320 SAFETY
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION IF EQUIPPED
FCW with Mitigation provides the driver with
audible warnings, visual warnings (within the
instrument cluster display), and may apply a
haptic warning in the form of a brake jerk, to
warn the driver when it detects a potential
frontal collision. The warnings are intended to
provide the driver with enough time to react,
avoid or mitigate the potential collision.
NOTE:
FCW monitors the information from the forward
looking sensors as well as 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 warn-
ings as well as a possible haptic warning in the
form of a brake jerk.
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 warn-
ings 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. When towing
a trailer, the system will also respond to activate
the trailer brakes (if equipped).
If an FCW with Mitigation event begins at a
speed below 32 mph (52 km/h), the system
may provide the maximum braking 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
Ú page 490.
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.
WARNING!
The Blind Spot Monitoring system is only an
aid to help detect objects in the blind spot
zones. The BSM system is not designed to
detect pedestrians, bicyclists, or animals.
Even if your vehicle is equipped with the BSM
system, always check your vehicle’s mirrors,
glance over your shoulder, and use your turn
signal before changing lanes. Failure to do so
can result in serious injury or death.
