Jeep Grand Cherokee 2013 Operating Information Manual page 137

Changing the FCW status to "Off" prevents the
system from warning you of a possible collision
with the vehicle in front of you.
Example Only
NOTE:
In the "Off" setting FCW OFF will be dis-
played in the EVIC.
FCW Off Example
NOTE:
• The system will retain the last setting
selected by the driver after ignition shut
down.
• FCW will not react to irrelevant objects
such as overhead objects, ground reflec-
tions, objects not in the path of the car,
stationary objects that are far away, on-
coming traffic, or leading vehicles with
the same or higher rate of speed.
• FCW will be disabled like ACC below with
the unavailable screens.
FCW Unavailable Warning
If the system turns off, and the EVIC displays
"ACC/FCW Unavailable, Vehicle System Error",
there may be a temporary malfunction that
limits FCW functionality. Although the vehicle is
still drivable under normal conditions, FCW will
be temporarily unavailable. If this occurs, try
activating FCW again later, following a key
cycle. If the problem persists, see your autho-
rized dealer.
Service FCW Warning
If the system turns off, and the EVIC displays
"ACC/FCW Unavailable Service Radar Sen-
sor", it indicates there is an internal system fault.
Although the vehicle is still drivable under nor-
mal conditions, have the system checked by an
authorized dealer.
