2012 FORD EXPLORER warning

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 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.
FOUR WHEEL DRIVE (4WD) SYSTEM (IF EQUIPPED)
WARNING:For important information regarding safe operation
of this type of vehicle, seePreparing to drive your vehiclein
this chapter.
Your vehicle is equipped with an intelligent 4WD system that
continuously monitors vehicle conditions and automatically adjusts the
power distribution between the front and rear wheels. It combines
transparent all-surface operation with highly capable four-wheel drive.
The 4WD system is always active and requires no driver input. It is
capable of handling all road conditions, including street and highway
driving as well as off-road and winter driving. The driver can optimize
the 4WD by moving the TMS switch for the correct terrain. SeeTerrain
managementlater in this chapter.
Driving off-road with truck and utility vehicles
4WD vehicles are specially equipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
How your vehicle differs from other vehicles
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
Maintain steering wheel control at all times, especially in rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside. Do not
grip the spokes.

Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. To maintain
steering and braking control of your vehicle, you must have all four
wheels on the ground and they must be rolling, not sliding or spinning.
Basic operating principles
•Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
•Be extremely careful when driving on pavement made slippery by
loose sand, water, gravel, snow or ice.
If your vehicle goes off the edge of the pavement
WARNING:Vehicles with a higher center of gravity such as
utility and four-wheel drive vehicles handle differently than
vehicles with a lower center of gravity. Utility and four-wheel drive
vehicles are not designed for cornering at speeds as high as passenger
cars any more than low-slung sports cars are designed to perform
satisfactorily under off-road conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these vehicles. Failure to drive
cautiously could result in an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
•If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
•It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
•It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or roll over. Remember, your safety and the
safety of others should be your primary concern.
If your vehicle gets stuck
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.

Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
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:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Emergency maneuvers
WARNING:Vehicles with a higher center of gravity such as
utility and four-wheel drive vehicles handle differently than
vehicles with a lower center of gravity. Utility and four-wheel drive
vehicles are not designed for cornering at speeds as high as passenger
cars any more than low-slung sports cars are designed to perform
satisfactorily under off-road conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these vehicles. Failure to drive
cautiously could result in an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle, i.e.,
turn the steering wheel only as rapidly and as far as required to avoid
the emergency. Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.

Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application
and brake overheating. Do not
descend in neutral; instead,
disengage overdrive or manually
shift to a lower gear. When
descending a steep hill, avoid
sudden hard braking as you could
lose control. When you brake hard,
the front wheels cannot turn and if
they are not turning, you will not be
able to steer. The front wheels have to be turning in order to steer the
vehicle.
Since your vehicle has anti-lock brakes, apply the brakes steadily. Do not
“pump” the brakes.
Driving on snow and ice
WARNING:If you are driving in slippery conditions that require
tire chains or cables, then it is critical that you drive cautiously.
Keep speeds down, allow for longer stopping distances and avoid
aggressive steering to reduce the chances of a loss of vehicle control
which can lead to serious injury or death. If the rear end of the vehicle
slides while cornering, steer in the direction of the slide until you
regain control of the vehicle.
4WD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
Avoid sudden braking as well. Although a 4WD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions.
