activityDisplay 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 instrument cluster display will
display “ACC/FCW Unavailable Wipe Front Radar Sen-
sor” 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.

STARTING AND OPERATING 355

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 important
to note the following maintenance items:
•Always keep the sensor clean. Carefully clear the wind-
shield.
• 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 aftermarket grilles.
Doing so could cause an ACC system failure or malfunc-
tion.
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
obstruction, have the radar sensor realigned at your
authorized dealer.
• Installing a snow plow, front-end protector, an aftermar-
ket 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 Wind-
shield” 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 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.
356 STARTING AND OPERATING

Stationary Objects And Vehicles
ACC does not react to stationary objects and stationary
vehicles. For example, ACC will not react in situations
where the vehicle you are following exits your lane and the
vehicle ahead is stopped in your lane. Always be attentive
and ready to apply the brakes if necessary.

Normal (Fixed Speed) Cruise Control Mode
In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Cruise Control mode is available for cruising
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 accelerator. Speed
Control can only be operated if the vehicle speed is above
20 mph (32 km/h).
Stationary Object And Stationary Vehicle Example
6
STARTING AND OPERATING 361

To change between the different control modes, push the
Adaptive Cruise Control (ACC) on/off button which turns
the ACC on and the Normal (Fixed Speed) Cruise Control
off. Pushing 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. 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 se-
lected.
To Set A Desired Speed
Turn the Normal (Fixed Speed) Cruise Control
on. When the vehicle has reached the desired
speed, push the SET (+) or SET (-) button and
release. Release the accelerator and the vehicle
will operate at the selected speed. Once a speed has been set a message “CRUISE CONTROL SET TO MPH (km/h)”
will appear indicating what speed was set. This light will
turn on when the system is turned on via the on/off
control. It turns green when the cruise control is set.
To Vary The Speed Setting
To Increase Speed
When the Normal (Fixed Speed) Cruise Control is set, you
can increase speed by pushing the SET
(+)button.
