use the BLISas a
replacement for using the side and rear view mirrors and looking over
your shoulder before changing lanes. BLISis not a replacement for
careful driving and only an assist.
Once blockage is removed, the system will require some driving time and
detection of at least two vehicle object prior to realizing it is unblocked,
or the driver can cycle the ignition key. If blocked and the ignition key is
cycled, the system resets to unblocked. If however blockage is still
present after the key cycle, the system will sense again that it is blocked
after driving in traffic.
The following table lists possible causes and actions for this message
being displayed:
The surface of the left or right radar
is dirty or obstructed in some wayClean the fascia area in front of the
radar, either left or right side, or
remove obstruction.
The surface of the left or right radar
is not dirty or obstructedDrive normally in traffic for a few
minutes to allow the radar to detect
that it is no longer blocked.Note:
the vehicle must be in D (Drive) and
a few vehicles must pass so that the
BLIScan clear a blocked state.
Heavy rainfall or heavy snowfall is
interfering with the radar signalsNo action required by the driver.
The system will automatically go
unblocked once the rainfall/snowfall
rate decreases or stops. Do not use
BLIS-CTA in heavy rainfall or heavy
snowfall.
Due to the nature of radar technology, it is possible to get a blockage
warning and not be blocked. This is rare and known as a false blockage
warning. A false blocked condition will either self clear or clear after a
key cycle.
Day and night brightness
The BLIS-CTA alert will automatically dim when the headlamp switch is
in the parking, on, or autolamp position and night time darkness has
been detected by the sun sensor.

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 (TPMS) and should not be used.
However, if you must use a sealant, the TPMS sensor and valve stem
on the wheel must be replaced by an authorized Ford dealer.
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.
A dissimilar spare tire/wheel is defined as a spare tire and/or wheel 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
2.Full-size dissimilar spare with label on wheel:This spare tire has
a label on the wheel that states: “THIS TIRE AND WHEEL FOR
TEMPORARY USE ONLY”
When driving with one of the dissimilar spare tires listed above,do not:
•Exceed 50 mph (80 km/h)
•Load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
•Tow a trailer
•Use snow chains on the end of the vehicle with the dissimilar spare
tire
•Use more than one dissimilar spare tire at a time
