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 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 26 mph (42 km/
h), the system may provide the maximum brak-
ing possible 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 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 acti-
vation and functionality.
• It is unsafe to test the FCW system. To
prevent such misuse of the system, after four
Active Braking events within a key cycle, the
Active Braking portion of FCW will be deacti-
vated until the next key 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 un-
necessary warnings to the surroundings.
WARNING!
Forward Collision Warning (FCW) is not in-
tended 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.
Turning FCW On Or Off
NOTE:
The default status of FCW is "on", this allows the
system to warn you of a possible collision with
the vehicle in front of you.
The forward collision button is located on the
switch panel below the Uconnect display.
