2012 FORD TAURUS sensor

•Pedestrians or objects in the roadway.
•Oncoming vehicles in the same lane.
•Severe weather conditions (see also blocked sensor section).
•Debris build-up on the grille near the headlamps (see block sensor
section).
•Small distance to vehicle ahead.
•Steering wheel and pedal movements are large (very active driving
style).
•High interior temperatures, which may deactivate the illumination or
the warning lamps until the interior temperature reduces (audible
warning will alert the driver).
In addition, sun load and sunglasses may reduce the visibility of the
warning lamps. Therefore, it is recommended to keep the audible
warning on.
If the front end of the vehicle is hit or damaged, the radar sensing zone
may be altered causing missed or false collision warnings. Check with
your authorized dealer to have your collision warning radar checked for
proper coverage and operation.
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.
Blocked sensor
If a message regarding a blocked
sensor is displayed, the radar signals
from the sensor, located behind a
fascia cover near the driver side of
the lower grille, have been
obstructed. When the radar signals
are obstructed, a vehicle ahead
cannot be detected and the collision
warning system will not function.
The following table lists possible
causes and actions for this message being displayed.

The BLISwill trigger the alert for vehicles that enter your blind zone
from the rear or merge into the blind zone from the side. Vehicles that
you pass, or a vehicle that enters the blind zone from the front, will
trigger the alert only after the vehicle is present in the blind zone for
three seconds.Note:For vehicles that pass through the blind zone
quickly, typically less than two seconds, the BLISwill not illuminate the
alert.
The BLISconsists of two radar
sensors each located rearward of
the rear wheels hidden behind the
bumper fascia. Do not place any
type of bumper sticker in this area.
Note:The BLIStypically will not
detect parked vehicles, humans,
animals, or infrastructure (fences,
guard rails, trees, etc.). The BLIS
does not function when the transmission is in R (Reverse) or P (Park).
The BLISdoes not provide any additional warning when your turn
signal is activated.
BLISdetection 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
•Certain maneuvering of vehicles entering and exiting the blind zone
•Vehicles passing through the blind zone at very fast rates
•Severe weather conditions
•When several vehicles forming a convoy pass through the blind zone.
BLISFalse Alerts
Due to the nature of radar technology, there may be certain instances
when the BLISwill alert with no object present in the blind zone. This
is known as a false alert. Some level of false alerts are normal.
Circumstances that may cause a false alert are; guardrails, freeway
concrete walls, cyclone fencing, sharp turns around a pole or building, or
coming to a stop with a vehicle directly behind but very close. False
alerts are temporary and self correct.

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. 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 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 into 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.
BLISand/or CTA on/off and disable operation
The BLISand/or the CTA can be turned off via the message center. If
either the BLISand/or the CTA is turned off, the systems will
automatically turn back on at the next ignition key cycle. When either
the BLISand/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 toMyKeyin theLocks
and Securitychapter for more information.
The BLISand/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.
BLISand/or CTA fault operation
If the BLISand/or 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 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 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.

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 the blockage is removed, the system will require some driving time
and detection of at least two vehicle objects prior to resetting or the
driver can cycle the ignition key. 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 radar is dirty
or obstructed in some wayClean the fascia area in front of the
radar, either side, or remove
obstruction.
The surface of the 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 reset
to an unblocked state once the
rainfall/snowfall rate decreases or
stops. Do not use BLISand/or 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.
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 BLISoff if the false alerts
become annoying.

Day and night brightness
The BLISand/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 (seeMessage 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
location and allow it to idle. TheAWD OFFmessage will turn off when
the system cools and normal AWD function returns.
Note:Your AWD vehicle is not intended for off-road use. The AWD
feature gives your vehicle some limited off-road capabilities in which
