WARNING!
Leaving the Adaptive Cruise Control (ACC) system on
when not in use is dangerous. You could accidentally
set the system or cause it to go faster than you want.
You could lose control and have a collision. Always
leave the system off when you are not using it.
To Set A Desired ACC Speed
When the vehicle reaches the speed desired, push the
SET+button or the SET -button and release. The EVIC
will display the set speed.
If the system is Set when the vehicle speed is below
20 mph (32 km/h), the Set Speed shall be defaulted to
20 mph (32 km/h). If the system is Set when the vehicle
speed is above 20 mph (32 km/h), the Set Speed shall be
the current speed of the vehicle. NOTE:
ACC cannot be set if there is a stationary vehicle
in front of your vehicle in close proximity.
Remove your foot from the accelerator pedal. If you do
not, the vehicle may continue to accelerate beyond the set
speed. If this occurs:
• The message “DRIVER OVERRIDE” will display in
the EVIC.
• The system will not be controlling the distance be-
tween your vehicle and the vehicle ahead. The vehicle
speed will only be determined by the position of the
accelerator pedal.

The following conditions cancel the system:
• The brake pedal is applied.
• You press the CANCEL switch.

•If your vehicle stays at standstill for longer than two
seconds, then the system will cancel and the brake
force will be ramped-out. The driver will have to apply
the brakes to keep the vehicle at a standstill.

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 also a chime will indicate 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 “ACC/
FCW Unavailable Wipe Front Radar Sensor” 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. 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.
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 sensor is located in the center of the
vehicle behind the lower grille.
212 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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 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 “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 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/FCW operation.

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 (Fixed Speed) Cruise
Control mode is designed to maintain a set cruising
speed without requiring the driver to operate the accel-
erator. Cruise Control can only be operated if the vehicle
speed is above 20 mph (32 km/h). To change between the different cruise control modes,
press the ADAPTIVE CRUISE CONTROL (ACC) ON/
OFF button which turns the ACC and the NORMAL
(Fixed Speed) CONTROL OFF. Pressing of the NORMAL
(Fixed Speed) CRUISE CONTROL ON/OFF button will
result in turning ON (changing to) the Normal (Fixed
Speed) Cruise Control mode.WARNING!
In the Normal (Fixed Speed) Cruise Control mode,
the system will not react to vehicles ahead. Be sure to
maintain a safe distance between your vehicle and
the vehicle ahead. Always be aware which mode is
selected. Failure to follow these warnings can result
in a collision and death or serious personal injury.
