Display Warnings And Maintenance
“Clean Radar Sensor In Front Of Vehicle” Warning
The ACC “Clean Radar Sensor In Front Of Vehicle”
warning will display when conditions 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
EVIC will display “Clean Radar Sensor In Front Of
Vehicle” and the system will deactivate.
The “Clean Radar Sensor In Front Of Vehicle” message
can sometimes be displayed while driving in highly
reflective areas (i.e. tunnels 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.
222 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:If the ACC “Clean Radar Sensor In Front Of
Vehicle” 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 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 is damaged due to a collision, see your
authorized 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 “Clean Radar Sensor In Front Of Vehicle”
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
authorized dealer.
•Installing a snow plow, 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 Unavailable Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable, Vehicle System Error”, there may be a
temporary malfunction that limits ACC functionality.
Although the vehicle is still drivable under normal
conditions, ACC will be temporarily unavailable. If this
occurs, try activating ACC again later, following a key
cycle. If the problem persists, see your authorized dealer.
Service ACC Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable Service Radar Sensor”, it indicates
there is an internal system fault. Although the vehicle is
still drivable under normal conditions, have the system
checked by an authorized dealer.

Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpect-
edly. The driver needs to stay alert and may need to
intervene.
Adding A Trailer Hitch
The weight of a trailer/hitch may affect the performance
of ACC. If there is a noticeable change in performance
following the installation of a trailer/hitch, or if the ACC
performance does not return to normal after removing
the trailer/hitch see your authorized dealer.

Normal (Fixed Speed) Cruise Control Mode
In addition to Adaptive Cruise Control mode, a normal
(fixed speed) Cruise Control mode is available for cruis-
ing at fixed speeds. The normal Cruise Control mode is
designed to maintain a set cruising speed without requir-
ing the driver to operate the accelerator. Cruise Control
can only be operated if the vehicle speed is above 20 mph
(32 km/h).
To change between the different cruise modes, press the
MODE button when the system is in either the OFF,
READY or SET state. Pressing of the MODE button in any
state will result in changing to the new Mode in the OFF
state.WARNING!
In the normal Cruise Control mode, the system will
not react to vehicles ahead. In addition, the proximity
warning does not activate and no alarm will sound
even if you are too close to the vehicle ahead since
neither the presence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected. Be sure to
maintain a safe distance between your vehicle and
the vehicle ahead. Always be aware which mode is
selected.
To Set A Desired Speed
When the vehicle reaches the speed desired, press the
SET-button and release. The EVIC will display the set
speed.
NOTE: You must observe the display when setting or
changing speed, not the speedometer.

Forward Collision Warning — If Equipped
Forward Collision Warning (FCW) warns the driver of a
potential collision with the vehicle in front of you and
prompts the driver to take action in order to avoid the
collision.
FCW monitors the information from the forward looking
sensor as well as the Electronic Brake Controller (EBC),
wheel speed sensors, i.e., to calculate a probable rear-end
collision. When the system determines that a rear-end
collision is probable a warning message (both audible
and visual) will be displayed on the EVIC. When the
system determines a collision with the vehicle in front of
you is no longer probable, the warning message will be
deactivated.When entering or driving in a curve, the FCW alerts may
be triggered on objects other than vehicles such as guard
rails or sign posts based on the course prediction. This is
expected and is a part of normal FCW activation and
functionality.
FCW Message
232 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:
•The minimum speed for FCW activation is 10 mph
(16 km/h).
•When entering or driving in a curve, the FCW alerts
may be triggered on objects other than vehicles such as
guard rails or sign posts based on the course predic-
tion. This is expected and is a part of normal FCW
activation and functionality.
WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect
every type of potential collision. The driver has the
responsibility to avoid a collision by controlling the
vehicle via braking and steering. Failure to follow
this warning could lead to serious injury or death.
Changing FCW Status
The FCW feature can be set to far, set to near or turned off
in the Electronic Vehicle Information Center (EVIC) refer
to “Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further in-
formation. The FCW Status Off, Near or Far will be
displayed in the EVIC.
FCW settings can only be changed when the vehicle is in
PARK.

Changing the FCW status to “Off” prevents the system
from warning you of a possible collision with the vehicle
in front of you.
NOTE:In the “Off” setting FCW OFF will be displayed
in the EVIC. NOTE:
•The system will retain the last setting selected by the
driver after ignition shut down.
