164 SAFETY
NOTE:
FCW monitors the information from the forward looking
sensors as well as the Electronic Brake Controller (EBC) to
calculate the probability of a forward collision. When the
system determines that a forward collision is probable, the
driver will be provided with audible and visual warnings
and may provide a brake jerk warning. If the driver does
not take action based upon these progressive 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 suffi-
cient brake force, the system will compensate and provide
additional brake force as required.
If an FCW with Mitigation event begins at a speed below
38 mph (62 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 4WD Low, the FCW
system will be automatically deactivated Ú�page 271.
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status are
programmable through the Uconnect system
Ú page 135.
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 warnings when the
latter is at a farther distance than the “Medium” setting.
This provides the most reaction time to avoid a possible
collision.
NOTE:
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
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.
