WARNING!
When the ACC system is resumed, the driver must
ensure that there are no pedestrians, vehicles or
objects in the path of the vehicle. Failure to follow
these warnings can result in a collision and death or
serious personal injury.
Display Warnings And Maintenance
RADAR SENSOR UNAVAILABILITY WARNING
The “ACC Front Radar Sensor Temporarily Blinded”
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 this warning message 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 Front Radar Sensor Temporarily Blinded”
warning is active, Fixed Speed Cruise Control can be
still enabled.
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 center of
the vehicle behind the lower grille.
To keep the ACC system operating properly, it is impor-
tant to note the following maintenance items:
•
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 malfunction or failure
and require a sensor realignment.
•
If the sensor or front end of the vehicle is damaged
due to a collision, see an authorized dealer for
service.
•
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 Front Radar Sensor Temporarily Blinded”
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 operation.
“ACC LIMITED FUNCTIONALITY CAMERA
BLOCKED” WARNING
The “ACC Limited Functionality Camera Blocked”
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,
low sun, heavy rain, or fog. The ACC system may also
become temporarily blinded due to obstructions, 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 Limited Functionality Camera Blocked”
and the system will have degraded performance.
This message can sometimes be displayed while driving
in adverse weather conditions. The ACC 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 tempo-
rarily occur.
If weather conditions are not a factor, the driver should
examine the windshield and clean it if it’s dirty.
When the condition that created limited functionality is
no longer present, the system will return to full
functionality.
NOTE:
If the “ACC Limited Functionality Camera Blocked” mes-
sage occurs frequently (e.g. more than once on every
trip) without any low sun, snow, rain, mud, or other
obstructions, have the windshield and forward facing
camera inspected at an authorized dealer.
SERVICE ACC WARNING
If the system turns off, and the instrument cluster dis-
play reads “ACC Unavailable Service Required” or
“Cruise Unavailable Service Required”, there may be an
internal system fault or a temporary malfunction that
