SAFETY 239
This provides the most reaction time to avoid a
possible collision. The “Far” setting may result in a
greater number of FCW possible collision warnings
experienced.

Changing the FCW status to the “Near” setting allows
the system to warn the driver of a possible collision
with the vehicle in front when the distance between the
vehicle in the front is much closer. This setting provides
less reaction time than the “Far” and “Medium”
settings, which allows for a more dynamic driving expe -
rience. The “Near” setting may result in a lesser
number of FCW possible collision warnings experi -
enced.
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.

FCW may not react to irrelevant objects such as over -
head 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 unavailable
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”. This indicates that
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)
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.
