250 SAFETY
NOTE:
Whenever an audible alert is requested by the
BSM system, the radio is also muted.
When the system is in RCP, the system shall
respond with both visual and audible alerts
when a detected object is present. Whenever
an audible alert is requested, the radio is also
muted. Turn/hazard signal status is ignored;
the RCP state always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off, there will
be no visual or audible alerts from either the
BSM or RCP systems.
NOTE:
The BSM system will store the current operating
mode when the vehicle is shut off. Each time
the vehicle is started, the previously stored
mode will be recalled and used.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION
The FCW with Mitigation system provides the
driver with audible warnings, visual warnings
(within the instrument cluster display), and may
apply a limited braking to warn the driver when
it detects a potential frontal collision. The
warnings and limited braking 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 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 warn-
ings 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 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.
If a Forward Collision Warning with Mitigation
event begins at a speed below 39 mph (62 km/
h), the system may provide maximum 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
Ú page 395.
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.
