FORD 2013 Flex v.3 - Manual (Page 248)

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 and chime can be turned on and off separately; the
warning system sensitivity can be adjusted to one of three possible
settings by using the information display control. Refer to the
Information Displays chapter.
Note: If the system cannot be turned off in a vehicle equipped with
MyKey®, refer to the MyKey® chapter.
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. Refer to the Information Displays chapter for instructions on
reducing the sensitivity.
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 way Clean 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 display Wait a short time. It may take
several minutes for the radar to
detect that it is no longer
obstructed
