SAFETY 283
When FCW status is set to “Only Warning”,
this 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.
When FCW status is set to “Warning and
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.
The FCW system state is defaulted to “Full
On” from one ignition cycle to the next. If the
system is turned off, it will reset to “Full On”
when the vehicle is restarted.
FCW Braking Status And Sensitivity
The FCW sensitivity and Active Braking status
are programmable through the Uconnect
system Ú page 228.
Far
When the sensitivity of FCW is set to the
“Far” setting and the system status is
“Warning and Braking”, this allows the
system to warn the driver of a possible
more distant collision with the vehicle in
front using audible/visual warnings.
More cautious drivers that do not mind
frequent warnings may prefer this
setting.
Medium
When the sensitivity of FCW is set to the
“Medium” setting and the system status
is “Warning and Braking”, this allows the
system to warn the driver of a possible
collision with the vehicle in front using
audible/visual warnings.
Near
When the sensitivity of FCW is set to the
“Near” setting and the system status is
“Warning and Braking”, this allows the
system to warn the driver of a possible
closer collision with the vehicle in front
using audible/visual warnings.
This setting provides less reaction time
than the “Far” and “Medium” settings,
which allows for a more dynamic driving
experience.
More dynamic or aggressive drivers that
want to avoid frequent warnings may
prefer this setting.
FCW Limited Warning
If the instrument cluster displays “ACC/FCW
Limited Functionality” or “ACC/FCW 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, and the instrument
cluster displays:
ACC/FCW Unavailable Service Required
Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault.
Although the vehicle is still drivable under
normal conditions, have the system checked by
an authorized dealer.
