warnings, then the system will provide a limited
level of active braking to help slow the vehicle and
mitigate the potential forward collision. If the driver
reacts to the warnings by braking and the system
determines that the driver intends to avoid the
collision by braking but has not applied sufficient
brake force, the system will compensate and
provide additional brake force as required.
If a Forward Collision Warning with Mitigation event
begins at a speed below 39 mph (62 km/h), the
system may provide maximum 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

3 mph (5 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 deacti-
vated 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 unnec-
essary warnings to the surroundings. If the
vehicle enters 4WD Low, the FCW system will be
automatically deactivated.
page 372.
Ú 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
page 193.
Ú
NOTE:
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
an audible/visual warning when the latter is at a
farther distance than the "Medium" setting. This
provides the most reaction time to avoid a
possible collision.
