2016 FORD FLEX sensor

In this first example, the left sensor is only
partially obstructed; zone coverage to the
right is nearly maximized.

Zone coverage also decreases when
parking at shallow angles. Here, the left
sensor is mostly obstructed; zone coverage
on that side is severely limited.
System Lights, Messages and
Audible Alerts
The Cross Traffic Alert illuminates an
amber alert indicator in the outside mirror
on the side of your vehicle the approaching
vehicle is coming from. Cross Traffic Alert
also sounds an audible alert and a
message appears in the information
display indicating a vehicle is coming from
the right or left. Cross Traffic Alert works
with the reverse sensing system that
sounds its own series of tones. See Rear
Parking Aid (page 177). The system uses radar sensors that are
located behind the bumper fascia on each
side of your vehicle. Do not allow mud,
snow or bumper stickers to obstruct these
areas, this can cause degraded system
performance. See Blind Spot
Information System (page 192). If the
Blind Spot Information System is blocked,
Cross Traffic Alert is also blocked. A
corresponding message appears in the
information display as soon as you shift
the transmission into reverse (R).
System Limitations
Cross Traffic Alert has its limitations;
situations such as severe weather
conditions or debris build-up on the sensor
area may limit vehicle detection.
196
Flex (), enUSA, First Printing Driving AidsE142442 E205199

The following are other situations that may
limit the Cross Traffic Alert performance:
•
Stationary or slow moving vehicles.
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lame.
• Severe weather conditions.
• Debris build-up near or around the
sensor(s).
• Small distance to the vehicle ahead.
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.
False Alerts
Note: When towing a trailer, the sensors
may detect the trailer thus causing a false
alert. It may be desirable to turn the Blind
Spot Information System off if the false
alerts become annoying.
There may be certain instances when there
is a false alert by the Cross Traffic Alert
system that illuminates the alert indicator
with no vehicle in the coverage zone. Some
amount of false alerts are normal; they are
temporary and self-correct.
System Errors
If Cross Traffic Alert senses a problem with
the left or right sensor a message will
appear in the information display. See
Information Messages (page 105). Switching the System Off and On
You can temporarily switch Cross Traffic
Alert off in the information display. See
General Information
(page 97). When
you switch Cross Traffic Alert off, you will
not receive alerts and the information
display will display a system off message.
Note: The Cross Traffic Alert switches on
whenever the ignition is switched on and
ready to provide appropriate alerts when
the transmission is in reverse (R). Cross
Traffic Alert will not remember the last
selected on or off setting.
You can also have Cross Traffic Alert
switched off permanently at an authorized
dealer. Once switched off permanently,
the system can only be switched back on
at an authorized dealer.
STEERING
Electric Power Steering WARNINGS
The electric power steering system
has diagnostic checks that
continuously monitor the system. If
a fault is detected, a message displays in
the information display. Stop your vehicle
as soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked by an authorized dealer. If the system detects an error, you
may not feel a difference in the
steering, however a serious condition
may exist. Obtain immediate service from
an authorized dealer, failure to do so may
result in loss of steering control. 197

If it is, a red warning light illuminates and
an audible warning chime sounds.
The brake support system assists the driver
in reducing the collision speed by charging
the brakes. If the risk of collision further
increases after the warning light
illuminates, the brake support prepares
the brake system for rapid braking. This
may be apparent to the driver. The system
does not automatically activate the brakes
but, if the brake pedal is pressed, full force
braking is applied even if the brake pedal
is lightly pressed.
Using the Collision Warning System
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. The warning system sensitivity can be
adjusted to one of three possible settings
by using the information display control.
See General Information (page 97).
Note: If collision warnings are perceived as
being too frequent or disturbing then the
warning sensitivity can be reduced, though
the manufacturer recommends using the
highest sensitivity setting where possible.
Setting lower sensitivity would lead to fewer
and later system warnings. See
General
Information (page 97).
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.

Action
Cause
Clean the grille surface in front of the radaror remove the object causing the obstruc- tion
The surface of the radar in the grille is dirty
or obstructed in some way
Wait a short time. It may take several
minutes for the radar to detect that it is no longer obstructed
The surface of the radar in the grille is clean
but the message remains in the display
The collision warning system is temporarily
disabled. Collision warning should automat-ically reactivate a short time after the weather conditions improve
Heavy rain, spray, snow, or fog is interfering
with the radar signals
The collision warning system is temporarily
disabled. Collision warning should automat-ically 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 signals
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).
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.
