Dodge Charger SRT 392 2017 Operating Information Manual page 87

This most often occurs at times of poor visibility,
such as in snow or heavy rain. The ACC system
may also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will read
"ACC/FCW Unavailable Wipe Front Radar Sen-
sor" and the system will deactivate.
The "ACC/FCW Unavailable Wipe Front Radar
Sensor" message can sometimes be displayed
while driving in highly reflective areas (i.e. tun-
nels with reflective tiles, or ice and snow). The
ACC system will recover after the vehicle has
left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects
in its path this warning may temporarily occur.
NOTE:
If the "ACC/FCW Unavailable Wipe Front Radar
Sensor" warning is active, Normal (Fixed
Speed) Cruise Control is still available. For
additional information, refer to "Normal (Fixed
Speed) Cruise Control Mode" in this section.
If weather conditions are not a factor, the driver
should examine the sensor. It may require
cleaning or removal of an obstruction. The sen-
sor is located in the center of the vehicle behind
the lower grille.
To keep the ACC System operating properly, it is
important to note the following maintenance
items:
84
• Always keep the sensor clean. Carefully wipe
the sensor lens with a soft cloth. Be cautious
not to damage the sensor lens.
• Do not remove any screws from the sensor.
Doing so could cause an ACC system mal-
function or failure and require a sensor
realignment.
• If the sensor or front end of the vehicle is
damaged due to a collision, see your autho-
rized dealer for service.
• Do not attach or install any accessories near
the sensor, including transparent material or
aftermarket grilles. Doing so could cause an
ACC system failure or malfunction.
When the condition that deactivated the system
is no longer present, the system will return to the
"Adaptive Cruise Control Off" state and will
resume function by simply reactivating it.
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 obstruc-
tions, such as mud, dirt, or ice on windshield,
and fog on the inside of glass. In these cases,
the instrument cluster display will read "ACC/
FCW Limited Functionality Clean Front Wind-
shield" and the system will have degraded per-
formance.
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 function-
ality is no longer present, the system will return
to full functionality.
