SAFETY 263
The “Near” setting may result in a lesser
number of FCW possible collision warnings
experienced.
NOTE:

Changing the FCW status to “Only Warning”
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, but maintains the
audible and visual warnings.

Changing the FCW status to “Off” prevents the
system from providing autonomous braking, or
additional brake support if the driver is not
braking adequately in the event of a potential
frontal collision.

The system will retain the last setting selected
by the driver after ignition shut down.

FCW may not react to irrelevant objects such as
overhead objects, ground reflections, objects
not in the path of the vehicle, stationary objects
that are far away, oncoming traffic, or leading
vehicles with the same or higher rate of speed.

FCW will be disabled like ACC, with the unavail -
able screens.
FCW Limited Warning
If the instrument cluster displays “Automatic
Emergency Braking (AEB) Limited Service
Required” or “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, the instrument cluster
displays “AEB Unavailable Service Required.”
AEB Unavailable Service Required indicates there
is an internal system fault. Although the vehicle is
still drivable under normal conditions, have the
system checked by an authorized dealer.
Pedestrian Emergency Braking (PEB) —
If Equipped
PEB is a subsystem of the Forward Collision
Warning (FCW) system which provides the driver
with audible warnings and visual warnings, in the
instrument cluster display. It may apply limited
automatic braking when it detects a potential
frontal collision with a pedestrian/cyclist.
PEB Message
If a PEB event begins at a speed below 39 mph
(62 km/h), the system may provide maximum
braking to mitigate the potential collision with a
pedestrian/cyclist. If the PEB event stops the
vehicle completely, the system will hold the vehicle
at a standstill for two seconds and then release the
brakes. When the system determines a collision
with the pedestrian/cyclist in front of you is no
longer probable, the warning message will be
deactivated.
The minimum speed for PEB activation is 3 mph
(5 km/h).
