DISPLAY WARNINGS AND
M
AINTENANCE
“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
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.
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.

STARTING AND OPERATING171
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.
To keep the ACC System operating properly, it is
important 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 autho -
rized 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 an autho -
rized dealer.
Installing a snow plow, front-end protector,
an aftermarket 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 Windshield” 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 and fog on the inside of glass. In
these cases, the instrument cluster display will
display “ACC/FCW Limited Functionality Clean
Front Windshield” and the system will have
degraded performance.
The “ACC/FCW Limited Functionality Clean
Front Windshield” 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 rear view
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.

172STARTING AND OPERATING
NOTE:
If the “ACC/FCW Limited Functionality Clean
Front Windshield” message occurs frequently
(e.g. more than once on every trip) without any
snow, rain, mud, or other obstruction, 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
displays “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 temporarily
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
In certain driving situations, ACC may have
detection issues. In these cases, ACC may
brake late or unexpectedly. The driver needs to
stay alert and may need to intervene.
Towing A Trailer
Towing a trailer is not advised when using ACC.
Offset Driving
ACC may not detect a vehicle in the same lane
that is offset from your direct line of travel, or a
vehicle merging in from a side lane. There may
not be sufficient distance to the vehicle ahead.
The offset vehicle may move in and out of the
line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.

Offset Driving Condition Example

Turns And Bends
When driving on a curve with ACC engaged, the
system may decrease the vehicle speed and
acceleration for stability reasons, with no target
vehicle detected. Once the vehicle is out of the
curve the system will resume your original set
speed. This is a part of normal ACC system
functionality.
NOTE:
On tight turns ACC performance may be limited.

PARKSENSE FRONT AND REAR PARK ASSIST
— IF EQUIPPED
The ParkSense Park Assist system provides
visual and audible indications of the distance
between the rear and/or front fascia and a
detected obstacle when backing up or moving
forward (e.g. during a parking maneuver). Refer
to “ParkSense System Usage Precautions” in
this section for limitations of this system and
recommendations.
ParkSense will retain the system state (enabled
or disabled) from the previous ignition cycle
when the ignition is changed to the ON/RUN
position.

ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If ParkSense is
enabled at one of these gear selector positions,
the system will remain active until the vehicle
speed is increased to approximately 7 mph
(11 km/h) or above. The system will become
active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h).

PARKSENSE SENSORS
The four ParkSense sensors, located in the rear
fascia/bumper, monitor the area behind the
vehicle that is within the sensors’ field of view.
The sensors can detect obstacles from
approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction, depending
on the location, type and orientation of the
obstacle.
The six ParkSense sensors, located in the front
fascia/bumper, monitor the area in front of the
vehicle that is within the sensors’ field of view.
The sensors can detect obstacles from
approximately 12 inches (30 cm) up to
47 inches (120 cm) from the front fascia/
bumper in the horizontal direction, depending
on the location, type and orientation of the
obstacle.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen will only be
displayed if Sound and Display is selected from

178STARTING AND OPERATING
PARKSENSE DISPLAY
The warning display will turn on indicating the
system status when the vehicle is in REVERSE,
or when the vehicle is in DRIVE and an obstacle
has been detected.
The system will indicate a detected obstacle by
showing a single arc in one or more regions
based on the obstacle’s distance and location
relative to the vehicle.
If an obstacle is detected in the center rear
region, the display will show a single solid arc in
the center rear region and will produce a
one-half second tone. As the vehicle moves
closer to the obstacle, the display will show the
single arc moving closer to the vehicle and the
sound tone will change from slow, to fast, to
continuous. If an obstacle is detected in the left and/or right
rear region, the display will show a single
flashing arc in the left and/or right rear region
and will produce a fast sound tone. As the
vehicle moves closer to the obstacle, the
display will show the single arc moving closer to
the vehicle and the tone will change from fast to
continuous.
If an obstacle is detected in the center front
region, the display will show a single arc in the
center front region. As the vehicle moves closer
to the obstacle, the display will show the single
arc moving closer to the vehicle. A fast sound
tone will be produced when reaching the
second flashing arc and will change to a
continuous sound tone when the first flashing
arc appears.
If an obstacle is detected in the left and/or right
front region, the display will show a single
flashing arc in the left and/or right front region
and will produce a fast sound tone. As the
vehicle moves closer to the obstacle, the
display will show the single arc moving closer to
the vehicle and the tone will change from fast to
continuous.
