sensor FORD FLEX 2015 1.G Owner's Guide

If the system detects a degraded performance condition, a blocked
sensor warning or low visibility warning will appear in the information
display and the alert indicator illuminates in the appropriate mirror(s).
The information display warning can be cleared but the alert indicator
remains illuminated.
When the blockage is removed, the system can be reset in two ways: 1)
when at least two objects are detected while driving, or 2) turn the
ignition key from on to off, then back on. If the blockage is still present
after the key cycle, the system senses again that it is blocked after
driving in traffic.
Reasons for messages being displayed
The radar surface is
dirty or obstructedClean the fascia area in front of the radar or
remove the obstruction.
The radar surface is
not dirty or obstructedDrive normally in traffic for a few minutes to
allow the radar to detect passing vehicles so it
can clear the blocked state.
Heavy rainfall/snowfall
interferes with the
radar signalsNo action required. The system automatically
resets to an unblocked state once the
rainfall/snowfall rate decreases or stops. Do
not use BLIS® and/or CTA in these conditions.
System Limitations
The BLIS® and CTA systems do have their limitations; situations such as
severe weather conditions or debris build-up on the sensor area may
limit vehicle detection.
The following are other situations that may limit the BLIS®:
•Certain maneuvering of vehicles entering and exiting the blind zone.
•Vehicles passing through the blind zone at very fast rates.
•When several vehicles forming a convoy pass through the blind zone.
The following are other situations that may limit the CTA system:
•Adjacently parked vehicles or objects obstructing the sensors.
•Approaching vehicles passing at speeds greater than 15 mph
(24 km/h).
•Driving in reverse faster than 3 mph (5 km/h).
•Backing out of an angled parking spot.

False Alerts
Note:If you connected a trailer to your vehicle the BLIS® system may
detect the trailer causing a false alert. To avoid false alerts you may want
to turn the BLIS off manually.
There may be certain instances when either the BLIS® or CTA systems
illuminate the alert indicator with no vehicle in the coverage zone; this is
known as a false alert. Some amount of false alerts are normal; they are
temporary and self-correct.
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 you switch off the Blind Spot Information System, you will not
receive alerts and the information display will display a system off
message. The yellow alert indicator in the outside mirror will also flash
twice. The system switches back on whenever you switch the ignition on.
You can also have one or both systems switched off permanently at an
authorized dealer. Once switched off, the system can only be switched
back on at an authorized dealer.
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.

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.

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).

High fluid level
If the fluid level is above the MAX
range of the dipstick, remove fluid to
reach the hashmark level.Note:
Fluid level above the MAX level may
cause shift and/or engagement concerns and/or possible damage.
High fluid levels can be caused by an overheating condition. If your
vehicle has been operated for an extended period at high speeds, in city
traffic during hot weather or pulling a trailer, the vehicle should be
turned off until normal operating temperatures are reached. Depending
on vehicle use, cooling times could take up to 30 minutes or longer.
Adjusting Automatic Transmission Fluid Levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and also in theTechnical
specificationssection in this chapter.
Note:Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
If necessary, add fluid in 1/2 pint
(250 ml) increments through the
filler tube until the level is correct.
If an overfill occurs, excess fluid
should be removed by an authorized
dealer.
Note:An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
For vehicles equipped with the EcoBoost engine, reinstall the air filter
assembly.
After the fluid level has been checked and adjusted as necessary, do the
following:
1. Shut the engine off.
2. Loosen the clamp holding the air filter assembly to the rubber hose.
3. Rotate the air filter assembly 90 degrees clockwise without
disconnecting the sensor.
