SAFETY 231
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 guardrails 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 4WD Low, the FCW
system will be automatically deactivated.
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status are
programmable through the Uconnect system
Ú page 181.
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 colli-
sion with the vehicle in front using audible/visual warn-
ings 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.
The “Far” setting may result in a greater number of
FCW possible collision warnings experienced.
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.
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 rate of speed.
FCW will be disabled like ACC, with the unavailable
screens.
FCW Limited Warning
If the instrument cluster displays “Automatic Emergency
Braking (AEB) Limited Service Required” or “Limited
Functionality Clean Front Windshield” momentarily, there
may be a condition that limits FCW functionality. Although
the vehicle is still drivable under normal conditions, the
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, the instrument cluster displays
“AEB Unavailable Service Required.”
AEB Unavailable Service Required indicates there is an
internal system fault. Although the vehicle is still drivable
under normal conditions, have the system checked by an
authorized dealer.
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.
