If a Forward Collision Warning with Mitigation
event begins at a speed below 26 mph
(42 km/h), the system may provide the
maximum or partial braking to mitigate the
potential forward collision. If the Forward
Collision Warning with Mitigation event stops
the vehicle completely, the system will hold the
vehicle at a standstill for two seconds and then
release the brakes.
FCW Message
When the system determines a collision with
the vehicle in front of you is no longer probable,
the warning message will be deactivated.
NOTE:
The minimum speed for FCW activation is

1 mph (2 km/h).
The FCW alerts may be triggered on objects

other than vehicles, such as guard rails or
sign posts based on the course prediction.
This is expected and is a part of normal FCW
activation and functionality.
It is unsafe to test the FCW system. To

prevent such misuse of the system, after four
Active Braking events within an ignition cycle,
the Active Braking portion of FCW will be
deactivated until the next ignition cycle.
The FCW system is intended for on-road use

only. If the vehicle is taken off-road, the FCW
system should be deactivated to prevent
unnecessary warnings to the surroundings. If
the vehicle enters 4L Range or ESC "Full Off"
Mode is active, the FCW system will be auto-
matically deactivated.
WARNING!
Forward Collision Warning (FCW) is not
intended to avoid a collision on its own, nor
can FCW detect every type of potential
collision. The driver has the responsibility to
avoid a collision by controlling the vehicle via
braking and steering. Failure to follow this
warning could lead to serious injury or death.
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status
are programmable through the Uconnect
System. Refer to "Uconnect Settings" in
"Multimedia" for further information.
The default sensitivity of FCW is the "Medium"
setting and the system status is "Warning &
Braking". This allows the system to warn the
driver of a possible collision with the vehicle in
front using audible/visual warnings and it
applies autonomous braking.
Changing the FCW status to the "Far" setting
allows the system to warn the driver of a
possible collision with the vehicle in front using
audible/visual warning when the latter is at a
farther distance than "Medium" setting. This
provides the most reaction time to avoid a
possible collision.
Changing the FCW status to the "Near" setting,
allows the system to warn the driver of a
possible collision with the vehicle in front when
the distance between the vehicle in the front is
much closer. This setting provides less reaction
time than the "Far" and "Medium" settings,
which allows for a more dynamic driving
experience.
