308 SAFETY
 When FCW status is set to "Only Warning", this
prevents the system from providing limited Active
Braking, or additional brake support if the driver is not
braking adequately in the event of a potential frontal
collision.
 When FCW status is set to "Warning and Braking", this
allows the system to warn the driver of a possible colli-
sion with the vehicle in front using audible/visual warn-
ings and it applies autonomous braking.
 The FCW system state is defaulted to "Full On" from
one ignition cycle to the next. If the system is turned off,
it will reset to "Full On" when the vehicle is restarted.
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status are
programmable through the Uconnect system
page 226.
Ú
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.
By changing the FCW status setting to "Far", the system
provides possible collision warnings on objects farther
away. This results in earlier warnings and provides the
most reaction time to avoid possible collisions.
NOTE:
The "Far" setting may result in a greater number of FCW
possible collision warnings experienced.
By changing the FCW status setting to "Near", the system
provides possible collision warnings on objects closer to
the vehicle. This results in later warnings and provides
less reaction time than the "Far" and "Medium" settings,
which allows for a more dynamic driving experience.
NOTE:
The "Near" setting may result in a lesser number of FCW
possible collision warnings experienced.
NOTE:
 Changing the FCW status to "Only Warning" prevents
the system from providing limited active braking, or
additional brake support if the driver is not braking
adequately in the event of a potential frontal collision,
but maintains the audible and visual warnings.
 Changing the FCW status to "Off" prevents the system
from providing autonomous braking, or additional
brake support if the driver is not braking adequately in
the event of a potential frontal collision.
 The system will retain the last setting selected by the
driver after ignition shut down.
 FCW may not react to irrelevant objects such as over-
head objects, ground reflections, objects not in the
path of the vehicle, stationary objects that are far away,
oncoming traffic, or leading vehicles with the same or
higher rates of speed.
 FCW will be disabled like ACC, with the unavailable
screens.
FCW Limited Warning
If the instrument cluster displays "ACC/FCW Limited
Functionality" or "ACC/FCW Limited Functionality Clean
Front Windshield" momentarily, there may be a condition
that limits FCW functionality. Although the vehicle is still
drivable under normal conditions, Active Braking may not
be fully available. Once the condition that limited the
system performance is no longer present, the system will
return to its full performance state. If the problem persists,
see an authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster
displays:
 ACC/FCW Unavailable Service Required
 Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although
the vehicle is still drivable under normal conditions, have
the system checked by an authorized dealer.
Pedestrian Emergency Braking (PEB) —
If Equipped
PEB is a subsystem of the Forward Collision Warning
(FCW) system which provides the driver with audible
warnings and visual warnings, in the instrument cluster
display. It may apply limited automatic braking when it
detects a potential frontal collision with a pedestrian/
cyclist.
