Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and a chime will sound when condi-
tions temporarily limit system performance.
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 clus-
ter display will display “ACC/FCW Unavailable Wipe
Front Radar Sensor” and the system will deactivate.
This message can sometimes be displayed while driving
in highly reflective areas (i.e. ice and snow, or tunnels
with reflective tiles). 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, Fixed Speed Cruise Control is still
available.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal
of an obstruction. The sensor is located in the camera
in the center of the windshield, on the forward side of
the rearview mirror.
To keep the ACC system operating properly, it is impor-
tant to note the following maintenance items:
•
Always keep the sensor clean. Carefully clear the
windshield.
•
Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure
and require a sensor realignment.
•
Do not attach or install any accessories near the
sensor, including transparent material or aftermar-
ket grilles. Doing so could cause an ACC system fail-
ure 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 Sen-
sor” message occurs frequently (e.g. more than
once on every trip) without any snow, rain, mud, or
other obstructions, have the radar sensor realigned
at an authorized dealer.
•
Installing a snowplow, front-end protector, an after-
market grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit
ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” warning will display and a chime will sound
when conditions temporarily 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 obstructions,
such as mud, dirt, or ice on windshield, driving directly
into the sun and fog on the inside of glass. In these
cases, the instrument cluster display will show “ACC/
FCW Limited Functionality Clean Front Windshield” and
the system will have degraded performance.
This message can sometimes be displayed while driving in
adverse weather conditions. 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 rearview mirror. They may
require cleaning or removal of an obstruction.
When the condition that created limited functionality is no
longer present, the system will return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean Front Wind-
shield” message occurs frequently (e.g. more than once
on every trip) without any snow, rain, mud, or other
obstructions, have the windshield and forward facing
camera inspected at an authorized dealer.
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster dis-
plays “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 functionality. Although the vehicle is still
drivable under normal conditions, ACC will be temporar-
ily unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem persists,
see an authorized dealer.
Precautions While Driving With ACC
NOTE:
•
Aftermarket add-ons such as snowplows, lift kits,
and brush/grille bars can hinder module perfor-
mance. Ensure the radar/camera has no obstruc-
tions in the field of view.
•
Height modifications can limit module performance
and functionality.
•
Do not put stickers or easy passes over the camera/
radar field of view.
