Precautions While Driving With Acc - Jeep Cherokee 2014 Owner's Manual

NOTE:
• If the "ACC / FCW Unavailable Wipe Front
Radar Sensor" message occurs fre-
quently (e.g. more than once on every
trip) without any snow, rain, mud, or other
obstruction, have the radar sensor re-
aligned at your authorized dealer.
• Installing a snow plow, front-end protec-
tor, an aftermarket grille or modifying the
grille is not recommended. Doing so may
block the sensor and inhibit ACC / FCW
operation.
"Clean Front Windshield" Warning
The "ACC / FCW Limited Functionality Clean
Front Windshield" warning will display and also
a chime will indicate when conditions temporar-
ily limit system performance. This most often
occurs at times of poor visibility, such as in snow
or heavy rain and fog. The ACC system may
also become temporarily blinded due to ob-
structions, such as mud, dirt, or ice on wind-
shield and fog on the inside of glass. In these
cases, the EVIC will display "ACC / FCW Lim-
ited Functionality Clean Front Windshield" and
the system will have degraded performance.

The "ACC / FCW Limited Functionality Clean
Front Windshield" message can sometimes be
displayed while driving in adverse weather con-
ditions. The ACC / FCW system will recover
after the vehicle has left these areas. Under
rare conditions, when the camera is not tracking
any vehicles or objects in its path this warning
may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rear view
mirror. They may require cleaning or removal of
an obstruction.
When the condition that created limited func-
tionality is no longer present, the system will
return to full functionality.
NOTE:
If the "ACC / FCW Limited Functionality
Clean Front Windshield" message occurs
frequently (e.g. more than once on every
trip) without any snow, rain, mud, or other
obstruction, have the windshield and for-
ward facing camera inspected at your autho-
rized dealer.
Service ACC/FCW Warning
If the system turns off, and the EVIC displays
"ACC/FCW Unavailable Service Required"or
"Cruise/FCW Unavailable Service Required",
there may be an internal system fault or a
temporary malfunction that limits ACC function-
ality. Although the vehicle is still drivable under
normal conditions, ACC will be temporarily un-
available. If this occurs, try activating ACC
again later, following a key cycle. If the problem
persists, see your authorized dealer.

brake late or unexpectedly. The driver needs to
stay alert and may need to intervene.
