2014 FORD FLEX sensor

System Errors
If either system senses a problem with the left or right sensor, the
BLIS® indicator in the information display will illuminate and remain on.
Also,BLIND SPOT SYSTEM FAULTorCROSS TRAFFIC SYSTEM
FAULTmessage will appear. When problems that may cause the left or
right indicator not to illuminate, only the information display message
faults appear.
Switching the Systems Off and On
One or both systems can be switched off temporarily by using the
information display control; refer to theInformation Displaychapter.
When the BLIS® is switched off, the driver does not receive alerts and
the information display shows BLIND SPOT SYS OFF and/or CTA
SYSTEM OFF. The system switches back on whenever the ignition is
switched on.
One or both systems can also be switched off permanently at your
authorized dealer. Once switched off, switching it back on must also be
done at the dealership.
COLLISION WARNING SYSTEM (IF EQUIPPED)
WARNING:This system is designed to be a supplementary
driving aid. It is not intended to replace the driver’s attention,
and judgment, or the need to apply the brakes. This system does NOT
activate the brakes automatically. Failure to press the brake pedal to
activate the brakes may result in a collision.
WARNING:The collision warning system with brake support
cannot help prevent all collisions. Do not rely on this system to
replace driver judgment and the need to maintain distance and speed.
Note:The system does not detect, warn or respond to potential
collisions with vehicles to the rear or sides of the vehicle.
Note:The collision warning system is active at speeds above
approximately 5 mph (8 km/h).

Blocked Sensors
If a message regarding a blocked
sensor appears in the information
display, the radar signals from the
sensor have been obstructed. The
sensors are located behind a fascia
cover near the driver side of the
lower grille. When the sensors are
obstructed, a vehicle ahead cannot
be detected and the collision warning system does not function. The
following table lists possible causes and actions for this message being
displayed.
Cause Action
The surface of the radar in the
grille is dirty or obstructed in
some wayClean the grille surface in front of
the radar or remove the object
causing the obstruction
The surface of the radar in the
grille is clean but the message
remains in the displayWait a short time. It may take
several minutes for the radar to
detect that it is no longer
obstructed
Heavy rain, spray, snow, or fog is
interfering with the radar signalsThe collision warning system is
temporarily disabled. Collision
warning should automatically
reactivate a short time after the
weather conditions improve.
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signalsThe collision warning system is
temporarily disabled. Collision
warning should automatically
reactivate a short time after the
weather conditions improve.

System Limitations
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.
Due to the nature of radar technology, there may be certain instances
where vehicles do not provide a collision warning. These include:
•Stationary vehicles or vehicles moving below 6 mph (10 km/h).
•Pedestrians or objects in the roadway.
•Oncoming vehicles in the same lane.
•Severe weather conditions (see blocked sensor section).
•Debris build-up on the grille near the headlamps (see blocked 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 still sounds).
Certain conditions may reduce the visibility of the warning lamp;
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. See your
authorized dealer to have your collision warning radar checked for
proper coverage and operation.
STEERING
Electric Power Steering
WARNING:The electric power steering system has diagnostic
checks that continuously monitor the system to ensure proper
operation. When a system error is detected a steering message will
appear in the information display.

7. Without disconnecting the sensor (4), pull the air filter assembly up to
disconnect the air filter assembly from the seated grommets located
underneath the air filter assembly.
8. Rotate the air filter assembly
90 degrees counterclockwise and
reinstall into the rubber hose.
9. Tighten the clamp (1).
10. The transmission fluid level indicator can now be accessed.
Low fluid level
If the fluid level is below the MIN
range of the dipstick, add fluid to
reach the hash mark level.Note:If
the fluid level is below the MIN level,
do not drive the vehicle. An underfill condition may cause shift and/or
engagement concerns and/or possible damage.
Correct fluid level
The transmission fluid should be checked at normal operating
temperature 180°F-200°F (82°C-93°C) on a level surface. The normal
operating temperature can be reached after approximately 20 miles
(30 km) of driving.
The transmission fluid level should be
targeted within the cross-hatch area
if at normal operating temperature
180°F-200°F (82°C-93°C).
