NOTE:
• If the "ACC / FCW Unavailable Wipe Front
Radar Sensor" message occurs frequently
(e.g. more than once on every trip) without
any snow, rain, mud, or other obstruction,
have the radar sensor realigned at your au-
thorized 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 highly reflective areas
(i.e. tunnels with reflective tiles, or ice and
snow). 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.

Removing ACC Sensor For Off-Roading
NOTE:
When off-roading, it may be advisable to
remove the ACC sensor. The sensor is lo-
cated behind the front lower grille in the
center of the vehicle. After removing the
lower fascia, you may remove the lower
sensor and bracket assembly.
To remove the sensor follow these instructions:
1. Unplug the connector by depressing the two
tabs on the connector and pulling it out. Do not
pull by the wiring or use any tools to remove the
connector.
2. Remove the wiring christmas tree attach-
ment from the back of the bracket.
3. Remove the two M6 fasteners that connect
the bracket to the bumper.
NOTE:
Do not change the adjustment fasteners or
pull the sensor off of the bracket. Doing so
may misalign the sensor.
